Meet SoundSport Free headphones, the 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 achieve your personal best every time you use them.
StayHear+ Sport tips provide a secure and comfortable fit, so your headphones won’t fall out when you put your body to the test.
Sweat-and-weather resistant earbuds (with an IPX4 rating) are made with water-repellent mesh to make sure you can push your workout to its max without sacrificing performance.
Take a call, play or pause tracks, change the volume or access your phone’s Siri or your Google Assistant right from the earbud.
Custom digital signal processing and a proprietary acoustic design deliver sound—free of pops, cracks and hisses—that brings your music to life.

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 having trouble finding your earbuds? Don’t worry, an audio signal from the headphones can alert you to their location. Plus, you can manage all your Bluetooth connections, switch between devices, personalize settings and receive software updates.

This charging case protects and recharges your earbuds while you recover from your workout. It’s magnetized, 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.
