      DLC Diaphragm Dynamic Driver

      The latest FD3 series of IEMs boasts a large 12mm dynamic driver unit with full-DLC diaphragm material. DLC(Diamond-Like Carbon) is a highly rigid material that also has an extremely lightweight structure that reduces unnecessary vibrations and makes the driver more responsive and clean sounding. It uses strong magnets that produce a strong magnetic flux of up to 1.5T. This helps in a deep-diving lower end and a highly detailed, ultra-low distortion in the high-end frequencies.

      Featured Acoustic Prism In The Front Cavity

      FiiO FD3 features an acoustic prism in the front cavity. It is fitted close to the front end of the cavity. This helps in precisely controlling the sound waves travel inside the cavity, reducing high-frequency response, and provides an overall sound wave diffusion. It also helps in reducing the distortion in the output and enables the pair to produce a clean output.

      Better Sound With Semi-open Design

      The semi-open design of the FD3/FD3 Pro on FiiO's patented technology for balanced air pressure within brings several advantages. Not only does such a design lead to more natural sound. but it also effectively protects your hearing by balancing air pressure within the FD3/FD3 Pro leading to less pressure on your eardrums. This makes your listening expenenceless tiring and the sound less forced.

      Premium Aluminum-Magnesium Alloy Build

      The FD3/FD3 Pro has a simple, yet beautiful appearance based on the theme of curves. The unique celluloid panel is covered with Z5D film coating glass for a pure yet fresh transparent look And the aluminum- magnesium alloy of the body makes the FD3/FD3 Pro exceptionally light, making it easier and more pleasurable to carry around.The aluminum-magnesium alloy main body is made man industrial process combining five-axis CNC processing and hand polishing.

      Swappable Tunning Nozzles

      FiiO implemented the replaceable tuning nozzle in the flagship FD5 that is being followed here by the FD3 and FD3 Pro too. They both come with two sets of tuning nozzles, one with a thin diameter of the mouth and the other with a wide diameter mouth. The thin diameter nozzle benefits the lower end while the wide diameter nozzle benefits the high frequencies with the FD3 series.

      Difference Between FD3 & FD3 Pro

      While both the FD3 and FD3 Pro have the same cavity design and structure, the only difference between both pairs is the included cable. FD3 comes bundled with a 4-strand 120-core high-purity single-crystal copper cable with a fixed 3.5mm termination plug. FiiO FD3 Pro comes with a heavier, 8-strand 152-core Litz structure silver-plated monocrystalline copper cable with interchangeable termination plugs. It included 3.5mm SE, 2.5mm Bal, and 4.4mm Bal plugs in the package.


      Recently, an increasing number of customers have got to hear diverse news of FiiO's new earphones, the new force in dynamic line. Surprises and delights burst. Some asked that at such an affordable price, can it really make a phenomenal appearance? Some questioned whether it was really coupled with a full DLC diaphragm? Some wondered what are the other features other than the flagship-grade sound tube... All in all, it is kind of a new birth. This time, we would like to introduce our newly designed earphones with great sincerity, the FD3/FD3 Pro, the single dynamic in-ear monitors with a detachable cable to you.


      01/Not just a fresh face

      The 12mm large diaphragm of the FD3/FD3 Pro is made of Diamond-Like Carbon (DLC) which is both impressively rigid which helps to reduce unneeded distortion and vibration yet also surprisingly light. Inside the FD3/FD3 Pro's striking shell lies a driver with a robust magnet of 1.5 Tesla magnetic flux paired with an ultra-fine copper-clad aluminum Japanese Daikoku voice coil for an amazing, powerful sound.


      02/Jump to a new level with full presence of flagship-grade members

      The acoustic prism so effectively used in the flagship FD5 for great sound quality is also featured in the FD3/FD3 Pro. Like with the FD5, the acoustic prism system helps to effectively solve the problem of time delay caused by sound wave propagation path in the cavity. In addition, the semi-open design based on FiiO's patented technology for balanced air pressure within leads to a more natural sound even for long-time listening sessions. Overall, the FD3/FD3 Pro swears to break the rule of being an ordinary one, but struggling to a higher level.


      03/Upgrade to the FD3 Pro with an exclusive cable

      The FD3 has evolved to the FD3 Pro with an exclusive cable even with already excellent configurations and performance of the original one. The FD3 Pro comes with an exclusive cable made of high-purity monocrystalline silver-plated copper, with 8 strands of 19 wires each for a total of 152 wires braided together in Litz Type 2 style. In addition, the cable features interchange audio plugs, allowing you to freely switch between 2.5/3.5/4.4mm plugs depending on your source. With this cable, every music note has never been clearer!
