Something that's always baffled me (and yes I read through the entire thread) is on one hand we have people saying the AE2 have "no bass" and other people saying that Bose products by and large have "too much bass" - makes me wonder how many people have actually taken a pair home and tried them, not a store demo, not a friend's setup on their mp3 player with 96k files on the bus, etc - but at home. This isn't meant to be confrontational - I'm just sincerely curious here. Mostly because, over the years, I've seen a lot of really ridiculous and illogical claims made about Bose and at some point I just have to ask "really?" - if you want to rip on a brand because they're popular or it lets you feel edgy, that seems fairly petty. Now of course everyone will have different frames of reference, and hear things differently, but at some point I gotta ask about consistency - most other headphones we chat about here have a fairly consistent general consensus surrounding them after enough people have heard them.
Personally I find the AE2 to be around "neutral" or "middle of the road" in terms of bass impact, but it isn't as boom-boom as the M50 or similar cans (I'd honestly put their bass response on-par with the ATH-ESW9). They're fairly smooth and pleasant sounding cans - the "+10 at 10k audiophile" hump isn't there, and they aren't analytical, dry, or sterile by any means (so people who want such cans, or want to compare them to such cans, are not in for a good time) - but they're pleasant and easy to listen to, and sound pretty good when you consider their comfort, isolation, and soundstaging as well. There's few other headphones that I would regard as being so perfect for all-day usage, and even fewer that offer legitimate isolation.
When it comes to sound quality for money - it's a tough discussion with a manufacturer like Bose (or Grado, or Sennheiser, or anyone who strictly enforces MSRP); because they're always gonna be undercut by someone who doesn't. For example, the Koss TBSE are "as good" (they're very different, but they're equally competent overall imho), and both headphones are $149 list; but the TBSE were (maybe still are) $50 at Tuesday Morning, and something like $70-$90 for most of their time on the market. So does this mean the Bose are a bad value, or the TBSE are a good value?
On the other hand, the M50 are $200 list, and I liked them less, so does this make them a bad value? Or the Bose a good value? It's a murky question. I'm guessing if Bose didn't enforce their MSRP, that $70-$100 band is where they'd sit (like the TBSE).
