Top 10 Open-Back Audiophile Headphones in 2027 — Best Overall + Best Value
*Published June 23, 2026 · Updated June 23, 2026*
Direct Answer
The best open-back audiophile headphone you can buy in 2027 is the Sennheiser HD 800S — its 56mm ring-radiator driver throws the widest, most precise soundstage of any dynamic headphone, and after years on the market it remains the reference critical-listening tool against which everything else is measured.
Our 🏆 BEST OVERALL pick reflects that pedigree, with the caveat that its 300Ω impedance demands a real desktop amplifier.
For listeners who want most of that magic for a fraction of the money, the Sennheiser HD 660S2 is our 💎 BEST VALUE choice. At around $499 it delivers the famous 600-series midrange with genuine sub-bass authority down to 27.5Hz, and it pairs with almost any decent amp.
If you only buy one pair of serious open-back headphones this year, the HD 660S2 is the safest spend.
Open-back designs let air pass through the rear of the driver, which kills internal resonance and produces the airy, speaker-like staging audiophiles chase. The trade-off is zero isolation and sound leakage — these are home headphones, not subway headphones. The list below mixes dynamic and planar-magnetic drivers across price tiers so you can match a headphone to your budget and your amplifier.
1. Sennheiser HD 800S 🏆 BEST OVERALL
Driver: 56mm dynamic ring-radiator | Price: ~$1,699 | Impedance: 300Ω | Best for: critical listening, soundstage
The HD 800S is the headphone other headphones get compared to. Its oversized 56mm ring-radiator driver and angled baffle produce a soundstage so wide and precisely layered that it can re-create the front-row geometry of an orchestra. The "S" revision tamed the original HD 800's treble peak with an internal absorber, giving you the staging without the glassy edge.
This is a tool for people who analyze recordings as much as they enjoy them. It is unforgiving of bad sources and bad masters, and at 300Ω it genuinely needs a competent desktop amplifier to come alive. Feed it well and nothing in this list resolves micro-detail with more composure.
Pros:
- Reference-class soundstage width and imaging precision
- Refined, extended treble after the "S" absorber fix
- Superb detail retrieval and instrument separation
- Comfortable for marathon listening sessions
Cons:
- Requires a serious amp; portable sources fall flat
- Bass is accurate but lean for bass-heads
Verdict: The end-game dynamic open-back for analytical listeners with a proper amp.
2. Sennheiser HD 660S2 💎 BEST VALUE
Driver: 42mm dynamic | Price: ~$499 | Impedance: 300Ω | Best for: all-rounder, vocals
The HD 660S2 is the most complete package in Sennheiser's legendary 600 series. It keeps the lush, natural midrange that made the HD 650 a cult classic, then fixes the family's one weakness: the new driver reaches down to 27.5Hz with real authority instead of rolling off in the sub-bass.
Despite the 300Ω rating, its tuning makes it sound full off a wide range of amps, from a $99 dongle-class desktop unit to a flagship. For new buyers choosing among the 600, 650, and 660S2, this is the one to get unless you specifically want the drier 600 or warmer 650. It is the rare audiophile headphone that flatters nearly every genre.
Pros:
- Iconic 600-series midrange and vocal texture
- Genuine sub-bass extension new to the family
- Forgiving of average amps and recordings
- Built to last with replaceable parts
Cons:
- Soundstage is intimate, not expansive
- Still benefits from a dedicated amp at 300Ω
Verdict: The smartest single purchase in audiophile open-backs — do-it-all sound at a fair price.
3. HiFiMan Sundara
Driver: planar-magnetic | Price: ~$299 | Impedance: 32Ω | Best for: budget planar entry
The Sundara is the headphone that proved planar-magnetic sound no longer requires a fortune. Its thin diaphragm delivers fast transients and a clean, detailed presentation that punches well above its $299 price, which has dropped roughly $200 since launch.
The 32Ω impedance hides the fact that, at 94dB sensitivity, the Sundara really wants amplification to deliver dynamic swings properly. Give it some current and you get planar speed and clarity that embarrasses many dynamic headphones twice the cost.
Pros:
- Planar speed and detail at a remarkable price
- Clean, neutral-leaning tuning
- Comfortable metal-and-leather build
- Excellent gateway into planar magnetics
Cons:
- Low sensitivity means it needs real power
- Bass can feel polite without a strong amp
Verdict: The best-value planar entry point and a giant-killer for the money.
