Following up on my end, after close to a month of ownership...bottom line: I still love 'em. Great sound across the frequency range with amazing low end. Marginal - and I'm really trying to nitpick here - ambient noise, and no gripes from anyone else in the room while I'm listening to them. Both of these were a pleasant surprise, which makes me love 'em all the more. Definitely an excellent $100 investment...after making sure they're a comfortable fit for you. That was my biggest concern in doing my research, as it really seemed to be a love/hate thing.
Good luck with your decision. Audio-Technica and Sennheiser are excellent as well. I've had a long dislike with earbud type headphones, yet I picked up a Sennheiser set for my iPod that are comfortable and sound incredible. I'm amazed at how many incredible options there are now compared to (granted, many) years ago when I was last in the market.
