ANC is widely viewed as strong for the category, but wind performance is a recurring weakness in several reviews and some listeners notice a faint hiss in very quiet rooms. Mode switching is straightforward, but several reviewers want finer ANC intensity controls and better ways to access wind-related settings without opening the app.
Android support is strong, helped by features like Fast Pair and LDAC compatibility on supported phones.
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 Status Hub app is generally seen as clean and useful for EQ and features, though some reviewers flag firmware/update hiccups or missing toggles for certain behaviors.
Some reviews explicitly note the lack of aptX-family support, which may matter to Android users who prefer Qualcomm codecs.
Latency is described as typical for Bluetooth: fine for most video, but not ideal for competitive gaming and some reviewers wish for a dedicated low-latency mode.
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 generally described as deep and controlled, but some listeners want more punch or find the low end a bit warm depending on tips/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 mixed: some see close to the rated numbers in lighter use, while others measure around 5–6 hours with ANC and/or LDAC, which can feel short for the price.
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 connections are usually stable and easy to pair, though a few reports mention occasional quirks during reconnection or device prioritization.
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.
Overall build quality is viewed as premium, though there are occasional reports of small durability quirks such as case contact issues.
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.
Physical buttons are appreciated for tactile control, yet multiple reviewers dislike that key button functions are fixed and not fully remappable.
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 sturdy with strong magnets, but a few complaints include one-hand opening difficulty or isolated hardware/connector issues.
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 convenient with USB-C and wireless charging support noted across reviews, and case-to-bud top-ups are generally quick.
Codec support is a highlight, with broad coverage including common codecs plus modern options mentioned across reviews.
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 one of the strongest themes, with many reviewers reporting hours-long wear without hot spots once the right tips are chosen.
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 stands out with a distinctive blocky stem look and premium finishes that many reviewers find sharp and upscale.
Tip selection is commonly limited to three sizes, which most can work with but feels sparse at this price tier for very small or very large ears.
EQ tuning is essentially missing, so you are mostly stuck with the default sound signature.
EQ customization is a major strength, with an 8-band EQ and advanced tweaking options that let users significantly reshape the sound.
The find-earbuds tools (audible beeps and last-known location style tracking) are generally useful and easy to trigger in the app.
Default tuning is often described as balanced or close to a preference curve, and the multi-driver setup helps maintain clarity across lows, mids, and highs.
Accessories are a plus. Earplugs and a protective case show up repeatedly as useful inclusions, and they materially improve the swim experience.
Instrument separation and imaging are consistently strong, helping complex mixes stay organized even with bass-forward tracks.
LDAC support is consistently highlighted as a premium feature, with the usual tradeoff of higher power draw in real-world use.
Pushing volume too high hurts sound quality. At max levels, reviewers noted distortion, harsher vibrations, and less pleasant listening.
At higher volumes, distortion is generally kept in check, with some reviewers noting the sound stays composed near the top of the range.
Noise reduction for calls and ANC-related wind filtering helps in many scenarios, but results vary, with multiple reviewers pointing to wind as the hardest condition.
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 clear in quiet settings, but some reviews note compression or muffling as background noise rises, and wind can be a challenge in certain tests.
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 comes through clearly with strong vocal presence and good musical detail, especially with the Signature or Knowles-style tunings.
Compatibility across phones and computers is broadly positive, with some caveats around platform-specific codec support (notably iPhone and LDAC).
Multipoint support is absent, which limits convenience if you switch between devices often.
Multipoint works well for many users with quick switching, but at least one review reports finicky behavior that required manual device management.
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.
With ANC off, passive isolation is described as usable but not standout, and tip choice plays a big role in the seal.
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.
Preset EQs provide meaningful variety, but naming can be confusing and some presets (especially brighter ones) may not suit everyone.
Sidetone is a well-liked call feature that helps users regulate their speaking volume and feel more natural on calls.
Setup is usually quick and straightforward, with several reviews praising how easy pairing and basic configuration are.
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, Pro X is praised for lively, detailed sound that competes with premium flagships, though a few reviewers call it more of an all-arounder than a market leader.
Soundstage is typically moderate rather than huge, but positioning and spatial precision are frequently called out as a strength.
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.
Fit stability is generally good for daily use and light workouts, but removing fit-wings and tip choice can affect how locked-in it feels for some users.
Touch controls offer a large target and good customization, but sensitivity can be hit-or-miss for some users and swipe gestures are sometimes expected but not always present.
Transparency/ambient mode is often rated excellent with multiple strength levels, though higher settings can introduce hiss, occlusion, or extra white noise for some ears.
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 mostly clean and detailed, but certain presets can sound bright or fatiguing and one review notes slightly restrained upper-treble bite out of the box.
USB-C is standard here and is repeatedly mentioned as the primary wired charging option.
Voice assistant support is present via controls, but it is treated as a basic convenience feature rather than a standout differentiator.
There is enough output for workouts and spoken-word listening, but open-ear use in noisy settings often requires higher volume than ideal.
Volume gets loud enough for most use, but a few reviews want more headroom outdoors or note it is not the loudest in its class.
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 IP55 rating is repeatedly cited as a meaningful durability perk for sweat, rain, and dust exposure.
These are repeatedly described as lightweight and unobtrusive, which helps during long sessions and makes the headset easy to forget once positioned.
