Compare Bose QuietComfort Ultra Earbuds (2nd Gen) vs Bose QuietComfort Ultra Bluetooth Headphones (2nd Gen)

Analog input is useful and dedicated, though one reviewer notes the headphone-side cable connection is less common.

Reviewers strongly agree that ANC is the standout feature: it removes airplane, subway, traffic, keyboard, cafe, and other ambient noise better than most or all earbuds they tested, with only minor caveats about hiss or sudden spikes.

Active noise cancellation is the product’s strongest consensus win, repeatedly described as elite, best-in-class, or among the best available.

Advanced software features are mixed: CustomTune and acoustic compensation impress some reviewers, while others complain that Bose offers little new.

The profile is seen as discreet and attractive, with reviewers saying the headphones look good without standing out too much.

ANC background noise is generally improved or very low, with reviewers praising quiet operation and reduced hiss, though not every review is flawless.

ANC-off mode is a sonic caveat because one reviewer says tonality worsens with ANC disabled.

ANC is praised for not changing the headphone’s sonic character in one review’s listening.

Android users are treated as a strong audience because the earbuds support advanced options and Snapdragon-related features, though some phone compatibility limits remain.

Android compatibility is positive where reviewers mention Google Fast Pair and Snapdragon/aptX Adaptive support.

The Bose app is useful and sometimes clean, offering modes, controls, sources, EQ, and fit tools, but reviewers also found it mandatory, occasionally daunting, and not especially customizable.

The app is generally easy to use, but reviewers often describe it as limited, basic, or not as feature-rich as rivals.

aptX Lossless/Snapdragon Sound support is viewed as a useful premium codec feature for compatible devices.

aptX support is treated as a meaningful upside for compatible newer Android devices, even though the transcript renders it as AEX.

Audio-video sync is praised for video editing, but gaming latency is criticized for quick-reaction games, making latency performance mixed by use case.

Wired USB-C listening is credited with reducing Bluetooth latency, giving it a practical audio-video sync benefit.

Wear detection for wake/play behavior is praised for quickly waking and connecting when the headphones are put on.

Auto on/off behavior is praised for quick wake, sleep, and battery-saving reliability.

Award recognition is strong in the RecordingNow review, which gives the headphones an Editor’s Choice-style recognition.

Bass is generally rich, punchy, and deep, but some reviewers think Bose overboosts the low end or gives it too much emphasis for neutral listening.

Bass is frequently praised as strong, deep, and enjoyable, though a few reviewers call the default balance bass-heavy or V-shaped.

Battery life is consistently described as adequate or average rather than class-leading, usually around six hours with ANC and less with immersive audio.

Battery life is improved and usually adequate, but reviewers commonly frame it as average, mid-pack, or not class-leading.

Bluetooth reliability is mostly positive, with several reviewers reporting no dropouts, though one reviewer wished Bose had moved beyond Bluetooth 5.3.

Bluetooth pairing is described as straightforward, supporting an easy day-to-day connection experience.

Bluetooth 5.4 is viewed mildly positively as a useful modern update rather than a major advantage.

Build quality is described as premium for the earbuds themselves, even when the case does not always feel equally high-end.

Build quality is acceptable to good, but reviewers split between reassuring solidity and complaints about plasticky or less premium feel.

The built-in DAC/USB-C hi-res path is repeatedly praised for clearer, more detailed, or higher-quality wired playback.

For running, one reviewer would prefer physical button controls because touch gestures are harder to use precisely during workouts.

Button usability is mixed, with some reviewers liking the balance of buttons and touch and others criticizing overloaded controls.

The included cable drew a minor complaint because PCMag wanted a longer USB-C-to-USB-C cable.

The case is functional and now charges wirelessly, but reviewers repeatedly describe it as bulky, clunky, or less premium than the earbuds.

The carry case is usually praised as compact, protective, or sturdy, though a few reviewers find the fit awkward or the zip case less convenient.

Charging is a notable upgrade thanks to wireless charging and case improvements, although one running-focused review found quick charging slower than ideal.

Charging gets positive evidence from the quick-charge result and ability to recover several hours quickly.

Clamping force is usually praised as gentle or well judged, though one reviewer found the fit snug.

Codec support is praised as premium because the earbuds support high-quality Bluetooth codecs.

Codec support is viewed positively where aptX Adaptive/Snapdragon Sound support is relevant, especially for compatible Android devices.

