Black Earmuffs Worn Behind The Head
These are 180s behind-the-head earmuffs (labeled 18OS) designed to warm the ears while leaving the top of the head free; the patented adjustable band sits behind the head and the collapsible frame folds for pocket storage. They are intended for daily cold-weather wear and are compatible with earbuds, glasses, hats, and most bike helmets, with recycled fabric and a soft PrimaLoft lining. User reports note they provide warmth, do not disturb hair, and remain springy over long-term use, though fit can vary for very large heads or small ears and some users consider the style less fashionable.

Long-term owner says 180s ear muffs are durable, springy, and worth the price
I have own a pair for over a year and I love them. I use them everyday and they're still springy and hold very well to my head. I can't speak in terms of money because I found mine on the ground, but I did drive 40 minutes to get them back when I left them at a coffee shop a couple of weeks ago so I say they're definitely worth whatever they're charging for them.

User prefers 180 earmuffs over hats and regular earmuffs, notes they are not fashionable
I actually prefer them over a hat or regular earmuffs. They don't mess up my hair, I find them to be warmer, plus they're not uncomfortable while listening to earplug headphones. However, I am realistic in that they're not fashionable. More of a "gets the job done, doesn't look dumb" kind of thing.
