FiiO FA9 Universal IEM Review
FiiO FA9 Universal IEM Review
Fiio is a Chinese HiFi brand that was established in 2007 and has experience in researching and developing countless portable music products of different types, and sells FiiO-branded products through sales agents worldwide.
The FiiO FA9 is the new flagship model of the FA Series which is the Product Line with a “Pure Balanced Armature Driver Configuration”. The FA9 offers some interesting features like 6 Knowles Balanced Armature Drivers per monitor, a DLP Printed Monitor Shell, a sound tube system that is 80.6mm long, 3 Sound Adjustment Switches, an 8-Strand SPC Cable and many more.
I would like to thank FiiO for providing me the Fiio FA9 as review sample. I am not affiliated with FiiO beyond this review and all these words are reflecting my true and unaltered opinions about the product.
The actually price of the FiiO FA9 In-Ear Monitor is around $499.99 USD and can be purchased under the link bellow;
Package and Accessories:
The FiiO FA9 came in a relative big box similar in size like does of the FA7, FH5 and FH7 while the material and the look of the pretty thick sleeve box has changed. The sleeve box has now the FiiO brand logo on the top and shows a nice looking and colorful shimmering iridescent surface. The rear side of the box shows some technical information’s about the product and illustrations such like the new implanted 3 Switch Sound Tuning System.
When you put out the main box in black color out from the sleeve box you will see now the FiiO brand logo which is on the top.
This box contains the following items;
- 1 pair x FiiO FA9 In-Ear Monitor
- 1 piece x Detachable SPC Cable with MMCX connectors
- 3 pairs x Silicone Ear tips (Bass Tips)
- 3 pairs x Silicone Ear tips (Vocal Tips)
- 3 pairs x Silicone Ear tips (Balanced Tips)
- 3 pairs x SpinFit Silicone Ear tips (S/M/L) “one came preinstalled”
- 2 pairs x Memory Foam Ear Tips
- 1 pair x Bi-Flange Ear Tips
- 1 piece x HB3 Leather Case
- 1 piece x SK1 Magnetic Cable Organizer (can also be purchased here separately)
- 1 piece x Cleaning Brush
- 1 piece x Warranty Card and User Manual
The FiiO FA9 comes with the same luxurious leather case than we have seen with the FH7 which has the FiiO branding on the top. The case shows a high quality workmanship and can also be purchased separately.
The FiiO FA9 came with a very rich ear tips collection that is placed in a foam layer that is showing a short description about the sound effect and the size.
They are 3 pairs of balanced ear tips (S/M/L size), 3 pairs of vocal ear tips (S/M/L size), 3 pairs of bass ear tips (S/M/L size) and 2 pairs of memory foam ear tips (M/M/ size) and 1 pair of Bi-Flange ear tips (M Size) and 3 pairs of SpinFit Silicone Tips (S/M/L size)
The FA9 came also with some nice additions such like a small carry pouch with zipper that is made of fabric material, a nice magnetic cable organizer with FiiO Branding on the top and a cleaning tool that can also be used for the sound tuning switches.
I really like the richness of accessories that I wish to see also from the competition especially from the western based companies.
Design and Build Quality:
The FiiO FA9 is a multi BA IEM with a Semi-Custom Monitor shell which has 6 Knowles Balanced Armature Driver on each monitor and shows a 4-way crossover system.
The monitor shell is made of high transparency resin material with EU IIA medical certification that is skin friendly and antimicrobial that was printed with the 4th generation DLP 3D printing technology.
The FA9 is available in two different colors, which are the Clear and the Black variant which is the color of my review unit. The faceplate of the monitor shell has a so called “Diamond Cut” pattern which shows a nice beautiful dazzling effect if you look on it from different angles.
The in total 80,6mm long sound tubes and the other internals like the 6 BA drivers on each monitor are visible that I really like to see with transparent monitor shells.
The sound nozzle has a slightly angled profile with a mesh on the top that prevents the insertion of small partials like dust and other unwanted materials like earwax from entering in inside the sound tubes. I highly recommend you to clean the mesh periodically with the brush that came inside the box.
On the top of the monitor housing is the MMCX (Micro Miniature Coaxial) female connector that offers a tight fit with the male connector of the detachable cable.
At the rear side of the monitor shell are 3 sound adjustment switches that do allow you to choose between up to 8 different tuning options.
The FiiO FA9 comes with a detachable cable that has a 3.5mm headphone jack and MMCX (Micro Miniature Coaxial) connectors. The cable is made of 8 strands of high-purity monocrystalline silver-plated copper wire and features an environmentally-friendly transparent soft plastic insulation.
