5 out of 5 eggs

Pros: very comfortable for long periods of use, compact size for travel, works well at reducing engine noise on transatlantic flight when seated over wing (doesn't eliminate all noise, but makes it very tolerable), good at blocking voices and construction noise, enhances sound quality when noise cancelling turned on

Cons: exterior battery/cancelling unit sometimes a little awkward, but the resulting performance is worth this minor inconvenience

Other Thoughts: This product exceeded my expectations! Worth the price.

5 out of 5 eggsGreat headphones

Pros: Great Sound. Very Comfortable. Very Portable, ie they fold up. Noise cancellation also amplifies the signal. Helps make ipod a little louder. Also comes with 1/8th inch adapter and airplane adapter, which comes in handy.

Cons: Exterior battery container/noisecancelling.

Other Thoughts: Great for trips or sitting at your computer. I might not want to cruise around the city with it, as the external case might get in the way, but you'll probably have a backpack if your using your ipod/mp3 player.

4 out of 5 eggsComfortable, Compact, & Sound Great

Pros: Compact size compared to rival products. Nice case. Includes adapter for airplanes that still use the dual prong plugs. Very comfortable.

Cons: None yet

Other Thoughts: I have some noise isolating ear buds from Shure which work great. These are much more comfortable to wear for long periods of time (long flights). I just used these on the plane and they worked very well. The noise canceling takes the engine noise down quite a bit. I will say that you can still hear some noise, if you don't have anything being played from the headphones. I am very happy with these.
