Compare Bose QuietComfort Ultra Earbuds (2nd Gen) vs Sennheiser Momentum True Wireless 4 Earbuds

Noise cancelling is repeatedly described as class-leading, with especially strong suppression of engine rumble and broad-spectrum everyday noise; a few reviews note minor hiss or occasional artifacts with sudden loud impacts, but overall performance remains top tier. Adjustability is strong via app modes and sliders, including custom levels and adaptive behavior (such as smoothing spikes), though some mode limitations and UI quirks are mentioned.

ANC performance is widely considered good to very good, especially for steady low-frequency noise (commutes, travel). Multiple sources still rank Sony or Bose as stronger overall, with some higher-frequency or sudden sounds bleeding through. Reviews highlight flexible ANC control via the app, including adaptive behavior and anti-wind options. The tradeoff is that some modes can reduce cancellation strength compared with a full-max setting.

Android support is repeatedly framed as a strong use case, with modern Bluetooth features and higher-quality codec options that cater well to Android ecosystems.

Android compatibility is frequently highlighted as the best match for this product, since Android devices can access more codecs and future-facing features. Most reports describe stable performance on Android, with fewer issues than on iOS in some tests.

The Bose app is generally seen as essential and functional for modes, device management, and settings, though some workflows (like mode creation) can feel limited or slightly confusing.

The Smart Control app is widely praised for depth and polish, offering fit tests, customization, updates, and sound tools. The main critique is that it can feel feature-dense or that certain controls (like EQ depth) could be more advanced.

aptX Adaptive (including higher-quality variants cited by reviewers) is a key advantage versus some rivals for Android listeners who want better Bluetooth audio performance when supported by their phone.

aptX support (including Adaptive/Lossless on compatible devices) is frequently praised as a differentiator for Android users. Several reviewers also note that audible gains can be subtle versus AAC, and depend heavily on phone support and content quality.

Audio/video sync is usually fine for casual viewing and even editing for some users, but multiple comments suggest latency is not ideal for competitive gaming or fast-reaction play.

For video and casual gaming, sync and latency are generally reported as good, aided by low-latency modes and modern Bluetooth. Competitive gaming may still benefit from dedicated dongle-based solutions, but most users should find A/V sync acceptable.

Bass is consistently described as deep, punchy, and satisfying; some listeners consider it aggressive or dominant, especially out of the box.

Bass is repeatedly described as deep, punchy, and well controlled, adding weight without drowning details. Some listeners feel the stock bass tilt is more consumer-friendly than neutral, and prefer trimming it via EQ.

Battery life is consistently called average for the category: typically around 6 hours with ANC, dropping with immersive/spatial modes, and supported by multiple case recharges.

Battery life is typically around 7 to 7.5 hours per charge in many tests, with ANC reducing runtime in some reports. With the case, total endurance is commonly cited around 30 hours, which is competitive for the premium class.

Bluetooth stability is generally reported as solid across iOS and Android devices, with few or no dropouts in typical use, though some reviewers mention earlier-gen complaints and suggest toggling certain features if problems appear.

Bluetooth stability is generally strong, with several reviewers noting fewer dropouts and good on-the-go continuity. A few reports mention iPhone-related cutouts or codec-dependent behavior (e.g., stereo-to-mono at distance with high-res modes).

Earbud build quality is generally considered premium, with durability expectations aligned to the price; the case gets more mixed feedback on feel and refinement.

Build quality is commonly described as solid and durable, with premium materials and a robust case. Overall impressions point to a flagship-level fit and finish.

Controls are easy to learn and include useful gestures (notably swipe volume), yet multiple reviews mention finickiness and accidental activations; the ability to disable touch controls is an important mitigation.

The case is frequently described as bulky and less premium-feeling than the earbuds themselves; some reviewers also note the buds can be awkward to retrieve.

Case quality is consistently rated premium, with a fabric exterior and solid feel. The main knock is size rather than materials or durability.

Charging is a Gen 2 strong point thanks to wireless charging support, plus fast top-ups via the case; a few notes suggest wireless coil placement can be finicky on some pads.

Charging is a strong point: USB-C and Qi wireless charging are standard, and fast top-ups are commonly quoted around 8 to 10 minutes for about an hour of playback. Battery-protection and intelligent charging modes trade speed and max capacity for longevity.

Codec support is a highlight for many reviewers, especially for Android users, with modern high-quality options noted alongside broad device compatibility.

Codec support is a major selling point, repeatedly cited as future-proof: Bluetooth 5.4 with broad codec options, plus LE Audio/LC3 and Auracast support via updates depending on source device. iPhone users are largely limited to AAC, reducing the practical benefit.

