I bought these as a replacement for the 180s I purchased last year and lost recently.  We just had a cold spell with weather in the upper teens all week.  I have a 1/2 mile walk from the train station to work and same on the way back.  With the 180s on, the biting cold didn't bother me so much and did a great job keeping my ears warm.  A must have for that kind of weather.

Compared to my last pair, this pair seemed to fit a little tighter, slightly uncomfortable when you put them on at first but not bad.  If amazon gave half-star ratings, this would be a 4 1/2.
