    Lighter to release burdens from your ears

    The ergonomic design, combined with lightweight elements finally achieves comfortable-wearing feelings. With each unit weighing in at a mere 4.5g, it is put on your ears like it is nothing there.

    The loose and atmospheric bass, clearly transparent mids and high-resolution treble, are specially tuned with relatively balanced distributions. The overall tuning is a more popular style. Easy to drive and compatible with ranges of devices, the FD1 fully shows up the charm of music with details.

    The FD1 is certified by the Japan Audio Society to be capable of bringing you “Hi-Res Audio” with quality far beyond those of CDs.

    Hi-Res Audio Certified

    The beryllium diaphragm coupled with the two-way magnetic circuit design allows improved bass acoustic pressure and deeper bass explosion. Plus FiiO patented balanced pressure relief technology, the pressure is able to stay in a balanced state after precise counting and adjusting. All of these features ensure non-distortion for large dynamics, natural and elastic bass. You can comfortably enjoy hi-res music for a really long time with no burdens.

    Wins your heart by comforts even for long-time wearing

    Patented balanced pressure relief technology

    The dynamic driver is designed with an N50 two-way magnetic circuit having a 55% magnetic flux promotion and nearly 1 Tesla of magnetic field intensity compared with the traditional single magnetic circuit. The double magnetic flux activates forceful driven capacities that enable energetic, robust bass performances and even full and delightful transient responses.

    Two-way magnetic circuit design

    Powerful driven capacity

    Gold-plated retaining ring, stable vocalization unit

    The FD1 is meticulously designed with a gold-plated aluminium alloy retaining ring and sound tube for each unit, beautifying the FD1 and simultaneously providing way stable cavity for the audible unit, achieving incredible sound quality.   

    Included with the FD1 is the cable made of braided Litz wires, 30 cores per strand, 4 strands in a total of 120 cores. Each Litz wire is insulated from each other, ensuring better audio transmission performance under the naturally-occurring yet adverse "skin" and "proximity" effects. What this means for actual listening is improved bass, hauntingly realistic vocals, as well as obviously promoted sound quality.

    Higher-standard upgraded accessory

    4-stranded high-purity monocrystalline copper cable

    The faceplate is inlaid with rich-layer celluloid materials specially chosen for its unique texture and style, each of which contributes to the glossy FD1. Alongside with the low-key golden FiiO logo, the whole FD1 is coming with glittering and translucent light.
