Well, I do not have first hand experience, so I had to rely on search. And this is what I've found:

Thanks so much for posting this! I have been looking for that stupid Kobicon wiring diagram for a month and couldn't find it! Now I can make my ridiculous adapter for an amp that uses this connector.

It's a typo and good thing you asked about it to clarify it HifiMan, Oppo (PM3 headphones), Plenue S (the only Plenue module, because Plenue 2 and Plenue R use 2.5mm balanced), and GeekOut USB DACs use 3.5mm TRRS balanced. I have all of it, except PS. I'm not aware of any other DAPs with 2.5mm TRRS jack wired other than A&K standard.

Thank you very much for clarification Especially that I happen to have Geek Out V2+, so I am really interested in balanced 3.5 mm TRRS too. Which kind of pin-out does it have?

Thanks again!

Though off-topic for M3s discussion, HifiMAN 3.5mm TRRS balanced wiring (LH labs too):

Thanks again and apologies for off-topic. But great to know that with M3S I can use any 2.5 mm balanced cable, which I'll need quite a few

The Fiio X7II uses 2.5mm TRRS balanced as well.

Yes, but just to clarify before we get too much off topic , the original question was about 2.5mm BAL pinout of Shanling M3s since one of the websites (diyaudio...) mentioned incorrectly about 2 different pinouts of 2.5mm TRRS termination. They had a typo for devices that support HifiMAN 3.5mm TRRS balanced pinout, saying it was 2.5mm TRRS balanced instead of 3.5mm. That's how the whole discussion started

But indeed, Shanling, just like many others (FiiO, Cayin, theBit, Cowon, iBasso, Aune, L&P, Lotoo, Hiby, Questyle, etc), support A&K 2.5mm TRRS balanced pinout.

Could someone please explain the Auto Standby function for me?

What happens if we used a different 2.5mm TRS cable ?

You short the -L and -R lines together and fry your amp circuitry.

oh what... i better becareful choosing a balanced cable.

I don't think anybody intentionally makes 2.5mm balanced cables that wouldn't work with the M3s.

 

[PinkyPowers]

Nope. Any 2.5mm balanced cable will work. But you said 2.5mm TRS, which is single-ended (AKA NOT-balanced). TRRS is balanced.

 

[liquidrats]

Oopss sorry my mistake

 

[Dobrescu George]

Since we're in a bit of a OT anyways, @twister6 @PinkyPowers you guys seem to know this - there are cable producers, like MEE who are making a cable with many adapters, even having something that turns 2.5 TRRS to 2.5 TRS , that is safe, no?
