• RELAXYO Bone Conduction Swimming — biggest strength: IP68 waterproofing plus 32GB of onboard MP3 storage, so you can leave the phone behind and still have music in the water.
• RELAXYO Bone Conduction Swimming — biggest trade-off: 7 hours of playback and a 1.5-hour charge time, and Bluetooth simply cannot travel through water, so swimming always means MP3 mode.
• DOOGEEEco Bone Conduction Headphones — biggest strength: up to 10 hours in Bluetooth mode, a 25-gram titanium alloy frame and partial-charge top-ups that give you 2 hours from 10 minutes of charging.
• DOOGEEEco Bone Conduction Headphones — biggest trade-off: MP3 mode drops to 6 hours, and a full charge takes far longer, so it rewards riders who plug in overnight rather than between errands.
• For cyclists who swim as well: RELAXYO Bone Conduction Swimming.
• For cyclists who want the longer day out and the lighter fit: DOOGEEEco Bone Conduction Headphones.
This is the pair that treats water as the main event rather than an afterthought. The IP68 rating is the headline, and it's backed by a genuine second mode: 32GB of internal storage, which the spec sheet equates to roughly 7,000 songs, plus a magnetic charging cable that doubles as the transfer route from your computer. In other words, the music lives on the headphones. For a cyclist, that matters more than it first sounds. You can load an album or a podcast set, leave your phone in a jersey pocket or at home entirely, and toggle to MP3 mode with a double-press of the power button. On a wet commute or a rainy training loop, the IP68 rating covers sweat and rain too, so the same pair that handles the pool handles the road.
Who should buy it: swimmers who also ride, and riders who want one pair that crosses between the pool, the rain and the road without a phone in the loop. Who should skip it: anyone who wants to keep Bluetooth audio going for a full century ride. Seven hours is respectable, but the 1.5-hour charge time and the fact that Bluetooth can't transmit underwater mean this is a device you plan around, not one you grab and forget.
DOOGEEEco Bone Conduction Headphones: Who It's For
DOOGEEEco approaches the same brief from the endurance side. The claim that stands out is up to 10 hours in Bluetooth mode, which is the kind of number that covers a long ride, a double session, or a full day of errands without a charge. MP3 mode drops to 6 hours, which is still enough for a serious swim block. What makes the battery story genuinely different is the fast-charge behaviour: 10 minutes of charging reportedly returns 2 hours of wireless playback. That's the difference between a dead pair staying dead and a dead pair being usable again before you've finished kitting up.
The fit side is the other half of the pitch. At 25 grams, this is a very light open-ear build, and the frame is flexible titanium alloy that the spec sheet describes as deformation resistant. There's an adjustable strap that rotates 360 degrees, which is the honest answer to the fact that no two heads are shaped alike — bone conduction transducers only sound right when they sit in the correct spot, and a strap you can dial in is how you get there. The controls are physical buttons, which matters when your hands are wet or gloved, and there's a noise-cancelling microphone for calls.
Who should buy it: cyclists and multi-sport users who want the longest possible runtime, the lightest possible frame, and the ability to top up in minutes. Who should skip it: anyone who wants the fastest full recharge. Six hours to full is a long wait, so this rewards the overnight-charging habit. It's also worth noting the colour is blue — a small thing, but visibility on the road is never a bad trait.
Side-by-Side: Which Should You Choose?
• Best for battery life → DOOGEEEco Bone Conduction Headphones, with up to 10 hours in Bluetooth mode versus 7 for RELAXYO.
• Best for quick top-ups → DOOGEEEco. Ten minutes for 2 hours of playback is the single most useful number on either sheet.
• Best for fastest full charge → RELAXYO, at 1.5 hours versus DOOGEEEco's 6 hours.
• Best for the lightest fit → DOOGEEEco at 25 grams, with a 360-degree adjustable strap to dial in transducer placement.
• Best for phone-free listening → Both, in different ways. RELAXYO holds roughly 7,000 songs, DOOGEEEco roughly 8,000 — but DOOGEEEco's MP3 runtime is shorter.
• Best for long multi-day rides → DOOGEEEco, simply because runtime and fast charging beat everything else once you're out past hour seven.
• Best for wet-weather commuting and pool days → RELAXYO, whose IP68 claim is framed around surfing, swimming, running and hiking rather than a single use case.
In my opinion, the deciding question is whether you actually swim in these or just ride in the rain. If you swim — even occasionally — I'd buy the RELAXYO Bone Conduction Swimming, because the IP68 rating and the 32GB MP3 mode are the features that make underwater listening possible at all, and the 1.5-hour charge keeps it ready. If your "cycling earbuds" are really cycling earbuds and the water is only weather, I'd buy the DOOGEEEco Bone Conduction Headphones: 10 hours of Bluetooth runtime, 25 grams on your head and a 10-minute charge that buys 2 hours is a stronger everyday package for a rider. Neither is wrong. They're built for different halves of the same athlete.
FAQ
Both are rated IP68, so both can go in the water. RELAXYO leans harder into it with a 32GB onboard library and clear instructions to switch to MP3 mode before you get in, since Bluetooth can't transmit underwater.
RELAXYO gives up to 7 hours of music and charges fully in 1.5 hours. DOOGEEEco gives up to 10 hours in Bluetooth mode and 6 hours in MP3 mode, with 10 minutes of charging returning about 2 hours.
Both work over Bluetooth 5.4, and both accept file transfers for phone-free playback. RELAXYO mentions a magnetic charging cable for computer transfers; DOOGEEEco lists multi-point connection so you can switch between a phone and a laptop.
DOOGEEEco lists 25 grams with a flexible titanium alloy frame and a 360-degree adjustable strap. RELAXYO uses a memory titanium frame with an open-ear, over-ear fit designed to avoid pressure over long wear. If weight is your priority, the DOOGEEEco figure is the one to note.
