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 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 app is useful for firmware, library management, and Playlist+ tasks, but it is basic rather than feature rich and can feel awkward compared with more polished headphone apps.
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 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.
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 inconsistent. Some reviewers hear solid or even punchier bass, especially underwater or with earplugs, but others call it hollow, woolly, or nearly absent on land.
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 solid for the category, with most reviews landing around the claimed 9 hours over Bluetooth and 6 hours from memory mode, though some testing suggests real-world endurance can fall short of the marketing numbers.
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 is fine for some above-water use, but stability is not flawless. Multiple reviewers mention stutters, disconnects, or pairing friction, and underwater Bluetooth remains impractical as expected.
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).
Build quality comes across as sturdy, flexible, and ready for abuse in the pool or during training. The sealed construction and soft exterior inspire confidence.
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.
The controls are the most common complaint. Physical buttons offer tactile feedback, but many reviewers found them too small, too close together, slow on secondary presses, or easy to trigger incorrectly while moving.
The magnetic proprietary cable supports the waterproof design, but it adds one more special accessory to keep track of, and one reviewer reported unreliable wired file transfers.
The included cases are generally well regarded. Reviewers call them protective and practical, though some found the standard case bulkier than necessary.
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 straightforward once aligned with the magnetic connector, and case-based charging options add convenience, but the waterproof-focused approach means living with a proprietary setup.
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 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 one of the strongest recurring positives. The open-ear design avoids ear-canal fatigue, vibrations are generally well controlled for the category, and several reviewers found them easy to wear for long swims or runs.
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.
The design is sporty and practical rather than stylish. Reviewers like the soft-touch finish and purpose-built form, even if it looks more specialized than everyday headphones.
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.
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 tuning is essentially missing, so you are mostly stuck with the default sound signature.
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 are a plus. Earplugs and a protective case show up repeatedly as useful inclusions, and they materially improve the swim experience.
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 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.
Pushing volume too high hurts sound quality. At max levels, reviewers noted distortion, harsher vibrations, and less pleasant listening.
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 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 usable but not a strength. Voices tend to sound quiet, distant, or light on detail, which fits the swim-first design but limits all-purpose appeal.
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.
Mids and vocals are serviceable rather than standout. They come through well enough for workouts and can sound more balanced underwater, but several reviews say voices lose body or detail above water.
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.
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 support is absent, which limits convenience if you switch between devices often.
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.
The open-ear design provides almost no passive isolation on its own. The included earplugs make a noticeable difference in the pool by reducing splash noise and improving perceived clarity and bass.
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.
The local-memory feature is the reason to buy these. Reviewers like the 8GB storage, drag-and-drop loading, and true phone-free swimming, but Playlist+ is often described as clunky, slow, or awkward, and 8GB trails some rivals.
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.
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.
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, 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.
Sound quality is the main compromise. Underwater playback is often described as good or at least satisfying for the category, while above-water listening ranges from merely okay to clearly weak compared with better open-ear or in-ear alternatives.
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 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 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.
Once the fit suits your head, stability is excellent. Reviewers regularly say the headset stays put through swimming, running, and vigorous movement, though smaller heads can end up with extra rear loop.
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 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 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 acceptable for exercise use, not refined listening. Highs are often described as rolled off, grainy, or slightly distorted when volume climbs.
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 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.
There is enough output for workouts and spoken-word listening, but open-ear use in noisy settings often requires higher volume than ideal.
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.
Water performance is the standout strength. The IPX8 rating and real underwater playback are consistently praised, making these far more convincing for swimmers than most open-ear alternatives.
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.
These are repeatedly described as lightweight and unobtrusive, which helps during long sessions and makes the headset easy to forget once positioned.
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.
