[Elecraft] Yamaha CM500 Headset

[Jaime P.Ullivarri]

Yes I see, the advert is wrong but I think the Koss is also electret, just a 
few days to know.
I don't plug my CM500 directly to the K3, it is connected with its battery 
to a NCS Multi=Switcher, I use it with other rigs also, so I have the K3 
bias OFF.
I will try the Koss directly to the K3 with bias ON.

My Yamaha CM500 does not have a dynamic mike, rather an electret.