4. Sennheiser HD 600
Driver: 42mm dynamic | Price: ~$280 | Impedance: 300Ω | Best for: neutral reference, classical
The HD 600 is the closest thing the hobby has to a permanent reference. For decades it has been the headphone reviewers reach for to hear a recording honestly, with a neutral, slightly midrange-forward voicing that flatters acoustic music and classical especially well.
At around $280 it is one of the great bargains in audio. Like its siblings it is 300Ω and rewards a clean amp, but its forgiving treble and natural tone make it endlessly listenable rather than fatiguing.
Pros:
- Honest, neutral reference tuning
- Sublime midrange and vocal realism
- Decades-proven reliability and parts support
- Outstanding price-to-performance
Cons:
- Modest soundstage and sub-bass
- Needs an amp to reach full dynamics
Verdict: The neutral benchmark every audiophile should hear at least once.
5. HiFiMan Edition XS
Driver: planar-magnetic (stealth magnet) | Price: ~$420 | Impedance: 18Ω | Best for: spacious planar sound
The Edition XS takes HiFiMan's larger Stealth Magnet planar driver and packages it in a more affordable shell. The result is a wide, open presentation with the airy staging that planar fans love, plus a touch more bass warmth than the Sundara.
At roughly $420 and only 18Ω, it is easier to drive than many planars, though a quality amp still tightens the bass and improves control. It is a frequent recommendation for listeners who want a big, room-filling sound without flagship money.
Pros:
- Large, spacious soundstage for the price
- Smooth treble that resists fatigue
- Easier to drive than most planars
- Engaging, slightly warm tonality
Cons:
- Big earcups can be awkward on small heads
- Bass tightens up only with a good amp
Verdict: A wide-staging planar bargain that punches into much pricier territory.
6. Beyerdynamic DT 1990 Pro
Driver: 45mm Tesla dynamic | Price: ~$550 | Impedance: 250Ω | Best for: studio detail, mixing
The DT 1990 Pro is a studio reference that audiophiles adopted for its surgical detail. Its 45mm Tesla neodymium driver and two included earpad sets let you tune between an analytical and a balanced response, making it a favorite for mixing and critical work.
At 250Ω it needs amplification, and its treble is famously energetic — revealing on great recordings, a little sharp on poor ones. For listeners who want to hear exactly what is in a track, few things at $550 are more honest.
Pros:
- Razor-sharp detail and transient attack
- Two earpad voicings included in the box
- Tank-like build with replaceable parts
- Genuinely useful for studio mixing
Cons:
- Treble can be sharp on bright recordings
- Demands a capable amp at 250Ω
Verdict: A detail-obsessed studio reference that doubles as an analytical audiophile tool.
7. Audeze LCD-X
Driver: 106mm planar-magnetic | Price: ~$1,199 | Impedance: 20Ω | Best for: bass slam, mastering
The LCD-X is Audeze's pro-leaning flagship and a benchmark for planar bass. Its huge 106mm diaphragm moves air with a physicality dynamic headphones struggle to match, delivering deep, textured low end with zero bloat — a reason it shows up in mastering studios.
At 20Ω it is electrically easy to drive, but it is power-hungry and heavy, so a current-capable amp and a forgiving neck are both recommended. The reward is a weighty, resolving sound with the kind of authority bass-forward listeners crave.
Pros:
- Deep, fast, textured planar bass
- Excellent resolution and macro-dynamics
- Studio-proven for mastering work
- Robust, serviceable construction
Cons:
- Heavy; comfort suffers over long sessions
- Wants current despite low impedance
Verdict: The pick for listeners who want planar slam and mastering-grade resolution.
8. Focal Clear MG
Driver: 40mm aluminum-magnesium dynamic | Price: ~$1,499 | Impedance: 55Ω | Best for: dynamics without an amp tower
The Clear MG is where dynamic-driver technology hits its practical peak. Focal's French-engineered aluminum-magnesium dome trades blows with planars on transient speed, low distortion, and bass control, while keeping the lively, energetic character dynamics do best.
Crucially, at 55Ω and 104dB sensitivity it is the easiest flagship here to drive — a good portable source gets you most of the way, and a desktop amp reveals the rest. For listeners who want near-end-game sound without a stack of gear, it is uniquely convenient.
