RE: Ear protection

[Matthew Black <Matthew.Black () csulb edu>]

I use the 3M E-A-R plugs at home and love them. Since my tragus doesn't fold over, I am unable to use traditional Apple 
earbuds or other things that just fall out of my ear. 3M E-A-R plugs are like memory foam and fit snugly, providing 
excellent noise reduction. I use ComplyFoam on in-ear headphones for the same reason, because those thin rubber ear bud 
covers are useless.

What are people using for ear protection for datacenters these days?  I'm
down to my last couple of corded 3M 1110:

These work reasonably well in practice, with a rated nominal noise
reduction rate of 29dB.  Some people find them uncomfortable, but they work
well for me.

There are other ear plugs with rated NRR of up to 32-33dB.  Anyone have any
opinions on what brands work well for them?
