Pros: POP, R&B, especially on certain female voice..ect.
Cons: Poor on classical music which like Symphony
I own the ESW9 for just over a year with over 600+hrs run on it.
As an portable headphones, it doesnt do job well at the 1st 100hrs when i try to hook it wit my walkman up,i have to put my amp on.. but the sound become much more better after i had it run-in for 500hrs even i plug it to the sound card comes with my laptop direct..
Born to listen Japanese POP R&B female singers voice, not good on lots of Symphony.
However, you cant compare this thing with any other bigger headphone wit a decent system due to its size..
Since its better size with the great woody looking and $100 cheaper price dropped than the date it came out today, i would say go get one for yourself.
