Future Mobile Music Concept

Body

Wear it around your wrist, just like a watch. It also works as a watch.

By default, it's transparent, but when you want to make it stand out, just change the colors/patterns or use your favorite photo on the background.

The lucent screens are flexible to be transformed into a device you can put in your pocket.

Earphones

It changes your ears into a concert hall. 

Built-in microphone detects your voice (and humming).
Heart beat can also be detected with the built-in censor.
