Hey, Got a question about 2-Pin to 4,4 mm Pentaconn IEM cables. Recently I got a new one and of course I checked it with a DMM.
There R- of 2-Pin IEM connector is not only connected to R-, but also connected to Pentaconn ground. That isn't done right. However I heard the ground doesn't matter anyway when using Pentaconn balanced, does it? So is it safe to use my IEM with this new cable or should I resolder? Using portable amps like iBasso DC-Elite and Xduoo XD05Pro.

I can’t really answer your question. But, yes stuff like Sony DAPs don’t use the TRRRS ground with 4.4mm plugs. I have gotten a miss wired cable which even changing the 2 pin polarity didn’t fix the issue, it sounded like the music was farther away and under water almost. Yet the miss wiring didn’t hurt my 1Z or 1A, and I was mailed a replacement cable. Hope this helps.

While the ground isn’t used in headphone cable application, only interconnects, the problem you encountered will connect the R - to the ground of the amplifier as well as the IEM which cannot be a good thing.
I would certainly correct that.
It is possibly as simple as a little dag of solder touching the R - and the body of the 4.4mm plug effectively grounding it given that the R - and the body of the plug are beside each other and close. Likely a simple fix if you can get the plug open without damage.
