5 out of 5 eggs

Pros: I've owned two pairs of these - I broke the first after two years of use, and bought the second for my girlfriend. Excellent fit - very comfortable, even with glasses. Doesn't require batteries to operate, unlike other brands of noise cancelling headphones. The removable cable is possibly the best part.

Cons: You have to take off one of the muffs to install the battery. Somewhat hard to clean.
