Detailed Comparison
Sound Quality
Audio-Technica ATH-ADX3000
The ADX3000 is built around a 58mm dynamic driver and tuned bright and detail-forward. Reviewers consistently praise its resolution, clarity and dynamic punch, but the lively treble — with a sharp peak near 4 kHz — divides opinion, and sub-bass rolls off for those who want low-end slam.
Delivers resolution, clarity and technical performance that reviewers say is incredible for the price — the only dynamic-driver headphone in this range that can go toe-to-toe with pricier planars like the HiFiMan Arya Organic.
Tuned bright and hyper-focused with an emphasis on the upper mids and lower treble — human voices, violins, pianos and acoustic guitars sound more lifelike, though the treble peak makes the overall tonal balance a little wonky.
There is a sharp peak right around 4 kHz; on a 10-band EQ you can pick the 4 kHz band and drop it by 4-5 dB to tame the brightness as a starting point.

Bright, treble-forward tuning with a sharp peak near 4 kHz that can sound harsh or fatiguing, especially for treble-sensitive listeners
Sub-bass rolls off below roughly 50-60 Hz — bass-focused listeners will find it lacks visceral low-end slam without EQ
Purely passive and wired — no Bluetooth, no ANC, no microphone and no battery, so it is unsuitable for commuting, calls or travel
Uses a proprietary A2DC connector and ships with a mediocre stock cable, so cable upgrades mean buying into a less-common termination
Bose QuietComfort Ultra Headphones (2nd Gen)
What Reviewers Agree On
Class-leading active noise cancellation that blocks travel and office noise as well as anything on the market — Bose stays top of the tree alongside Sony
Genuinely all-day comfort: a light ~262g build, soft glasses-friendly pads and low clamping force make multi-hour and full-workday wear painless
Battery is meaningfully improved over Gen 1 — up to 30 hours rated with ANC on (27-28h measured) and a brand-new ANC-off mode that stretches to 45 hours
USB-C lossless wired audio is a real, welcome new capability, and all of Bose's DSP — EQ, ANC, immersive audio — keeps working when wired
Custom-tuned sound is the best Bose has shipped on a headphone: more balanced and less boomy than the bass-heavy Gen 1, with an expansive presentation
Compact fold-flat design and slim hard case make it one of the most travel-friendly flagship ANC headphones
Deal Breakers
An iterative refresh at an unchanged $449 — same design, case, controls and dimensions as Gen 1, so existing owners get little reason to upgrade
No automatic conversation-detect / Speak-to-Chat equivalent — you must manually press a button to drop into Aware mode, a feature gap reviewers and owners call a dealbreaker against Sony
Battery still trails the best rivals — the Sony WH-1000XM6 outlasts it by roughly 10 hours in standardized testing, and far cheaper headphones beat it outright
The companion app gives only a generic three-band (bass/mid/treble) EQ, and the Bose app is widely seen as behind Sony's on software polish
A mid-life over-the-air firmware update removed or changed functionality, frustrating some early owners and denting trust

Bass extends down with a W-shaped lift around 100 Hz and the sub-bass is described as quite nice, but it is not as visceral or punchy as the pricier ADX7000 or Caldera Open.
Bass distortion was not something this reviewer could provoke even as a bass-heavy listener — the driver stays clean under pressure.
Soundstage is open and airy with good left-to-right separation, but it does not feel huge — instruments revolve around you rather than spreading out wide, and it does not match the Focal Utopia.
The relaxed mid-range followed by a more forward treble makes the presentation clinical and superb for detail retrieval, but that treble energy can become fatiguing over long sessions depending on how you listen.
Treble-sensitive listeners report the top end is spicy and present, with clarity and extension — noticeable but not enough to cause ear discomfort the way some bright headphones do.
Reviewers report the drivers benefit from roughly 100 hours of mechanical break-in, after which the treble peak and midrange prominence chill out and more sub-bass impact comes through.
Bose QuietComfort Ultra Headphones (2nd Gen)
Bose's CustomTune snapshots your ear anatomy and compensates the sound to it, and Gen 2 adds a more balanced, less bass-heavy tuning plus a custom three-band EQ. Most reviewers call it the best-sounding Bose headphone yet, though the stock tune still leans bass-forward and a three-band EQ limits how far you can refine it.
This is the best sound presentation reviewers have heard from a Bose headphone — Gen 2's tuning is more refined than the first generation, especially in the highs.
Versus Gen 1, the second gen plays the whole frequency range — bass, mids and treble — nicely together; the original emphasised bass much more, almost up to 15 dB around 30 Hz in the sub-bass.
CustomTune works by snapshotting your ear's response and then compensating for it — and for the best sound quality you need ANC or noise-control mode turned on, since the tuning relies on it.
The stock tune is bass-heavy and best treated like a store-demo mode — it sounds best with some of that bass dialed back in the EQ.
Out of the box you must apply EQ to get the maximum sound quality — but once tuned, Gen 2 is a very enjoyable and balanced listen with very few weaknesses.
Bose still only provides a generic three-band custom equalizer with bass, middle and treble sliders — fine-grained tuning means relying on third-party EQ apps.
The Gen 2 trades a little of the original's raw loudness for a more detailed, refined sound — a tradeoff worth taking over the louder, boomier Gen 1.
Reddit owners praise the sound: the ANC is so effective you don't need to crank the volume to enjoy the full sound.
