Pros: Very satisfactory SQ for the price
Cons: Uncomfortable when pressured against ear i.e. when lying down.
My favourite choice for using with my Sony Hi-MD Walkman & remote combos.
Value rating is for my second purchased pair, which I got for about $56 in 2008 ;) .
More detailed review when I find some more time to write here.
2012 Update: Well, lets say they sounded great for the price in the 2006-2008 period. There are certainly better options nowadays. Heck even the old ATH-CK7's have a higher resolution. Those would have been a nice alternative if their bass hadn't been too strong to my taste; the EX90's have a better tonal balance.
