Open back headphones remain the go-to choice for audiophiles who want a natural, spacious soundstage that closed-back designs simply can’t match. After comparing 14 leading models, the Sennheiser HD 600 earns my best overall pick for its famously accurate midrange and reference tuning that has held up for decades. If your budget is tighter, the Sennheiser HD 560S delivers remarkably neutral sound at an accessible price, while the Sennheiser HD 660S2 offers a richer, more bass-forward take on the classic HD 650 formula for listeners who want more low-end warmth. The main tradeoffs you’ll face in this category are impedance and amplification requirements, comfort during long listening sessions, and whether you prefer analytical accuracy or a more musical presentation. Keep reading for the full breakdown of all 14 models and which one fits your ears, gear, and budget.

Key Takeaways
- Sennheiser dominates this roundup with seven of the 14 spots, and its HD 600/650 family remains the reference standard for midrange accuracy — but the lineup splits clearly between neutral monitors (HD 560S, HD 600) and warmer, bass-tilted models (HD 660S2).
- Impedance is the biggest hidden cost: 250-ohm models like the beyerdynamic DT 990 Pro and 300-ohm Sennheisers need a dedicated headphone amp to sound their best, while low-impedance options like the DT 990 Pro X and Philips Fidelio X2HR run well from phones and laptops.
- The beyerdynamic DT 990 twins highlight how the same chassis sounds different with different drivers: the 250-ohm version is brighter and more energetic, while the 48-ohm Pro X is smoother and easier to drive.
- The Focal Elear and Audio-Technica ATH-ADX7000 sit at the premium end and offer the most dynamic punch and detail retrieval here, but both demand careful source matching to justify their step-up positioning.
- For beginners, the HD 599 and HD 599SE are essentially the same headphone in different colors — the real entry-level decision is between that relaxed tuning and the more neutral, analysis-friendly HD 560S.

More Details on Our Top Picks
ASUS ROG Kithara Gaming/Audiophile Open-Back Wired Headphones with Mic
Most open-back headphones force a choice between hi-fi listening and communication — the Kithara refuses to compromise. Its 100mm HIFIMAN planar magnetic drivers deliver the low-distortion, spacious presentation audiophiles want, while the full-band MEMS boom mic handles voice duties that the Sennheiser HD 600 and HD 560S simply can’t. The included 4.4mm balanced, 3.5mm, 6.3mm, and USB-C plugs mean it plugs into everything from a balanced DAC stack to a console controller without adapters. Compared with the beyerdynamic DT 990 Pro, its planar drivers give tighter, faster bass response, though purists will notice the ROG tuning prioritizes engagement over the DT 990 Pro’s flatter studio signature. The tradeoffs are familiar: open-back leakage makes it a poor choice for shared rooms, and there’s no wireless fallback.
Pros:- Large 100mm HIFIMAN planar magnetic drivers with low distortion
- Full-band MEMS boom mic rated 20Hz–20kHz for clear voice
- Four connection options including 4.4mm balanced and USB-C
- Eight-level adjustable headband and extra ear pads included
Cons:- Open-back design leaks sound and offers almost no isolation
- Wired-only — no wireless option for casual or mobile use
Best for: Gamers and desk-based listeners who want genuine audiophile planar sound without giving up a quality boom microphone
Not ideal for: Commuters or open-office users — the open-back design leaks sound in both directions and the wired-only design tethers you to a desk
- Driver:100mm HIFIMAN planar magnetic (ROG-tuned)
- Design:Open-back over-ear
- Microphone:Full-band MEMS boom mic, 20Hz–20kHz
- Plugs:4.4mm balanced, 3.5mm, 6.3mm, USB-C adapter
- Headband:Eight-level adjustable, soft padding
- Extras:Extra ear pads included
Our verdict“The rare open-back that serves both a hi-fi shelf and a gaming desk, making it the obvious pick if a microphone is non-negotiable.”
Audio-Technica ATH-ADX7000 Open-Back Headphones
At 490 ohms, the ATH-ADX7000 is the most demanding headphone in this lineup — and one of the most rewarding if your gear can feed it. The 58mm HXDT driver paired with a precision-machined aluminum baffle targets the detail retrieval and wide soundstage that flagship buyers expect, and the 275g weight keeps marathon sessions comfortable. Where the Sennheiser HD 600 leans warm and forgiving, this model is built for listeners who want to hear everything, warts and all. Japanese manufacturing adds a level of build refinement few competitors match at any price. The reality check: that 490-ohm impedance means a phone or laptop jack will barely drive it — a dedicated high-voltage amplifier is effectively mandatory, adding real cost on top of an already premium purchase.
