Custom Plugs
 

My favourite setup is to use custom ear plugs under my ANR headset. Etymotic Research, Inc. - Musicians Earplugs High-Fidelity Hearing Protection I've tried CEP's under a David Clark passive headset (with foam tips) and found I got ear pain after 6 hours of flying a day. I'd like to try CEP's with custom molded tips, it might be an improvement but I still feel they will stick out too far into the headset cup and cause pressure issues.
The custom plugs work well for me as I can wear them all day (8 hours +) with no discomfort at all and the musician filters preserve the frequencies while lowering the decibel level (no muffled sound like normal foam ear plugs).

That being said I'm still on a quest for the perfect noise reduction (still suffer from ANR induced wind noise issues with my Lightspeed Zulu) but my comfort issues are all gone.

I've used CEP for around 5 yrs. now, with foam tips. Comfort is an issue after 4 hrs. or so, but bearable. My biggest issue is the wire breaking by the earpiece.

I try to be gentle when using, never pulling directly on the wires but no love they break every couple of yrs. requiring replacement, on my 3rd. pair now.

Even with the wear issues I find their effectiveness more than justifies the cost.

I have been using CEP's with my David Clark ANR headset now since 2007. Flying between 60-120 hrs a month. I had an issue for a while with them applying too much pressure on my ear cannel (DC headset applying pressure), but I bought Oregon Aero ear muffs and have not had an issue since. My CEP lasted me until last week when one of the transducers pulled out of the housing. I got in touch with CEP-USA and they very happily sent me a replacement.

I can tell you that for me they are superb, great audio clarity and noise protection.

CEP in ANR headset
 

Hi,

I would like to install CEP in my Bose A20.
Has anyone tried CEP in a ANR headset?
And has anyone installed it in a Bose A20, and how did you do it??

Thanks :)

It's been done, one of the guys at my last base put a cep system into his first generation ANR Bose, and he was quite impressed with the results, but I cannot offer any guidance on the "how to".

If you contact CEP Direct in the U.S they will fit it for you at a cost.

I have been using them for a long time about 8-9 years. I get tested every year for hearing loss by my company. I have had little to none as far as loss. I use a company that makes the mold of your ear. precision labs Products they make them for all kinds of applications ipods, tactical, shooting. I have a few sets just in case one is broken. I just send one back and ready to go with the other. I dont fly without them. I use to fly with the volume all the way up and now its just cracked open. not cheap but good quality.
