I recommend 385

I am very happy with this purchase. I do not put 5 stars because I do not feel the side "progressive". I tried all positions and latténuation does not change.
I am a drummer and that's three times I use it twice and repeats once in concert last night and once the caps removed, no fatigue. So far I used concert caps but the sound was so deaf after rehearsals and my ears were a little tired. There I really feel anything.