Pros:- 58mm HXDT dynamic driver tuned for detail and natural tone
- Precision-machined aluminum baffle reduces resonance
- Featherweight 275g build for extended sessions
- Made in Japan with flagship-level fit and finish
Cons:- 490-ohm impedance demands high-performance amplification
- Open-back design provides almost no isolation from ambient noise
Best for: Seasoned audiophiles with a high-current headphone amplifier who want maximum transparency and detail
Not ideal for: Anyone without serious amplification — at 490 ohms, plugging into a laptop or phone produces thin, lifeless sound
- Type:Open-back over-ear headphones
- Driver:58mm HXDT dynamic transducer
- Impedance:490 ohms
- Weight:275 g
- Baffle:Precision-machined aluminum
- Country of manufacture:Japan
Our verdict“A specialist’s flagship that rewards a serious amp chain — skip it unless your source equipment is already up to the task.”
Sennheiser HD 600 Audiophile Open-Back Dynamic Headphones
Decades after launch, the HD 600 remains the headphone other open-backs are measured against — that’s why it earns the top spot. Its computer-optimized magnet system and aluminum voice coils produce the natural, spatial imaging that made it a mastering-room staple, and the diaphragm design eliminates standing waves for remarkably clean mids. Against the beyerdynamic DT 990 Pro, the HD 600 is the more neutral and less fatiguing listen; against the HD 560S, it offers a touch more refinement and midrange richness, justifying the step up for serious listeners. The detachable Kevlar-reinforced cable means longevity the DT 990 Pro’s fixed coiled cable can’t match. Be realistic about the demands: 300 ohms of impedance requires a dedicated amp, there’s no microphone, and the open-back design belongs in a quiet, private room.
Pros:- Reference-grade neutral tuning trusted by mastering engineers
- Lightweight 260g design comfortable for long sessions
- Detachable Kevlar-reinforced OFC cable for long-term durability
- Advanced diaphragm design eliminates standing waves
Cons:- 300-ohm impedance requires dedicated amplification
- Open-back design leaks sound with no isolation
- No built-in microphone for calls or gaming
Best for: Dedicated home listeners and critical listeners who want a proven reference sound and already own (or will buy) amplification
Not ideal for: Casual listeners plugging straight into a phone — the 300-ohm impedance and lack of mic make it the wrong tool
- Type:Open-back dynamic over-ear
- Impedance:300 ohms
- Frequency response:12–39,000 Hz
- THD:0.1%
- Weight:260 g
- Cable:Detachable Kevlar-reinforced OFC copper
- Connectors:1/4″ and 1/8″ jacks
- Country of manufacture:Ireland
Our verdict“If you want the safest long-term bet in open-back hi-fi and have an amp to drive it, the HD 600 is the one to beat.”
Sennheiser HD 560S Open-Back Over-Ear Wired Headphones
The HD 560S is the smartest entry point in this roundup because it delivers the Sennheiser open-back signature — natural accuracy, wide soundstage, lifelike depth — without the amplification burden of its bigger siblings. Angled drivers and a polymer-blend membrane keep bass controlled and imaging coherent, and its friendlier impedance means it runs reasonably well from a computer or interface, where the HD 600 would sound starved. Compared directly, it gives up some midrange refinement and build prestige to the HD 600, and the ATH-ADX7000 out-resolves it — but neither matters if this is your first serious headphone. The honest limitations: it’s wired-only like everything here, and the open-back design still leaks sound, so it shares the quiet-room requirement of the DT 990 Pro despite the lower price.
Pros:- Natural, accurate reference tuning at an accessible price
- Wide soundstage with lifelike depth from angled drivers
- Extended low-end reach with controlled bass
- Easier to drive than high-impedance flagships like the HD 600
Cons:- Open-back design provides minimal sound isolation
- Wired connection limits mobility and casual use
- Less refined midrange and build than step-up models
Best for: First-time audiophiles and students who want genuine reference sound and a wide soundstage on a modest budget
Not ideal for: Anyone wanting isolation or wireless freedom — the open back leaks sound and the cable keeps you desk-bound
- Design:Open-back, over-ear
- Connectivity:Wired
- Connector:1/4-inch
- Drivers:Angled dynamic with polymer-blend membrane
- Weight:600 g (packaged)
- Warranty:2 years
Our verdict“The best pound-for-pound open-back here for newcomers — a real audiophile sound without the amp requirement or flagship price.”
