Hear its thunderous roar

The new 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

The FD7 comes standard with three pairs of interchangeable sound tubes, each with a different inner diameter for different sounds. Red tube – boosts bass, achieves deeper insertion in ear canals when working with bi-flange or triple-flange ear tips. Black tube – presents detailed treble with high resolution. Green tube – presents great treble details in every music note.

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.
