The bracelet which is called e-mobile can also be used to play MP3 music and be connected to headphones (no Bluetooth support was mentioned but it could surly be useful with such a device). The bottoms of the e-mobile are shaped like diamonds which adds to the fashionable look of the device.
The one big flaw we see in this concept is the lack of a screen which might have been incorporated into the internal or side of the bracelet to show the number of the person calling ad the number dialed.
