Back Bay Audio spent years refining the Duet 50 earbuds to give them the richest sound quality, the longest battery life, and the most portable design. The result is a small, versatile pair of earbuds that our team personally uses in our Boston office and during our most intense workouts. 

 Extra-Long Battery Life
The small charging case can power a total of 40 hours of music on the go! The earbuds can play music for 8 hours before needing to recharge. The magnetic charging pod can power 32 more hours of music! 

 Classic American Hi-Fi Sound
Sound quality is our passion at Back Bay. We’ve dialed in the warm, vocal tone of classic American hi-fi stereo systems. Our custom-voiced preamplifier circuitry lets us emphasize bass fullness while making sure that the vocals and high notes are natural and detailed. The earbuds can reproduce CD-quality sound. 

 Strong Connection with Bluetooth 5.0
The most important factor of any true wireless (TWS) earbuds is connection strength. With Qualcomm’s wireless technology and the newest Bluetooth 5.0, we’ve created a strong seamless connection. 

 Sweatproof
The Duet 50s are peloton earbuds built for long workouts. Enjoy the freedom of a long jog or bike ride in the rain without worrying about your buds.
