Expert Reviews

“They’re not cheap, but these are the most complete, high-tech waterproof headphones on the market. The sound is bone-conducted from beside your ear, preventing the risk of swimmer’s ear and other potential plugged-ear problems.”
“Perfect for swimmers in particular, the Aftershokz Xtranierz are an appealing set of bone-conducting headphones. We just wish they had Bluetooth connectivity for those out of the pool times.”
" Sound is incredible underwater thanks to a dedicated swimming EQ, with the bone-conduction pads sitting on your cheekbones and the ear-hook design resting comfortably under a hat or goggles. "

Amazing product for swimming

After trying various "waterproof" headphones on the market I eventually found these ones, and they are excellent. Other makes get worse when they go in water but these actually get better. I would highly recommend these to any swimmers

Great for swimmers

Have been using my latest OPENSWIM for 2 weeks now, some feedbacks below:

1. Solid Sound Quality: Tunes sound clear both in and out of the water. No compromises on audio, whether you're swimming laps or chilling poolside.

2. Easy Mode Switch: Seamless transition between swim mode and regular mode. No hassle, just hit play and go.

3. Consistent Performance: Audio stays solid above and below water with earplugs. Keeps the vibes flowing, no matter the depth.

4. Long Battery Life: Battery lasts, and it tells you the battery level when you switch the headphone on, perfect for all-day adventures.

5. Song Selection Limitation: Only downside? A bit limited on song choices. Not a deal-breaker for me tho.

Outstanding product!

I have recently just had my second baby and wanted to get back into swimming and potentially sign up to a triathlon in the near future! I find swimming to occasionally be a little tedious as I do love my music! Therefore, swimming headphone were a must! I did lots of research and Shokz were the winner and since using I am not surprised at all as they are simply fantastic! Thank you shokz for creating such a wonderful product!

Game changer

Fantastic product, clarity underwater genuinely surprised me! Great battery life and ability to skip, shuffle, chance volume etc is all you need. Yes, of course it would be great to be able to download from Spotify etc and be able to link via Bluetooth but water kinda gets in the way of that ;)

Genuine game changer for me and my long distance swimming
