FiiO Pure Beryllium Diaphragm Moving Coil Unit Earphone - FD7

Pure beryllium diaphragm 12mm large dynamic driver | Exclusive color scheme Stainless steel MMCX connectors| 3 interchangeable sound tubes Semi-open acoustic design | Front acoustic prism High purity monocrystalline pure silver cable

Hear its thunderous roar

The new flagship 12mm pure beryllium diaphragm dynamic driver, due to beryllium  being 4 times more rigid than steel while only weighing ¼ as much as titanium, has 3 times the transient performance compared to titanium drivers for lightning-like  speed and thunderous explosive sound.

Master of the arts, FD7 exclusive color scheme 

The color scheme exclusive to the FD7 hints at its grand audio prowess, evoking ancient Chinese landscape paintings with a river of gold flanked by vast black mountains created by bold ink brushstrokes. And like master painters who use their years of accumulated experience to create such magnificent paintings, behind the FD7 is a culmination of the years of engineering experience to create an equally breathtaking soundscape. The FD7 isn't just a remarkable piece of art – it's thoroughly capable of creating art itself with its remarkably delicate and refined sound.

Angled MMCX connectors,achieve maximum wearing comfort

The cable of the FD7 was designed with angled expanded MMCX connectors which went through many ergonomic iterations and improvements in order to achieve maximum wearing comfort.

Multiple flavors with interchangeable sound tubes

Befitting of its flagship status, the FD7 comes standard with three pairs of interchangeable sound tubes, each with a different inner diameter for different sounds.

Miraculous comfort with volcanic fields

The ingenious "volcanic field" system developed by FiiO takes advantage of how sound waves work to noticeably improve its sound. The "volcanic field" reduces standing waves and distortion, and overall improves the diffusion of bass waves in the FD7. In addition, the FD7's semi-open design relieves pressure on the ear for more comfortable listening. All of this technology is wrapped in a beautiful design.

Fast as lightning with the help of a front acoustic prism

Close to the pure beryllium driver in the FD7 is an acoustic prism system that addresses issues that come with the time delay between different sound waves. It effectively changes and precisely controls the way sound waves travel through the FD7 to enhance how high frequency waves propagate and to ensure audio phases are correct.
