Benefits
- Enhanced stability
- Power through the day
- Worry-free wearing
You’re constantly moving, but your earbuds shouldn’t be. With secure-fit earloops, patent-pending eartips with stabilizers and a 2-in-1 stability clip that can be attached to your shirt or used as a cinch, BackBeat FIT 350 is designed to stay in place during even your most rigorous training sessions.
Wherever you go, keep the music playing. From your morning workout to your mid-day errands, enjoy up to six hours of wireless listening and get up to one hour with a 15-minute quick charge.
BackBeat FIT 350 features a sweatproof and IPX5-rated water-resistant design, with a sport-weave cable that minimizes friction by sliding smoothly over skin during your most intense workouts. That means you can listen to your favorite songs anytime, anywhere – even in rain and humidity.
