Custom Headset Adapter

[ShowMeCablesDrew]

I am going from 5pin din to TRRS.. (please see attached photos) This is for a motorcycle headset.

tip - left audio
ring 1 (closest to tip) - right audio
ring 2 - mic
shield - ground


Tip------------------------5
Ring1----------------------4
Ring2----------------------1
Sleeve---------------------2

With the two grounds (pins 2 & 3) tied together. This is the best method I can think to do this. I asked a few of my colleagues and one of them expressed some concern that tieing the mic in and audio out ground could cause quite a bit of feedback. Some equipment will work fine like this, but other equipment will not function properly.

I was wondering if anyone has ever tried anything like this, or can offer any insight as to whether this will work or not.

Thanks!
