H2O Audio Interval Waterproof Swimming Headphones for Apple Watch – Bluetooth IPX8 Underwater Sports Earbuds with Bass-Amplified Surge S+, 6-Hour Playtime: desertcart.co.uk: Everything Else

Review: H2O bone conducting headset - I originally (~1 year ago) purchased the H2O interval in ear headphone set; unfortunately it only worked for two weeks and developed a fault. The left channel ear plug was hardly audible, whilst the right channel is normal volume. I recently purchased the h2o bone conducting headset and have been very pleased with them over the last 3 months. They work very well connected to my Apple Watch and have proved totally waterproof down to swimming pool depths. They are used every day. The sound in the water is very clear.
Review: Possible faulty product - Tried to use 3 times, would work fine on dry land, however first swim the earbuds kept falling out of my ears, so had to keep putting them back in. Thought, I probably just need to size up on the ear tips. Music played okay during that first swim. Anyway, tried the bigger ear tips, next swim they stayed in much better however halfway through the swim the headphones seemed to just die, and couldn’t turn them back on at all. This despite the battery being at 100%. At home, tried to use them and they worked okay on dry land again. 3rd time, they wouldn’t even turn on, this was before I got into the pool. I’m hoping this was just a faulty item. I’ve returned them to desertcart, will try reordering them but if those still don’t work then it’s not for me sadly.

### ⭐⭐⭐⭐ Easy to use
*by K***R on 20 August 2023*

This is my second H2O. My first one refused to charge after just over a year. Amazon gave me a full refund. prefer in ear phones so that I do not need to use ear plugs. I do not like water in my ears. Very stable in terms of output. To prevent track jumping I place the H2O on the top of my head when I am doing crawl or back stroke.
