The Ear Muff Headphones have integrated headphones, which are removable should you just want the ear muffs.
The ear muffs are available in quilted, fleece (great for guys) or fur fabric, each in a different color. They retail for $30.
We think it's a smart idea to have these if your climate dictates them, and the behind the neck construction means your hair style won't get messed up if you're wearing these to somewhere.
PS We'd need earmuffs, too, if we were dressed like that!
