FiiO FT1 Pro Overview. Engineers have constantly strived to achieve a thinner and lighter diaphragm for planar drivers. After two years of independent R & D, FiiO has created an advanced one-micron, ultrathin diaphragm, using high-performance PET as the substrate.
Precision Engineering: With a 1μm ultra-thin PET diaphragm and a dual-coating of sapphire and aluminum, the FT1 Pro ensures enhanced frequency response, improved audio resolution, and a detailed sound reproduction.
