Thanks everyone for sharing your insight. Seems like I need to do lots of ear training and exercise using PA and hearing those compression/eq via HP.
I struggle a bit because my venue is school auditorium and things can get loud even when I’m on HP.
So far I’m using Audio Technica ATH M50. I tried Sony MDR 7506 it’s ok but not comfortable to hang around neck when not listening. On my next mix, I will try using a Shure SE215 IEM, with Decibel Defense earmuffs over it. I guess that will be a good insulation to hear clearly 🙂
