Review on 🏊 IPX8 Submersible Waterproof MP3 Player Swim Headphone - Flexible Wrap-Around Style Headphones with Built-in Rechargeable Battery, USB Connection, 4GB Flash Memory & Replacement Earbuds - Pyle PSWP6BK by Joseph Stone

This is a pretty decent music player. It's easy to play music from my Mac. However, you should know that the sound quality is what you would expect from a waterproof music player, and it's as good as you really need it to be. Your head will bounce in and out of running water, so it doesn't have to be acoustically perfect. Some things to consider: 1. Make sure you put your glasses over it. This means that the back wire should go over the back of the goggle strap and the cable should run down just above your ears so that the goggle strap presses the player against your ears.2. Make sure you remove the earbuds after each session, dry the player and store it with a dry paper towel to soak up any water that may have gotten into the earbuds. If you don't, you may start your next workout with one side quieter than the other due to trapped water. I swam about 3km with them and am very happy with them. Take care of them and they will take care of you! UPDATE: After about 10 sessions with them, I got annoyed with water getting in around the earbuds. Got a set of these https://www.amazon.com/Extra-SwimActive-Silicone-Eartips-Pairs/dp/B01H668O1W and now it's back in business. Much better than OEM headphones. Pyle really should offer more earbud options, even if it's an additional purchase. UPDATE: 5 months use The player has died. It just started skipping a few tracks and then stopped playing, responding to button presses and charging. I've been pretty careful with it for the past 5 months and I've really enjoyed it. Too bad he died. I suspect it's not as "waterproof" as it should be for a swimmer. I am changing my rating from 4 to 2.
