Get 120% more life from your iPhone, with the 2900 mAh battery – that's 60 hours of music, 13 hours of HD video or 16 hours of talk time!
Stream music wirelessly via Bluetooth or Wi-Fi. Use Duo's on-board Wi-Fi audio router to stream high-resolution, lossless audio files with 100% clarity. Or Connect up to 64 Duo devices over Wi-Fi with Quick Link PERI’s technology!
Save and Play your favorite Spotify playlist from the cloud with PERI’s Quick Play™ one-button streaming while the Duo is detached and connected to your home Wi-Fi.
