The MicMuff® Microphone Cover lets a noise-canceling microphone do its job above 97dB. Eliminates ambient cockpit noise and noise from radios and intercom. The noisier the cockpit (warbirds, open cockpit, large engine aircraft), the more dramatic the improvement in noise reduction and clarity. The MicMuff® Microphone Cover must be used on all headsets installed in the communications system. Soft, washable leatherette cover over foam sleeve creates chamber around microphone. Cockpit noise has limited access to microphone cartridges, but voice enters easily through holes in a leatherette cover. Elasticized tie ensures it won’t blow away.
Note: Every headset microphone used in an intercom system must have the micmuff installed in order for the micmuff to be effective! The only exception is the push-to-talk intercom system.
Helps with background noise in very noisy homebuilt airplane cockpit.
OREGON AERO ELECTRET MICMUFF +
I have used these products in the past and the fact that I am ordering some more speaks for itself. I also had the usual prompt service from Aircraft Spruce.
I have been using Oregon Aeros Mic Muff for a couple decades. Nothing else works in warbirds, open-cockpit aircraft, and other high-noise aircraft. New headsets always mean new orders for Mic Muffs.
Work as advertised on my Zulu 3
Big improvement on the Bose a 20 flying open cockpit it’s probably as good as it’s going to get
