FF1 is the latest entry model of the FF series, which has been developed with FIIO's earphone development know-how to explore new possibilities for intraconcha earphones in today's world where in-ear earphones have become mainstream. FF1 follows the technology used in the higher-end models FF5 and FF3, such as the large-diameter 14.2mm beryllium-coated dynamic driver and the adoption of an acoustic resistance tube to enhance the low range, to express heavy bass and mid-to-high ranges with a sense of openness.
