First off, I hope this is mostly on topic.

I am in the process of modifying the design of a raspberry pi like device to fit it with a 5 pin xlr jack for connecting a stereo intercom headset. I know the pinouts of the two connectors are basically compatible, meaning I can connect headphone ground to headphone ground, right to right, etc.

I was wondering if the levels coming out of a consumer audio product using a TRRS jack would be at all compatible with a pro level headset or if I would have to use some sort of level shifter.

Edit: I have googled this, but all it comes up with is questions about connecting an ipod to a mixer via a 3.5mm to xlr converter. No info specifically about headsets.


  • Would love an answer for this! Am looking to connect a 4-pin headset in the same way, only in mono over both headphone channels. Pin out is easy for sure, just don't want to blow any preamps.

It will most probably work fine. The only difference would likely be the impedance, pro level equipment typically having higher impedance (200-600 Ω) than consumer products (< 100 Ω). All this means is that a consumer device may be easier to drive (higher volume in headphones) and that the microphone may put out a stronger signal. This all depends on the type of preamp/output amp in use, however. This article is an excellent source of information: http://www.soundonsound.com/sos/jan03/articles/impedanceworkshop.asp.

All in all, I would say: go ahead and try it!
