To use the BOSEbuild Headphones, the battery must be charged using the USB cable provided in the box.
Charging your headphones
Applies to:
Plug the small end of the USB cable into the micro-USB connector on the right earcup
Plug the other end into a USB wall charger or computer that is powered on. During charging, the battery light blinks Amber. When the battery is fully charged, the battery light glows Green
Charging time
Allow up to two hours to fully charge the headphones. A full charge powers the headphones for up to 15 hours of music listening, or up to 8 hours of music listening with LED lights.
Listening to music at high volume levels or using the LEDs at full brightness draws battery power more quickly.
