Does balanced adapters works?

I see this 3.5mm to XLR balanced : https://www.amazon.com/balanced-Female-Balanced-Hi-end-adapter/dp/B07C992Q1L, does it make a real balanced? How much improvement for balanced dac's like SMSL SU-8? I was wondering because I only see a balanced cable for EL-8 At an astonishing 310$ price: https://www.moon-audio.com/silver-dragon-cable-for-audeze-el-8-headphones-v3-by-moon-audio.html and i would to know how much do you suggest me a balanced adapter like that, or if it's better the Simpler 3.5mm. Thanks :)

This is different thing. Balanced connection to headphones is pretty new and isn't really standardised. Adapter from XLR-4 to 3.5mm TRRS jack linked in first post allow to connect balanced headphones with TRRS jack (4 pole balanced, don't confuse it with TRRS commonly used for headphones with microphone) to XLR-4 output in yours headphone amplifier.

I assume you are talking about front connector on an SMSL SH-8 (not 'U')? The balanced connectors on the back of SMSL SU-8 and SMSL SH-8 are for line level signals. They are not meant for driving headphones.
No, SU-8 dac, it have a balanced output for amplifiers i guess.. Oh, right, so i need balanced amplifier to benefit the overall balanced sound xD

In other words, if the cable on your Audeze EL-8 is already wired to a 3.5mm TRRS jack with the same pinout as the adaptor, then yes. It might work.

But if the cable has the much, much more common 3.5mm TRS jack in a single ended configuration, then no.

Yes, notice how the XLR connector on the adaptor has four pins (and has the wrong gender), while the connectors on the back of the DAC and amp only has three. They handle two completely different things (well... not completely, but you get the picture).

:D Then 100% or 50% useless?
Neither (or both!)

If you need to connect a balanced output to an unbalanced input or vice-versa, then an adaptor will do, so 100% successful. If you want to create a balanced output from an unbalanced output, or a balanced input from an unbalanced input, then you need either a transformer or an active stage, so an adapter will be 0% successful.
It depends what you want to do.

Considering that balanced headphone driving is a total and utter con trick on the untechnical, as it has zero technical merit, I really wouldn't bother either way.

For the reasons why balanced headphone driving is a con, just think about why is would be a benefit. Then think about how much crosstalk is actually introduced by the common ground impedance, and think about how much crosstalk is actually mechanical, going across the headband.

But yes, moot point. A single ended output with the same power capabilities will do the same trick.
Considering that pretty much all headphone outputs are capable of causing hearing damage with any sensible headphone, I just don't get this obsession with more output.

Do you even have a headphone that terminates in 3.5mm TRRS with R+, R-, L+ and L-? (Not the commonly found R, L, Ground and Mic present in phone earphones.)

New into these things but.. Looks like no! So i guess even balanced adaptors aren't supported in this cable, right?

Correct. It only has two sinal wires + Ground. But like sergeaukland says, dont worry about it. Get an amp with single ended output and be happy :)
Yeah I buy D50 and Jds Atom days ago, still waiting, i'm upset.. Actually i ordered El8 closed on amazon days ago, they send me the Sine X.x Now i have money For El8, i hope to have it soon, no money for send all the return of amazon lol So, no El8 closed but I have: Mdr-Z7, Audeze Sine and Audeze Mobius with Pha-3 Amp :) I'll try to enjoy all these kids and learn from them ahah One day i could pass to full balanced if it's worth it in terms of separation of channels, soundstage, power etc..
