Ok time for next query. Closed, open and ( for me unknown until today ) half-open back. Talking about Studio (HP) headphones. I have always used closed back HPs. But recently one of my friends told me that U do have to use open back to hear the stereo information. I do not use headphones to hear that, I do use headphones to isolate what in a track i don't like (over and over on repeat). But it maybe sounds true for anyone only using HPs mixing, mastering. So whats your take on this topic, open or closed ? and for that matter on, in or over ?( for me the only alternative is over) and now to the reason for this post. I have some very comfortable AKGs, so comfortable that I forget to take the off when fetching coffee, making it time to switch. What is your favorit HPs model and brand? Best Regards P-G
