NTT DoCoMo's Sound Leaf, a cell phone accessory that uses bone conduction so that those who have hearing deficiencies or are in loud environments can hear cell phone conversations more clearly.

The SoundLeaf can be paired with any cell phone using Bluetooth. This phone, unlike the rest pictured here, is an actual product, already on the market in Japan.
