Looking for a K3 OEM mic with the 8 pin connector for the front mic connection. MH2 handheld is the OEM mic. I'm using Yamaha CM500 headset, and have it working on my KX3 very well. Also have it working on the K3 Rear mic port but doesn't work on the front mic port through a 8-pin to 3.5 adapter I bought. The adaptor 'SHOULD' work well. Anyway, would like to try an OEM if anyone has one and would loan it to me for a couple days.
