2. How many drivers does the FH9 have? What is the included cable?
[Driver configuration]]
The FH9 is 1 dynamic 6 BA driver design (7 in total) with a 2nd generation 13.6mm DLC diaphragm dynamic bass driver fully capable of extending to the lowest frequencies with ample punch. All 6 BA drivers in each ear unit of the FH9 are from Knowles. High frequencies are handled by the proven SWFK-31736 driver. For the mid frequency drivers, FiiO has partnered with Knowles themselves in over 2 years of extensive research on how to best implement such drivers to achieve perfect harmony between multiple drivers for an absolutely coherent sound.
[Included cable]]
Included with the FH9 is a high-purity pure silver cable with 8 branches of 28 wires each, for a total of 224 wires. Each wire is individually isolated and all are braided together in the Litz style. The outer sheath of the cable is made from environmentally friendly TPU, which not only sports a radiant transparent look but is also resistant against yellowing under long-term use and stiffening when in low-temperature environments.
