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. "

No Spotify or Apple Music compatibility

Very disappointed that it was not made obvious that you are unable to use Spotify or Apple Music to transfer songs to headphones as these platforms don’t allow you to convert to mp3 especially when these are the two most common platforms for music in this day and age.
Seems to be incredibly difficult to be able to transfer songs from computer to headphones and very little instructions to do so from the company themselves. Very disappointed after being very impressed with my other shokz headphones I use for cycling…
