    Our story

    Singapore, since 2008

    Why Null Audio

    Null Audio began in 2008 with a broken cable, a dorm room at NTU and an all-copper replacement tuned to taste. The bench has since moved to Playfair Road in Singapore, and the work has grown from in-ear monitors to full-size headphones, but the premise has held. The name is ∅, zero: nothing lost between you and the music. Whatever character a cable keeps, the warmth of copper or the air of silver, is there because we chose it.

    The workshop

    Every cable is braided, soldered and finished by hand at #01-03 LHK2 Building, 76 Playfair Road. The same address serves as our showroom, and walk-ins are welcome on most weekdays.

    The conductors

    A cable’s voice begins with its metal. OCC and UP-OCC copper lend body, silver-plated copper and our hybrids trade some of that weight for air, and the gold-alloy flagships sit at the summit. Wire, strand count and gauge are printed on every cable page, because a cable you cannot read is one you are asked to take on faith.

    The fit

    An upgrade that will not seat is an expensive coil of wire, so the connector comes first: 2-pin, MMCX, IPX, A2DC and FlexiPlug for IEMs; dual 3.5 mm, mini XLR, LEMO and the rest for more than 400 headphones. At the other end, 3.5 mm, 2.5 mm, 4.4 mm, 6.35 mm, XLR, USB-C or Lightning, whichever your player asks for.

    The guarantee

    Each cable carries a one-year warranty, and a headphone cable that does not fit is remade free within 30 days of delivery. Any cable built from our options, at 1.2 m or longer, may come back within 14 days, less a 30% restocking fee for a change of mind, or be exchanged at no fee; inline-mic builds, shorter cables, interconnects and custom IEMs return only for quality issues. The return conditions give the detail. Damaged by accident, or failed after the warranty? Our Lifetime Replacement Program replaces it new at half price.

    The delivery

    Shipping is free by EPAC wherever it is available, and free by FedEx International Priority once an order reaches USD 250. Within Singapore, SingPost or Lalamove will bring it to you.
