These ear muffs were nearly impossible to get "open"...that is, they come folded up on itself, and to unfold them to get them on, it took about 10 minutes! (really) They just snapped back into a bundle, the plastic headpiece was so stiff. Once opened up,it was a real struggle to keep them that way just to get them on my head, they kept folding up into a tight bundle again. The ear pieces are nice and warm and confortable, but the plastic headpiece is NOT! The two adjustable pieces stick into the scalp and are really uncomfortable unless you have something else on your head under it.  Plus the headpiece is smooth and slippery so it tends to slide off the head. They were inexpensive so I will not return them but they are not very user friendly, especially in the beginning when they don't want to open up and the ear pieces keep rotating around.....It was almost comical trying to just get them on my head!!!! If they came with a soft user friendly headpiece I would recommend since the ear pieces are pretty warm once you actually get them on!