Comfort is widely praised for long sessions, especially once tips and stability bands are dialed in; a consistent caveat is that the shell size may not suit the smallest ears.

Comfort is commonly rated high for a premium TWS, with stable in-ear fit for long listening. The buds are physically large, and some users with small ears or very long sessions report fatigue or pressure over time.

Design is polarizing: many like the sleek, modern look, but the buds are visually and physically large, which can be a problem for smaller ears.

Design is repeatedly described as premium and stylish, with new colorways and a recognizable Momentum look. Many reviews note the external design is very similar to the prior generation, so upgrades are mostly internal.

Tip and wing options are helpful for achieving a strong seal, but multiple reviews note the included range is adequate rather than expansive given the premium price.

Multiple ear tip sizes and fin options are a recurring positive, supporting both comfort and isolation. Some reviewers still struggle to get a consistent seal due to tip shape or softness, so fit can be somewhat ear-dependent.

EQ customization is a frequent criticism: it is typically described as a basic 3-band tool with limited precision, which may frustrate listeners trying to meaningfully reshape the tuning.

EQ tools are considered effective for shaping the sound, and many reviewers recommend using them to tailor bass or clarity. A few power users want a more advanced EQ than the built-in 5-band option and report limitations or compression when pushing bands.

Find-my style tracking and precision locating are not emphasized, and multiple reviewers note it is not on the same level as Apple ecosystem tracking. If you often misplace earbuds, this is a weaker point versus AirPods.

Measured/tonal accuracy is broadly good, but several reviewers note a mild upper-mid/high underemphasis that can read as less crisp detail out of the box. Personalization tools and EQ can compensate, and many still find the tuning musically pleasing.

Accessories commonly include multiple tip sizes and stability bands plus a charging cable; a few reviewers wish for extras like more sizes or a longer cable.

Included accessories are typically appreciated, especially the multiple ear tip sizes and stabilizing fins plus USB-C cable. This variety helps users find a better seal and fit.

Instrument separation is repeatedly rated as strong, helping busy tracks stay organized and making details easier to pick out.

Instrument separation and imaging are strong, with reviewers frequently noting easy placement of instruments and clean layering. This is a recurring reason these are favored for immersive music listening.

At higher volumes, clarity generally holds up well according to multiple impressions, though overall tonal preference still depends on how you feel about the bass-forward tuning.

At higher listening levels, clarity is usually maintained, and multiple sources note low distortion or clean playback. The main caveat is that pushing volume higher to overcome outside noise is not ideal for hearing health.

Noise reduction for calls is frequently praised (including AI-style voice isolation), yet a minority of measurements-based reviews report that wind and background sound can still bleed through depending on scenario.

Noise reduction for calls is inconsistent across reviews. Wind remains the most common weakness, and some tests report background noise suppression that is less reliable than top competitors.

Call quality is widely reported as improved versus earlier generations, often sounding clear and intelligible; however, some tests still find it can struggle in very windy or extremely noisy environments.

Call mic quality is mixed: many find it fine in quiet to moderate settings, and some report clear voice pickup. Others rate it below class leaders, especially outdoors, with processing artifacts or inconsistent clarity in noisy streets.

Midrange presentation is generally clear enough for vocals and instruments, but opinions vary: some hear warmth and natural tone while others cite recessed or uneven mids that can affect certain voices.

Midrange is generally praised for natural vocals and good presence, often cited as a key strength. A few reviewers note an upper-mid dip or a darker voicing out of the box that can reduce perceived clarity until adjusted.

Cross-platform use is broadly positive across phones, tablets, and computers; iOS works well, though several reviewers still note Apple ecosystem extras remain a separate advantage for AirPods users.

Multi-platform use is generally good across phones and computers, but the experience is not equal across ecosystems. iPhone works reliably for basics, yet the most compelling codec and feature benefits largely land on compatible Android devices.

Multipoint is a meaningful quality-of-life feature and is mostly described as seamless for switching between two devices, with occasional notes that pausing one stream before starting another helps.

Multipoint is supported and usually works as expected for switching between two devices. Some reviewers note occasional quirks or platform-specific issues, but overall reliability is viewed as solid after firmware updates.

No summary yet.

Passive isolation is strong when the seal is right, helped by multiple ear tip sizes and stabilizing fins. A few users report seal sensitivity depending on ear shape and tip stiffness, which can impact both sound and ANC.

Portability is mixed: the case is pocketable but noticeably larger than key competitors, and runners often find it inconvenient to carry during workouts.

Portability is good in-pocket for the earbuds themselves, but the fabric case is frequently described as chunky. Several reviewers accept the size as a premium tradeoff, while others prefer smaller cases for everyday carry.

