FiiO FD1 In Ear Headphones

Flagship-grade beryllium-plated diaphragm driver

With FiiO's typical flagship-grade headphone technology, the FD1 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.

Powerful driven capacity

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.

Wins your heart by comforts even for long-time wearing Patented balanced pressure relief technology

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.

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.

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.

4-stranded high-purity monocrystalline copper cable

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.
