F9 Triple Driver In-Ear Monitors With Detachable Cable

The FiiO F9 is a triple driver hybrid in-ear monitor that uses where each ear channel is composed of one dynamic driver and two balanced armature drivers. The 9.2mm dynamic driver is specifically tuned to produce bottomless lows while the two, American made, balanced armature drivers, from Knowles, precisely broadcast upper-mids and highs.

The Knowles dual balanced armature gives the F9 immense detail and the dynamic driver is made of PEK (polyether ketone) polymer nanocomposite, which is known for producing extended bass while being rugged and light-weight.

With a frequency response up to 40kHz, the F9 has been certified by the Japan Audio Society to be “Hi-Res Audio.” This means these earphones give you a natural and life-like listening experience that reproduces audio the way the creators meant for you to hear it.

The F9 comes with interchangeable 2.5 and 3.5mm balanced, single-ended cables and a whole host of other accessories designed to tailor and safeguard your listening experience. For instance, the F9 comes with three different kinds of silicone ear tips, each designed for a particular sound signature in small, medium and large sizes; and three pairs of foam eartips. The F9 also comes with a waterproof carrying case, and water-resistant neoprene carrying pouch, so you can be rest assured that your earphones will continue to function for years to come.
