Doc,
Would extended length of the nasopharynx have an effect?

Brian,
The Communications & Ear Protection system is what I had before the Westone system. Did not like it very much. Still had difficulty hearing the radio. It was touted as having superior noise reduction, but I found it lacking in many ways at the noise levels we experience in the CJ. My Lightseed noise reduction headset did a much better job, but would not allow me to wear a helmet.
Ear hair? You know, as we get older that damed ear hair gets tougher and can keep the expanding foam earpiece from sealing in the ear canal. I am guessing that it may be different for different people.
One way to find out is if silicone foam earplugs work. If they do, then the CEP earphones should work too.

Nels,
Yes you can modify it relatively easy.
I purchased a civilian mike & earphones form Gibson/Barnes, then a
converter that plugged into the single plug to two plugs.
Works great.

I have that adapter also to use with my current helmet. It is a bit weighty and unruly under G.

Gibson-Barnes also has an adapter cable. Assuming you have the standard U-174 connector on the end of your military helmet, you can take out any pre-amp module that might have been in the O2 mask, and using the stock mike and earpieces, the adapter cable will match the impedances and you can use it with the original earpieces and microphone element. It converts the U-174 connector to what is usually used in general aviation, which is the mono headphone male connector, and the standard mike plug.. the nomenclature of which I forget! Sorry.
Anyway, I've tried it, it works.... but I'd recommend doing what the folks below are talking about versus this. Just letting you know it's there.

There is a long and a short version. Secure it to the airframe. The
female plugs are held in place with Adel clamps, so ......
Yes, it you leave it just hanging, it is a mess.

As an Aerial Gunner on USAF Combat Search and Rescue helicopters, we use CEP's with our 56/P helmets. In our VERY noisey environment, they come in handy but with some limitations. If they are not placed perfectly in your ear, they can start to hurt. The small wire will push against your ear and after a short time, start to cause a "hot spot". Also, the wire has to be managed and is not very stout. The ear cushion has to be replaced every 20 uses or so. They compliment the comm's and can be helpful. Sometimes, I just pull them out and put in ear plugs and crank the volume.

Using ear plugs and then cranking up the volume is what the motorcyclists typically do. It gets really noisy inside a motocycle helmet in an 80mph (or faster) breeze.
But I like the idea of CEP or something like it (in the ear canal) because active noise reduction does such a poor job attenuating upper midrange and high frequencies. Between shooting and flying (even though I always wear hearing protection) I now have tinnitus. Anything that reduces noise and makes the comm frequencies clearer helps a lot.

That's exactly what makes ACCES from Westone great. They are formed from your own ear and can only fit in one way. Once installed correctly, they're no problem.
