To the casual observer, Cynaps might look like an ordinary baseball cap. But flip it over, and you'll see bone conduction wiring threaded through its band. Tucked into the bill is a larger control panel with three buttons. Attached to it is another wire with a microphone. Pair the hat via Bluetooth with your phone, and you can listen to music, answer phone calls, or talk to Siri or Google Now.

Cynaps is great for people on-the-go, like when riding a bicycle or motorcycle, or any other times when you want to hear the audio and your surroundings. Because the sound is conducted through your bones, it is also a good device for people hard of hearing.
