Read the full description

FiiO’s impedance adapters are mainly designed to pair high-power sources with low-impedance, high-sensitivity in-ear monitors. Plugged in between the two, they effectively reduce background noise and make the volume easier to set precisely, for a better listening experience. Choose 33Ω or 75Ω, 3.5mm single-ended or 4.4mm balanced, in a standard or “golden cudgel” finish.

FiiO impedance adapters: golden cudgel and standard versions, 3.5mm and 4.4mm, 33 and 75 ohms

Two finishes

  • Standard: CNC-machined aluminium alloy with an anodised finish for a refined texture.
  • Golden cudgel: CNC-machined aluminium alloy with raster laser engraving that shows off the intricate texture of the “golden cudgel”.

FiiO impedance adapters: 33 and 75 ohm versions, gold-plated connectors, 5000 plug tests

Made to last

High-quality gold-plated connectors give reliable electrical performance, the adapters passed 5,000 plug-in tests, and they work with a wide range of devices.
