The F9 features a hybrid design in which each earphone is composed of one dynamic and two balanced armature drivers. The dynamic driver, which is 9.2mm in size, is specifically tuned to produce lows while the two balanced armature drivers produce extended upper-mids and highs. It F9 utilizes a standard MMCX connector for its interchangeable cables and comes standard with both 2.5mm balanced and 3.5mm single ended cables out of the box. The rippled design of the F9 is not only for looks but also serves to ensure structural strength and maximize the amount of space internally for a more optimized design. The dynamic driver is made out of PEK (polyether ketone) polymer nanocomposite, known as a tough but light material. This allows the dynamic driver to be capable of producing quick, detailed extended bass. Finally, the F9 has been certified by the Japan Audio Society to be Hi-Res Audio capable, which means that the F9 is also capable of reproducing audio up to a frequency response of 40kHz.
