FiiO Triple Driver IEM F9 PRO Carrying Knowles 30017 earphones launched in India

FiiO has launched a new pair of earphones at its Autumn Launch Event in India. The FiiO Triple Driver IEM F9 PRO Carrying Knowles 30017 has been launched at a price of Rs 12,990. 

F9 PRO – specifications and features

The F9 PRO utilizes a hybrid design in which each channel is composed of one dynamic and two balanced armature (BA) drivers. The Knowles dual balanced armature TWFK-30017-000 gives it “immense capabilities in resolving every last detail, which results in a powerful presentation of music,” according to the company.

The F9 PRO has a dynamic driver made of PEK (polyether ketone) polymer nanocomposite, which is tough and light at the same time. The IEM has a frequency response from 15Hz to 40kHz, thanks to its physics-driven design. It has also been certified by the Japan Audio Society to be “Hi-Res Audio” capable. 


The IEM utilises the standard MMCX connector for its interchangeable cables and comes standard with both 2.5mm balanced and 3.5mm single-ended cables. The 2.5mm balanced cable is made of a silver-plated copper wire. 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 calls.

Design-wise, the F9 PRO is apparently inspired by water. FiiO states, “the sleek lines recall the ripples that occur when drops of water fall into a lake, making the IEM both more human and familiar.” Whatever that means. 


The end of the MMCX cable’s left channel is blue, while the end of the right channel is red in colour – which makes it easy to identify the audio channels. 

The F9 PRO is a successor to the F9 and FiiO is leaving no stone unturned to garner the attention of all the audiophiles out there. You can get a discount of Rs 2,000 if you choose to order the IEM right away.
