I normally use 3.5mm - rca connect to my nw-zx300 so will it make differences if i move to the balanced output using the adaptor?

I gather that the NW-ZX300 also has a 4,4mm balanced output. This Gerika adapter however has a serious fault: three poles are electrically shorted so it can only function as an unbalanced adapter (unless Gerika have fixed the problem). This can easily be verified with any multimeter. Obviously the balanced output requires four separate electrical connections to your headphone: two cables to each "ear". To enjoy the balanced output you obviously need headphones with a balanced cable (4 poles/wires). Do not connect unbalanced headphones to a balanced output. If you fulfil those requirements, you also need a true balanced 4.4mm to 3.5mm adapter such as the "Meijunter 4.4mm (Male) to 3.5mm (Female) Balanced Cable Plug Adapter for Sony PHA-2A/iBasso/Fiio/HiFiman Headphones, Replacement Metal Cord Plug Line Jack Connector" in amazon.com. This correctly passes 4 poles from the male plug to the female socket.

Would this work to get 2.5mm balanced output from my es100 dac, for HiFiman Sundara w/ 3.5mm jack?

I believe the balanced outputs (on the DAC) are either 2.5mm or 4.4mm. Most ALSO have a 3.5mm jack. This adapter allows for use of standard 3.5mm headphones/ earbuds on 2.5mm outputs Adapters are available in most configurations. I would get an adapter for 4.4mm or 2.5mm ONLY. This particular adapter fits a 2.5mm output for 3.5mm audio connections. They won't make your 3.5mm output balanced.

Is the cable 2.5 balanced male to 3.5 balanced female or 3.5 unbalanced female?

This Geekria adapter is 2.5mm balanced male to 3.5mm balanced female.

Does this convert the output to balanced audio? Or just allow one to use balanced cables in a 3.5mm port? Is there a balanced audio benefit?

It only adapts. There is no balanced 3.5mm advantage.

Know that it's only an adapter, not a converter

It's important to understand this adapter simply allows you to connect a 3.5mm plug into a 4.4mm balanced socket, it doesn't convert any signals. I used this to connect headphones with a 3.5mm plug into a dongle with a 4.4mm balanced socket. All it does in this case is draw a little more power, because it makes the sound louder. There's no change to the sound quality. In order to receive a balanced signal from a socket, the headphones and cable itself have to be wired in a balanced configuration, otherwise the signal stays the same (unbalanced). Keep this stuff in mind to determine if you only need an adapter or you need to change the entire cable.

More power to headphones.

Allowed me to plug into my AMP and get more power to my IEMs, making them sound that much better.

better

i found that the 3.5 of an apple cord works better with this attachment if you have 4.4mm male option in your device

The audio quality is outstanding

I cannot praise the Geekria 4.4mm Balanced Male to 3.5mm (1/8'') Balanced Female Headphones Plug Adapter enough for its exceptional quality and customer service. Initially, I encountered a minor connection issue with the first adapter I received. Since receiving the replacement, I've experienced no issues whatsoever. The audio quality is outstanding, and the adapter seamlessly converts my 4.4mm balanced male connector to a 3.5mm balanced female connector, allowing me to enjoy my favorite music without any disruptions. The build quality of the adapter is impressive, crafted from durable aluminum alloy and featuring gold-plated connectors that ensure optimal audio transmission. The design is sleek and compact, making it convenient to carry around without compromising on its robustness.
