10mm beryllium-plated dynamic driver

With FiiO's typical flagship-grade headphone technology, the FD1 headphone dynamic driver is made of high-end beryllium, known for being light, thin yet extremely rigid. It brings you a sense of movement and power, shaping majestic sound performances.

N50 two-way magnetic circuit design

The FD1 earphone 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. The double magnetic flux activates forceful driven capacities that enable energetic, robust bass performances and even full and delightful transient responses.

Patented balanced pressure relief technology

You can comfortably enjoy hi-res music for a long time with no burdens.With FiiO patented balanced pressure relief technology, the pressure is able to stay in a balanced state after precise counting and adjusting.

Unique celluloid faceplate

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.

Gold-plated retaining ring and every tiny detail

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.

4-stranded high-purity monocrystalline copper cable

Included with the FD1 headphone 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.

Great sound with good machine

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.

Lighter to release burdens

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