To power ON your MG20 Wireless Gaming Headphones, press and hold the ON/OFF button (>1 second).
The Battery Level will be displayed by the indicator light at startup. A high battery level is indicated with a green LED, medium with an orange LED, and a red LED to indicate that the MG20's battery is low and should be recharged.
When you first open your new headphones, and before listening, please be sure to charge them for at least 15 minutes and download the M&D Connect App to check for firmware updates.
Your MG20 Wireless Gaming Headphones will enter sleep mode after 10 minutes of inactivity.