Comfort & Design
Audio-Technica ATH-ADX3000
The ADX3000's headline trait is its weight — around 257g makes it one of the lightest premium open-backs available. A 3D wing-support headband, plush velour pads and a low-but-firm initial clamp combine into a fit reviewers say quickly disappears.
Crazy light at 257g — a paperweight compared with most headphones in its class — and that lightness is a major comfort advantage for long sessions.
Audio-Technica navigated the usual lightweight trade-off well — it stays very lightweight and comfortable yet still feels and looks extremely premium.
The 3D wing-support system plus plush velour pads mean the padding mostly touches the skull rather than clamping, which helps avoid headphone fatigue and makes it easy to forget the headphones are on.
Measured clamp force is around 600-750g — it can feel a little firm the moment you put it on, but the combination of weight, soft pads and clamp means it very quickly becomes one of the least intrusive headphones this reviewer has worn.
One reviewer found this the least comfortable of the headphones in a comparison group, a reminder that fit is head-shape dependent despite the low weight.
Build quality is high-end — reviewers describe super high-end quality and build, with a simple black open-back-with-mesh-grille aesthetic rather than flashy luxury materials.
Left/right channel markings on the cups are small and easy to miss, and the stock cable carries no side marking — a minor everyday annoyance.
Bose QuietComfort Ultra Headphones (2nd Gen)
Comfort is a near-universal win — a light ~262g build, soft glasses-friendly pads and low clamping force make these one of the easiest flagship ANC headphones to wear all day. The design, dimensions and case are carried over unchanged from Gen 1, with only updated leather-style materials and a slightly more premium feel.
After two months of daily use these are the best-feeling headphones the reviewer owns — wearable for very long stretches where many headphones get uncomfortable after two hours.
The headphones weigh in at 262g — lightweight for a pair of premium ANC over-ears, where rivals often sit between 280 and 300g.
Around 260g with a soft-padded headband, the ear cups fold inward on a proper hinge and drop into a hard-shell carry case with a magnetic clasp.
The ear cups fold in, making the case significantly more compact than much of the competition — a real win for regular travellers.
Bose has stepped up the build with aluminium elements and sturdier plastics while keeping the headphones light — a long-standing critique partially addressed.
Value vs Competition
Audio-Technica ATH-ADX3000
At $999, the ADX3000 is positioned against planar open-backs and Audio-Technica's own pricier ADX5000 and ADX7000. Reviewers broadly call it strong value for a buyer who wants technical performance, with the ADX3000-vs-ADX5000 question coming down to tuning preference.
Retails for $999 as an open-back single-driver headphone — reviewers call it a very good entryway into high-end headphones and could not find much wrong at the price.
Offers HiFiMan-style clarity and resolution combined with good dynamic punch, incredible build quality and very low weight — a combination reviewers say is hard to beat in this price bracket.
Versus the pricier ADX5000: some reviewers say the significantly cheaper ADX3000 actually has the better tuning, while others give the ADX5000 a higher-end feel and a slightly wider horizontal sound field.
For the price point it is a solid, near-the-top performer for accurate, lifelike balance between fundamentals and harmonics — though one reviewer stops short of calling it class-leading.
Buyers on a tighter budget who still want the Audio-Technica house sound can consider the much cheaper ATH-R50x or ATH-R70x, which are easier to drive and a fraction of the price.
Reddit owners frame the ADX3000 as a fun, clear, open headphone with a nice treble pop and consider it a worthwhile plunge for listeners coming from mid-tier sets like the Beyerdynamic DT1990.
Bose QuietComfort Ultra Headphones (2nd Gen)
At an unchanged $449 the QC Ultra 2 sits head-to-head with the Sony WH-1000XM6 and AirPods Max. It wins on ANC and comfort and undercuts the AirPods Max, but trails Sony on battery and software — and with the near-identical Gen 1 now heavily discounted, the value case depends heavily on how much you weigh the new battery, USB-C audio and refined sound.
Forbes tested more than 25 pairs and named the Bose QuietComfort Ultra Headphones (2nd Gen) the best wireless headphones overall.
Gen 2 launches at $449 in both the US and UK — exactly the same as Gen 1's launch price, a small step up from the older $429 QC Ultra.
Against the AirPods Max 2 the Bose gives 30 hours of battery to Apple's 20, weighs about 120g less and costs $100 less — the more practical daily driver.
Versus the Sony WH-1000XM6 it's a genuinely close call — Bose wins comfort and ties on ANC, but Sony pulls ahead on battery life and the depth of its app and automation.
This is an iterative refresh: the dimensions, case and controls are identical to Gen 1, with the changes limited to a slightly different leather-style material and what Bose calls an updated design.
RecordingNOW measured Gen 2 at 262g, around 8g heavier than the Gen 1 it tested — still light, but not a weight reduction.
Reddit owners back up the comfort: they fit super nicely and are really light, with leather and build quality that feel top-notch and premium.
The pads do not have the thickest foam, so passive (ANC-off) noise blocking isn't class-leading, and warm weather can mean airing the cups out occasionally.
Because Gen 1 is roughly 90% the same headphone and now sees steep discounts (as low as $299 on Black Friday), a discounted original can be the smarter buy for value hunters.
A reviewer writing an ANC buying guide rated a rival as the headphone to get — yet still found the QC Ultra more impressive in certain ways, making it a difficult choice at this price.
For travel and desk work the QC Ultra 2 is reviewers' clear pick — the comfort, ANC and battery make them the headphones owners reach for all the time.
