Waterproof Bluetooth MP3 Player for Swimming Waterproof 8GB Sports Clip Hi-Fi Sound Music Player with Waterproof Earphones Portable Bluetooth Receiver with Hands-free Calling(Black)

- Fit well- Decent Sound- Bluetooth worked IN water, NOT under.I clipped the receiver to the back of my googles strap since the back of my head is above the water most of the time. It will cut out if you submerge it but as soon as you come up it continues to play immediately. I swam for about an hour to try them out and only had them cut out for a second here and there when my head went below, a more than fair trade off for Bluetooth headphones while swimming!I loaded some mp3's on there just to try it out and didn't experience any MAJOR deminished sound quality while fully submerged and no cutout at all, which is nothing special but I've had bad luck with Pyle swimming MP3Swam about 25-30ft from my iPhone 7 and had no drop out, and out of the pool I was able to walk around my house without dropping signal either.

This worked WONDERFULLY at first. Totally went underwater and played my mp3s very clearly but this week it started tripping out. It used to turn on, say "Power on. Bluetooth Mode, wait, connected" and then you could press the M button to play the mp3s stored in the memory. It won't let me do that anymore. It just keeps cycling and shutting itself off. Doesn't pair to my phone's bluetooth anymore either. Seems like maybe it's not staying on. Had to buy a different mp3 player :(

failed first use, returned with no option of replacement

The size and the funcion is very good, nice volume ....