Comfort is a major strength for many reviewers over long sessions, flights, runs, and daily use, though very small ears may struggle.

Comfort during long use is one of the most consistent strengths, with reviewers repeatedly saying the headphones can be worn for hours.

Connectivity options are a strength because reviewers say USB-C, analog, and Bluetooth make it hard to be stuck without a usable connection.

Design impressions are mixed-positive: some like the sleek, subtle, creative look, while others note the chunky or busy shape may divide people.

Design feedback is generally positive, with reviewers liking the modern look, finish options, and refined styling.

The lack of a low-latency dongle is a drawback when compared with more flexible rivals.

Durability evidence is positive but limited, mostly based on case wear and confidence in long-term construction.

Earcup padding is strongly praised as plush, cushy, soft, and supportive.

Several runners or active users noticed footstep thud or earbud movement noise, especially during runs or with sweaty ears.

Fit is generally secure and seal-friendly, helped by the ovoid nozzle, ear tips, and stability bands, though individual ear shape still matters.

Ear tip and wing options help fit, but the running-focused review wanted more than three sizes at this price.

EQ customization is the clearest software weakness: many reviewers criticize the basic three-band EQ as too limited for premium earbuds.

EQ customization is one of the most repeated complaints because Bose still relies on a simple three-band EQ.

Measurement-focused reviews say the frequency response is heavily shaped, with overemphasized bass and treble and recessed mids.

Frequency balance is debated: some reviewers hear an impressively balanced profile after EQ, while others find the default tuning bassy, safe, or not neutral.

Headband padding is praised as soft and supportive, helping the headphones stay comfortable for long sessions.

The hinge and moving hardware are described positively because the moving parts use high-quality metal.

Immersive audio quality is highly split, with some reviewers loving cinema/spatial effects and others preferring normal stereo.

Included fit accessories are appreciated when they help tailor the fit, though other reviews still wanted more size options.

Included accessories are appreciated, especially the case plus charging and audio cables.

Instrument separation is widely praised, with reviewers hearing open mixes, distinct sections, and easy-to-pick-out track elements.

Instrument separation is usually seen as good to excellent, though one reviewer notes it can struggle when mixes get busy.

Integrated microphones are praised in stronger call-focused reviews for clear voice pickup and background rejection.

The integrated microphone is serviceable to good, with clear call presence, though not always exceptional.

LE Audio readiness is weak because one reviewer specifically complains that low-energy goodies are still missing.

Lossless support through aptX Lossless/Snapdragon Sound is treated as a useful premium feature for compatible devices.

Maximum-volume clarity is strong in the running review, which heard clarity and no distortion even when volume was raised.

Reviewers note that fine detail and micro-detail are not class-leading, even when the overall sound is enjoyable.

Microphone noise reduction ranges from excellent SpeechClarity performance to weaker lab samples, but the overall reviewer consensus is improved and often strong.

Microphone noise handling is generally positive, with reviewers saying voices stay clear and background noise is reduced well in common noisy settings.

Call microphone quality is mixed: some reviewers call it exceptional or much improved, while others say it is merely fine or still affected by noise.

Call microphone quality is usually good enough to excellent, but not every reviewer finds it full-bodied or exceptional.

Midrange clarity is usually praised for warm vocals or crisp presentation, but measurement-focused reviewers complain that boosted lows and highs recess the mids.

Midrange feedback is mixed: several reviewers like vocal clarity and texture, while others hear recessed or dull low mids.

Cross-platform use is positive, with reviewers recommending Bose for both Android and iPhone users and reporting smooth use on both platforms.

Multi-platform compatibility is a strength, especially for users switching across phones, laptops, Android, iOS, and other operating systems.

Multipoint is a welcome and often seamless upgrade, though one reviewer noted setup/custom tune trouble when audio was already playing.

Multipoint is a clear strength in the reviews, with seamless switching and reliable two-device behavior praised repeatedly.

Passive isolation benefits from a tight seal and secure nozzle shape, with reviewers noting strong sealing and little noise bleed.

Passive isolation is considered useful and fairly good, but one reviewer notes the foam is not the thickest.

Overall recommendations are positive for new buyers and travel users, but several reviewers temper that with Gen 1 upgrade and price caveats.

Portability is mixed because the earbuds and case are pocketable, but the case is often called large or hard to carry while running.

