Noise cancellation awesome, not enough bass

All that being said, as much as I love these headphones I think I may have to return them. They are great for casual listening but aren't very useful in a studio recording / tracking situation. The sound is too colored (not flat). So the only use I can see these for is personal enjoyment in the office, which I can't justify the 300 price tag for.

Also, I light to travel lightly. These headphones come with a very nice case, but I cannot see carrying this around with me everywhere I go. Feels almost like an old oversized portable Sony Discman case.

The mandatory need for battery power provided or the headphones do not operate at all also isn't my style.

I should also mention that these headphones DO bleed. Meaning, if someone was sitting near you and you had the volume turned up I'd say halfway, they will probably hear what you are listening to. Full volume and everyone will be jamming to your tunes. You usually won't have to turn them up high though with the noise canceling, but headphone bleed is a BIG no no for me. I don't like hearing other people's headphones so I wouldn't expect anyone to have to listen to mine.

I'd say if I didn't already own a bazillion other headphones and the BOSE QuietComfort 15's offered a useful role in my recording studio other than blocking out the computer sound then I consider keeping them and if they didn't absolutely require battery power I would more than likely keep them. But 300 just for personal use to block out office noises that are fairly blocked out with the use of ear buds I cannot justify.

Maybe if I run into an exuberant amount of cash flow in the future I may repurchase. Hopefully by then they will have a model that operates even without battery power. =)

First of all the pros:
1. Noise Cancellation very effective.
2. Sound quality is good, but I think it could have more deep bass and a better treble.
3. Very comfortable

Now the cons:
1. The design is ok. But when I use it, if I change my position of head or move my mouth (eating) at high volume, the phone distorts. I need to find the best fit for the ears and don't move. I feel that I need more pressure against head to avoid this.
2. The material looks cheap (like U$100 headphones)
3. It could have a volume control in body.
4. The headphone works only with batteries and the Noise Cancellation on. You could have the option to turn on/off the NC.
5. Very expensive.
6. The cables are very thin. I don't know if they are going to survive more than a year
