Can Hear Through Headset But Can't Talk PS4?

After unplugging your headset from your PS4 controller, detach the mic boom by pulling it straight out of the headset. Finally, reconnect the mic boom by plugging it back into the headset. After that, insert your headset back into the PS4 controller where it originally was. 2) Use the headset with the microphone that came with your PS4 with another device to test whether or not it functions properly.
