Rip-G
"Rip" was already taken
This is the first time I hear about closed cans but it's well known that singers tend sing too high if mix in the cans is too loud. Also if you make their own voice lower in the mix they will try to compensate and scream louder. The opposite is also true - if they are very loud in the mix their singing will be softer.
You can try recording without cans - with your monitors blazing, just cut out stuff without voice later on. Works for rock and metal.
