Compare Bose QuietComfort Ultra Bluetooth Headphones (2nd Gen) vs Sennheiser MOMENTUM 4 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 effectiveness is mixed across sources: some call it very good and close to leaders, while others measure it as clearly behind top Bose and Sony options, especially for tougher noise scenarios. ANC adjustability is widely praised thanks to sliders, adaptive behavior, and app-driven profiles and zones that let you tune isolation versus awareness.

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

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 Smart Control app is widely viewed as feature-rich with EQ and zone-based behavior, but some reviewers dislike setup friction, pop-ups, or account requirements for certain features.

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 is a notable plus cited by several reviews, helping Android users with more consistent performance compared to AAC in many setups.

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.

Audio-video sync is generally reported as strong for video watching, with latency management helped by codec selection in some advice-focused reviews.

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 commonly described as elevated and impactful without constant bleed, but several reviewers note it can be a bit much stock and may benefit from EQ to reduce boom or flab in some tracks.

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 the most consistent standout: multiple sources cite roughly 50 to 60 hours or more with ANC depending on test methods and usage.

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 generally solid with modern connectivity, though real-world reliability can still depend on device ecosystem and nearby previously paired devices.

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 typically seen as solid but more plastic-heavy and less premium-feeling than metal-rich rivals; durability is considered fine with reasonable care.

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

The single physical power and pairing control is sometimes criticized as finicky or confusing compared to simpler button-driven systems.

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.

One review criticizes the included analog cable as thin and less confidence-inspiring for travel wear and tear.

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 usually praised as protective with storage for cables, but a few reviews call it larger than ideal for pack-light travel.

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 is generally strong, with quick-charge claims and reasonable full-charge times; experiences vary slightly by power source and usage.

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.

Clamp force is often described as moderate and comfortable, but the lighter clamp can trade off with stability during movement-heavy activities.

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 strong for mainstream and Android use, including multiple aptX options and AAC, but it is not positioned around newer lossless Bluetooth standards.

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.

Comfort is frequently described as excellent, including long sessions and glasses-friendly padding, though a few users report headband pressure or fit quirks during extreme-length wear.

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 commonly described as minimalist and understated; some like the clean look while others miss the more distinctive style of earlier Momentum models.

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.

Earpads are commonly described as soft and comfortable, contributing to long-wear comfort; the softer seal may slightly reduce isolation for some.

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

Earcup rotation is praised in at least one review as smooth and helpful for fit, with cups lying flat for storage and neck rest.

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 customization is a meaningful strength across reviews, commonly used to tame bass, refine mids, or personalize the overall signature without major distortion issues.

Find My style tracking is described as lacking compared to Apple ecosystem features in at least one review.

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.

Measurements and listening impressions generally align on a well-tuned response for broad appeal, with small deviations (notably bass lift) that can be refined via EQ.

Fit and adjustability are generally straightforward, though users are advised not to over-tighten because pressure points can develop.

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

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

Accessories are generally generous, commonly including a case, charging cable, analog cable, and an airplane adapter, though one review notes a missing adapter compared to the prior generation.

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

Instrument separation and imaging are commonly rated as strong for the category, with clear placement and good stereo definition, though not always a large leap over prior models.

LDAC is not supported and is repeatedly mentioned as the key wireless hi-res omission for enthusiasts.

Even when pushed loud, multiple reviews note the sound stays clean, but the practical ceiling can feel lower than expected compared to peers.

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 rejection for calls is a frequent criticism, with several reviews noting background sounds can intrude; wind reduction features can help in some cases.

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 quality trends average-to-good in quiet rooms, but multiple tests report reduced clarity and competitiveness when background noise is present.

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 is generally clear, but some reviews call it less rich than Momentum 3 or slightly recessed depending on tuning, with vocals still remaining clean and present for most listeners.

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

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 is supported and often convenient, but at least one lab test reports occasional glitches when other known devices are nearby, even though switching can be quick once connected.

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 is a recurring weak point in several lab-style reviews, sometimes attributed to a softer seal; others find it adequate in real travel use.

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

Portability is good but not best-in-class: cups lie flat and cases can be compact versus some rivals, yet the design does not fully fold into the headband in some reports.

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 modes and guided personalization features are generally useful and can improve tonality for specific tastes, though some presets may limit manual slider control.

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

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

Wear sensors and auto pause features are frequently mentioned as useful quality-of-life additions, though auto power behaviors can be inconsistent for some users.

Sidetone is praised in at least one review for making calls feel more natural by letting you hear your own voice more clearly.

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

Surface smudging is mentioned as manageable: oils can show with regular handling but a quick wipe restores a clean look.

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

Setup and daily control are generally easy once configured, but a few reviewers report initial friction in the app experience or connection steps.

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.

Sound quality is a consistent highlight: most reviews describe an engaging, detailed presentation that competes strongly at the price, often with a fun, slightly bass-forward tilt and strong clarity after light EQ if desired. Wired audio can sound tighter and more stable than Bluetooth in some reports, but at least one review warns wired listening can degrade significantly if the headphones are not powered on.

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

Soundstage is usually described as wide enough for an immersive feel, but depth can be limited and some tests describe the stage as more inside-the-cups than truly expansive.

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.

Spatial audio support is not a core strength in these reviews, with some calling it limited or weaker than ecosystem-driven alternatives.

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.

Fit stability can be a weakness during vigorous movement due to moderate clamping, with at least one test noting issues beyond walking.

Sustainability gets a small nod through minimalist, paper-forward packaging in at least one review, though it is not a dominant theme.

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 often described as intuitive and capable, but several reviews mention sensitivity, accidental triggers, or occasional glitches requiring app toggles.

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 is adjustable and generally usable, but opinions vary: some like the control and naturalness, while others find it less crisp or overly amplified in busy spaces.

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 frequently praised for detail and shimmer, though a few reviewers mention occasional brightness, fatigue, or a sharper peak that may bother treble-sensitive listeners.

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 a key advantage: reviews highlight charging convenience and USB-C audio as a rare, practical feature for wired 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 output is sometimes reported as lower than competing flagships, leading some users to run near the top of the volume range.

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

Water resistance is effectively absent in practice: at least one review notes no IP rating and recommends avoiding rain.

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

Weight is typically reported around the 290g range and perceived as manageable, though not the lightest in class and still a factor for ultra-long sessions for some users.
