Fantastic sport headphones

These are definitely the headphones for you if you sweat alot. They block out almost all outside noise really well so you can concentrate more on your workout and your music. The sound is so very crisp and clear with great bass without having too much. Super quickly connects to your cellphone and when you turn them on it tells you how much battery power you have left. I want to buy more pairs but now they are sold out, not surprising.
