Following in the footsteps of the flagship FD5, the FD3 from FiiO are a pair of wired audiophile-class earbuds with a semi-open design and large 12mm dynamic drivers that provide a wide 10 Hz to 40 kHz frequency range. Sporting a Diamond-Like Carbon diaphragm and acoustic prism, these earbuds offer enhanced sound quality with a fantastic transient response. The FD3 not only sound great, they also look fantastic, thanks to a robust magnesium/aluminum alloy body and a hand-polished 2.5D film coated glass faceplate. Interchangeable sound tubes let you tune your earbuds for either enhanced treble or extended bass. The FD3 includes three pairs of balanced eartips, three pairs of bass eartips, and three pairs of vocal eartips, all in different sizes. The FD3 also includes foam eartips, a cleaning brush, two pairs of interchangeable sound tubes, an MMCX assist tool, a detachable audio cable, a balanced 4.4mm swappable plug for the audio cable, and a carrying case.
