Charging your headphones | SoundLink® around-ear headphones
To charge the battery:
Note: The Bluetooth® module will not work while charging.
- Power off your product
- Connect a USB cable from the Bluetooth module to a USB charger. The battery light blinks amber while charging and glows solid green when charged.
Note: Typically, the battery will fully charge in about 3 hours; this varies depending on the charge level and the charger used.
There is a Youtube video for these instructions.
Plugging in overnight will not overcharge the battery
Lithium batteries have a built-in auto-off feature when a full charge is reached to prevent the battery from being overcharged. Even while still plugged in, the battery level will have to drop below a certain point to trigger the charging again.
