How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a swimming-first pair of bone conduction headphones that doubles as a Bluetooth headset for cycling and running, choose RELAXYO Bone Conduction Swimming; if you need the longer battery life, an LED display on the earpiece and a slightly cheaper-feeling daily driver for pool plus bike, choose Aiandcc Swimming Headphones.
• RELAXYO's biggest strength: a true IP68 rating plus 32GB of built-in MP3 storage, so it survives sweat, rain and pool water while playing music straight off the headset with no phone nearby.
• RELAXYO's biggest trade-off: no LED screen or battery indicator, so you have to trust the 7-hour estimate rather than read the remaining charge at a glance.
• Aiandcc's biggest strength: 8 hours of playtime, roughly 1-hour charging and a built-in LED display that shows battery level and mode, which is genuinely handy when you're heading out for a ride.
• Aiandcc's biggest trade-off: it carries an IPX8 rating with a stated 2-metre/1-hour immersion limit, whereas RELAXYO's IP68 is the more robust water-and-dust claim.
• Who each is for: RELAXYO suits the swimmer-cyclist who wants maximum water protection and a huge offline library; Aiandcc suits the rider who wants longer runtime and visible battery status for mixed land-and-water sessions.
RELAXYO's X26 is built around one idea: get music into your ears without a phone. The 32GB of internal storage holds up to about 7,000 songs, and you load them by plugging the magnetic charging cable into a computer. That single design choice is why it makes sense for lap swimmers and cyclists who don't want to carry or risk a phone. Double-press the power button and you flip between Bluetooth 5.4 and MP3 mode — Bluetooth for the bike, MP3 for the water, because Bluetooth simply can't transmit underwater.
Who should skip it? Anyone who wants to glance at a battery readout mid-ride. There's no display here — just three physical buttons and a 7-hour, 1.5-hour-charge cycle. If you're the type who needs to see the charge level before a long session, that omission will annoy you. Cyclists who ride with one ear open and want a huge offline playlist, though, will find the combination hard to beat.
Aiandcc Swimming Headphones: Who It's For
The Aiandcc S10 attacks the same problem from a slightly different angle. It also packs 32GB of MP3 storage — enough for roughly 8,000 songs — and it also switches between Bluetooth and MP3 mode, with the same caveat that Bluetooth doesn't work underwater. What sets it apart is the LED display. It shows battery level and working mode right on the unit, which removes the guesswork that plagues most swimming headphones. Combined with 8 hours of playtime and a full charge in about an hour, that's a strong package for anyone doing back-to-back sessions.
At 36.6g with a flexible memory titanium frame, it's light and secure, and Aiandcc states it fits with swim caps, goggles and helmets. That helmet line matters for cyclists — it's telling you the open-ear shape won't fight your helmet straps. The IPX8 rating supports immersion up to 2 metres for an hour, which covers pool swimming and most water sports. It also supports MP3, WAV, APE and WMA files, so you're not locked into one format when loading music.
The trade-offs are worth naming. IPX8 with a stated depth-and-time limit is a narrower water claim than RELAXYO's IP68, so if you're a rough-water or surf type, that difference matters. And the two pre-loaded test songs are a nice unboxing touch but not a substitute for a real battery indicator you can trust over months. For pool swimmers and cyclists who want visible battery status and longer runtime, it's a sensible pick.
Side-by-Side: Which Should You Choose?
• Best for battery life → Aiandcc Swimming Headphones. 8 hours versus 7, and it charges in about an hour versus RELAXYO's 1.5.
• Best for battery visibility → Aiandcc Swimming Headphones. The LED display shows charge and mode; RELAXYO has no screen.
• Best for offline music capacity → a tie. 32GB on both, roughly 7,000 songs on RELAXYO and 8,000 on Aiandcc by their own counts.
• Best for cyclists who ride with a helmet → Aiandcc Swimming Headphones, since Aiandcc explicitly lists helmet compatibility in its fit description.
• Best for runners and swimmers who want simple controls → RELAXYO Bone Conduction Swimming. Three buttons, one of which handles power, play/pause, calls and mode switching.
• Best for audio format flexibility → Aiandcc Swimming Headphones. MP3, WAV, APE and WMA versus a standard music-file transfer on RELAXYO.
• Best for microphone calls → Aiandcc Swimming Headphones, which calls out a built-in mic for clear calls; RELAXYO mentions call answering and hanging up but not mic quality.
If I had to pick one, I'd buy the RELAXYO Bone Conduction Swimming. In my opinion, the IP68 rating is the more convincing water story for someone who actually swims and then rides, and the open-ear bone conduction design plus the titanium frame is exactly what I'd want for hearing traffic on the bike. The missing battery display is a real annoyance, but it's a minor one next to stronger water protection. Choose the Aiandcc instead if runtime and a visible charge readout matter more to you than the extra water margin — that's a completely defensible call.
FAQ
Both work for cycling since they share Bluetooth 5.4 and a 10-metre wireless range. RELAXYO leans on open-ear bone conduction for awareness and a bendable titanium frame, while Aiandcc says it fits with helmets. I'd give Aiandcc the edge only if you want the LED battery readout on the bike.
RELAXYO states up to 7,000 songs from 32GB, and Aiandcc states up to 8,000. Either way you're carrying far more than any single workout needs, so capacity isn't the deciding factor here.
Both are 32GB bone conduction headsets with the same Bluetooth version, so the value question comes down to which extras you want: Aiandcc gives you 8 hours, an LED display and a mic; RELAXYO gives you IP68 and simpler controls.
