The first 4 set, the chalk didn?t show well but the 2 pack it did. As long as you can position the mike and then leave it alone (dont adjust it while youre recording), youll be fine. After finding the knob for $8 I thought it was smooth sailing until there was a $15 shipping cost. I have it on my fridge to hold my teas and paper towel. I had a small issue where you could hear static feeding back when there was no activity on the mic (in between songs) and the mic wasnt picking up very loud. They have a nice gripping sole and I have taken the trash out wearing them. Cool, I have a million of those. Likes: sound quality and volume span. They are replacing a similar priced pair of Bluedio headphones, the Bluedios sounded better. Having smaller hands also helps.
