Wanted for pain relief, did not get it. [SEP] So these don't work great, honestly they kept slipping off my head and they get turned around so easily I kept losing where the buttons where on the sides. The buttons also ended up being right behind my ears most of the time and wasn't really helpful in keeping my mask strings off my ears. They work good for like 10 maybe 15 mins before everything goes to heck in a handbasket and you are tugging it back into place.
