2,373

FiiO has garnered a lot of appraising for their flagship single-Dynamic IEM, the FD5. It featured a beryllium coated+DLC diaphragm for high-quality performance. Their “FD” series consists of two products the entry-level FD1 and the flagship FD5 until today. Today, FiiO has launched two new IEMs to bridge the gap between FD1 and FD5, the all-new FiiO FD3 and FD3 Pro. Both the FD3 and FD3 Pro are basically the same set of earphones with the Pro variant coming with a better cable with replaceable termination plugs. FD3 comes packed with a 4-strand 120-core monocrystalline copper cable with a fixed 3.5mm termination while the FD3 Pro comes bundled with a high-purity silver-plated monocrystalline copper cable with replaceable termination plugs. It includes 2.5mm+4.4mm Balanced and 3.5mm single-ended plugs in the package.

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.

Patented Air-Pressure Relief Technology:-

FiiO has designed the FD3 and FD3 Pro with their own patented air-pressure relief technology. This benefits the listeners to have a comfortable listening experience even during extended hours with a comfortable wearing experience. Enjoy listening to your favorite music without fatigue with the FD3 and FD3 Pro.

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.

Premium Aluminum-Magnesium Alloy Build:-

FiiO FD3 series of IEMs are made with exceptionally lightweight aluminum-magnesium alloy material with a unique celluloid face panel that has a 2.5D glass coating for a rich, premium finish with the pair. They completely have a rich, flagship-grade look that is extremely comfortable to wear and beautiful to show around.
