These headphones have powerful bass (comes with a lot of ommph) which is good and lets honest if your interested in these earphones main reason will be for the bass 
 
For listening to music such as Pop and dubstep these are very good as the beat/bass just comes alive.
For rock I found them good but not excellent.
For classical and new age music its OK I found them a little too fun and bright and somewhat disorientates the presentation. 
Jazz and blues again I find them OK but there's sometimes too much bass and affect the song overall negatively.
 
All in all fun headphones and if you mainly listen to Pop and Dubstep (or anything bass heavy) then these are perfect.
