For years we have used the Peltor/3M Bluetooth headsets in the datacenter. Proper hearing protection and noise cancelling mic, with the added bonus of protecting my head a bit when I am up on the ladder in the DC and can easily bang into potentially sharp things. http://goo.gl/ShTCEF
They are about $375-$450ish retail, we picked some up on ebay in around $200 brand new. We have about 6 pairs that so far have lasted 8-9+ years with no problems. The only major suggestion if you are going to use them on a regular basis is to get the gel earcup replacements. These seem to be about $60ish.

I'm down to my last couple of corded 3M 1110: http://www.shop3m.com/3m-corded-earplugs-hearing-conservation-1110.html 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? Nick