beyerdynamic DT 990 Pro Open-Back Studio Headphones, 250 Ohm
Where the HD 600 flatters and the ASUS Kithara entertains, the DT 990 Pro tells the truth with a wide, natural stereo image built for mix decisions. Its 5–35,000 Hz frequency response and analytical German-built tuning expose flaws in recordings that smoother headphones hide, which is exactly why studios keep a pair on the hook. The replaceable velour ear pads make long-term ownership cheap, unlike sealed designs with glued padding. The catch is twofold: the 250-ohm impedance needs a headphone amp or audio interface for proper volume — a phone will not do — and its famously bright treble can fatigue listeners who prefer the HD 560S’s gentler top end. The fixed 3m coiled cable also means a damaged cable is a repair, not a quick swap like the HD 600’s detachable one.
Pros:- Wide, natural stereo image ideal for mix decisions
- Soft, replaceable velour ear pads extend lifespan
- Extended 5–35,000 Hz frequency response reveals detail
- German-made build with 2-year warranty
Cons:- 250-ohm impedance requires an amplifier or audio interface
- Not suitable for direct use with a phone
- Fixed coiled cable can’t be easily replaced if damaged
Best for: Home studio owners and producers who need an analytical open-back for mixing, mastering, and tracking decisions
Not ideal for: Mobile listeners and treble-sensitive ears — it needs an amp and its bright tuning can fatigue during casual listening
- Type:Open-back dynamic headphones
- Impedance:250 ohms
- Frequency response:5–35,000 Hz
- Cable:3m fixed coiled
- Ear pads:Replaceable grey velour
- Included accessory:1/4-inch adapter
- Country of manufacture:Germany
- Warranty:2 years
Our verdict“The studio workhorse of this lineup — buy it for making music, not for relaxing with a phone in hand.”
beyerdynamic DT 990 Pro X (48 Ohm) Open-Back Studio Headphones
The DT 990 Pro X solves the biggest practical problem with open-back headphones: impedance. At 48 ohms, it runs at full volume straight from a laptop, phone, or console, unlike the classic beyerdynamic DT 990 Pro 250 Ohm, which really needs a headphone amp to shine. The STELLAR.45 driver delivers beyerdynamic’s signature analytical detail with a wide, natural soundstage that works for both mixing and pure listening. The detachable mini-XLR cable is a meaningful upgrade over the fixed cable on the older model, since cables are usually the first thing to fail. The tradeoff is the familiar one for the category — sound leaks out freely, and there’s effectively no isolation from a noisy room.
Pros:- No headphone amp needed thanks to the 48-ohm impedance
- STELLAR.45 driver delivers high-resolution, analytical detail
- Detachable mini-XLR cable is replaceable if damaged
- Wide, natural soundstage suited to mixing and critical listening
Cons:- Leaks sound noticeably, audible to people nearby
- Almost no passive noise isolation
Best for: Producers and audiophiles who want reference-grade open-back sound without buying a headphone amp
Not ideal for: Anyone in a shared office or quiet public space — the open-back design leaks sound both ways
- Impedance:48 Ohms
- Type:Open-back
- Driver:STELLAR.45 dynamic
- Connectivity:Wired, 3.5 mm with 6.35 mm adapter
- Cable:Detachable 3 m mini-XLR
- Ear Pads:Velour
- Warranty:2 years
- Country of Origin:Germany
Our verdict“The easiest entry into serious open-back sound if you don’t own an amp.”
Philips Fidelio X2HR Open-Back Wired Headphones
The Fidelio X2HR remains one of the most sensible ways to get a genuinely wide open-back presentation without paying audiophile-tier money. Its 50 mm neodymium drivers with LMC diaphragms produce a big, engaging soundstage that, while less neutral than the Sennheiser HD 560S, is more fun for casual, long listening sessions. Practical details matter here: replaceable memory foam ear pads, a detachable 3 m oxygen-free cable, and a self-adjusting headband that distributes weight well. Compared with the beyerdynamic DT 990 Pro X, the X2HR trades some analytical precision for a warmer, more relaxed character. Like everything in this category, isolation is minimal and the wired-only design won’t suit anyone wanting wireless freedom.
