Hi
@Mhog55,
You almost got it...
Balanced cables generally have
3 poles, not 4 poles.
In other words, make sure the actual plug has only
3 rings.
The 4th pole is usually for the microphone signal &/or extra power from the amp circuit.
The only difference to this is some dual plugs will have only 2 poles for Stereo on each side & not Mono.
Generally, it also depends how a cable & plug is wired together internally, I have seen Stereo & Mono plugs become vice versa due to, let's just say,
interesting wiring techniques though if done correctly & depending on the plug, a Stereo Plug, like 3.5 mm can be Balanced if there is enough space for an extra ground...
Most if not all TRRS 6.3 are generally Stereo with 2 pole though they all it balanced.
Standard TRS is just Mono so all the terminations can be confusing at times.
The last thing is as long as there is no microphone built in & you can hear sound from both left & right, then yes, it should work fine.
Hope you have a great day !
