I've had 2 other pairs of 180s, which unfortunately seem to get lost.  The older ones (180s Degrees) had a stretchy, fleece-like outer shell.  This allowed the round ear coverings to cup over my ears, and they were quite comfortable.  The outer shell on these is not stretchy.  It's like being squeezed between two small ping pong paddles.  The outcome is twofold:
1) They are less comfortable and exert more pressure on my ears
2) They are less warm, as they don't seal very well

Perhaps it's a head/ear size thing, but these are not good for me.  I'll be ordering a pair of Degrees instead.
