Wireless earphones: with Dual Leader you can also use them individually in mono

Dual Leader technology allows you to use just one earphone while the other is charging or simply placed in the charging case; the TWS True Wireless Stereo earphones boast this particular feature: each earphone is in fact equipped with a built-in microphone and multifunction buttons.

In this way, the single earphone is able to handle both music and calls in mono mode. Headphones equipped with this system will allow you to save battery life .
