About

About Null Audio

Null Audio has crafted IEM and headphone cables by hand in Singapore since 2008, today from our workshop and showroom on Playfair Road. What follows is how it began, in a university dorm room, and the thinking behind our name.

Our story

How it started

Long before there was a workshop, there was a student who could never leave things alone. Kevin, our founder, had a gift for building things from an early age, and it found its natural home in the computer engineering programme at Nanyang Technological University (NTU). Across coursework and design projects in circuit design, embedded systems and robotics, he was invariably the one at the bench: soldering circuit boards, building electric motors, writing and debugging code, flashing firmware onto microcontrollers, and bringing the robots to life.

He was, in equal measure, an audiophile, and no cable that came in the box had ever done justice to his headphones and IEMs. So when the cable on his Ultimate Ears Super.Fi 5 Pro failed in 2008, during his second year, an off-the-shelf replacement was never a serious option. He built one himself, copper from end to end, and voiced it to his own taste. In doing so, he inadvertently made the world's first upgrade cable for the Ultimate Ears Super.Fi 5 Pro, Super.Fi 5 EB and Triple.Fi 10 Pro.

Word spread quickly through Singapore's Head-Fi community. Fellow enthusiasts arrived with broken UE cables in need of repair, or with requests for an upgrade built entirely from scratch. His dorm room became a workbench of sorts: a soldering iron, an assortment of wire, and a set of moulds of his own making, in which he cast each plug from hot-melt plastic and set the pins in place by hand.

Before long, the requests were crossing oceans. Audiophiles in Japan and the United States, desperate to keep their treasured Triple.Fis in service, found their way to a dorm room in Singapore. What had begun as favours for the community had, almost without anyone noticing, become a small business.

Kevin went on to join Kenwood as an audio engineer, working in research and development on the company's two-way radios and digital audio solutions. His evenings, however, belonged to cables, built for dozens of different IEMs and headphones. In the end, he chose the cables. He took the work full time, and Null Audio was born.

Our team

Fellow audiophiles

He did not set out alone. Kevin brought together a small team from among his fellow audiophiles at NTU, people who shared his obsession with sound. Some of them have stayed at his side ever since, and remain part of Null Audio today.

The name

Why "Null"

Null is ∅: zero. Zero noise, zero haze, zero detail lost between your player and your IEMs. That clarity is what every Null cable shares.

On top of it, each cable has its own voice: copper adds weight and warmth, silver adds air and detail. A fine camera lens works the same way: perfectly sharp, yet it renders colour in its own way. Transparent first, then tuned to your taste.

Since 2008

Built by hand in Singapore

Null Audio started in 2008 making custom cables for Singapore's audiophile and portable hi-fi community. It still works the same way: every cable is braided, soldered and finished by hand at our workshop.
