The first truly wireless in ear headphones from Bose, made for the toughest workouts. They are engineered to deliver clear, powerful sound with nothing—not even a single wire—in your way. So you can run, jump, dance, lift, twist, turn and achieve your personal best every time you use them.Worried about losing an earbud. Don't be. The Bose Connect app has a 'Find My Buds' feature that tracks when and where your headphones were last connected to your phone. Still can’t find them. An audio signal from the headphones can alert you to their location. Plus, you can manage all your Bluetooth connexions, switch between devices, personalise settings and receive software updates.This charging case protects and recharges your earbuds while you recover from your workout. It’s magnetised, so it keeps them in place while they charge. It also provides two additional full charges—or up to 10 hours of battery life. So when you’re ready to go, your headphones are, too.
