Well, ok there are a few things I'd like to add.
I've commented on a number of posts about bose overall, and having owned the triports (which is probably more than I can say for most others who bash bose) and have used the Quiet Comfort 3s, that I have experience with what bose is actually good at (and yes, they do have some decent qualities.
Bose headphones, when others who don't know headphones look at them, they automatically think "oh wow, that guy is rich" or "oh wow, this guy really is into music". It's a status thing that Bose brings to the table. Simply, the bose products do look good. Both the Triports and the QC3s are excellent looking products, hands down in my opinion.
Now, to those people who've only listened to bose outside say the normal earbuds that came with the ipod, the bose sounds darned good. I know when I first got my triports, I was amazed with the sound, and seriously thought it was the best thing on earth. Only after listening to other headphones have I really noticed that maybe the bose aren't quite so good after all.
So, the sound quality. After listening to Beyerdynamics for only a month and a half or so, after using the triports for over a year, I can no longer stand the triports for sound quality. Both my Beyerdynamic 880s and my A900s beat out the triports without any problems.
As I mentioned earlier, though, Bose does have some nice qualities:
1. They look good, very good.
2. To the semi-untrained ear, they sound fantastic, you can't get better (from the perspective of the normal consumer).
3. They are small. My largest beef with the headphones I normally listen to, they are huge and heavy. I don't mind them when I'm by the computer, but they can't travel worth anything. I know other headphones exist, but at this point I want my sound quality everywhere, getting cheaper portable headphones that actually are portable won't sound as good on my music now, haha.
I don't think bose is worth the money to spend on their headphones. The triports do beat out the QC3s in sound quality in my opinion, and the triports lose to near everything else. Placebo effect or not, my visit to the forums, and my plunge for new headphones have given me a lot better music. Through various pieces that are well mastered, I can hear the individual chime bells so clearly, where I couldn't hear them as clear or clear at all with the bose (I know because tonight I just messed around with both headphones, using the same source and was astounded by the feeling).
I don't want to bash bose, nor will. Basically if a pair of headphones sounds good to you, then use them. The name brand doesn't really mean a whole lot when it comes to sound quality in this case. Try out multiple types, and if you still like bose after all that, then that's good
