Upon delivery, the rechargeable batteries of the earbuds and the
charging case are in sleep mode and have to be woken up by con-
necting them to a USB power source once.

Insert the earbuds into the charging case.

Connect the USB-C cable to the charging case and to a USB
power source (> 14).

Charge the rechargeable batteries for at least 30 seconds.
The earbuds and the charging case are woken up and the
rechargeable batteries are being charged. The earbuds are now
ready for use.
We recommend charging the earbuds and the charging case
for a complete charging cycle without interruption before using

The perceived sound quality including bass performance, the best
possible noise cancellation, the best voice quality for phone calls and
a secure hold of the earbuds in the ear depends to a large extent on
the correct fit of the earbuds. Therefore, you can choose between ear
adapters and ear fins in different sizes.
▷
Test which ear adapter size and which ear fins give you the best
sound quality and the best wearing comfort.
