Product Summary

H2O has been creating waterproof products for athletes for over 15 years and continues to work on perfecting their designs with this style of Audio Sonar IPX8 Bluetooth Bone Conduction Headphones. 

With the ability to hold up under complete water submersion in up to 12 feet of water, whether you are swimming laps in the pool or surfing the waves, you can still listen to your favorite music or podcasts. 

If you are going to use the Bluetooth connection, you will have to keep your phone or device within around 3 feet of the headphones. Some athletes choose to strap their watches under their swim caps or attach them to their goggles. 

The headphones are compatible with iOS and Android products. Many reviews stated that although the sound isn’t as clear as a regular pair of headphones, it is what should be expected for listening to sound underwater. With an average of seven hours of playing time with each charge, they are great for use when doing underwater training.

      Bone-conduction technology is a great option when it comes to being able to listen to your favorite music or podcasts while underwater. These have been tested and designed by people who know what is needed for this type of training, however, there are customer complaints of the headphones glitching during use.
