How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a headset you can actually take underwater, choose mojawa Purra Swim IP68; if you need all-day open-ear comfort with a charging case that keeps you going for days, choose dufiga Open Ear Headphones.
• mojawa Purra Swim IP68 — biggest strength: IP68 waterproofing rated for underwater use down to 8.2 feet, plus a 32GB MP3 mode with room for up to 8000 songs, so it keeps working where Bluetooth simply cannot.
• mojawa Purra Swim IP68 — biggest trade-off: It is a swim-first tool. Bluetooth tops out at a 10-meter range and does not work underwater at all, so you have to switch modes deliberately before you get in the pool.
• dufiga Open Ear Headphones — biggest strength: A 300mAh charging case that supports 12–15 full recharges, pushing total music time past 80 hours, with 6 hours per earbud on a single charge.
• dufiga Open Ear Headphones — biggest trade-off: IPX7 is splash and sweat protection, not swim-grade. The clip-on design is built for running and gym work, not laps.
• Who each pick is for: mojawa for swimmers and water athletes who want music with no phone nearby; dufiga for runners, gym-goers and commuters who want light open-ear buds and a battery case they rarely have to plug in.
This is a bone conduction headphone built around one job: surviving water. The housing is fully sealed and rated IP68, which the spec sheet ties to use at depths up to 8.2 feet. That is a real, specific number, and it matters because most "waterproof" sports headphones are rated for rain and sweat, not submersion. If you swim laps, this is the category of product you need.
The clever part is the dual-mode design. On land you stream over Bluetooth 5.3 within a 10-meter range. Underwater, Bluetooth is useless — physics, not a defect — so you switch to MP3 mode and play from 32GB of internal storage holding up to 8000 songs. That means no phone on the pool deck, no armband, no waterproof pouch.
Who should buy it: lap swimmers, open-water swimmers, triathletes, and anyone who wants music during water sports without carrying a phone. Who should skip it: if you mostly want earbuds for the gym, running or office calls and you never get in the pool, you are paying for waterproofing you will not use. Also skip it if you want a pocketable charging case — this one is worn, not stored.
dufiga Open Ear Headphones: Who It's For
dufiga takes the opposite approach. Instead of sealing everything into one wearable unit, it splits the design into two clip-on earbuds plus a charging case. Each earbud weighs 0.18 oz, which is genuinely tiny, and the soft silicone build is meant to sit outside the ear canal rather than plug into it. The brand's own description talks about avoiding that plugged-in feeling, and the open-ear shape is the whole point: you hear traffic, gym announcements and people talking to you.
The headline feature is stamina. Each earbud runs about 6 hours, and the 300mAh case supports 12–15 full recharges, which the spec sheet totals at more than 80 hours of music time. A Type-C port handles charging, and the LED display shows the status of both the earbuds and the case. For a runner who forgets to charge things, that is a meaningful cushion.
Connection is Bluetooth 5.3, and dufiga emphasizes low latency for video and stable calling. Controls are physical buttons rather than touch, which the brand frames as a way to prevent accidental taps — a real annoyance on touch-sensitive buds. Water resistance is IPX7, so sweat, rain and the occasional splash are fine.
Who should buy it: runners, cyclists, gym regulars, dancers, and anyone who wears glasses and wants buds that stay put. Who should skip it: swimmers. IPX7 is not swim-grade, and there is no onboard storage, so you need your phone within Bluetooth range. If you want to take music into the water, this is the wrong tool.
Side-by-Side: Which Should You Choose?
• Best for all-day battery convenience → dufiga Open Ear Headphones. 6 hours per earbud plus a case that recharges them 12–15 times, past 80 hours total.
• Best for running, gym and cycling → dufiga Open Ear Headphones. Clip-on, 0.18 oz per bud, IPX7, and it plays nicely with glasses and helmets.
• Best for phone-free workouts → mojawa Purra Swim IP68. 32GB of storage and up to 8000 songs means you can leave the phone in the locker.
• Best for hearing your surroundings → dufiga Open Ear Headphones. The clip-on open-ear design is explicit about letting outside sound in for safety.
• Best for outdoor calls and video → dufiga Open Ear Headphones. Bluetooth 5.3 with the brand's low-latency and call-stability claims.
• Best for a single wearable unit → mojawa Purra Swim IP68. No case to lose, no separate buds to misplace.
• Best if you wear a swim cap or goggles → mojawa Purra Swim IP68. The titanium frame is designed to sit alongside that gear.
• Best for noise cancellation → mojawa Purra Swim IP68. It lists active noise cancellation; dufiga lists none.
In my opinion, these two are not really competitors — they are answers to different questions. If you swim, buy the mojawa Purra Swim IP68. The IP68 rating and the 32GB MP3 mode are the two things no ordinary open-ear headphone can match, and they are exactly what water use demands. If you run, lift, ride or commute and never get in a pool, I would buy the dufiga Open Ear Headphones: the clip-on fit, button controls and the charging case that keeps going for days are more useful day to day. Pick by where you sweat, not by which looks nicer on paper.
how to bone conduction earphones work
Bone conduction drivers vibrate and send sound through the bones in front of your ear, bypassing the eardrum and leaving the ear canal open. That is why open-ear designs like these let you hear your music and the world around you at the same time.
how to wear bone conduction earphones
You rest the transducers against your cheekbone just in front of the ear, not inside it. The mojawa Purra Swim IP68 uses a titanium alloy frame that fits under swim caps and goggles; the dufiga Open Ear Headphones clip over the ear with a soft silicone surround.
how to use bone conduction earphones
Pair over Bluetooth, then use the onboard buttons to play, pause, skip and take calls. On the mojawa Purra Swim IP68 specifically, remember Bluetooth does not work underwater — switch to MP3 mode from the 32GB storage before you swim.

Not automatically. Ratings vary widely: the mojawa Purra Swim IP68 is IP68 and rated for underwater use to 8.2 feet, while the dufiga Open Ear Headphones are IPX7, which covers sweat, rain and splashes but not swimming.
