Setup
1. Initial Charging
Before first use, ensure both earbuds and the charging case are fully charged.
- Remove Protective Film: Important: Before charging, remove the thin protective film from the charging contacts on the earbuds. Failure to do so will prevent charging.
- Place the earbuds into the charging case.
- Connect the USB charging cable to the charging port on the case and to a power source.
- The indicator lights on the case will show the charging status. A full charge typically takes approximately 1.5-2 hours.

- On your device (smartphone, tablet, etc.), enable Bluetooth.
- Search for "Monster Earbuds" (or similar name) in the list of available Bluetooth devices.
- Select the device name to connect. Once connected, the indicator light on the earbuds will stop flashing.
