Compare Bose QuietComfort Ultra Bluetooth Headphones (2nd Gen) vs Beyerdynamic Aventho 300 Wireless Headphones

Noise cancelation is consistently described as top-tier and often best-in-class, with Gen 2 seen as a small refinement (more precise, fewer quirks); some outlets still give Sony a slight edge in ultimate silence. Most reviews highlight easy ANC control through modes or a slider (often 1–10) and note Gen 2 can fully disable ANC, which improves flexibility and battery options.

ANC performance ranges from decent to underwhelming for the price; it tends to handle low-frequency rumble better than mid and high-frequency noise, and trails class leaders. ANC settings are flexible, with multiple strength levels (and an adaptive mode) available via the app and on-headphone controls.

Android support is repeatedly described as strong, with easy pairing and the best codec features (aptX family) available on compatible Snapdragon phones.

Android use is generally smooth, with modern codecs and stable pairing frequently mentioned as benefits for Android users.

The companion app is generally stable and straightforward for modes, ANC, immersive audio, and device management, but many reviewers describe it as basic compared with feature-rich competitors.

The companion app is typically seen as clean and easy to navigate, though not feature-rich compared with the very best ecosystems.

Reviews that discuss codecs call out aptX Adaptive and related options (including lossless/low-latency variants on compatible Snapdragon devices) as a meaningful plus for Android users.

aptX support (including Lossless/Adaptive) is repeatedly cited as a key advantage, especially for Android and Snapdragon Sound users.

USB-C wired audio is noted to reduce Bluetooth latency by tens of milliseconds, which can improve lip-sync for video compared with wireless use.

Bass is widely praised as deeper, punchier, and more controlled than the prior model, though a couple reviewers still describe it as warm or occasionally one-note depending on genre and settings.

Bass is a defining trait: commonly thick and boosted with good extension, but several reviewers call it boomy or overdone until EQ is applied.

Battery life is commonly reported around 27–30 hours with ANC on, which is competitive but not class-leading; immersive/spatial modes reduce runtime, and some sources note longer life with ANC off.

Battery life is a headline strength: many cite around 50 hours with ANC on, and some tests report substantially higher real-world endurance.

Bluetooth performance is often described as quick to connect and stable in daily use, but a minority report occasional connection quirks or issues.

Bluetooth stability is a strong point in most reviews, with few dropouts reported and Bluetooth 5.4 frequently highlighted.

Build quality is generally seen as durable enough for daily travel, but the heavy use of plastic and occasional rattly feel reduce the perceived premium value at this price.

Build quality is consistently highlighted, with metal components and a sturdy, low-creak feel that compares favorably to many all-plastic competitors.

Physical buttons are serviceable but frequently criticized for doing too many functions (pairing/power, multi-press combos) and offering limited customization.

Physical buttons get mixed feedback: some find them small, mushy, or hard to distinguish by feel, while others report they work fine once learned.

Several reviewers mention the 2.5mm analog input as less common than 3.5mm, but the included cable and USB-C option make it easy to stay connected when needed.

Accessories include both USB-C and 3.5mm cables (plus an adapter in several reviews) and are generally viewed as solid and practical.

The included case is widely appreciated for being sturdy and compact, though some reviewers find the folding orientation awkward or wish the case design were quicker to open/close.

The carry case is frequently praised as premium and protective, and several reviewers like that a soft pouch or dust bag is also included.

Charging is typically described as convenient, with quick-charge figures around 15 minutes for a few hours of playback and full charge around a few hours; USB-C also enables charging while listening.

Charging over USB-C is straightforward, with fast-charge claims around 10 minutes for roughly 5 hours and full-charge times around two hours.

Clamping force is usually described as gentle and fatigue-free, but a few reviewers find the fit on the snug side (great for seal) or potentially too loose for smaller heads during movement.

Clamping force often skews tight, which helps stability and seal but can become fatiguing for larger heads.

Codec support is described as modern and well-rounded for 2025-era ANC headphones, with standard codecs plus aptX Adaptive family and multiple wired options; performance depends on your source device support.

Codec support is a standout, commonly noted for including AAC plus higher-end options like aptX Lossless, aptX Adaptive, and LE Audio.

Comfort is a core strength: many reviewers call it class-leading for long sessions thanks to light weight, plush pads, and an easy seal, with only occasional notes about heat buildup or fit preferences.

