so cool on hot summer days . As others have noted they fit on the small side. Absolutely love them there perfect. So I took a small piece of 400 grit fine sandpaper and gently rubbed the rough edges off. At this price, it is useful to have these available on occasions where regular headphones are simply too opaque for safety and awareness reasons. And if you?re not super careful when pulling them out (or if your cat suddenly goes mega spastic and knocks the whole darn thing over in the process of trying to hurl it?s body towards the nearest exit simply because you accidentally dropped a plastic hanger on your solid surface flooring causing an unexpected loudish noise), you?ll scuff up the leather or fabric covering on the heel portion pretty bad. I like that there is backing behind the buttons. All the other ones have taken from 30 minutes to an hour, so that was amazing to me. My students love them and are excited to get to keep them. Please, refund me and take them back!
