Peri Audio Offers Duo, An External Battery And Speaker Case

Peri Audio released anew case for the iPhone called the Duo that doubles as an external battery and speaker. It’s touted as the world’s first iPhone case that features a hi-fi speaker system and 2900mAh battery.

It boasts proprietary technologies such as a high-excursion speaker and acoustically-tuned passive radiator that pushes sound within a small package. It churns out a peak output of 4 watts and 100 decibels.

The Duo also connects via Bluetooth or Wi-Fi and because of its on-board Wi-Fi audio router, it can be used in conjunction with 64 other Duo cases for a “multi-room system” like Sonos but portable. A version for the iPhone 7 called the Duo Slim is due out in the coming months.
