microphone quality

Hello there!

first of all thank you for this great review.

I have a question about the quality of the microphone. Was the headset connected to a PC or laptop during the sound test above and was an internal or external sound card used?

I have the problem that the microphone does not sound good on the PS4 or on my laptop. This is what my colleagues in Discord have told me clearly.

Do I have to change anything in the sound settings in Windows or what could be the reason?
