Xiaomi has just launched its new Bone Conduction Headphones 2. These feature several new enhancements, including a dedicated swimming mode and internal storage for independent music playback. Submersion in up to 5 meters of water for up to two hours is advertised.

Unlike typical speakers, these earphones do not use drivers that cause air to vibrate, thus transmitting sound using air as an intermediate medium. Instead, they use bone conduction technology, which transmits sound through the bones of the skull directly to the inner ear. In turn, this means they can be made sufficiently waterproof for use during swimming or any other kind of watersport.

Indeed, this appears to be the key feature of the Xiaomi Bone Conduction Headphones 2, namely the integration of a swimming mode. This is designed to enhance audio experience while swimming, supposedly ensuring clear sound quality underwater. Additionally, they are also said to have internal storage since connecting them to a smartphone while swimming is not really practical. A 165 mAh battery is installed, which is said to enable a battery life of up to 12 hours. 

The Xiaomi Bone Conduction Earphones 2 are currently available in China in two colors (white and black) for an introductory price of around $97. Information on a global launch is still pending.
