[Elecraft] CM500 headset on K3S and KX3?

[Edward R Cole]

A couple years ago I bought the CM500 based on al the nice comments 
by others on this list.  They failed me terribly; set up howling like 
a banshee minute I put them on (over my hearing aids) and not even 
connected to the radio.  My hearing so poor that the amount of gain 
in my hearing aids fed back inside the acoustics of the 
ear-piece.  No amount of fiddling with the headset stopped the 
feedback, so went back to wearing my Sony MDR-V600 stereo headset 
(which work well with my hearing aids).  One if you bought the new 
CM500 from me for a nice discount, so I didn't loose out completely.

I got a lot of advice back then which did not help/fix the problem 
(not wearing the hearing aids and turning up radio volume was one).

In stead, I found a boom mic that attached to my Sony headset via an 
earth magnet "thingy" and that got FB audio reports.  The mic has a 
foam wind-blast reducer and selectable omni or cardiod pattern pick 
up.  Haven't really used the combo as I normally use my  Heil desk 
mic in the shack.  The boom mic was obtained for operating portable outdoors.
