The earphones are placed inside the ear, in the ear canal, so they do not fall out of the ears even during intense movements. The headset uses Bluetooth transmission, thanks to which it works with mobile devices equipped with this technology.

In addition, it provides constant access to power and prevents accidental discharge of the earphones.
