FiiO F9 Triple Driver Hybrid In-Ear Monitors with Detachable Cable Design, Black

1 Dynamic Driver & 2 Balanced Armatures for Triple Helpings of Rich Sound

The F9 utilizes a hybrid design in which each channel is composed of one dynamic and two balanced armature (BA) drivers. The 9.2mm dynamic driver is specifically tuned to produce bottomless lows while the two BA drivers precisely portray extended upper-mids and highs.

Freely Switch Between Balanced and Single-Ended with Standard MMCX Connectors

The F9 utilizes the standard MMCX connector for its interchangeable cables, and comes standard with both 2.5mm balanced and 3.5mm single-ended cables.

Colossal Energy from a Tiny Body

You would never imagine that such a grand sound could come from something as tiny as the F9. Due to the way we have cleverly packaged the naturally-detailed BA drivers and the traditionally vast-sounding dynamic driver, we have achieved a fully cohesive sound that you would normally not think is possible from a puny in-ear monitor.

Organic Strength

The ripple-like lines on the F9 not only give it a unique touch, but also serve to ensure structural strength and maximize the amount of space internally for a more optimized design overall. Moreover, the inside layer of the F9's shell is specially lined with plastic to both better secure the drivers and eliminate internal resonances.

3.5mm Cable

The 3.5mm single-ended cable comes with a full set of in-line controls capable of playing/pausing songs, switching tracks, volume adjustment, and even calls with its high-quality microphone. This makes the F9 a perfect complement to enhance your experience with your portable audio player or cell phone.

2.5mm Cable

The 2.5mm balanced cable is made of silver-plated copper wire, which ensures a balanced sound signature and a high level of detail retrieval. Of course, due to its balanced nature, the left and right channel wires are separated so that there is significantly greater channel separation - leading to a richer, more detailed musical experience.

Over-the-Ear Design for an Enjoyable Experience

After much testing and feedback from a wide variety of users, we came up with an over-the-ear design that is not only ergonomic but also comfortable. With the F9, you can easily get lost within your music for hours without fatigue.

Hi-Res Audio Certification

The F9 has been certified by the Japan Audio Society to be "Hi-Res Audio" capable. This means that the F9 is capable of a frequency response up to 40kHz, which can fully reproduce the audio and give you a natural and life-like listening experience that truly lets you listen to the music the way the artists wanted it to sound.

PEK Polymer Nanocomposite Driver for Heightened Detail

The F9 utilizes a dynamic driver made of PEK (polyether ketone) polymer nanocomposite, known for not only being tough but also being light. This allows the F9's dynamic driver to be highly capable of producing quick, detailed, and extended bass.
