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. The charging case allows you to store the earbuds safely at
all times while they are being charged.
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 power source once. Sennheiser recommends
charging the earbuds and the charging case for a complete charging
cycle without interruption before using for the first time.
A complete charging cycle of the charging case and the earbuds
takes about 1.5 hours. The quick charge function gives you approx. 1
hour of playback time after 10 minutes of charging.
Sennheiser recommends using the supplied USB cable and a com-
patible standard USB power supply for charging the headphones.
When a USB cable connected to a power source is also connected 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 charge status (>
8).
When the battery charge of the earbuds drops to a critical level, a
voice prompt asks you to recharge the earbuds (“Recharge head
-
set”).
The charge status of the rechargeable battery of the charging case
is displayed by the LED on the charging case (>
8).
