Hi Phil,

I can't speak to the quality of the mic on those earbuds, but there are
a number of splitter cables out there that will split the mic and
speaker signals form the TRRS jack on you earbud cable to the mic and
speaker connections on your KX3.

I use one I ordered from Amazon to do just that when using my ASUS
T100TA tablet for digital modes with my KX3. Sorry I don't currently
have a link, but there are a number of them out there with various
prices and quality.

When I operate portable with my KX3 I am often favoring my Apple iPhone
earbuds over other headsets. I have no measure of whether these are
better or worse then others (I also own CM500 but it is big and bulky)
-- but they work fine for me so far. And, in portable ops, I have been
100 percent CW so voice quality has not been an issue.
But...
If I wanted to switch to SSB for some reason I am thinking: "Is there a
way to use the mic that is integrated with these iPhone earbuds?".
In a perfect world where there is no resistance nor taxes, this would
work without any special plugs or jacks just like it works on my iPhone
but I don't expect that. Has anyone done this? Has anyone adapted this
mic for use on the KX3? I don't even know the mic technology (electret,
dynamic, etc.).

Dave,

Thanks. Just when your message popped in I was actually looking for splitters. Found a Griffin MicConnect interface but that is not what I want. From what I have learned so far, the mic technology assumed by the iPhone is passive Dynamic mic. No Bias is supplied by the iPhone (probably would have been my guess anyway).

I would think you are right also.

I apologize for the lack of correct terminology. I was in the middle of
my first cup of coffee ;-)

I meant the "plug" on your earbuds - not jack. I have the version that
splits the jack signals on my tablet. You would need the opposite
version I use. I bought a couple for spares - they were only a few bucks
if I remember correctly. I'm sure it will work fine and sounds like a
nice compact setup.

Take care & 73,

The only kinds of splitters I have found are actually combiners: separate mic and headphones connections to plug into an iPhone.

A few people say that 1.5-2.5V is provided for the microphone. This makes since, because they need to sense the button presses, too.

Most people are trying to put other headsets on iPhones or Macs, but the info may be useful.

Thank you. I wonder how I messed up when I searched on Stack Exchange. Did a lot of searching this morning so probably likely to miss a lot of stuff.
