With these headphones, you can listen to your favorite music while exercising. These sports headphones are water-resistant, so they don't break due to water damage. This allows you to train outside in the rain, but also inside the gym. Even the most intense workout isn't a problem for the headphones. The water resistance is measured with an IPX certification. The higher the number after the X, the better it is resistant to water. From IPX7, headphones are waterproof.