The MMCX male connectors are sitting pretty tight on the monitor and should last for years without any problem. The MMCX connectors have a transparent housing on each connector with Red (Right) & Blue (Left) color indicators in form of rings.
Near the MMXC connector housings are ear guides that do that do offer extra comfort.
The cable features a Y splitter and chin slider made of the metal material.
The 3.5mm gold plated single ended (TRS) headphone plug has a nice looking metal housing with L angled profile that we have also seen on previous FiiO cables.
The cable shows in general a very solid build quality and doesn’t have any annoying mixings or microphonic effects.
Fit and Isolation:
The FiiO FA9 is an IEM with a Semi-Custom monitor shell which offers a pretty ergonomic shape, while a comfortable fit depends highly on the selection of the right ear-tips which was for me the stock sized “S silicone tips.
The noise isolation of this FiiO FA9 is above average and worked pretty well for me in fairly noise environments such like a bus, metro or on some of my train trips.
The FiiO FA9 is a very easy to drive IEM with a pretty low impedance that varies between 13 Ω (in Low Impedance Mode) & 21 Ω (in High Impedance Mode) and has a sensitivity between 110 / 113 dB @ 1mW which makes it ideal for portable sources such like Smartphone’s, Tablets, Portable Players with a relative weak amplification.

The Sound Adjustment Switches:
The FiiO FA9 is an In-Ear Monitor that offers different sound signatures with the help of its “Sound Adjustment Switches”. Although the general sound character remains the same, changes can be made on the bass and treble frequencies. It can sound slightly bassier or more treble intensive with the help of these switches, while those differences are not very high.
- S1 switch on: lower impedance and higher sensitivity, making the FA9 easier to drive
- S1 switch off: higher impedance for a more clean and natural sound, with a darker background and lower audible noise from the source
- S2 switch on: Treble Boost
- S2 switch off: Reference Type of Treble
- S3 switch on: Reduces the Bass and does increase the Midrange
- S3 switch off: Does increase the Bass and does reduced the Midrange
The FiiO FA9 shows a soft, musical and fairly warm tonality from the top (treble) up to the bottom (subbass). The bass is pretty good in terms of speed and depth, the midrange is detailed and transparent while the treble range shows a good level of intensity and extension.
Please note that the FiiO FA9 review below will be based on the “Standard Mode” with switches set to “1 ON – 2 OFF – 3 ON”.
The FiiO FA9 has two BA’s that are dedicated to produce the lower frequency region and if the song/record shows deep bass notes the FA9 is able to reproduce them pretty well without to add too much coloration.
The subbass region of the FA9 shows a good intensity with sufficient depth and extension. It has in general a fairly warm and bold tonality, while it sounds pretty controlled without to be too boomy or muddy.
The subbass extension and quantity of the FA9 in songs like Lorde’s “Royals”, Photek’s “The Hidden Camera” and Twerl’s “Lishu” was satisfying and has also shows a good level of depth and rumble, while it is not on a basshead level.
The midbass region of the FiiO FA9 is pronounced and effective such like the subbass region while it is inferior in quantity. The midbass impact quite impressive and is suitable for almost any type of music genre, from electronic music up to faster genres with instruments like drums in metal music.
Instruments like drums in intros of Michael Jackson’s “Billie Jean”, No Doubt’s “Hella Gut”, Opeth’s “Windowpane” and U2’s “Sunday Bloody Sunday” are pretty fast, pronounced, detailed and full bodied.
The bass shows in general a quite good performance in terms of technicality, resolution and layering thanks to the well-tuned balanced armature drivers. The bass is higher in quantity for analytical presentation while it is a bit low to be on a bass head level.
The midrange of the FiiO FA9 shows in general a warm, smooth and fairly transparent tonality, while the level like airiness or clarity is above average. The midrange resolution of the FA9 is pretty fine for its price range.
The FiiO FA9 is a successful In-Ear Monitor in terms of intensity, extension, detail retrieval and transparency of female vocals thanks to its good upper midrange tuning. The general tonality of female vocals is fairly warm, musical and emotional and doesn’t shows any negative situations like sibilance or sharpness and is pleasant to listen to from female vocals in electronic music up to jazz tracks.
The FiiO FA9 is also a successful IEM when it comes to clarity and detail retrieval of male vocals. It doesn’t shows any negative conditions like muddiness or mixings, while the lower midrange tuning gives male vocal a soft and musical tonality. It sounds quite successful and enjoyable from vocals like Dave Gahan, Leonard Cohen up to Eric Clapton and Sting.
The FiiO FA9 offers a musical, close to warm, soft and smooth instrument presentation. Instruments do sound pretty detailed and airy and do have a good level of separation and intensity.
