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.
The FD7 comes standard with three pairs of interchangeable sound tubes, each with a different inner diameter for different sounds. The red tube boosts bass, the black tube presents detailed treble, while the green tube achieves deeper insertion in ear canals when working with bi-flange or triple-flange ear tips for rich ultra-highs details. * The black tubes were pre-installed on the earphone units. Other tubes are included in the package.
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.
