Do i need XLR cable or simply unbalanced cable for the headphone

Do I need a XLR cable set up headphone?
What advantage will it contribute to the listening experiences.

Summary of article
Balanced cable designs, i.e.XLR solution is all about noise isolation especially long cable runs. It addresses noise transmission from mics or instruments that have to feed to the sound board some few hundred metres away from the stage during performance or in recording studios.

But headphone cables are less than 3 metres will see minimal noise. Hence you can get XLR mods when you have extra cash to burn.

Bonus material
This web has a silent CD/track used to test equipment for noise

This is one of the sure ways to check for noise in your DAC/AMP/Headphone setup!

Discussion

This thought came about when i was looking for a used T1 and saw one with XLR balanced setup going for S$750 which is really affordable compared to the stock 1/4" connector going around S$800.

The hesitation for me are
1. XLR outputs are rare in non high-end headphone amplifiers.
2. An adapter for XLR to 1/4" unbalanced is required to sample other normal amps
3. Amp costs.

Most headphones are sold with an unbalanced 1/4 jack like the photo below.

The stock Beyerdynamic T1 has an unbalanced 1/4" Neutrik connector.

An additional blue wire is un-used and is said to be able to convert the connector to XLR balanced 4 pin.

AMP costs
OPPO HA-1 Headphone Amplifier, DAC & Pre-Amplifier
USD $1199

MJOLNIR 2 TUBE OR SOLID STATE BALANCED HEADPHONE AMPLIFIER
USD $849

This is the Chinese Amplifier we have
RMB 520, about S$115 or USD $80 that drives the Beyerdynamic T1 really well which we are really happy

Its all about NOISE

Screen captures from videolink #2 below

Unbalanced: 1 metre cable. Nice clean sine wave

Unbalanced: 25 metre cable. Fuzzy (noise) sine wave. Cable acts like antenna, picking up noise.

Balanced: 25 metre cable. Clean sine wave. The signal amplitude has doubled as an added benefit.
