I personally think Bose is over hyped marketing.
Go to headfi.org. Lots of their information is for crazy people who spend 500 dollars on headphones, but there is a ton of information on affordable headphones. its probably the best source out there for information on headphones, speakers etc.
There are really good earbuds out there for less than 100. I use Nu-Force NE-7M and for 50 dollars they are quite good. I also have a pair of FutureSonics in ears that I love, the bass is tight and substantial in these (150).
