Using the earbuds Using the earbuds Information on the rechargeable battery, the charging process and the first use The earbuds and the charging case each have a built-in rechargeable battery. To charge the rechargeable batteries, you can use one of the following options: • the supplied USB cable, • a wireless charging station (Qi-compatible, to be ordered separately). The earbuds must be inserted into the charging case for charging.

With some wireless charging stations the charging process starts delayed.
Using the earbuds Connecting the earbuds to a Bluetooth device To be able to use the Bluetooth wireless connection, you must register both devices (earbuds and e.g. smartphone) via the device settings of your smartphone. This process is called pairing. If operation differs from the steps mentioned, also refer to the instruction manual of the Bluetooth device you are using. When you switch on the earbuds for the first time after initial charging, they automatically switch to Bluetooth pairing mode.
