During bike riding, it’s too much complicated to receive a call. Some time you have to miss some important calls also because of crowd or traffic. We have resolved this problem by developing Bluetooth helmet. Just connect your helmet with your Bluetooth device and your Bluetooth helmet will be ready to play all the functions of it. If anyone calls you, helmet will announce the callers number, if you think that the call is not important, you can disconnect it from the given button in the helmet.