Pros:- Hi-Res Audio certified 50 mm neodymium drivers
- Replaceable memory foam ear pads extend lifespan
- Detachable 3 m cable with 6.3 mm adapter included
- Self-adjusting headband is comfortable for long sessions
Cons:- Tuning is warmer and less neutral than true reference headphones
- Wired only with no isolation from external noise
Best for: Budget-conscious listeners who want a spacious, comfortable open-back sound for home listening
Not ideal for: Studio engineers needing a strictly neutral reference — the tuning leans warm and fun rather than flat
- Type:Over-ear wired, open-back
- Driver Size:50 mm
- Drivers:Neodymium with LMC diaphragm
- Cable:Detachable 3 m oxygen-free cable
- Connectors:3.5 mm stereo, 6.3 mm adapter included
- Ear Pads:Replaceable memory foam with breathable velour
- Certification:Hi-Res Audio
Our verdict“A comfortable, engaging open-back that punches above its price for pure music enjoyment.”
Audio-Technica ATH-R50x Open-Back Reference Headphones
At just 207 grams, the ATH-R50x is the lightest serious reference option in this lineup, and that weight difference is immediately noticeable during long mixing sessions. The fully open-back design eliminates internal resonance, giving a quick transient response and a soundstage that feels more open than the beyerdynamic DT 990 Pro X, though both target the same production audience. Audio-Technica tunes this one with extended bass and an accurate midrange, a combination that makes vocals and instruments sit honestly in a mix. Including two detachable cables (3 m and 1.2 m) plus a carrying pouch is a thoughtful touch — the short cable suits desktop use while the long one reaches across a studio. The proprietary 2.5 mm twist-lock connector is the main compromise, being harder to replace than standard cables.
Pros:- Featherweight 207 g build reduces fatigue in long sessions
- Accurate midrange with extended bass for production work
- Two detachable cables plus adapter and pouch included
- Fully open-back design delivers quick, clean transients
Cons:- Proprietary 2.5 mm twist-lock connector is harder to replace than standard cables
- Leaks sound and provides almost no isolation
Best for: Producers and mixers who wear headphones for hours and want a featherweight, neutral reference
Not ideal for: Travelers or commuters — the open design leaks sound and the twist-lock cable is less universal for replacements
- Type:Open-back reference headphones
- Weight:207 g
- Cable 1:3.0 m with 3.5 mm gold-plated plug
- Cable 2:1.2 m with 3.5 mm gold-plated plug
- Earcup Connector:2.5 mm twist-lock (left earcup)
- Included:6.3 mm adapter, carrying pouch
Our verdict“The pick for studio professionals who prioritize comfort and honest mids over convenience.”
Sennheiser HD 505 Wired Open-Back Audiophile Headphones
The HD 505 occupies a smart middle ground in Sennheiser’s lineup: more refined than the HD 599 thanks to its advanced laminate diaphragm, but far more affordable than the HD 660S2. The result is crisp highs, clear mids, and controlled bass — a tuning that works equally well for music, gaming, and light audio work. What makes this model stand out is comfort: the lightweight headband and plush velour pads disappear on your head over multi-hour sessions, matching the easy wear of the Philips Fidelio X2HR but with a cleaner, more neutral balance. The 1.8 m cable is shorter than the 3 m runs on studio models, which is actually a plus at a desk and a limitation on a couch. As always with open-backs, pass on this if your environment is noisy or shared.
Pros:- Laminate diaphragm delivers crisp highs and clear, balanced mids
- Natural, airy soundstage suits music and gaming alike
- Featherweight headband and plush velour pads for all-day comfort
- Compatible with the wider HD 500 series accessory ecosystem
Cons:- Leaks sound and offers little noise isolation
- 1.8 m cable may be too short for roomier setups
Best for: Listeners and gamers who want airy, detailed open-back sound for marathon sessions without fatigue
Not ideal for: Anyone wanting wireless convenience or usable isolation from background noise
- Brand:Sennheiser
- Type:Wired open-back over-ear
- Diaphragm:Advanced laminate diaphragm
- Cable Length:1.8 m
- Connector:3.5 mm
- Ear Pads:Plush velour
- Included:Drawstring bag
- Compatibility:HD 500 series cables and accessories
Our verdict“A comfortable, versatile open-back that bridges Sennheiser’s casual and audiophile lines.”
Sennheiser HD 660S2 Open-Back Audiophile Headphones
The HD 660S2 is the enthusiast’s choice of this batch, refining the legendary HD 650 formula with 42 mm transducers and ultra-light aluminum voice coils. The headline improvement is bass: controlled sub-bass extension down to 27.5 Hz, an area where the HD 650 and even the HD 600 famously roll off. Mids remain rich and vocals remain the star, which is exactly what fans of this family expect. Compared with the HD 505, the step up in resolution and refinement is clear, though the price gap is just as obvious. Build quality is premium, crafted in Germany and Ireland, and the breathable cushions support hours of listening. The included 4.4 mm balanced cable shows Sennheiser expects you to pair it with serious source gear — this is not a plug-into-your-phone headphone.
