I currently have an O2 and a K702, which I really enjoy the sound of. But I can pretty much only use these when I'm alone as it leaks plenty of sound.
Thus, I am now in the market for a pair of headphones that don't leak as much sound (to not annoy my roommates).
I will be using it for gaming and music, 50/50. As for types of music, I listen to pretty much all music except for the heavy metal type stuff.
I will probably be willing to spend up to about $200 for either IEM or over ear closed back, as long as the sound isolation is good :).
Thanks for taking the time to help me out!
