FiiO FD3 PRO Black In-Ear Earphones,

Flagship-Level DLC Diamond Diaphragm Delivers Incredibly Powerful Sound: The FD3 Pro headphones leverage the many benefits of FiiO's dynamic drivers. The diaphragm is made from Diamond-Like Carbon (DLC), which is incredibly stiff and reduces unwanted distortion while remaining incredibly light, allowing the driver to deliver excellent transient response. The result is a driver with superior sound quality and minimal distortion, with the added bonus of being ultra-sensitive. [Breathtaking Flagship-Grade Acoustic Prism] The FD3 also features the acoustic prism effectively adopted in the flagship FD5, which delivers superior sound quality. Like the FD5, the acoustic prism system offers many benefits, including eliminating high-frequency standing waves, enhancing overall sound diffusion, and effectively resolving the time delay issue caused by the sound wave propagation path within the cavity. All of this translates to stunning sound quality. [Semi-open design for better sound, less fatigue, and reduced sound pressure]: Based on FiiO's patented technology, the semi-open design of the FD3 offers several benefits: not only does it provide a more natural sound, but it also effectively protects your hearing by balancing the air pressure inside the FD3, reducing pressure on your eardrums. 2.5D Film-Coated Glass Faceplate: The unique celluloid panel is covered in 2.5D film-coated glass for a pure yet fresh clarity. The aluminum-magnesium alloy body also makes the FD3 incredibly light, making it easier and more enjoyable to carry. The aluminum-magnesium alloy body is crafted using an industrial process that combines 5-axis CNC machining and hand polishing. [A Perfect Fit for You] The FD3 Pro comes with a dedicated cable made of high-purity single-crystal silver-plated copper, braided in the Litz Type 2 style with 19 wires in eight strands, for a total of 152 wires. The cable also features blue (left) and red (right) markings, and convenient audio plug interchangeability, allowing you to freely switch between 2.5, 3.5, and 4.4mm plugs depending on your source. With this cable, every note will be crystal clear.