Pros:- Rich, natural mids with detailed highs — the classic HD-family signature
- Sub-bass extends to 27.5 Hz, a real upgrade over the HD 650
- Includes both 6.3 mm and 4.4 mm balanced cables
- Premium build crafted in Germany and Ireland
Cons:- Priced far above the rest of this batch — diminishing returns for casual setups
- Wired only, and needs quality amplification to perform at its best
Best for: Dedicated audiophiles with quality source gear who want reference-class mids plus real sub-bass extension
Not ideal for: Casual listeners or anyone without a decent amp/DAC — you’d be paying for performance you can’t fully hear
- Brand:Sennheiser
- Type:Open-back over-ear headphones
- Transducer Size:42 mm
- Voice Coil:Ultra-light aluminum
- Low-Frequency Extension:27.5 Hz
- Included Cables:6.3 mm (1.8 m) and 4.4 mm balanced (1.8 m)
- Included Accessories:6.3 mm to 3.5 mm adapter, carry pouch
- Warranty:2 years
Our verdict“The premium pick for listeners ready to build a system around their headphones.”
Focal Elear High-Fidelity Open-Back Circum-Aural Headphones
The Focal Elear earns its place as the luxury pick of this lineup, borrowing driver architecture and design cues directly from Focal’s flagship Utopia. Its aluminum/magnesium ‘M’-shaped dome drivers deliver a punchy, dynamic character that feels more visceral than the smoother, more laid-back Sennheiser HD 650 — listeners who crave energy and impact in their music will notice the difference immediately.
Compared with the Sennheiser HD 599, the Elear is in another league on build: the solid aluminum yoke and leather headband feel like a piece of high-end equipment rather than plastic hi-fi gear. The tradeoff is real, though — this is the heaviest commitment here in both weight (5.7 pounds shipped) and seriousness of purpose, and like every open-back, it leaks sound freely. This option makes the most sense for dedicated listening rooms, not commutes.
Pros:- Exclusive aluminum/magnesium ‘M’-shaped dome drivers derived from the Utopia line
- Premium solid aluminum yoke and leather headband built to last decades
- Memory foam ear cushions keep long sessions comfortable
- Designed and manufactured in France with decades of acoustic expertise
Cons:- Heavy at 5.7 pounds, which some listeners feel during extended sessions
- Sound leakage makes it unusable in shared or noisy spaces
- Benefits greatly from quality amplification, adding to the total investment
Best for: Established audiophiles who want flagship-inspired Focal engineering and tank-like build for dedicated home listening
Not ideal for: Casual listeners or anyone on a starter budget — it demands serious source equipment to justify its character
- Brand:Focal
- Model Number:EELECAS1
- Type:Open-back circum-aural
- Driver:Aluminum/magnesium ‘M’-shaped dome
- Materials:Aluminum yoke, leather headband, memory foam cushions
- Weight:5.7 pounds
- Warranty:2 years
Our verdict“The Elear is for the listener ready to make open-back listening a centerpiece hobby rather than a casual pastime.”
Sennheiser HD 599 Open-Back Wired Audiophile Headphones, Ivory
The Sennheiser HD 599 stands out as the comfort champion of this roundup. Its velour ear pads and light clamping force make multi-hour listening sessions effortless — something the heavier Focal Elear simply can’t match. The aluminum voice coils keep efficiency high, so this model sings even straight from a phone or laptop, unlike the harder-to-drive HD 650.
What you give up is refinement at the extremes. The HD 599’s spatial presentation is natural and pleasant, but it lacks the razor-sharp low-distortion precision of the HD 650’s matched drivers. That’s a fair trade for buyers who value comfort and plug-and-play simplicity over reference accuracy. The inclusion of two detachable cables — a long 6.3mm run for home gear and a short 3.5mm for portable use — adds everyday practicality that most competitors here don’t offer in one box.
