iLoloCiLoloC, they are open backed headphones so they will not have very good sound isolation, in or out. You can probably hear people around you pretty easily, and people around you can hear your music pretty easily.
some_chordswell i have got open back sony mdr 900, which have holes in the cups, so i should hear even more backround sound, but not, when i crank the volume up, i at least don't hear my neighbours behind my room entrance doors, what they are doing in coridors, and what music they are playing through their speakers below or around my flat
