Review on 🏊 Waterproof Swimming MP3 Wireless Headphones with 8GB Memory, Noise Cancelling Mic - Ideal for Running, Cycling, Gym, Diving Water - Black by Mark Kolipano

I would not recommend these if you are using them for swimming as advertised. The instructions don't help you set it up for water use. I had to constantly correct them in the water. Now the right side even sounds muffled when dry. I am returning them after one use. Update: Although I tried two sizes of headphones, I tried a different one with a third option. I have the same problem. They have been returned. They might be ok for land training but then again I wouldn't recommend them for swimming (that's why I bought them).
