That is correct but the spacing of the rings can be different than the stereo plus. Did it come with TRS connectors? I would use that type and you still just connect tip and sleeve
Thanks for the quick help. Actually, the connectors I bought are mono (TS) (Rean NYS226BG) because many of the after market balanced cables sold for newer Hifiman cans (3.5mm) use mono 3.5mm connectors. Based on your reply, when using mono 3.5mm connectors for these cans, the tips are L+/R+ and the sleeves are L-/R- based on your post. Looks simple enough, thanks for your help!

You may well be all right, and yes the tips are left and right plus, sleeves are left and right minus.

Both stock cables for PFE 232 were dead a year back and my favorite IEM was catching dust. Last week I used connectors from Stock cable and made my own custom one.
Now rocking with 232 again, with sliver only cables it more balanced now.

I'm planning on making a female 4-pin XLR to banana plugs for a Hifiman Susvara. Are Mogami W2893 wires ok for that application? I don't want a speaker amp destroying anything.

How do you gonna split it?
You need something like this:

or this https://www.redco.com/Mogami-W3106.html

"I don't want a speaker amp destroying anything"
what do you mean?

- you have to check with voltmeter any continuity leakage between all of the connectors.
- you can test on 100% Left side setting, if only the left side function (no leakage or problem to Righ)
*then do the same for the Right side:

I made a lots of mistakes past days with the soldering and connectors

I'm probably gonna have them in Paracord and then braid them. Should the Mogami W2893 wires still be ok? I've used those before so I'm more comfortable using those.

>what do you mean?

I fried an audio component from a speaker amp before so I'm being cautious just in case.

I have made a few custom cables before though just wanted to know if I'd have to get different cables if I were to hook it up to a speaker amp.

You said 4pin xlr (balanced)
now you say - speaker amp ...

26 AWG
Served Shield Approx. 73/0.12A
Electrostatic Noise
50mV Max.
Electromagnetic Noise 0.15mV Max.
Microphonics at 50K / Load 30m V Max.
Voltage Breakdown Must withstand at DC 500V/15sec.
Insulation Resistance 100000 M / × m Min. at DC 125V, 20°C

from this site: https://daleproaudio.com/products/m...or-balanced-audio-cable-black-200-meter-spool

If you gonna use it not with headphones amp then I don't know how much it qualified for it!
I think that it will function fine without any problems but still not quality enough for speaker cable .

My electrical knowledge is very low!

FIXED IT SEE EDIT***
When making a dac to amp interconnect from TRRS to L+R 3 pin XLR I ran into a ground issue. The TRRS DAC side of the cable doesnt have anything to connect to the XLR ground pin.
The issue is the dac and source on the TRRS side use switching power supplies (ungrounded 2 pole power plugs and one grounded but plugging it in doesn’t resolve the noise) and the amp/xlr side uses grounded 2 pole. As long as I use battery power on the dac/source side of things I’m okay, but god forbid i plug in the dac or source or anything else on this side of the chain to a charger. Noise City -from the switching power supply i assume.
I have tested using a temporary dedicated ground setup I made and connecting anything on the dac side of the chain directly to the outlet ground fixes the noise, but I don’t currently have a dedicated grounding setup to always do this.
So I’m just wondering what I can do for a permanent solution. I’m looking to see what y’all suggest. Did I just make a dumb mistake building the cable or maybe there’s another/better solution I’m overlooking. Thanks.

***EDIT: Found a solution for the Dac I’m using. (LH GOV2+ or any geekout dac with balanced output)AD907898-2864-4076-8C8A-D02D252718C1.jpeg

I'м planning to make a cable for my HE6 headphones. But while looking for suitable 6.3mm and 3.5mm plugs, I saw that they were mostly made of gold-plated brass, and it's electrical conductivity is many times lower than that of copper or silver. Logically, whenever is quality of copper or even silver cable is high, the sound quality of the whole cable will be exact as the quality of the weakest link of the chain - the brass plug's electrical conductivity / purity. Does anyone know is there any gold or silver plated copper plug in the market?

Not sure if copper based but these are about as good as you can get and they stock a whole range of any connector you want in all prices, good luck
Thank you for an advice. Just checked the specifications, and even these are expensive connectors, there is no pure copper, as : Main conductor: for Furutech: Nonmagnetic Rhodium-plated α (Alpha)Phosphor bronze conductor; for Eidolic - copper alloy (I’m reckoning that would be brass then?) plug chassis, layer of rhodium.
So for above mentioned alloys we have (if electrical conductivity of Copper is 100%): 11% for Phospor Bronze, 28% for typical brass, 38,40% for Rhodium. Unfortunately, even the Aluminium has 61% of Copper's conductivity.

You also don’t encounter pure silver solder. Like solder, a connector has physical requirements that one can’t meet using pure copper or silver. You need rigidity/durability that can only be achieved by alloying.
