ZAGG Bluetooth Case
This is one of the coolest iPhone cases I've ever featured here on Unbox Therapy. The ZAGG Bluetooth case includes a battery, bluetooth speaker and microphone. It'll extend the life of your iPhone or boost up your tunes while riding along like a backpack.
The ZAGG Speaker Case is a protective case that features a removable, wireless Bluetooth speaker that's perfect for boosting music, conference calls, videos, and games. It also has a built-in battery that powers the speaker and provides up to 1800mAh backup power to the phone. Use this power on your own or share it via the built-in USB outlet. Amazing sound and portable power have never been easier.
