Charging the battery
Charging headphones in the charging case
A rechargeable battery is built into the charging case. If you have charged the charging case, you can charge the
headphones without using the USB charging cable.
• If the rechargeable battery power is running low, the product will beep through the headphones, and the indicator
lamps of the headphones will flash in red. When these beeps sound, charge the battery.
1. Place the headphones in the charging case.
2. Close the charging case cover, and start charging.
• During charging, the two charging indicator lamps (for the headphones) light at
the front of the charging case. *
* For indicator lighting, see "Charging the headphones and charging case" (p.6). Also, if
the charging case is fully discharged, the charging indicator lamps do not light even when
the headphones are placed in the charging case.
