Charging your headphones | SoundLink® around-ear wireless headphones II

To charge the battery:

Note: Bluetooth® cannot be used while charging.
  1. Power off you product
  2. On the bottom of the right earcup, connect a USB cable from the product to a USB charger. The battery light blinks amber while charging and glows solid green when charged.
Typically, the battery will fully charge in about three hours; this varies depending on the charge level and the charger used.

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.