Pros:- Velour ear pads and light clamp pressure excel over long sessions
- High-efficiency transducers work well without a dedicated amp
- Two detachable cables cover both home and portable setups
- Replaceable pads extend the headphone’s usable lifespan
Cons:- Open-back design leaks sound both ways, ruling out offices and transit
- Wired only — no Bluetooth option for wireless listeners
- Less detailed and resolving than higher-tier open-backs like the HD 650
Best for: Listeners who prioritize all-day comfort and want open-back sound without needing an amplifier
Not ideal for: Analytical listeners chasing reference-level detail — the HD 650 outclasses it on precision
- Brand:Sennheiser
- Model:HD 599
- Type:Open-back, over-ear, wired
- Transducers:Sennheiser engineered with aluminum voice coils
- Ear Pads:Velour, replaceable
- Cables:3m detachable (6.3mm); 1.2m detachable (3.5mm)
- Color:Ivory
- Warranty:1 year
Our verdict“The HD 599 is the pick for comfort-first listeners who want relaxed, spacious sound without extra equipment.”
Sennheiser HD 599SE Open-Back Wired Headphones, Black
The HD 599SE is essentially the HD 599 formula in a stealthy black finish, and it carves out its own role as the best do-everything option for buyers who want one headphone for music, movies, and gaming at a desk. Its spacious soundstage and balanced tuning make it more forgiving and versatile than the analytical beyerdynamic DT 990 Pro, which can push treble forward enough to fatigue some listeners over long evenings.
Compared with its ivory sibling, the SE swaps aesthetics and gains a longer two-year warranty — functionally the same headphone, so the choice comes down to look and coverage. Like the Sennheiser HD 560S, it drives easily from modest sources, but the 599SE leans warmer and more relaxed. The tradeoff: bass is controlled rather than powerful, and the wired-only design tethers you to your device.
Pros:- Spacious, natural soundstage suited to both music and film
- Balanced tuning with detailed highs and controlled bass
- Plush velour pads designed for extended comfort
- Two detachable cables for flexible device pairing
Cons:- Open-back leakage makes it impractical outside quiet rooms
- Bass response is restrained compared with closed-back alternatives
- Wired connection limits movement around a desk or room
Best for: Buyers wanting one comfortable open-back headphone for mixed music, film, and desktop use
Not ideal for: Bass lovers and wireless-first listeners — it stays polite in the low end and offers no Bluetooth
- Brand:Sennheiser
- Model:HD 599 SE
- Type:Open-back wired
- Color:Black
- Cables:3m with 6.3mm plug; 1.2m with 3.5mm plug
- Ear Pads:Velour
- Warranty:2 years
Our verdict“The HD 599SE is the sensible all-rounder for listeners who want open-back airiness in a single do-it-all headphone.”
Sennheiser HD 650 Audiophile Hi-Res Open Back Dynamic Headphones
The Sennheiser HD 650 remains the benchmark against which open-backs are judged, and it claims the reference-sound crown here. Its hand-matched drivers and acoustic silk damping push total harmonic distortion down to a remarkable 0.05% — a level of cleanliness the HD 599 and HD 599SE can’t approach, and one that rivals the pricier HD 660S2 in midrange purity.
Where the HD 600 is often called the more neutral studio tool, the HD 650 leans slightly warmer and more forgiving, which makes it a better long-session companion for pure enjoyment. The catch is meaningful: its high impedance wants a headphone amplifier or DAC to sound its best, so budget for one. Plugged straight into a phone, it underperforms its potential — the opposite of the easy-driving HD 599. For listeners building a serious desktop chain, this is the foundation pick.
Pros:- Hand-selected matched driver pairs for precise stereo imaging
- Extremely low 0.05% THD from acoustic silk damping
- Wide 10 Hz – 39,500 Hz frequency response
- Comfortable enough for marathon listening sessions
Cons:- Needs a headphone amp or DAC to reach its full potential
- Open-back design leaks sound and isolates almost nothing

Our verdict“The HD 650 is the definitive choice for amplified-desk audiophiles who prioritize midrange accuracy above all else.”
How We Picked
I evaluated each model against what actually matters to audiophile listeners: tuning accuracy and timbre (does the headphone reproduce voices and instruments naturally?), soundstage and imaging (the core reason to choose open back in the first place), comfort over multi-hour sessions, build and repairability, and how demanding each model is to drive. That last factor matters more than most buyers expect — a technically excellent 300-ohm headphone plugged into a phone can sound worse than a modest model properly amplified.
Ranking also reflects role differentiation rather than a single quality score. The HD 600 takes best overall because its balance of accuracy, comfort, and long-term support is unmatched for the widest range of listeners. Value picks prioritize performance-per-dollar among easy-to-drive models, premium picks had to justify their price with audible gains in dynamics and detail, and beginner picks favor forgiving tuning and broad source compatibility. Every model here had to show a genuine strength — none earned a place on brand reputation alone.
