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. "

Absolutely fantastic. The quality they offer in the swimming pool is incredible and worn with the ear buds give even better sound. They are so comfortable as they sit on the side of the ear and not inside, they are great for me as swimming up and down a pool isn't a great motivation for me, but having my music playing is a game changer. Love them.

I’ve owned two pairs of these now in 3 years. They are a superb fit for swimming and running. The sound is always clear and the battery life is excellent. The main issue is that after a while the sound in one of the ear pieces doesn’t work, then the cable piece start to gradually come loose until it eventually falls off. It looks glued on and the glue wears off.
The first set that broke, I thought it was my fault for not keeping them in the case whilst in my bag, so I purchased another identical set, however I’ve treated the second pair like china and it’s happened again. This must be a design fault with the swim pro. It’s such a shame as they are awesome headphones. Shokz Customer support so far, have been very slow to deal with my complaint and it’s still within warranty. I’ve not been offered a replacement and reluctant to buy another set.

I find these headphones too complicated. Can’t work out how to put music on?

Love my new OpenSwim headphones. I use them for my regular swim sessions and absolutely love them. I spent a while uploading music from my Apple Music playlists via my computer, and there's lots of storage so I have a huge variety of music to listen to. Next up is trying out downloading some favorite podcasts too. I find them easy to put on, they stay on amazingly well (so much better than my in-ear phones which always fall out on my runs). Music quality is great, and my workouts just fly by - the grind of a swim when you're not in the mood is a thing of the past. Highly recommend.

I recently bought the open water version for swimming indoors and outdoors. They work so well, clear sound with great bass quality and easy to use buttons which take about 2 mins to get the hang of. The supplied ear plugs make the sound quality even better. Transferring music is so simple and fast. I really like the shuffle function to mix up my playlists and vary the swimming experience. Really recommend these and I have tried a lot of swimming headphones!
