This is a pair of AfterShokz Aeropex bone conduction headphones. I purchased them about 5 years ago, but only used them for about six months. There are scratches and dirt from use and storage. Please consider them as junk items due to the long period of disuse. Functionality has been confirmed. These lightweight and comfortable bone conduction headphones allow you to enjoy music while still being aware of your surroundings, even during exercise. - Brand: AFTERSHOKZ - Type: Bone Conduction Headphones - Color: Black - Accessories: Pouch, charging cable
