[K3] weird VOX experience with headset mic

[MontyS]

I just bought a Plantronics computer gaming headset, model 377, to use with my K3 after reading some of the posts about the Yamaha headset. (I had some bonus bucks to use at Best Buy.  They don't carry the Yamaha CM-500)  It works beautifully with one funny problem - if I try to use VOX, the radio goes into transmit mode even if I have the microphone muted.  I figure the receive audio must be inducing enough signal on the mic leads to trip the VOX.  No setting of ANTIVOX gets rid of this.  I have the audio from the K3 as low as possible.  Any experiences and suggestions welcome!

If I understand you correctly, I experienced a similar situation with a
very nice Razer gaming headset (for video games, etc).  It has great
over-the-ear cloth padded cups, an electret microphone element, and is
built very solidly.  In VOX mode on SSB it kept triggering into transmit
unless I turned the headphone volume way down.  As best I can tell, the
boom for the microphone is so solid that sound vibrations from the cup
are traveling down to the microphone element.  Thus far I haven't been
able to make it go away with ANTIVOX.  I have a half dozen other
headsets and none of them exhibit that problem, but none are built as
mechanically solid as that one either.

Sorry about the reply to a really old posting.  I had inadvertently
resorted some older emails by topic instead of date.

Try to fit a rubber or Neoprene sleeve/grommet between the mic boom and the
body of the ear shell.
