Bluetoothbrush concept design

We all should have seen this coming from a long way off (the naming convention, not the device), where Erik Hernandez andKevin O’Leary designed a Bluetooth-powered electric toothbrush which features a handsfree headset. Dubbed the Bluetoothbrush, details still remain sketchy as to whether you’re supposed to chat with other Bluetoothbrush users in the vicinity or not. After all, having some toothpaste in your mouth isn’t exactly the most optimal time to chat, is it? The earpiece is located at the end of the handle, but where exactly is the microphone? Needless to say, the Bluetoothbrush would definitely have a certain degree of water resistance.
