My microphone won't unmute despite following the steps

According to the G435 information, a double press on the Mute button activates the sidetone effect (you will hear your own voice). The LED indicator will blink twice in orange. If this has happened:

Press the Mute button twice again to disable the sidetone effect
Then, a single brief press will normally activate or deactivate the microphone

Also, make sure that the microphone is enabled in the settings of your device (PC, mobile, gaming console) to which you have connected the G435.
