Comfortable.  And they work.
I bought these and went to a local show.  I wore these all night ,and actually forgot i had them in.  I could still hear the music clearly at a reduced volume.  I also like the handy carrying case... very convenient.  Just get a pair, you won't regret it!<br /><br />edit:  I'm also finding when I'm in a very noisy environment like a restaurant, i can put them in to drown out and the background noise nicely.
