[Elecraft] Headset/Mic Question

[William Wallace]

Hello all,

New to this reflector.  Waiting for my K3/100 & P3 kits to arrive.
I want to use a Yamaha CM-500 boom set with my K3 but think
I should ask if anyone else has experience using this combination.
There must be a connection adapter used between the boom set
and the K3 mic connector, correct?  Any recommendations and/or 
comments welcomed.  I know W2ENY
http://members.bellatlantic.net/~vze3rys4/adapter/ 
makes/sells an adapter, anyone using one of these?
