Fiio FD1 Beryllium-Plated Single Dynamic IEM

Fiio FD1 Beryllium-Plated Single Dynamic IEM

• 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. That means 4 times more rigid than steel, three fourth lighter than titanium,and sound velocity up to 12KM/s
• An N50 two-way magnetic circuit design, powerful driven capacity, allowing 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.
• Included with the FD1 HiFi headphone is the cable made of braided Litz wires, 30 cores per strand, 4 strands in a total of 120 cores. Ensuring better audio transmission performance under the naturally-occurring yet adverse “skin” and “proximity” effects
