With a compact charging case, sweatproof design, and features aimed at active and everyday users, the Duet 50 Pro targets those who value endurance and consistency over flashy extras.
The standout feature of the Duet 50 Pro is its massive battery capacity. Each earbud delivers up to 8 hours of continuous playback, while the compact charging case provides an additional 122 hours. A single USB-C charge can power a total of 130 hours of listening, making these earbuds ideal for long trips, daily workouts, or extended workweeks without frequent charging.
Equipped with dual microphones, the Duet 50 Pro handles voice calls with impressive clarity. Background noise is well-managed, allowing your voice to remain clear even in busy urban environments. This makes the earbuds suitable for walking calls, remote work, and hands-free conversations throughout the day.
Sound tuning is done at Back Bay’s Boston headquarters, where the focus is on classic American hi-fi audio. The Duet 50 Pro delivers strong bass, natural mids, and crisp highs for a full and vibrant listening experience. With support for high-quality audio reproduction, music sounds warm and detailed without overpowering vocals.
The earbuds feature an IPX5-rated nano-coating that protects them from sweat, rain, and light snow. They are designed for active use, whether during running, HIIT workouts, or outdoor training sessions. While not intended for swimming, they perform reliably in demanding conditions.
A unique advantage of the Duet 50 Pro is its ability to charge your smartphone. Using the included converter cable, the charging case can act as a backup power source for both iPhone and Android devices, adding extra utility during travel or emergencies.
With six ear tip sizes ranging from extra-small to XXL, the Duet 50 Pro ensures a secure and comfortable fit for a wide range of ear shapes. The earbuds stay firmly in place even during high-movement activities, reducing the need for constant adjustments.
