Charging your headphones

Find out how to charge the battery in your headphones so you can use them on the go.

To charge the headphones:

  1. With the headphones off your head, connect the small end of the USB cable to the USB-C port on the left earcup. NOTE: The headphones won’t charge when they are on your head and connected to an external power source.
  2. Connect the other end to a USB-A power source such as a computer or wall charger. The headphones begin charging, and the status light glows solid amber. When the headphones are fully charged, the status light glows solid white.

Charging time

  • Allow up to 3 hours to fully charge the headphones. A full charge powers the headphones for up to 24 hours with immersive audio set to Off (up to 18 hours with immersive audio set to On).
  • When the headphone battery level is low, a 15-minute charge powers the headphones for up to 2.5 hours with immersive audio set to Off (up to 2 hours with immersive audio set to On).

Hear 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.”

NOTE: To visually check the battery, see the status light located on the left earcup.

TIP: You can also hear the battery level using a shortcut. The battery level must be set as a shortcut using the Bose app .

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.
