Bose.......blows. Overpriced no matter the model. Same goes for Shures. You do not need to pay Bose prices for what you can get in a $40 speaker model.
I shopped around A LOT before actually choosing the Bose headphones. I bought several similarly priced headphones and Bose were the best (and yes that did include Sennheisers). Trying 6 different models, the Bose was the best. It was of much better quality than the other models, the sound was unsurpassed, and the on-ear design is the best thing I've ever seen (or heard I should say). I've owned $5 headphones, $10 headphones, $20 headphones, $30 headphones, $50 headphones, $100 headphones, $200 headphones, and even a $350 pair of headphones and my $200 Bose headphones is the best of all of them.
I also own the $750 surround sound system from Bose and it's the best. I don't know where you got your information, but it's majorly faulty. I'm sorry but you can't get the same quality from a piece of crap $40 pair of headphones than you can from my $200 Bose. Believe me, I've tried (I'm cheap and I tried EVERYTHING not to have to pay $200 for a pair of stupid headphones). I'm thinking of studying audio engineering in college and the professor was downright amazed by the quality of my Bose. I may not know everything about audio that I'd like to, but Bose is a very good brand. I just can't get over how good they sound. My Bose headphones totally blew away my previous pair (a $50 Sennheiser) and the others I tried of similar price. They were worth every penny and with a complimentary 3-year warranty, I know they stand behind their work. I can't say that much about some of the other headphone brands out there, even the more expensive ones as they only give out a 1-year warranty.
Bose may be expensive, but they're worth it. Yeah, there are better brands out there but Bose is great if you're on a budget. I admit that some Bose products are a bit insane (such as their $800 wireless headphone set. It didn't sound any better than the $200 so you were basically paying $600 to not have a cord). Let me put it this way...I can't listen to any MP3 unless it's 320kps. It sounds like s*** if it's any less. I can tell you exactly how many kps a song is just by hearing it with my Bose (though I frequently mix up 128kps and 196kps since they're so close). My previous surround sound system could blow you out of this world, but once I got my Bose, I gave my previous surround sound system to my aunt.
Bose may have been overpriced years ago (I don't know. I didn't care that much about how good of sound I got back then), but from what I can tell in recent years, they really deserve every penny for their products.
Oh, and one Bose product that I would stick away from is the $250 pair of computer speakers. They really suck. Heck, my logitec speakers beat them.

I returned those the same day.
