"Wireless Earphones" is a system app that allows you to manage your OPPO and OnePlus earbuds. After connecting your earbuds, you can view the battery levels of both earbuds and the charging case in real time. This app also offers functions such as sound effect adjustment, gesture customization, and firmware OTA updates.

You cannot open this app directly. To use it, follow these steps:

After pairing your earbuds with your phone, tap "Settings" in the pop-up window to access the earbud function list. Alternatively, go to "Settings - Bluetooth" on your phone, tap your earbuds' name, and then tap "Earbud functions" to enter the earbud function list.
