What are Ear-Free Headphones?


AMA BonELF X are wireless headphones that do not cover the ears. Audio is transmitted to the inner ear using bone conduction technology, keeping the user’s ears free to listen to the world around them. Whether driving, cycling or running, with BonELF X Ear-Free Headphones, users can enjoy their audio content while still being aware of their surroundings.

BonELF X Ear-Free Headphones use bone conduction technology to deliver audio to the listener. Sound waves are transmitted as vibrations that are sent through the skull and into the inner ear, bypassing the ear canal. This enables the user to listen to audio content without covering their ears.

Currently, in the USA, it is illegal in many states to use audio devices that cover your ears when operating a vehicle. Regular earphones block the ear canals, making it difficult to hear external sounds, like car horns and sirens.


If you are driving or cycling, not being able to hear the traffic around you, could cause an accident. Using BonELF X Ear-Free Headphones, you will not have this problem, as they do not cover your ears.
