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!
