FiiO FD3 PRO In-Ear Headphones, Black

FiiO FD3 PRO Earphones, High Resolution, 1DD In-Ear Monitor, MMCX Connector, Flagship Level DLC Diamond Diaphragm, Black 【Achieve Surprisingly Powerful Sound with Flagship Level DLC Diamond Diaphragm】The FD3 Pro headphones leverage many of the advantages of FiiO's dynamic drivers. The diaphragm is made of diamond-like carbon (DLC), which is extremely rigid and incredibly lightweight while reducing unwanted distortion, allowing the driver to achieve superior transient response. As a result, the driver, with its excellent sound quality and minimal distortion, is given the bonus of ultra-high sensitivity.

【Breathtaking Sound with Flagship Grade Acoustic Prism】The acoustic prism, effectively employed in the flagship FD5 to deliver superior sound quality, is also featured in the FD3. Similar to the FD5, the acoustic prism system offers numerous benefits, including eliminating high-frequency standing waves, enhancing overall sound wave diffusion, and effectively resolving time delay issues caused by sound wave propagation paths within the cavity. All of this contributes to superb sound quality.

[Semi-Open Design for Better Sound, Less Fatigue, and Reduced Sound Pressure]: Based on FiiO's patented technology, the FD3's semi-open design offers several advantages to its balanced air pressure. This design not only delivers a more natural sound but also effectively protects hearing by balancing air pressure within the FD3, reducing pressure on the eardrums.

[2.5D Film-Coated Glass Faceplate]: The unique celluloid panel is covered with 2.5D film-coated glass, achieving a pure yet fresh clarity. Furthermore, the aluminum-magnesium alloy body makes the FD3 extremely lightweight, making it easier and more enjoyable to carry. The aluminum-magnesium alloy body is manufactured using an industrial process combining 5-axis CNC machining and hand polishing.

[Personalized Enhancement]: The FD3 Pro comes with a dedicated cable made of high-purity single-crystal silver-plated copper, using 19 wires in 8 strands, for a total of 152 wires braided in a Litz Type 2 style. Furthermore, the cable features blue markings on the left and red markings on the right, making it convenient to swap audio plugs. You can freely switch between 2.5/3.5/4.4mm plugs depending on the source. With this cable, every note will sound crystal clear.
