FiiO FD1 In-Ear Monitor with Beryllium-coated Dynamic Drivers

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. 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 can stay in a balanced state after precise counting and adjusting. All these features ensure non-distortion for large dynamics, natural and elastic bass. 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. The loose and atmospheric bass, clearly transparent mids and high-resolution treble, are specially tuned with relatively balanced distributions. Easy to drive and compatible with ranges of devices, the FD1 fully shows up the charm of music with details. 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.
