The Bose OE2 headphones don't quite sound like previous Bose headphones. For some, that will be a good thing, and we actually prefer the new sound, but others looking for a little more oomph may find them less appealing than the original.
Putting sound tastes aside, these are very comfortable, lightweight headphones that fit into a case half the size of the one included with $300 Bose QuietComfort 15s. When it comes to more casual, everyday-use headphones, that size and comfort is a big reason why I gave them high marks for design. In other words, you can wear these around without feeling like you've got a giant set of cans on your head.
As with most Bose products, price is often a source of debate, and many folks will ask whether these headphones are worth $150 (OE2) and $180 (OE2i), respectively. I can answer that simply by saying there are better values out there. Case in point: Theon-ear headphones. They offer similar sound, are comfortable, and can be found for less than $70 online (and they have an inline remote and microphone).
No, they aren't quite as compact as the Bose OE2s, and no, they don't fold up and stow away into as small a carrying case. Also, the fit and finish isn't quite as nice (the headphone cord doesn't detach, either). But they cost $80 to $110 less.
Take that comparison for what you will. As I said, these aren't a bargain, but they are good, comfortable headphones, and if they should break, Bose is known to be pretty good about replacing its headphones should you run into any snafus (they do have a 30-day money-back guarantee, so you can try before you totally committing to them). And on the bright side, they cost around half the price of their on-ear active noise-canceling cousins, the($350). In that sense, they're reasonably priced--for Bose, anyway.
