Excerpt: The Yamaha CM500 headset is ideal to use with the Elecraft K3. It is plug-n-play, and the audio quality on both transmit and receive is excellent. And you can't beat the price, especially when compared with the Heil headsets.
Excerpt: I purchased these items because they were recommended to me by the sales person. a great deal of echo, very cumbersome and for the money not even close to doing the job....not even satisfied if they were half the price.
Excerpt: I bought the headset for my Icom 7400 radio. Works great. Excelent speakers and a very good mic. I think they are better than the heilsound and much cheaper. The quality is not good but still a great headset for the price.
Excerpt: The headset has replaced my high dollar Heil headset. Both headsets work fine although, the Heil weighs a ton and gets hard to wear after a little time. The Yamaha headset is light weight and has great audio both receive and transmit. regards, Rick
Summary: On my 4th pair of CM-500's since 2011, use them off and on with the Yaesu FTDX-5000, FT1000D and FT-1000MK5..the microphone went bad on 3 sets...seems the pivot point is where they might break down...tricky to fix, so I didn't mess with it...I use W2ENY adapter , works great..
Summary: I needed a mic-headset combination for portable use and field day. I use it with my K3 and TS480 and get great reports. I bought the W2ENY adapter for the 8 pin connection to the K3 and one for the TS480. Headset is very comfortable over long periods (think field day) and easy to carry in the RV.
Excerpt: Receive audio is good for voice work and is in stereo so you have dual receive options there. I found the mic fairly easy to use and position, but...I got maybe 3 years use out of mine before it started to break in various ways. That's light duty, a few contests a year and field day.
Summary: What can I say, it is a condenser microphone and a comfy set of headphones that go completely around your ears. I use the same audio levels on my radio as I do with the Icom microphone, didn't have to change a thing.
Excellent Audio, High Output Electret, Extremely Comfortable

Summary: I own and use an FT-1000MP. Although the MP does not have an equalizer, the 1000MP does, with EDSP, have five different transmit "EDSP" microphone settings. These settings are: OFF, 1, 2, 3, 4. OFF is pass through of the audio from the microphone, same as EDSP off.
