The Details:

Ultra-lite Neodymium speakers give you richer, smoother frequency response for both voice and music, while producing incredible efficiency that emphasizes higher frequencies. The powerful magnetic core and diaphragm were the perfect choice for high sensitivity and optimized response. Additionally, the speaker is a thin lightweight 4/10th's of an ounce, reducing headset weight for added comfort. Audio performance notches up even higher with the advanced speaker installation technique that reduces internal ear cup vibrations and increases noise attenuation.

An M65 microphone with ceramic hybrid active filtering chip amplifies desired voice signals while eliminating up to 75% of the background noise so that you can be heard more clearly in even the noisiest of environments like open cockpits. Additionally, the pre-amp circuit is immune to environmental changes, will not corrode, and has a much longer life than conventional PCB based products.

If you have ever had a yoke mounted push-to-talk fail, you will appreciate the convenience of AVCOMM's additional push-to-talk button built into the ear dome. This is a favorite feature for anyone who needs an extra push-to-talk to transmit easily and effortlessly without reaching for the controls.

Additional features in the AC454 PNR™ include convenient monaural to stereo settings for well balanced sound, volume controls on each side, durable copper wire with spiral shielding to eliminate RF interference and a polyurethane cover for added abrasion resistance and flexibility, gold plated mic and headphone plugs, high impact ABS ear cups, easy-to-adjust stainless steel headband with easy thumbnut adjustment, deluxe comfort head pad, acoustic foam ear seals, 100% cotton ear covers, an acoustic mic muff to protect against moisture and wind noise, plus a full five-year factory warranty.
