I got these for considerably less than what is listed currently on Amazon at a local department store. The sound quality of the headphones was surprisingly solid, with better bass than any bargain-priced earbuds out there. High end clarity was a little lacking, but still good.  Overall the sound quality was much, much better than my Apple earbuds.  The sound quality for phone calls was also incredibly good, while people I spoke to said that they could understand me just fine, although I sounded a little more muffled than usual.  So far, however, all calls I tried to test them out have been indoors, so no word on how the mic will stand up in windy conditions.

The ear warmers extend to fit your head simply by pulling on either end, and they will contract on their own to tightly fit your head. If you have a particularly large head they may not fit you perfectly, but overall the fit for me was snug and secure. During an hour long walk in windy, 20 degree weather, my ears stayed completely warm.

The cable to connect to your phone/mp3 player detaches, so you can simply use them as ear warmers when you want to.

Considering that they serve as above average ear warmers and headphones, and that they cost less than any separate items of comparable quality, these 180s are quite a bargain if you can get them at sale price.
