Just standard cheap foam for earpiece. I had to size down to a 7, normally a 7 1/2, and they are slightly big but I think a 6 would’ve been too small . The posture control is very NICE! One still works so he now uses that one. 😜 Was kind of annoying putting together but wasnt too bad at all! balanced mids and highs. Volume control is terrible. I live off reviews when purchasing form the internet so I hope my review gives you some comfort in making this purchase. They do fit kinda half on ear half off, because there is an inward slant that goes towards the inside of the cup.
