I have a home studio, for now I'm just doing my own stuff. I am new to recording and have a question on Headphones. I need to buy two headphones, one for me to do the mixing and the other for musicians playing, guitar, bass etc.. What is the difference between closed headphones, open headphones, and Hi FI Pro Stereo headphones. Also, can anyone suggest good but affordable headphones. I would like to stay under $150.00. Thanks!
