• Sanag's biggest strength: a genuinely swim-ready design — IPX8 waterproofing rated for submersion up to 2 meters, plus 32GB of built-in memory so you can leave your phone on the pool deck.
• Sanag's biggest trade-off: it's a sport-specific tool, not a lifestyle bud. No noise cancellation, a fairly plain plastic build, and you must switch to MP3 mode underwater because Bluetooth can't transmit through water.
• Xoruezls' biggest strength: comfort and endurance — roughly 5g per bud, a flexible clip that sits outside the ear canal, and up to 10 hours per charge (up to 50 hours total with the case).
• Xoruezls' biggest trade-off: it is not a swimming product. There's no waterproofing rating on the sheet, so keep it out of the pool.
• Buy Sanag if your priority is pool training, open-water swimming or sweaty outdoor sessions where water resistance is non-negotiable.
• Buy Xoruezls if you want something light enough to forget you're wearing for work, workouts, travel and everyday listening.
Sanag built this around one clear idea: audio that survives water. The IPX8 rating covers submersion up to 2 meters, and the one-piece seamless enclosure is designed so water doesn't find a way in. That makes it suitable for pool laps, ocean swimming, and the kind of sweaty, rainy outdoor sessions where most earbuds quietly give up. If you've ever had a pair die after a hard training block, the spec sheet here is aimed squarely at you.
The second half of the story is the 32GB of built-in memory. Because Bluetooth signals can't travel through water, Sanag gives you MP3 mode — you load songs onto the headphones and swim with no phone involved at all. On land, you can switch back to Bluetooth 6.0, which the sheet says pairs in about 3 seconds and reaches up to 50 feet. Battery is rated at up to 8 hours of music or calls, with roughly a 2-hour charge time, which is enough for a long pool session or a swim meet without hunting for a charger.
Xoruezls Open Ear Earbuds: Who It's For
Xoruezls went the other direction: it optimized for comfort you can wear for hours. Each bud weighs around 5 grams, and the external clip structure rests outside the ear canal rather than sealing inside it. That's the whole point of the open-ear format — no plugged-up, enclosed feeling, and you stay aware of what's happening around you. For office work, studying, walking, commuting and travel, that combination is genuinely pleasant in a way sealed buds often aren't.
The clip is also the stability story. Flexible clip-on earbuds wrap around the ear to hold position through running, gym work and repeated movement — the exact situations where ordinary buds loosen and need constant fiddling. And the battery numbers are the headline: up to 10 hours from the buds themselves and up to 50 hours total with the charging case, plus an LED display so you can check remaining power before you head out. For a full workday plus a workout, that's a lot of headroom.
Sound comes from 16.3mm dynamic drivers, which the sheet frames around detailed stereo separation, clear upper frequencies and satisfying bass for music, podcasts, video and calls. Bluetooth 5.3 handles the wireless side and the product supports Android devices. I'd skip Xoruezls if swimming or heavy water exposure is on your list — nothing in the data sheet claims a water-resistance rating, so the pool is off-limits. Its touch controls are also a matter of taste; some people love them, some find them fiddly mid-run.
• Best for swimming and water sports → Sanag Swimming Bone Conduction. IPX8, 2-meter submersion, one-piece seamless build. This isn't close.
• Best for all-day comfort and light weight → Xoruezls Open Ear Earbuds. Around 5g per bud with a clip that sits outside the ear canal.
• Best for total battery endurance → Xoruezls Open Ear Earbuds. Up to 10 hours per charge and up to 50 hours with the case, versus Sanag's 8 hours.
• Best for phone-free listening → Sanag Swimming Bone Conduction. The 32GB of built-in memory and MP3 mode mean no phone required at all.
• Best for running, gym and commuting → Xoruezls Open Ear Earbuds. The flexible clip is purpose-built for movement, and the 16.3mm drivers suit everyday music and podcasts.
• Best for calls in loud places → Sanag Swimming Bone Conduction. The built-in mic uses ENC to cut background noise in pools, gyms and outdoor settings. Xoruezls lists call support but no noise-cancellation spec.
• Best for staying aware of traffic and surroundings → a tie. Both are open-ear designs that leave your ear canal unsealed, which is the core benefit of the format.
• Best for travel and office days → Xoruezls Open Ear Earbuds. Lighter, longer-running, and shaped for extended wear rather than athletic punishment.
In my opinion, these aren't really competitors — they're answers to different questions. If I swam laps, trained in open water or regularly got caught in the rain on long rides, I'd buy the Sanag Swimming Bone Conduction without hesitation, because the IPX8 rating and 32GB of offline memory solve problems nothing else on this page solves. For everyone else — the gym-goer, the commuter, the person who wants buds light enough to forget — I'd buy the Xoruezls Open Ear Earbuds, because the comfort, the clip stability and the 50-hour total battery make it the better everyday companion. Pick based on where you'll actually wear them, and check the current price on Amazon before you commit, since that's the one number that should decide the tie.
FAQ
Yes, according to the specs. It carries an IPX8 rating with submersion up to 2 meters and a one-piece seamless design. Just remember to switch to MP3 mode in the water, because Bluetooth signals can't transmit underwater.
I wouldn't. The data sheet lists no water-resistance rating for it, so it's best treated as a sweat-friendly gym and running pair rather than a swimming one. Keep it dry and it should serve you well.
Xoruezls wins on paper: up to 10 hours per charge and up to 50 hours total with the charging case. Sanag is rated at up to 8 hours of playback with about a 2-hour charge time — plenty for a training session, but shorter overall.
Sanag has the edge for noisy environments. Its built-in microphone uses ENC (Environmental Noise Cancellation) to reduce background noise, which the sheet specifically ties to pools, gyms and outdoor settings. Xoruezls supports calls but lists no noise-cancellation feature.
