Pros: good for hifi music..
Cons: no good for pop
had it for a month with 100+hrs on it, was bitten by my puppy T-T..
only couple impressions left are
1.this in ear needs to have a lot of runs on it in order to get better bass and sound stage.
2.wide sound stage feels like the big headphones, good for classical music
3.cant compare with any ATH's on pop music especially on j-pop at least for me..