Pros:
- Fast, dynamic, low-distortion sound
- Easy to drive for a flagship
- Lush microfiber comfort and premium build
- Excellent tonal balance across genres
Cons:
- Soundstage is narrower than the HD 800S
- Premium price for a dynamic driver
Verdict: The most amp-friendly near-flagship — dynamic excellence without the gear pile.
9. Beyerdynamic DT 900 Pro X
Driver: 45mm STELLAR.45 dynamic | Price: ~$299 | Impedance: 48Ω | Best for: easy-drive studio neutral
The DT 900 Pro X modernizes Beyerdynamic's studio formula with the new STELLAR.45 driver and a low 48Ω impedance, so it runs cleanly off phones, laptops, and interfaces without an external amp. Its wide 5–40,000Hz response and detachable cables make it a practical everyday open-back.
The tuning is more balanced and less peaky than the DT 1990 Pro, trading some surgical detail for comfort and ease of use. At around $299 it is a sensible studio-leaning pick for listeners who do not want to buy an amplifier.
Pros:
- Easy to drive at 48Ω — no amp required
- Balanced, fatigue-free tuning
- Detachable cables on both sides
- Comfortable for long sessions
Cons:
- Less resolving than pricier studio cans
- Bass is accurate rather than impactful
Verdict: The no-amp-needed studio open-back for plug-and-play neutral sound.
10. Grado SR325x
Driver: 44mm dynamic | Price: ~$295 | Impedance: 38Ω | Best for: rock, energetic guitar music
The SR325x is Grado's hand-built Brooklyn classic, and it sounds nothing like the smooth Sennheisers. Its forward, energetic presentation puts electric guitars, drums, and vocals right in front of you with a punch that makes rock, blues, and classic recordings come alive.
At 38Ω it drives easily off almost anything, and the metal housing adds a touch of body to the lively tuning. The retro foam-pad ergonomics are polarizing and isolation is essentially nil, but for the right genres nothing this side of $300 is more fun.
Pros:
- Exciting, forward, toe-tapping presentation
- Drives easily off any source
- Hand-assembled in Brooklyn with metal housings
- Outstanding for rock and guitar-driven music
Cons:
- Foam pads and on-ear fit divide opinion
- Bright tuning is not for everyone
Verdict: The fun, energetic pick for rock fans who want excitement over neutrality.
Frequently Asked Questions
Do open-back headphones really need an amplifier? It depends on the model. High-impedance dynamics like the Sennheiser HD 800S, HD 660S2, and HD 600 (all 300Ω) and the Beyerdynamic DT 1990 Pro (250Ω) genuinely need a desktop amp. Easier-to-drive options like the Focal Clear MG (55Ω), DT 900 Pro X (48Ω), and Grado SR325x (38Ω) run well off a phone, laptop, or interface.
Low-impedance planars like the Sundara and LCD-X still want a current-capable amp despite their low ohm ratings.
Why do open-back headphones leak sound? The driver's rear is open to the air, which removes internal resonance and creates the wide, speaker-like soundstage audiophiles want. The cost is that sound escapes outward and outside noise gets in, so open-backs are best in a quiet room and unsuitable for offices, planes, or transit.
What is the difference between dynamic and planar-magnetic drivers? Dynamic drivers (HD 800S, HD 600, Clear MG, Grado) use a voice coil and cone, giving lively dynamics and easy drivability. Planar-magnetic drivers (Sundara, Edition XS, LCD-X) use a thin film suspended in a magnet array, producing fast transients, low distortion, and tight bass, usually at the cost of needing more power.
Which of these is best for gaming or movies? The wide soundstage of the Sennheiser HD 800S and HiFiMan Edition XS gives excellent positional imaging for games and films. If you lack an amp, the easy-to-drive Focal Clear MG or DT 900 Pro X are strong picks.
Is the HD 660S2 worth it over the older HD 650? For most buyers, yes. The HD 660S2 keeps the celebrated 650 midrange while adding real sub-bass extension down to 27.5Hz and a slightly cleaner top end. Choose the HD 650 only if you specifically want its warmer, more relaxed voicing.
Are any of these closed-back? No. Every headphone on this list is an open-back design, which is why they share the airy soundstage and zero-isolation characteristics described throughout.
