I'm looking to modify a set of hearing protectors that have an existing audio input (they're electronic), to include a microphone to be used with a radio for communications, However I can't seem to find a suitable connector that matches the overall budget I'm going for. Everything I've come up with is overkill for what I'm trying to do. (hirose connectors or legitimate military grade connectors which cost half what the headset does)
I need two conductors (mono) and some kind of locking mechanism, be it a threaded collar or etc, but it needs to be on the smaller side, something around the size of a 5.5x2.1mm DC jack or a 3.5mm audio jack.
It doesn't need to be explicitly for audio, any connector that fits the bill from another application will work just fine, I'm just not coming up with anything that is relatively inexpensive.
