Do you use the coming mic or use the built-in mic of your headphone? If you want to use your headphones’ built-in mic, double click the Multi-Function Button on the C81 and enter talk mode. The sound quality will be limited in this mode. This is due to current Bluetooth technology restraints. You could check the above video for how to set the sound setting of the PS5 too.