Factors to Consider When Choosing Open Back Headphones For Audiophiles
Before choosing a specific model, it helps to understand the forces that shape open back headphone performance. The factors below explain why two similarly priced headphones can sound completely different, and where buyers most often go wrong.Impedance and Amplification: The Real Budget Decision
Impedance determines how much voltage your headphone output needs to deliver, and it’s the factor most buyers underestimate. High-impedance models like the 300-ohm Sennheiser HD 600 and HD 650 or the 250-ohm beyerdynamic DT 990 Pro are engineered to shine when driven by a dedicated amplifier — they reward you with tighter bass and better control, but sound flat and lifeless from a phone. Low-impedance designs such as the DT 990 Pro X (48 ohm) or the Philips Fidelio X2HR are built for direct connection to laptops, interfaces, and mobile devices. A common mistake is spending an entire budget on high-impedance headphones with nothing left for amplification. My rule of thumb: if you don’t own an amp and don’t plan to buy one, choose a low-impedance model even if a high-impedance rival measures better on paper.
Tuning Philosophy: Neutral Monitor vs. Musical Presentation
Open back headphones cluster into two broad camps, and knowing which camp you belong to narrows the field fast. Neutral monitors like the HD 600 and HD 560S aim for accuracy — vocals sit exactly where they were recorded, and nothing is flattered. Warmer, more musical tunings like the HD 660S2 or HD 599 add bass weight and smooth the top end, which is easier to live with for casual, relaxed listening. The beyerdynamic DT 990 line sits at the opposite extreme, with a bright, energetic treble that some listeners find exhilarating and others fatiguing over long sessions. There is no objectively correct answer here; the mistake is buying a bright analytical headphone when you mostly want to unwind with music, or buying a warm headphone when your goal is critical listening and mixing.
Soundstage and Imaging: Why Open Back Exists
The open back design trades isolation for air and spatial presentation, but not all open backs deliver this equally. Models with genuinely wide staging — the Fidelio X2HR and ATH-ADX7000 stand out here — place instruments around your head rather than between your ears, which transforms orchestral, acoustic, and live recordings. The classic Sennheiser HD 600-family trade some width for pinpoint central imaging and cohesion, a compromise many audiophiles actually prefer for vocals and small-ensemble music. If your library is mostly classical, jazz, or live albums, prioritize staging. If you listen to vocal-centric or studio music, intimate imaging may serve you better than raw width. Either way, remember the tradeoff that makes it all possible: everyone around you hears your music too.
Comfort and Weight for Long Sessions
Audiophile listening sessions tend to run long, and comfort failures end more headphone relationships than sound flaws do. Clamping force, pad material, and weight matter more than headband styling. The Sennheiser HD 5xx series is famously light with a gentle clamp, making it a safe choice for hours of wear, while beyerdynamic’s firmer clamp and velour pads suit some head shapes perfectly and cause pressure points on others. Heavier premium models like the Focal Elear use substantial metal construction that feels superb but can grow noticeable past the two-hour mark. One practical point: ear pads compress and wear out over years, and replacement pad availability varies by brand — Sennheiser and beyerdynamic both have long-term parts support, which quietly extends the life of your purchase.
Cables, Replaceability, and Long-Term Ownership
Open back audiophile headphones are often kept for a decade or more, so serviceability is a real value factor, not a nicety. Models with detachable cables — which includes nearly everything in this roundup — can survive a cable failure that would otherwise end a headphone’s life. Sennheiser’s HD 600-series uses a standard two-pin connector with inexpensive, widely stocked replacements, and its drivers and pads are also user-replaceable. Fixed-cable designs save a little cost up front but gamble the whole product on one component. If you plan to keep headphones long-term or experiment with aftermarket cables, check connector type and parts availability before buying, not after something breaks.
Matching Headphones to Your Source Chain
Your headphone is only one link in a chain that includes your DAC, amp, and even the recordings themselves. A resolving premium headphone like the Focal Elear or ATH-ADX7000 will faithfully expose every flaw in a poor source, which is why matching matters at the top end. At the other extreme, pairing a warm, forgiving model like the HD 599 with a modest dongle or laptop jack produces genuinely pleasant results with no further investment. Bright-tuned headphones benefit from slightly warmer sources; neutral headphones give you the most honest picture of what your gear contributes. The most common upgrade-path mistake is buying a flagship first and discovering your existing equipment can’t feed it — build the chain and the headphones together.
