SoundSport Free wireless headphones

Off a single charge, the earbuds play for up to five hours—long enough to power you through almost any workout. And when you’re done, place them in their case to recover. It’ll keep them protected, and provides two additional full charges (or up to 10 hours of battery life) to keep them ready to go again. Plus, a quick 15-minute charge will give you 45 minutes of battery.
