If you want a headphone you can genuinely wear in the pool — bone conduction, open-ear, with a built-in music player for underwater laps — choose ZOVIMAX Bone Conduction Headphones; if you need featherweight clip-on earbuds for running, cycling and all-day wear with a pocketable charging case, choose crowm Clip.
• ZOVIMAX's biggest strength: IPX8 waterproofing plus a built-in MP3 mode with 8GB of memory, so you can swim with music and no phone at all. Its real trade-off: a hook-style bone conduction band that's bulkier than clip buds, and Bluetooth simply doesn't work underwater — you must switch modes.
• crowm Clip's biggest strength: 4.1g per bud with a flexible C-shaped silicone bridge, a 30-hour total battery figure via the charging case, and a fit that plays nicely with glasses and small ears. Its real trade-off: no water protection rating is listed, so swimming is out, and noise control is listed as "None."
• Pick ZOVIMAX if you swim, dive, or want phone-free playback from internal memory.
• Pick crowm Clip if you want near-weightless buds for workouts, commuting and calls, plus the convenience of a case.
• Neither is "better" overall — they solve different problems, and the right answer comes down to water versus weight.
The ZOVIMAX X7 MAX is built around one idea: music where most headphones can't go. The IPX8 rating means it's designed to handle full submersion up to 5 meters deep for as long as 2.5 hours. That's not "sweat-resistant" marketing — it's a genuine swimming spec. And because Bluetooth can't transmit through water, ZOVIMAX pairs that rating with an 8GB internal memory and an MP3 mode you toggle with a double-click. The brand says that's enough room for up to 2,000 songs. You copy files by connecting the magnetic charging cable to a computer, which exposes the built-in USB memory.
Who should buy it: swimmers, divers, water-aerobics people, and anyone who wants to leave the phone in a locker and still have music. The 8GB memory plus MP3 mode is the whole point.
Who should skip it: if you mostly want discreet earbuds for the office, calls all day, or slipping into a pocket, the hook-style open-ear band is the wrong shape for you. And note the MP3-mode caveat — expect to manage files from a computer, and remember Bluetooth won't work once you're submerged. A 2-year warranty is listed.
crowm Clip: Who It's For
The crowm Clip Gen 3 goes the opposite direction: make the buds disappear. Each one weighs 4.1g, and the C-shaped soft silicone bridge is designed to flex without irritating your ear. That shape is specifically aimed at people whose ears are too small for typical buds and at glasses and earring wearers — a real, concrete fit claim rather than a vague "comfort" line. The buds are white, and they come with a white plastic charging case that measures roughly 2.55 by 1.77 by 1.38 inches.
Audio runs through 13mm dynamic drivers with a 20Hz frequency response and 110dB sensitivity, and crowm claims minimal sound leakage. Bluetooth 6.0 is on board with a listed 10-meter (33-foot) range, plus dual music and gaming modes with 60ms latency — the gaming figure matters if you watch video or play on your phone and hate lip-sync lag. Controls are touch-based: tap to play, pause, skip, or take a call.
Battery is the headline number. Each charge gives 6 hours of standalone playback, stretching to 30 total hours with the case, and a full charge takes 1.5 hours over USB-C. For a daily commute, a long flight, or a full workday of calls, that case is the difference between "charge tonight" and "charge this week."
Who should buy it: runners, cyclists, gym-goers, commuters, glasses wearers, and anyone with small ears who finds normal earbuds painful or loose. Who should skip it: swimmers — no water rating is listed — and anyone who wants active noise cancellation, since noise control is listed as "None." Warranty is 1 year.
Side-by-Side: Which Should You Choose?
• Best for phone-free playback → ZOVIMAX. The 8GB internal memory (up to 2,000 songs) is something crowm Clip simply doesn't offer.
• Best for all-day battery → crowm Clip. 6 hours per charge, 30 hours with the case, versus ZOVIMAX's up to 12 hours from a single charge.
• Best for glasses wearers and small ears → crowm Clip. The 4.1g buds and flexible C-shaped bridge are designed around that exact problem.
• Best for low-latency gaming and video → crowm Clip. The 60ms dual-mode figure is the concrete advantage here.
• Best for situational awareness on land → a tie, with a caveat. Both are open-ear by design, but crowm's buds sit lighter and more discreetly.
• Best for a discreet, pocketable setup → crowm Clip. The case is small and the buds vanish in your ears; ZOVIMAX is a visible band.
• Best for calls on the move → crowm Clip, given its mic and touch controls — though ZOVIMAX also lists an enhanced call system for land use.
In my opinion, these two don't really compete — they cover opposite halves of a fitness routine. If your workout happens in water, I'd buy the ZOVIMAX Bone Conduction Headphones without hesitating: the IPX8 rating and the 8GB MP3 mode are the only things on this page that let you swim with music and no phone. If your training is dry — running, cycling, lifting, commuting — I'd pick the crowm Clip, because 4.1g buds, a 30-hour case and a fit built for glasses wearers will get worn far more often than a band you have to strap on. Buy for the environment you'll actually use it in. And check the current price on Amazon before you commit, since that's the one variable these specs can't tell you.
Yes — that's its core purpose. It carries an IPX8 rating for submersion up to 5 meters for up to 2.5 hours. Just switch to MP3 mode first, because Bluetooth can't transmit through water.
No water-resistance rating is listed for it, so I'd treat it as a land-only headphone for workouts, commuting and calls. For swimming, the ZOVIMAX is the one with the relevant spec.
ZOVIMAX lists up to 12 hours of playback with a 2-hour charge. crowm Clip lists 6 hours per charge, extended to 30 hours total with its charging case, which recharges in 1.5 hours.
crowm Clip is the clearer match — each bud is 4.1g with a flexible C-shaped silicone bridge designed to fit small ears and sit alongside glasses and earrings. The ZOVIMAX is a hook-style band with an adjustable strap, so it fits differently.
