The FiiO FD5 is a wired in-ear monitor with a 12mm dynamic driver using a beryllium-coated DLC diaphragm, a semi-open shell with a stainless steel faceplate and swappable sound tubes, and an MMCX silver-plated copper cable with swappable 2.5mm, 3.5mm and 4.4mm plugs. It suits listeners who switch between single-ended and balanced sources and want one dynamic driver they can tune with tubes and tips.

Who the FiiO FD5 is for

  • Single-ended and balanced sources: The cable's swappable 2.5mm, 3.5mm and 4.4mm plugs let one set move between a phone dongle and a balanced player.
  • Natural tuning: FiiO says it tuned the FD5 with reference to the Harman curve for a relaxed, natural yet transparent sound with a large soundstage.
  • Tuning and fit: The pre-installed large sound tube is balanced, while the included small tube is livelier and more bass-focused and pairs with the tri-flange tips.
  • Carrying it around: An HB5 storage case, a cleaning brush and an MMCX assist tool for removing the cable come in the box.
  • Skip it if: you need an in-line mic for calls: the included cable has none.

FiiO FD5 vs similar options
