 This is a smart cycle helmet with music technology. It allows you to connect with any Bluetooth-enabled cell phone or device. This helmet incorporates bone conduction technology, meaning there is no need for headphones. This helmet sends vibrations through your skull, enabling the rider to hear their music as well as the surrounding environment so you can safely listen to music on the go. With an in-built microphone placed within the chin strap, you are able to receive and answer calls.