Portability is a strength because reviewers like the foldable frame and compact travel form.

Premium feel is mixed: the Gen 2 can feel nicer than before, but multiple reviewers still call out plastic, rattling, or non-premium materials.

Preset EQ profiles are poorly regarded because they are basic and do not adequately fix the tuning complaints.

Preset EQ quality is weak in the evidence, with reviewers calling presets ineffective or lackluster.

Replaceable earpads are a practical upside for cleaning, wear, and possible third-party pad swaps.

Sensor behavior is a weak spot in the few comments available, with reviewers criticizing early CustomTune firing and suggesting in-ear detection be disabled.

Smart listening features such as ActiveSense and immersive audio are appreciated when they solve practical problems, but the enthusiasm is not universal.

Smart Pause works but has a caveat: folding the headphones can defeat the lay-flat pause behavior and waste battery.

Smudge resistance is a downside because glossy accents pick up fingerprints and dust.

Setup simplicity is imperfect because one reviewer reported trouble with CustomTune when connecting another device during playback.

Setup and navigation are generally easy, with reviewers praising stability, intuitive menus, and simple access to features.

Sound leakage is rated positively in the one direct test, with the reviewer reporting little outside noise bleed.

Sound quality is broadly strong, with rich, detailed, bass-forward playback praised by most reviewers, though a few disliked the stock tuning.

Reviews are broadly positive on sound quality, especially after EQ or over USB-C, but several reviewers still found the tuning less refined than top sonic rivals.

Soundstage depth is praised in orchestral and spacious listening comments, though evidence is less extensive than for overall sound quality.

Soundstage width is praised for an open, wide, detailed presentation that helps mixes feel bigger than typical earbuds.

Reviewers often describe the soundstage as wide, spacious, or open, especially for closed-back ANC headphones.

Spatial audio is divisive: some reviewers find it natural, cool, or useful, while others prefer standard stereo or dislike the processing.

Spatial and cinema modes are divisive: movie use receives praise, while music-focused immersive modes are less consistently liked.

Stability is mostly excellent, especially for running and workouts, but one reviewer still disliked the running feel and movement.

Stability is adequate for light movement, but not ideal for dynamic workouts or smaller heads.

Streaming integration is a limitation because the app lacks built-in music service or internet radio integration.

Touch controls split reviewers: some find them responsive, intuitive, and complete, while others call them fussy or hard to use precisely during runs.

Touch control feedback is mixed: some reviewers find the slider responsive, while others call it imprecise or annoying.

Transparency mode is generally good to excellent, especially Aware/ActiveSense, but several reviewers still prefer Apple or note wind, hiss, or manual-adjustment limits.

Transparency mode is generally praised as natural and useful, though several reviewers note hiss, reduced level, or weaker performance than AirPods Max or Sony.

Travel friendliness is a major strength because reviewers highlight comfort, ANC, foldability, and long-flight usefulness.

Treble is often described as clear, sparkly, or balanced, but measurement-focused reviews say it can be overemphasized or occasionally hard to fix with EQ.

Treble is generally smooth or crisp enough, but reviewers do not treat it as the strongest part of the tuning.

USB-C audio is one of the clearest feature upgrades, praised for lossless listening and practical wired use.

Value depends heavily on priorities: reviewers see the premium price as justified for ANC and sound, but weak for Gen 1 owners or bargain-focused buyers.

Value is mixed: reviewers like the feature set and experience, but price and weak upgrade logic for Gen 1 owners are repeated caveats.

Voice assistant integration gets limited but positive evidence, with reviewers saying Google Assistant or assistant shortcuts worked without hassle.

Volume output is strong in the one direct measurement-style review, which says Bose makes loud earbuds.

USB-C playback is praised for giving more output headroom for listeners who want louder playback.

Water and sweat resistance is considered sufficient for workouts and light rain, though not fully waterproof.

Water and sweat resistance is a weakness because reviewers call out the lack of an ingress protection rating.

Auto-pause is generally positive, with reviewers noting automatic pause and power-up behavior when the headphones are removed or worn.

Wear detection performance is praised as excellent in daily use.

Weight comfort is positive despite the buds being chunky or slightly heavier; reviewers said the weight was not annoying and still felt fine.

Reviewers repeatedly connect the low weight to comfort, calling the headphones light and easy to wear.
