The bone conduction design of this new Cleyver Open ear UC model allows users to enjoy exceptional comfort without losing sight of their surroundings, as this patented technology does not overload the user's ears for sound transmission. The wireless headphones emit sound vibrations through the user's cheekbones, allowing sound to reach their ears directly without passing through the eardrum. The Open ear earphones' light weight of 40 g ensures that you can wear them comfortably without experiencing any irritation.
