2. How many drivers does the FH15 have? What is the included cable?
The FH15 is a one-DD three-BAs earphone. The dynamic driver adopts a newly developed 10mm carbon diaphragm driver. The FiiO exclusive custom Knowles ED-30262 is used in the midrange and the two Knowles RAD-33518 are used in the treble.

The FH15 comes with a 152-wire silver-plated monocrystalline copper cable featuring 8 strands of Litz-braided wire. The Litz braiding specifically reduces the skin and proximity effects, leading to reduced eddy current losses and thus improved high-frequency resolution. Additionally, the audio plugs are swappable, and included are 3.5mm/4.4mm plugs.
