Bose Ultra Open Wireless Bluetooth Earbuds - Diamond

To turn on the earbuds

Open the charging case to turn on your earbuds. The status lights inside the case glow according to the charging status of each earbud. The status light on the front of the case glows according to the battery level of the case. An amber light indicates charging is needed. After removing the earbuds from the charging case, close the lid to help preserve the battery life and keep the case free of debris.

To turn off the earbuds

Place both earbuds in the charging case and close the lid. The earbuds will power off, disconnect from the Bluetooth device, and begin recharging.
