   NOTE: The headphones don’t play and aren’t available in the Bose app while charging.

 

Charging time

Allow up to 2.5 hours to fully charge the headphones. A full charge powers the headphones for up to 24 hours.

Hearing the battery level

Each time you power on the headphones, a voice prompt announces the battery level. When the headphone battery is low, you hear “Battery low.” To visually check the battery, see the status light located on the right earcup

リチウム電池には、満充電になると過充電を防ぐための自動停止機能が組み込まれています。充電器に接続されたままでも、バッテリー残量が一定のレベルを下回るまで充電は再開されません。
