EPOS-500 senheiser gaming headset flawless microphone

bought these headphones a year ago from blink, they retail at 40-50 on different websites I really like these headphones they are actually really good even their microphone is too tier used by streamers like bausffs. reason for selling is that their microphone is supposed to mute when u pull it upwards but it just doesn’t this flaw was there ever since I purchased it. that’s it
