Wireless and 100% waterproof MP3 player with Bone Conduction technology, ensuring that you can always hear the music loud and clear (without it falling out of your ear), but at the same time can hear the sounds from the outside world/coaches/swim buddies. This AfterShokz Xtrainerz in the colour Black Diamond is by far our most recommended MP3 player for swimming

The unique thing about these headsets from Aftershokz is their Bone Conduction technology, where they don't sit directly inside the ear, but instead send the music through the cheekbone, which makes it possible to both hear the music more clearly than if it were inside the ear itself, but while also being able to hear what is happening around you. It is therefore an eye-opening experience when the music plays so clearly in your ears.

This is why AfterShokz Xtrainerz is the perfect MP3 player in the water

  1. 8 hours of reliable battery life
  2. Dive down to 2 metres depth, and they will still manage complete submersion. They can tolerate being under water at this depth for two hours.. Has been tested below 50 atmospheric pressure
  3. Supports MP3, Wav, WMA, AAC and FLAC
  4. Has 4GB of memory = can hold 1.200 songs / 200 podcast episodes
  5. Full charge time in just under 2 hours = 8 hours playback
  6. Only weighs 30 grams = 20% lighter than the previous model, Titinium
  7. Surprisingly comfortable fit with body in flexible titanium
  8. Easily turn volume up and down, press pause and change tracks with a simple click of the buttons on the side of the ears
  9. Can be used outside and inside.

Apart from the MP3 player, the package also contains

  • An earplug set that you can use with the Xtrainer
  • A USB charger
  • A manual in English, that tells you in a few steps how to prepare it, put on music and use it in the water
  • A really nice water-resistant box, which can contain both the earphones themselves, the charger and the earplugs

Use the player with your swim goggles, bathing cap and earplugs

This is unique and really in demand by many users of MP3 players while swimming.

While you hear crystal clear music through your AfterShokz Xtrainerz, you can actually have swim goggles, a swimming cap AND earplugs on at the same time.

This is something that is not possible with MP3 players that sit directly inside the ears.

If earplugs are necessary when you swim, to avoid swimmer's ear, this is probably the best reason to choose Xtrainerz from AfterShokz.

The perfect MP3 player for all swimmers

As a former elite swimmer and now an exercise swimmer, I know all about the boredom of just swimming back and forth over and over and over. It just gets boring after the first four.

In addition, this AfterShokz Xtrainer waterproof MP3 player has completely changed my view on this, because with music in the ears and which is actually possible to hear and stays upside down, it just makes swimming a lot more fun.

Over the years, I've tried quite a few different types of waterproof MP3 players, but I have to join the ranks and say that these Aftershokz are clearly the best!

The sound is clearly the best on these when they go directly through the skull while you can hear your swimming buddies or the coach at the same time.

So from one swimmer to another - do yourself a favor and try these out.

*NOTE use in salt water can damage the MP3 player

The best underwater hearing phones!

Can only recommend them. I swim with them and my husband uses them for running. Nice that you can hear what happened around one, even if you hear music. Under the water, the sound stands even clearer and they work impeccably. Long battery life and easy to transfer music, etc. to those from the computer.

From desert hike to enjoyment

As very active OW swimmer with a hunger for exploring new areas, the swimming pool period has always been deeply boring. After 300m I have always hung in the rope to talk to the sideman. Now I can easily swim a few km without stopping. Really good sound, easy to operate. So there is a lot of km of music, potcasts and more.

Just works

I just swam 2 hours with Harry Potter in my ears. 5/5.

Super nice glasses at reasonable price.

Have tried many kinds, but our boy is very happy for them here. They sit well and do not tighten anywhere.
