"Best Under $300"5.0 starson by JBlue98
Pros: Unbelievable accuracy, detail and resolution. Really blocks out ambient noise.
Cons: If you are into big bass, you may want to go with Shure E-series instead.
Summary: Bought my first one in 2004, accidentally left it in a plane in 2006, and after an extensive research and demos, ended up buying the same model again. Truly amazing detail and accuracy, you will really hear the layers of sound that you never knew were there. It is like watching sports in HDTV for the first time.
However, if you like big bass, this may not be the best choice. While bass is very, very accurate and detailed, it can feel a bit thin. I personally prefer detail over power and this headphone is my all-time favorite among the models I have tried.
