Classic Redefined

15 Years of Lune

Lune has been a Null Audio best-seller for 15 consecutive years. MKIX uses Null Audio’s proprietary silver/copper fusion alloy in UPOCC cast with thick silver plating.

Construction

Custom Litz Geometry

53 thick strands per wire, 212 strands per cable, in a custom Litz configuration. Super low impedance reduces transmission phase shift and distortion for precise imaging, rich mids and textured bass.

Oxidation Prevention

Clear for Longer

Internal braids are individually insulated with a PVD-deposited clear coating, and the ultra-clear, soft outer sleeve resists yellowing. Together they protect against oxidation and colour change.

Care

Caring for Your Cable

Coil it loosely in large loops and keep it in the included leather pouch when you’re on the move.

Unplug by holding the connector, not the cable, and avoid sharp bends right at the plugs.

Wipe it with a soft, dry cloth, and keep it away from solvents and alcohol-based cleaners.

Every cable has a 1-year warranty. If anything goes wrong, contact us and we’ll take care of it.

Questions

Good to know

How long until it ships?

Every Lune Series MKIX is built to order by hand in Singapore. Lead time is around 1 week.

What if it doesn’t fit my headphones?

The plug is matched to the headphones listed on this page. If the cable doesn’t fit the headphones you chose, tell us within 30 days of delivery and we’ll make a new one free, shipping included.

Check your headphone’s plug

Can I get a different length?

Yes. Choose Cable length in the configurator above: set any length from 50 cm to 3 m in 2 cm steps. Up to the standard 1.5 m costs nothing extra; longer cables cost more, and the price is shown before you add to cart.

For a length over 3 m, contact us or WhatsApp +65-8731-5476.

Will the cable turn green or yellow over time?

It’s built not to. Lune’s internal braids are individually insulated with a PVD-deposited clear coating for an extra layer of protection from oxidation, and the ultra-clear, soft sleeve is yellowing-resistant.

What is the return policy?

Standard builds can be returned within 14 days of confirmed delivery if unused and in their original packaging. Change-of-mind returns carry a 30% restocking fee, and shipping is not refunded.

Custom spec, length or connector builds cannot be returned for a change of mind once production starts. Faults are a different matter: every cable has a 1-year warranty, so contact support@null-audio.com and we will assess it.
