This headphone has a mediocre bass response. Very smooth,gentle mid, is like over smooth , I can even hear some background echoes. Its biggest weakness is the treble high , it is very weak and boxy  , but at least it's not harsh. Classical string instruments like violin or cello sounds not very well , piano is very fuzzy, it cannot distinguish between low and high . Bass guitar and drums are fine ,  guitar ( both electric and acoustic ) sounds very nice , according  to my previously, mid is very good . The music style I recommended that fits this headphone well are acoustic, country or old school blues . Pop,rock and roll and metal are fine . I  don't recommend classical music, it is wasting money if you use it for classical . Overall, from low to high , they are all sounds very behind , I don't know how to describe, it just too smooth. By the way this headphone already comes with adapter that use for guitar amp( I wasted 12 bucks ).
