Re: "Is there such a thing as a noise cancelling black box you can plug in aheadset such as the CM-500 and get good noise canceling? No knobs. Just anON-OFF switch like the headsets have."
Well, sort of, Tony. In the aviation world, conversions kits have been marketed for popular (in aviation circles) headsets to convert them to noise canceling. They weren't "black box" plug-in devices, but rather a kit of microphones and electronics mounted in each earpiece and required some disassembly of the existing earpieces. I believe they were made for David Clark and Flightcom headsets, and maybe a few others. The result was a significant improvement over the original passive headsets, but not as good as a good pair of noise canceling headsets. I don't know if they are still available. I suspect the low end of the noise canceling headset market has displaced them.

I would think they would be more comfortable than theplastic against your head. And they would look better than the pieces ofpaper towels I presently use when wearing the headphones for extendedperiods. :-)73,N2TK, Tony-----Original Message-----From: elecraft-boun...@mailman.qth.net[mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Gary SmithSent: Thursday, December 26, 2013 2:58 AMTo: elecr...@mailman.qth.netSubject: Re: [Elecraft] Noise Cancelling HeadphonesI use the Bose QC-15 as about all I do is CW and the audio on these iswonderful. The noise cancelling though is almost 100% perfect; my old Alphawith its blower is 18" from my head and with the QC-15 on I can't but just barely tell the amp is on or off. I was thinking about getting a headset with a mic & though Bose does makethe A20 for pilots, at $1100 for what is essentially the QC-15 with a boommic, I'll pass. They do make a A100T snap on mic for theQC15 but they are $250 for just the mic. I was referred by quite a fewpeople here to check out the Yamaha CM500 for a fine mic, quick match to theK3 and comfortable headsets & at $59. I'm so happy with the Bose QC15 that I'm going to keep using these and amgoing to need to figure out another way to get a mic into theK3 in a way that will be convenient for contesting should I ever decide todo a phone contest. I have an Electrovoice RE-10 which would probably benice & needs no power & maybe I can make a clamp-on boom that I can remove from the desk once the contest is over. I also have several condenser mics but they are for recording and would be excessand just problematic for ham use.Anyone have any suggestion of a removable boom mic other than the A100T thatwill attach to the QC-15 and make it simple to use and then remove when thecontest is over? I don't want to use velcro.Thanks & 73,GaryKA1J---This email is free from viruses and malware because avast!
