Instead of going in your ears, these headphones from Aftershokz use bone conduction technology so that you can listen to music while still hearing everything from the outside world. — dpa

Many headphones tout their ability to tune out the rest of the world for good reason: Do you really want to hear that baby crying or that couple arguing on the train after a long day at work?

Thus Aftershokz's concept of wireless headphones that don't go in your ears, leaving them free to pick up on exterior sounds, elicits some rightful scepticism.
