AC454 Deluxe Stereo PNR Headset with PTT

After I got my PPL I used these as my headset. About 3 years old. Includes carry bag.

Ultimate performance, incredible voice clarity, higher noise attenuation and lighter weight.   Avcomm AC-454 Headset features great comfort and better performance, with many additional features built in. This headset has been designed with comfort as a priority and has a large foam pad across the top of the headband and ear seals that form a luxuriously snug fit around your ears. The AC-454 is fitted with the new enhanced noise-cancelling electret microphone for the clearest transmission. This microphone has been improved and comes with a special 'active filtering chip' which attenuates up to 75% of ambient noise and stops this aural noise from entering the headset. Also, the sound quality produced by Avcomm's new speaker technology within the ear cups has been improved by the addition of more powerful, ultra-light micro-simarium cobalt speakers. Complete with dual volume controls, mono / stereo switch and a built in PPT. The AC-454 has a fully adjustable headband and microphone boom.
