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. "

Reoccurring Problem

These are absolutely brilliant headphones for running and particularly swimming, whilst working!! However I have been through two pairs now and having looked at other reviews it is clear that Shokz have a problem with the Openswim that they really should have fixed by now. Essentially after some time the left ear phone stops working and then after bit longer the whole unit stops working. I have looked after mine well so do not think it is anything I have done to damage them. My second pair came as a warranty replacement but now they have stopped working, Shokz are refusing to replace them as they are counting the warranty period as starting from when I got the first pair rather than the replacement pair. The problem is that they are by far the best headphones for swimming on the market, so I have probably no choice but to purchase another pair at the 15% discount Shokz have offered me.

Produit génial, je ne peux plus m en passer ❤️

Cela fait des années que j utilise ces écouteurs à raison de 4 séances de 1 heure chacune en mer. Le son est extraordinaire, immersif, il tient parfaitement et ultra léger. Après quelques soucis la première année ( son sur une oreille particulièrement) le SAV a été très réactif et professionnel et m'a remplacé le produit par du neuf. Je suis heureuse de partager ma très bonne expérience et remercie la. Marque pour le produit et pour son sérieux.

Best Mp3 for swimming, confort and long lasting

I think it;s best mp3 for swimming, it's confortable, easy to change song, quality of sound is very good under water with caps.
i had the first one in July 2019, it workes perfectly untill i damaged it myself, otherwise if you threat it with extreme care (after workouts), dont bend it, it will last 3 4 years for sure or longer ( i have used a lot), also on the sea.

charging is fast and battery really last a lot, 4GB is more then enough, clearly no blueth (no needed under water).

i can only recommend it, vs sony or other cheap brands.
Definitely worth the money if you have to swim a lot.
also usefull for other sports (although i own the areopex for running with blueth)

Awesome product

This is my second pair. The first pair stopped working on one side after 14 months . The company replaced them with no issues whatsoever. Total game changer as the sound quality is spot on . Only issue is you have to download tracks the old way so you can't use Spotify etc but I knew that before I bought them . Get them bought and you won't get bored in the pool anymore

Game Changer

I’ve started swimming over an hour at a time and it flies by with some music going. These originally hurt my ears but I’ve moved my goggles up a bit and they now fit perfectly. I now love swimming on a whole new level. Thanks for producing such a quality product! Looking forward to the next generation 😉
