Very Nooby Queston about Jacks

I'm plugging a 3.5mm Heaphone Mic into a 1/4 Stereo Jack converter that's going into my Roland DJ-202 Mixing Console
The signal in my heaphones is scratchy and unclear.
It's only when I pull the 3.5mm jack out a little from the converter does it begin to sound okay.
At first \I thought it was the 1/4 Jack converter that was the issue but now i'm thinking it's because i'm plugging a Headphone MIC into it instead of Standard Headphones
Can someone knock it (me) on the head for me please before I go spend money on new heaphones. Which I think is a foregone conclusion anyway
thank you
