Review on 🏊 Swim in Harmony with H2O Audio Sonar - Underwater Waterproof Headphones with MP3 and Bluetooth by Enrique Espinoza

I used them for the first time today. They worked great. It has breathed new life into my swim training. The only issue I had was that I was using it with my Apple Watch and the audio cut out when the watch was submerged in water. I'm assuming this is an issue on the side of the watch and/or the bluetooth signal not being able to get through the water. On a freestyle shot, the audio would carry when my hand was out of the water, but once it was in the water the audio would cut out. Luckily you can download music straight to the headset so I have music for my next swim. The music preinstalled in the headset is a bit quiet and not very motivating for training. The first time I use them I really like them. They were easy to use and easily attached to glasses. They didn't slip, they sat firmly on my head. The sound quality is excellent. I've read other reviews about concerns about how loud they play and that others might hear your music. It's noisy but doesn't travel far so it definitely won't bother others.