Preset EQ profiles are described as basic and not always effective at fixing core tuning preferences, especially for listeners sensitive to boosted bass or treble.

Sound Personalization and presets are often highlighted as genuinely useful, helping users correct tonal preferences and automate settings via Sound Zones. Results depend on user patience and ear fit, but most find the feature worthwhile.

In-ear detection and related sensors are supported and configurable; at least one review suggests turning detection off if it contributes to unwanted playback behavior or stutters in edge cases.

Sensors such as in-ear detection are generally reported as accurate and convenient, reliably pausing and resuming playback. This contributes to the overall flagship feel and day-to-day ease of use.

Setup is usually straightforward, but several reviews emphasize the app is effectively mandatory for fully managing features like multipoint, modes, shortcuts, and certain tuning behaviors.

Setup is usually straightforward, and firmware updates address some early quirks; most reviewers describe smooth pairing and daily use. A minority report pairing oddities, platform glitches, or UI annoyances that prevent a flawless experience.

Overall sound is widely praised as rich, engaging, and detailed, though it is not tuned for strict neutrality; a few reviewers find the stock profile too boosted at the extremes and harder to correct due to limited EQ.

Across reviews, sound quality is a standout: rich, detailed, and engaging with a spacious presentation. A minority find the stock tuning a bit warm/dark or slightly lacking upper-mid or top-end bite, but EQ and Sound Personalization can dial in clarity.

Soundstage is commonly described as roomy and spacious for earbuds, with immersive modes able to expand the sense of space further (sometimes with tonal side effects).

Soundstage is consistently reported as wide and immersive for true wireless, with a strong sense of space. Some describe it as more expansive than key rivals, while others call it excellent but not the most out-of-head possible.

Spatial/immersive audio features are robust and can sound more natural than many implementations, but not everyone prefers the processing, and it typically reduces battery life.

Spatial audio features are not a focus here, and multiple sources note the lack of built-in spatial audio/head tracking compared with some rivals. For listeners who prioritize immersive spatial modes, this can be a deciding drawback.

Fit security is a major strength thanks to stability bands/wings, with several reviews calling them suitable for workouts and even running, though some users mention footstep thud in ANC mode.

Stability is generally strong, with fins helping keep the earbuds secure during movement and even light workouts. A small subset report fit/seal challenges that can make them feel less locked-in.

Touch responsiveness is generally strong and often praised for quick gesture recognition, but sensitivity can lead to accidental triggers during fit adjustments or certain activities.

Touch controls are generally described as responsive and customizable, with quick mode switching. Some users simply dislike touch input or note occasional mis-triggers in wet conditions, but responsiveness itself is usually strong.

Transparency/Aware mode is generally clear and natural, with useful loud-spike handling in some implementations, but several reviewers still place it behind the very best competitors and note occasional hiss or wind sensitivity.

Transparency is often described as natural and adjustable, with some calling it among the best they have used. A minority report slight hiss/white noise or say it could be more lifelike compared with Apple or Bose in certain environments.

Treble is often described as crisp and detailed without obvious harshness for many, though some reviews report boosted regions that can fatigue sensitive listeners and note limited EQ control to tame it.

Treble is typically smooth, airy, and non-fatiguing, with sparkle that avoids harshness. The main criticism is that the highest frequencies can feel slightly tamed or recessed for listeners who want extra bite and air.

USB-C charging is standard and widely appreciated, with fast-charge behavior commonly referenced for quick listening time boosts.

USB-C charging is standard and frequently mentioned, though some note the case port placement is unconventional. In practice, wired charging is easy, and most emphasis is on the convenience of pairing USB-C with Qi wireless charging.

Voice assistant support is present via shortcut customization, with practical use reported (including Google Assistant), though it is not typically positioned as a headline differentiator.

Volume output is frequently described as loud and satisfying, with enough headroom for travel and commuting environments.

Volume output is generally adequate, but at least one test found the earbuds on the quieter side, sometimes needing near-max volume for certain tracks. Most listening impressions still describe the presentation as full and satisfying at normal levels.

An IPX4 rating is repeatedly cited as sufficient for sweat and light rain, appropriate for workouts but not for full submersion scenarios.

The IP54 rating is frequently mentioned as a meaningful upgrade, making them suitable for workouts, rain, and dust exposure. They are not designed for submersion, so they remain a splash and sweat solution rather than a swim option.

Weight is noticeable for some: a few reviews describe them as heavy or fatiguing after hours, while others find the distribution and fins keep them comfortable. Comfort varies significantly by ear shape and tip choice.
