Ear protection

I use these normally. http://www.howardleight.com/earplugs/laser-lite

I am surprised some datacenters don't have a requirement for ear protection when entering their facilitiy. Most large construction sites I have been to required me to have ear plugs at least in a pocket and I have been to a few factories that required them on at all times. Many times these sites are quieter than the usual DC.

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?
