I understand you are experiencing issues with your A50. Here are a few steps you can take to attempt to remedy the issues.
Hard reset your A20 Headset by simultaneously holding down the GAME Button (Located below the volume wheel) and the EQ Mode button located below the power button. Please note: When doing the hard reset, have the headset plugged in directly to a confirmed power source, without the Base Station. Let charge for 15 minutes, then retry.
If using a gaming console (PS4/Xbox One) make sure the Transmitter is in Console Mode. Power button should be illuminating Blue on PS4 and Green on Xbox One. Check to make the switch on the side of the Transmitter is switched to “Console”.
If using a PC or computer, make sure the Transmitter is in PC Mode. Power button should be illuminating White. Check to make the switch on the side of the Transmitter is switched to “PC”.
Make sure the A20 headset and Transmitter are synced together. Simply plug the headset into the Transmitter via the Micro USB charging cable. Once synced together, you will see the LED lights on the front of the Transmitter will blink indicating it is synced and charging.
