I want to get a pair of headphones that are both good for music/gaming and audio monitoring. Then I hear people say that closed-back headphones are better for audio monitoring while open-back headphones are better for music and such. I don't give a crap if any audio leaks, I just want a pair of headphones that sound out of this world while still sounding as realistic and life-like as possible. Is there a pair of headphones that meet this criteria that you would recommend? I don't want to spend too much more than $500. If there isn't anything that exactly meets my criteria, could someone explain what makes closed-back headphones "better" for audio monitoring?
