Not only does it have a removable built-in Bluetooth speaker to amplify your calls and music, it has a mute button, mic, and a rechargeable 1800mAh battery. You can either charge your phone or “share the power to a micro USB or Lightning device via the universal USB port.”
Due to how new this device is, there are very few reviews available, but it made quite a stir when it appeared at CES.
