I got these as a gift this Christmas and I really like them. They are very warm, and only slightly stifle sound.

Usually, I wear my hair up high, so hats are frustrating and my ears always end up very cold!

I find the fit comfortable, especially considering that I actually have a big head (I can't wear women's hats, I usually have to buy from the men's section!!)

The only downside is that after a long time wearing, behind my ears hurt - right where my glasses arms sit.

I would definitely recommend these to a friend, regardless.
