Clay,

On your K3S, did you try plugging into the rear phones jack? You can do that without any 1/8 inch to 1/4 inch adapter.

The resistance of each earpiece should be easy to check with your ohmmeter and be revealing if there is a cord problem. The left channel (tip) should compare with the right (ring) unless something is open or shorted.

Anyone ever had a ProSet two fail to deliver two channel output when everything is set up correctly (aka bad cable or failed R channel solder joint at one end or the other)?

My Elmer has a set bought in April of this year and has never been able to get right channel.  I took it today to try on my K3s with known good setup for 2-channel into phones (Sennheiser HD598SE).

Same problem on my radio...  no right channel.  Almost HAS to be 1) solder joint failure on one of the wires to the driver, 2) a right channel (+) solder failure at the 1/8" TRS, 2) failed right driver. It's a non-coiled three cable-bonded cord...  so I am assuming 3 conductors with shields for ground.