Long-session comfort is divisive: some find the fit pleasant, while others report discomfort after an hour or two due to clamp, heat, or ear clearance.

Design is largely unchanged from the previous generation, with updated glossy accents and more color options; reactions range from stylishly understated to a bit boring or too fingerprint-prone.

Design is generally seen as sleek and premium-looking, leaning understated rather than flashy; finish impressions vary from fingerprint-resistant to smudge-prone.

Detachable wired options add flexibility for travel, low-latency use, and compatibility with sources that cannot use Bluetooth.

At least one reviewer notes there is no dedicated low-latency wireless dongle, limiting plug-and-play latency solutions for gaming compared with some rivals.

Earpads are typically described as soft, deep, and comfortable, though some users note ears can touch the inner padding or that the surface may not feel ultra-premium to the touch.

Pads are described as plush by some and stiff or shallow by others; deeper cups help, but heat build-up and ear contact show up in multiple accounts.

The yoke/rotation design allows the cups to lay flat, but at least one review notes the rotation range is limited in one direction.

Cup swivel and articulation are well regarded, allowing the headphones to lay flatter and fit a range of head shapes; a few note minor rocking from pad shape.

EQ control is repeatedly called out as limited (a simple 3-band slider), good for small tweaks but not ideal for listeners who want granular tuning.

EQ options center on a 5-band equalizer and presets; many appreciate the control, but measurement-focused reviewers argue it is not granular enough to correct all issues.

Tonality can be shaped into a more balanced response with CustomTune and light EQ, but out of the box many characterize it as a V-shaped or slightly dark consumer tuning rather than strictly neutral.

Frequency balance is polarizing: some call it even-handed, while measurement-driven reviews point to large deviations (bass and treble boosts and a vocal region dip).

Adjustment mechanisms are generally praised for feeling secure and premium, including ratcheting steps that hold position well.

Where mentioned, the metal headband/hinge structure is viewed as reassuring, even though much of the exterior uses plastic to save weight.

Hinges and joints are widely described as robust, with metal hardware that inspires confidence in long-term durability.

Accessories are typically described as solid for the category, with a sturdy case plus USB-C and analog cables included for flexible connections.

Included accessories are strong for the price, often including a hard case, soft pouch or bag, USB-C cable, USB-A adapter, and a 3.5mm cable.

Instrument separation is rated good-to-excellent, with most reviewers finding layering and placement strong; a few note busy mixes can still blur slightly.

Imaging and separation are consistently strong, helping instruments stay distinct even when the overall frequency balance is debated.

Noise reduction on calls is usually effective, keeping background sounds lower while preserving speech, though some tests still let intermittent noise bleed through or add a slightly processed character.

Noise reduction for the mic is serviceable but not elite; wind and traffic can still be audible unless you speak up.

Call quality is generally good for a premium ANC headphone, with most reviewers saying voices stay intelligible in noisy places; a few describe it as merely fine, compressed, or not exceptional.

Call mic quality is usually fine in quiet conditions, but clarity drops in noisier streets or windy situations compared with the best phone-call headphones.

Midrange is generally clear with solid vocal presence, but some reviews note slightly recessed or less biting mids (especially for guitars/rock) compared with top competitors.

Midrange quality is mixed: some hear warm, impressive mids, while others report recessed vocals or slightly unnatural timbre depending on tracks and tuning.

Cross-platform use is a common strength, with reviewers noting smooth switching between phones and computers across iOS and Android ecosystems.

Multi-device compatibility is a plus, spanning phones and computers and supported by both multipoint Bluetooth and wired inputs.

Multipoint is widely praised as seamless for two devices with smooth switching; a couple edge cases (e.g., juggling TV/phone or certain setups) can be finicky.

Multipoint generally works reliably, but usability varies: some note the app does not show connected devices or make switching as effortless as certain rivals.

Passive isolation benefits from a good seal and deep cups, but a few reviewers note the foam is not the thickest; overall, it helps the ANC work even better on commutes.

Passive isolation benefits from a solid seal, but it does not fully replace top-tier ANC in louder environments.

Portability is strong for a flagship ANC headphone: the frame folds and articulates well, keeping the carry footprint compact for travel.

Most reviews describe foldability that fits the headphones into a protective case, though at least one comparison notes limited folding for ultra-compact packing.

