First, bone conduction headphones have to fit tightly on your head in order to transmit sound clearly. The pressure and chafing becomes uncomfortable over time. If your helmet feels comfortable, Ahead will feel comfortable.
Second, most bone conduction headphones sit at exactly the same line as bicycle helmets and above the line where you wear larger helmets for motorcycles, snowboarding and other sports. Ahead is designed specifically for use with a helmet.
Finally, bone conduction headphones lack Ahead’s beam-forming voice capture technology, which filters out ambient noise and wind noise, so you can be heard clearly at up to 60Km/h(40 mph.)