Frequently Asked Questions
Do I really need a headphone amp for 300-ohm models like the HD 600 or HD 650?
Strictly speaking, you need enough voltage swing, and many phone and laptop outputs fall short of driving 300-ohm headphones properly. Without adequate power you’ll get reduced dynamic contrast, soft bass, and the sense that the headphone sounds dull — which is how the myth that these Sennheisers are ‘boring’ often starts. A modest dedicated amp or a quality dongle DAC with a strong output typically transforms them. That said, if you have no intention of buying any amplification, you’re better served by the low-impedance models in this roundup, such as the HD 560S or DT 990 Pro X, which reach their intended performance from ordinary sources.
What’s the actual difference between the beyerdynamic DT 990 Pro and the DT 990 Pro X?
They share the same chassis and open back design, but the drivers and impedance differ, and that changes both the sound and the gear requirements. The original DT 990 Pro at 250 ohms has a bright, V-shaped presentation with energetic treble and needs amplification to deliver its best bass control. The DT 990 Pro X at 48 ohms uses the STELLAR driver from higher-tier beyerdynamic models, resulting in a smoother, more balanced tuning that runs well from portable sources. If you found the classic DT 990 too sharp, the Pro X addresses exactly that complaint — while listeners who love the aggressive original should stick with the 250-ohm version and amplify it properly.
Is the HD 650 worth the extra money over the HD 600, or the HD 660S2 over both?
All three are excellent, and the honest answer depends on what you listen to. The HD 600 is the most neutral and mid-focused of the three — the safest pick for vocal, acoustic, and classical listening. The HD 650 trades a touch of that neutrality for slightly warmer, more relaxed presentation that many find easier for long sessions. The HD 660S2 goes further, adding noticeably more bass extension and a darker overall character, which suits electronic, rock, and hip-hop listeners who love the Sennheiser midrange but wanted low-end weight. None is a strict upgrade over the others; they’re three different voicings of the same comfort and build.
Are open back headphones a problem if I share a room or work near others?
Yes, this is the category’s fundamental tradeoff — open back designs leak sound in both directions, so people nearby will hear your music at moderate volumes, and you’ll hear them. In a quiet, private listening space this is a non-issue and the sonic benefits are worth it. In a shared office, busy household, or commuter setting, open backs are the wrong tool regardless of how good they sound. Some buyers solve this by keeping a cheap closed-back pair for noisy environments and reserving open backs for focused home listening, which is a more sensible split than compromising on one headphone for both jobs.
The HD 599 and HD 599SE look identical apart from color — which should I buy?
You’re right to notice: they are the same headphone acoustically, with the SE being the black special edition of the ivory original. Sound, drivers, comfort, and cable are functionally identical, so this comes down to aesthetics and occasionally small price differences between the two listings at any given time. Choose whichever finish suits your setup and costs less when you buy. The more meaningful decision for entry-level buyers is actually one tier up: whether to get the relaxed, warm HD 599 voicing at all, or step to the HD 560S, which is more neutral and analytical for a modest increase — that choice affects your listening far more than color ever will.
Conclusion
With 14 strong options, the right pick comes down to your gear, your budget, and the sound signature you enjoy. For best overall, the Sennheiser HD 600 remains the most complete audiophile headphone at its price — accurate, comfortable, endlessly repairable, and amplified easily by modest gear. The best value pick is the Sennheiser HD 560S, which brings genuinely neutral, reference-grade sound to buyers who don’t want to buy an amp, while the beyerdynamic DT 990 Pro X is the value choice for anyone wanting a livelier, easier-driving alternative to the classic 250-ohm model.
At the premium end, the Sennheiser HD 660S2 is the pick for listeners who want the HD 650 character with real bass extension, and the Focal Elear offers the most dynamic punch here if you have the source chain to feed it, with the ATH-ADX7000 as the premium choice for detail and light weight. For beginners, the HD 599/599SE is the gentlest on-ramp to open back listening, and the Philips Fidelio X2HR suits specific needs like wide soundstage on a budget without amplification. For gaming-with-audiophile-priorities buyers, the ASUS ROG Kithara adds a mic and platform compatibility without abandoning open back sound, and the ATH-R50x serves critical listeners who want reference monitoring flavor at a midrange price. Match the model to your source and preferred tuning, and any of these will reward you with the open, natural sound that keeps audiophiles loyal to this design.
