    The Sound of Excellence

    The Headgear Audio 3.5mm to RCA Coaxial Digital Adapter Cable is purpose-built for FiiO digital audio players (DAPs) — including the X1, X3, X3II, X5, X5II, X5III, X7, and X7II — that output a digital coaxial signal through their 3.5mm port. Handcrafted in India with gold-plated connectors and a precision-wound PVC jacket, this cable lets you feed that digital signal straight into any RCA coaxial DAC or amplifier.

    This is a digital coaxial adapter — not an analogue line-out cable. It carries the S/PDIF bitstream from your FiiO player's 3.5mm coaxial output into the RCA coaxial input of your home or desktop DAC, bypassing your FiiO's internal DAC chip entirely. The result: bit-perfect digital audio with no re-sampling or signal loss, letting your separate DAC do the decoding instead.

    FiiO uses two different 3.5mm coaxial signal types across its X-series lineup — TRRS on the X3II, X5II, X7, X5III, and X7II, and TS on the original X3 and X5. Select the correct source variant above so your cable matches your specific player.

    Available in three lengths — 1ft, 3ft, and 5ft — to suit desktop stacks or longer rack-to-source runs. Each cable ships with a 6-month manufacturer's warranty against defects.

    This is a digital coaxial cable. Your FiiO player must support coaxial digital output via its 3.5mm port — confirm this in your model's manual before ordering.

    Important: The X3/X5 (original) use a 3-pole TS coaxial output, while the X3II and later models use a 4-pole TRRS coaxial output. These are not interchangeable — ordering the wrong variant will not work with your player.
