...no ambient noise? im trying to concentrate in my dorm room and i want a good pair of headphones that will drown out (at least to a degree) people blasting music and stuff like that. Should i get passive noise reducing headphones or active noise reducing headphones?
The thing about Active noise reduction is that i have heard they produce a faint high pitched whine when it is turned on but there is no ambient noise around. is this true? or am i just totally wrong? if you can give me some advice on some really good headphone models that worked for you, that would be great! thanks in advance!

if i end up buying one that was recommended to me here, ill definately give best answer!
