ANC effectiveness is usually rated good but not class-leading; it can handle commute rumble well, yet several reviewers say Sony/Bose options suppress more, especially in the upper ranges. Noise cancelling and awareness modes are often limited in fine control, with some reviews noting on/off style behavior and few intensity tweaks compared with competitors.
Android compatibility is good overall, and Android users with aptX-capable Snapdragon devices can get the most from Lossless/Adaptive modes; on other phones it still works well but with fewer codec benefits.
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 companion app is feature-rich for personalization, EQ, control mapping, and updates, but some sources mention slow loading or occasional instability, and several note it is effectively required to get full value.
aptX support is a highlight, with repeated mentions of aptX Adaptive/Lossless (and sometimes aptX Voice) as a key advantage for compatible Android devices.
Video latency is generally reported as well controlled, with reviewers noting little to no audio-video sync issues during typical streaming and YouTube viewing.
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 frequently praised as impactful and well controlled, with Immersion mode letting you add heft without obvious bleed; a few listeners still find the default or certain profiles bass-light or overly sculpted.
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 marketed as long, but real-world reports vary, with at least one standardized test landing closer to about six hours; most still consider it adequate for daily use.
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 mostly strong with quick reconnects, though at least one review reports occasional stuttering in specific conditions.
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 generally viewed as solid and premium-feeling, with durable housings and a well-made overall package.
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.
The charging case is often described as somewhat bulky but generally sturdy with strong magnets; a few comments mention hinge/handling quirks.
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 with fast-charge support and both wired and wireless options, though a small number of users report the case can get warm on a wireless pad.
Codec support is broad, including aptX Adaptive and aptX Lossless alongside AAC/SBC; the main caveat is that benefits depend on having a compatible source and LDAC is missing.
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.
Long-wear comfort is highly personal: some find the fit secure and comfortable, especially with wings, while others report pressure, heat, or discomfort due to the large shells.
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 distinctive and polarizing: the large circular faceplate stands out, but many note the buds are physically big and may look or feel awkward in smaller ears.
Ear tip options are generous, typically including several silicone sizes plus at least one foam set, which helps comfort and isolation when matched correctly.
EQ tuning is essentially missing, so you are mostly stuck with the default sound signature.
EQ options are strong for the category, typically including a 5-band ProEQ plus an Immersion bass slider to fine-tune tonality after personalization.
Frequency response accuracy is divisive: some praise a balanced, natural tuning once updated, while others cite measured or perceived tonal issues out of the box that may require firmware and EQ.
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 a highlight, with multiple tip sizes, foam options, and stabilizing wings helping users dial in fit and seal.
Instrument separation and imaging are commonly highlighted as a standout, with precise placement and clean layering across busy mixes.
LDAC is repeatedly called out as not supported, so Android users who rely on LDAC for high-bitrate Bluetooth may prefer alternatives.
Pushing volume too high hurts sound quality. At max levels, reviewers noted distortion, harsher vibrations, and less pleasant listening.
Clarity at higher volumes is typically strong, with multiple sources noting low distortion and intelligible detail even when played loudly.
Noise and wind reduction on calls is frequently reported as effective, helping keep speech understandable in busy or windy environments.
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 quality is generally above average, with voices described as clear and intelligible; a few reviewers still note slight processing or that top rivals edge it out.
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 clear and present, but can sound forward or radio-like depending on the AAT profile and firmware, so some users prefer minor EQ adjustments for balance.
Multi-platform use is supported across phones and computers, but fidelity and feature access can vary by platform, with iOS often limited to AAC and Android benefiting more from aptX.
Multipoint support is absent, which limits convenience if you switch between devices often.
Multipoint connectivity is a consistent win, with reviewers reporting reliable dual-device pairing and fast handoff between phone and computer/tablet.
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 depends heavily on getting a good seal; with the right tips, attenuation is described as decent, but it is not the main selling point versus active cancellation.
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.
Personalized AAT profiles can produce dramatic, often positive changes, but results vary by listener and tips; some profiles trade a sense of spaciousness for extra punch or focus.
In-ear sensors for auto play/pause are commonly mentioned and generally work as expected, with options to change or disable behavior in the app.
Setup and daily usability are good once configured, but some reviews describe the experience as less polished than rivals because controls and tuning can require initial tinkering.
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.
Sound quality is the main strength: many reviews describe a clean, low-distortion, spacious and highly detailed presentation, especially after Masimo AAT personalization and/or EQ tweaks, though a minority found stock tuning or earlier firmware disappointing.
Soundstage is widely described as unusually wide and open for true wireless, with good spacing; a few reviews note it can feel a bit flatter in depth compared with the very best rivals.
Spatial audio gets mixed reactions: some find it immersive and bubble-like, while others call it subtle or underwhelming, and it is typically not head-tracked.
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 usually good when the right tips and wings are used, though some users report slight movement during chewing or vigorous motion without added support.
Touch controls are commonly described as responsive and highly customizable, with reliable gesture detection and audible feedback.
Transparency or social mode is usable but mixed: some call it smooth and subtle, while others find it less natural, occluded, or slightly artificial versus AirPods-class passthrough.
Treble is acceptable for exercise use, not refined listening. Highs are often described as rolled off, grainy, or slightly distorted when volume climbs.
Treble tends to be detailed and airy, but reports vary from smooth and controlled to tinny or over-sharpened on older firmware or specific personalized profiles.
USB-C charging is consistently supported and frequently mentioned as the standard wired option.
Voice assistant integration is supported through touch controls, with reports of common assistants working reliably when mapped.
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 often described as louder than average with plenty of headroom, useful for dynamic music and noisy environments.
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.
IPX4 water and sweat resistance is consistently noted, making the earbuds suitable for light workouts and rain, though not for submersion.
These are repeatedly described as lightweight and unobtrusive, which helps during long sessions and makes the headset easy to forget once positioned.
Weight comfort is a recurring tradeoff: the earbuds are heavier and more noticeable than many rivals, which can cause fatigue for smaller ears.
