I had to force the front one that seemed to be half an inch at least, then the back one was tight. The mic is clear and I tried it on PC and an Android phone and people say I sound much better with them on. Wore them to the wedding without pantyhose. The instructions barely helped more than they hurt. Still, after a few days, they fit well. + Slots for the Move controller wrist straps. Getting choppy sound when connected to Bluetooth samsung S8 phone. Sounds great! I should have looked at the pics on Amazon. This is my last review because this product is well made and holds a lot!
