Wireless earbuds with extended battery

The Back Bay Audio Duet 50 Pro are sweatproof true wireless earbuds built for runners and daily commuters who need days of playback without hunting for a socket. They deliver eight hours of continuous listening per charge and come with a compact case that stores an additional 122 hours. A single USB-C charge of the case yields 130 total hours of music or talk time.

Replaces daily-charge earbuds

The jump is worth it when you regularly forget to top up overnight or take multi-day trips where power outlets are scarce. Dual microphones handle clear phone calls and voice commands on both iPhone and Android. IPX5-rated nano-coating protects the buds from heavy sweat, rain and snow, though they are not rated for swimming.

Fits in a pocket and powers your phone

The mini charging case slides into a small pocket or running belt and recharges via the supplied USB-C cable. An included converter cable lets the case act as a power bank for any iPhone or Android device. Buyers who need on-ear controls, active noise cancellation or waterproof submersion rating should look elsewhere.
