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 follow-
ing options:
• the supplied USB cable,
• a wireless charging station (Qi-compatible, to be ordered sepa-
rately).
The earbuds must be inserted into the charging case for charging.
Thus, even on the go, the earbuds are always safely stored and
always 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 USB power source for at least 30 seconds. The lid
of the charging case must be closed during this process.
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. The charging
time can vary depending on the power source used and the ambient
temperature.
We recommend charging the earbuds and the charging case for a
complete charging cycle without interruption before using for the
first time.
When a USB cable connected to a power source is also connected to
the charging case or when you place the charging case on a wireless
charging station, 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).
At the end of its operational lifetime, this product with its built-in
rechargeable battery must be disposed of separately from normal
household waste. You can find more information here: > 45.
