Currently supporting 2PIN, IE300, A2DC, IPX, Pentaconn Ears and QDC 2PIN.
Designed, handcrafted and shipped from Singapore.
Built-to-order. Lead time around 1 week.
Ear guide (~10cm) is installed by default for commonly used IEM connectors (e.g. 2PIN, MMCX, IPX). Let us know if your IEM/headphone is modified or needs extra customization.
Anti-Yellowing
Epsilon’s black insulating sleeve is made for prolonged durability and resists yellowing, so the cable keeps its look on stage and in daily use.
Care
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.

Good Upgrade Cable for IE600
I purchased this cable to replace stock IE600 cable. It is a cable with better built quality compared to the stock one. Sound clarity improve by a bit.
Quality Cable
Love the weight and thickness of the cable. Improved the sound quality as well—fantastic customer service, responsive and accommodating. Area to improve - punch. Too small. Can't fit my IEM.
Great Quality
Great quality upgrade to my stock cables, feels and look great, and incredibly quick shipping!
Amazing Quality
I've been using this cable for over a month and I'm happy with my purchase
Nice upgrade for my Z06
Compared to stock cable of Z06, the 8-wire version of Epsilon gives a good upgrade while not changing the original sound signature.
Incredible Cable
I have cables that cost several hundreds of dollars and they pale in comparison to this. It is incredibly well made. Shipping was fast, too. Null Audio is going to be one of my go-to cable manufacturers going forward.