Preset EQ or mode profiles exist and can help (e.g., bass-reducing or treble-boosting options), but many reviewers find the presets and overall EQ ecosystem underwhelming.

Preset profiles like Neutral or Smooth can be genuinely useful for dialing back bass or treble, though some report changes in perceived loudness when toggling EQ.

Replaceable earpads are highlighted as a practical perk for long-term ownership, cleaning, and swapping for third-party pad options.

Replaceable earpads (and sometimes the headband) are called out as a longevity-friendly design choice.

Sensors and automation (on-head detection, auto pause, low-power modes) are often praised for making the headphones feel effortless day to day.

Wear-detection sensors support auto pause and resume; behavior can be a little too eager for some, but the feature set is generally appreciated.

Sidetone is available and adjustable, which can help calls for some users even if others prefer it turned off.

Glossy accents look more premium to some, but multiple reviewers mention they pick up fingerprints and dust more easily than matte finishes.

Smudge resistance depends on finish and handling: some report minimal fingerprints, while others notice visible marks with regular contact.

Setup is generally described as simple, with fast pairing and reliable auto-connect behaviors that reduce daily friction.

Setup is typically painless, with straightforward pairing and a simple app layout; firmware updates are reported as quick and uncomplicated.

Across reviews, the sound is described as enjoyable and travel-friendly, with a consumer-leaning tuning and strong bass; several reviewers say it improves on Gen 1, but a few still find it only fine or a bit dark versus audiophile-leaning rivals. Wired playback (especially over USB-C) is frequently described as clearer or more detailed than Bluetooth, with the bonus of charging-while-listening; analog wired is also supported for older sources.

Reviews disagree on the overall sound: many praise a warm, detailed, spacious presentation, while others criticize the stock tuning as overly colored and not reference-like. Wired listening via 3.5mm and USB-C is a valued feature; some reviewers prefer the USB-C wired mode for extra clarity and dynamics.

Soundstage is repeatedly called wide and open for a closed-back ANC headphone, helping music and movies feel less claustrophobic.

Soundstage is frequently described as wide and immersive, with an enveloping presentation; some report even better clarity and space when listening wired over USB-C.

Immersive/spatial features (including cinema mode) get mixed reactions: some love cinema for clearer dialogue and a bigger movie feel, while others dislike the processing and prefer stereo for music.

Dolby Atmos and head tracking are a major feature: some find the effect subtle and well executed, while others dislike the tonal shift or report jumpy tracking behavior.

Fit stability is good for desk work, commuting, and light movement, but several reviewers caution it is not ideal for more dynamic workouts due to the lack of an IP rating and comfort-first clamping.

The touch volume control is divisive: some find it responsive and sleek, while others call it imprecise or too easy to trigger large volume changes, especially without tactile feedback.

Touch controls are usually accurate and easy to learn, with occasional accidental triggers or misfires while moving or when handling the headphones.

Transparency mode is commonly rated among the best and natural-sounding, though several reviewers mention a faint hiss/white noise or slightly reduced openness versus the very best implementations.

Transparency mode is adjustable and generally useful, though some find the highest setting overly sharp or bright in the upper frequencies.

Treble is typically smooth and cleaner than Gen 1, avoiding harshness; however, multiple reviewers wish for more sparkle or micro-detail and often add treble via EQ.

Treble is generally clear and energetic, but can bring sibilance or harshness for sensitive listeners; a few note slight top-end roll-off or prefer EQ to smooth it.

USB-C is a key Gen 2 upgrade, enabling digital audio input (often described as lossless/hi-res) in addition to charging, and allowing simultaneous charge-and-listen use cases.

USB-C is used for charging and, in several reviews, for wired audio playback, adding versatility beyond standard Bluetooth listening.

Voice assistant access is supported via shortcuts or touch-and-hold actions in the app, making it easy to trigger assistants without pulling out your phone.

Volume output is generally ample, and at least one reviewer reports slightly higher output when using USB-C wired audio.

Volume headroom is ample, with multiple reviewers noting the headphones get very loud without obvious strain at typical listening levels.

Multiple reviews emphasize there is no official water or sweat rating, making these a poor choice for rain, heavy workouts, or sweaty gym sessions.

Weight is repeatedly highlighted as a major comfort advantage versus heavier rivals, making it easier to wear for travel and workdays.

At roughly 319g, weight is noticeable for some listeners and is part of the comfort complaints, though others still consider it manageable.
