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. "

Couldn't be happier

The best thing ive treated myself to in a long time. Amazing in the pool making swimming so much easier and more enjoyable. I've also used them for running, and as they dont go in your ears you can still hear people and traffic etc which makes me feel much safer. And they NEVER budge even during a 2.5 mile swim they didn't move. Loading Music is so easy to. Havent got a bad word to say about them. I loved them so much my nan and cousin both bought themselves a pair on my reccomendation.

Great swimming headphones

In common with another reviewer, I used Sony Waterproof earphones to stave off the boredom of swimming! However, when they eventually broke, I tried the Xtrainerz. Pre lock-down I was swimming 30 minutes a day in a 20M pool.

By comparison, the Xtrainerz go longer between recharging c/w the Sony's. They are also very lightweight - you dont really know you have them on. They are however more expensive than a Sony. They also feel more flimsy than the Sony, although I haven't put the titanium to the test: with careful handling, they are probably OK.

Another reviewer makes the point that sound quality differs whether or not you are above water. I imagine that when you are submerged, you are probably increasing the amount of bone conduction(BC)? They are louder underwater, but to be honest, they are loud enough above water (and they are louder than the Sony). Yes, you can use earplugs to smooth out the difference in sound, but the real attraction of these is that you dont need to have anything stuck in your ears!

Sound quality is fine, although BC tends to favour lower frequencies, so they can sound a bit 'bassy', but again I dont think this is a problem. Music while you swim isn't a hi-fi experience, so for me they are fit for purpose.

Hope this helps and good luck with your swimming journey. Andrew

Broken within a year

Purchased these and they worked well sound is OK and overall a better solution to many I've tried when swimming. Used about twenty times until the recent lockdown. Gone to use them again and one side is not producing sound anymore. Filled out the warrenty so will see what happens with that. However it's not looking promising when the drop down menu for problems with these has my issue already to pick. Seems like a well known problem that's making me wonder if I should invest in the aeropex

Xtrainerz - excellent piece of kit

Plug in, drag and drop, hook on and press go! As well as great audio clarity and style this piece of kit is so simple to use it’s a dream (I had one of the original Sony swim MP3 players and after 12 years still can’t use it!). I am so impressed I’ve taken the time to give a review!

Chris Ryan
Great headphones

Bought these initially to get through the boredom factor or swimming. Once in the water and my ear plugs in can go for hours listening. Use them on the bike and out running as you can still hear the world around you. Had one tiny issue with them and support took care of me the next day. Great product and well worth the tiny inconvenience of having to push the files on it.
