The world’s first complete wireless bone conduction earphone earsopen PEACE TW-1 solves common problems of the conventional earphones such as risk of hearing loss. Sound is delivered via bone conduction instead of blocking the ear canal, while making it safer as the surrounding noises are still allowed through providing greater situation awareness. Designed to be clipped onto the lower part of the ear, it offers an excellent fit while making it hard to drop so that you can enjoy quality audio and comfort anytime and anywhere. Not only the earphones deliver an excellent comfort even when sweating, but they are also so lightweight, only 9g, that you even forget you are wearing them.
