The iPhone is already a pretty decent device to listen to music and make phone calls. The Amp case aims to take your experience to the next level with its 2 speakers. This sound system slides onto your phone and enhances its audio quality. Amp is quite smart. It actively measures the noise around you and uses dynamic noise reduction to allow you to enjoy your music anywhere. It also learns from your music preferences.
The Amp case has 2 14×20 mm drivers. Amp plays audio for 7 hours over its speakers and 20 hours over headphones. The battery can even charge your phone (provides up to 25% more battery life for your phone). Its audio processing engine runs on a Cortex-M4. The case will be available in black or white. You can get yours for as low as 69.[Source]
