Using the earphones
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. The charging case allows you to store your earphones safely
at all times while they are being charged.
Upon delivery, the rechargeable batteries of the earphones and the
charging case are in sleep mode and have to be woken up by con-
necting them to a power source once. Sennheiser recommends
charging the earphones and the charging case for a complete
charging cycle without interruption before using them for the first
time.
A complete charging cycle of the charging case and the earphones
takes about 1.5 hours. A charging time of approx ## minutes gives
you 1 hour of listening time with the earphones.
Sennheiser recommends using the supplied USB cable and a com-
patible standard USB power supply unit for charging the head-
phones.
When a USB cable which is connected to a power source is also con-
nected to the charging case, the rechargeable battery of the
charging case is being charged. When the earbuds are inserted into
the charging case, their rechargeable batteries are being charged at
the same time. The LED of the charging case displays the charging
process (see page 7).
When the battery charge drops to a critical level, a voice prompt asks
you to recharge the earphones (“Recharge headset“).
The charge status of the rechargeable battery of the charging case
is displayed by the LED on the charging case (see page 7).

earbuds and the charging case

The earbuds are magnetically pulled into the charging compart-
ment.
2. Connect the USB-C connector of the USB cable to the USB-C socket

3. Connect the USB-A connector to a corresponding socket of a char-

Make sure that the charging case is connected the power supply sys-
tem.
