Rating : - Won't get on a plane again without them.
Decided to invest in a pair of noise cancelling headphones. I first tried an inexpensive pair of Sony's and loved the noise cancelling, but they were uncomfortable (on ear style). I did some research and found the NC60s.

Pros:
- Over ear is extremly comfortable. I wore them from Atlanta to LA non-stop with no discomfort at all.
- The weight doesn't seem to bother me as they are all well padded.
- The detachable cord is awesome. Can keep them on and walk around without the cord. Also you can unhook them for landing and the flight attendants will leave you alone (at least they have for me).
- I'm not a true music person so to me they sound pretty good. Great to be able to hear the movie without having to crank the volume.
- The monitor button is handy for hearing announcements etc.
- Case fits all the accessories and an Ipod shuffle, but will have to store anything bigger somewhere else.
- Good battery life: got 13 hours or so out of battery supplied with headphones.

Cons
- Get some buzzing occassionally but if you readjust the headset it goes away. Seems to only occur when you don't have any source going to the headphones.
- No warning for low battery. You start to get buzzing and one side will stop cancelling etc. I started to get nervous until I realized how long I had been wearing them. Changed the battery and good as new.

Compared to the price of the Bose, these are a steal at $200 and even better at the $130 or so Amazon has them. I got lucky and didn't get a pair of the bad ones. I'm hooked and even on short flights I bring them along.
