Poor isolation is then main problem with this headphone. otherwise it is great for rap and RnB music that goes great with heavy bass.    The soundstage on these phones are wide! but the resolution falls flat a bit and you cant listen to individual instruments as much.   the top range is a bit better and there is no sibilance. 

Keeping this short as better people then i have written great reviews on this but im basically iterating what they find.   Excellent use for a mobile Rig. Sound isolation is much better than i thought. good on the train and still easy to take out quickly. can cause some hiss with my desktop rig but that is expected with the lower impedance. excellent for classical western and Indian music!   Cheers
