Drew, et al
The HGU-68/P is my choice of helmet also. Work great for us over 6' tall as the one-hand-operation knob is left of center and saves almost 2" of canopy clearance vs. the HGU 33.
The hearing device you mentioned is the C.E.P (Communication Ear Protection). This device is common with Helicopter pilots and as far as I am concerned is superior to the ANR. The ANR "cancels" the low frequency range but all the noise still hits the ear drum. The ANR does not provide any enhance passive noise reduction over the helmet's existing insulation.
The CEP is a neat and simple solution that works so well in my CJ. A simple pig tail wire is attached to one of the helmet earphone (in parallel) and than splits to a "Y" that have a transducer embedded in an ear plug that is made of the same material as standard foam earplugs that you roll between your fingers and place in the ear opening. This foam provides a very efficient Passive Noise Reduction while the audio is ported right into your ear canal (the foam earplug is hollow in the center to allow the audio to go directly to your ear drum). Works amazingly well and provides better noise protection (30db). Also, I don't need to set the radio or intercom volume to max and I do not need another power plug (as with the ANR) and you can fly in any aircraft again, without needing a power socket or drag your battery pack...
You can log on to the manufacturer's web site to get the details and to order one, if you wish. Cost is around $120.

After checking out the HGU/68P helmet, I'm getting one and paying for it through the savings made by using autogas in the 285...
Thanks Craig and Brian,
PS: Sam Sax has a new device for the hearing impaired; the ear plugs have the micro-speakers factory imbedded, so its seperate from the helmet! Your helmet can be passive noise canceling, and you further have standard ear plugs. Would seem this would cut down the most noise for those already on the road to becoming deaf...it looked pretty slick, I don't know the manufacturer?
