FiiO FH9 Headphone Earphone Wired High Resolution Over-The-Ear 1DD+6BA MMCX Swappable Cable with 2.5/3.5/4.4mm Headphone Plugs for Smartphones/Laptop/Speaker/Home Audio(Black)

FiiO’s new flagship hybrid IEMs, the FH9 headset, are the result of two years of intense research on how to take full advantage of the strengths of hybrid IEMs and push the limits of how they can sound. This dynamic 1 driver 6 BA (7″ total) design features a 13.6mm 2nd generation DLC diaphragm dynamic bass driver fully capable of extending to the lowest frequencies with a wide punch. The mid and high frequencies are handled by a custom 6 Knowles BA configuration that accurately reproduces every last musical detail.
