User questions & answers

Question:	Water Resistant
Answer:	Sweat resistant. Haven't dunked them, but I don't think water resistant. I can bike with them with no problem.
Question:	Your earbuds looks great. it supports aac and aptx, it even has 13mm drivers which is huge, but i see no reviews. will someone please contact me
Answer:	I have been using them for several months already. Honestly, I can think of no cons, battery time is close to advertised 9 hours (8-8.5 on average), despite the plastic the build quality is high, sound is as good as you can get in the bt earbuds and they sit comfortably and rarely fall out.

• 【HIGH PERFORMANCE】The 6 Knowles BA drivers per ear, together with the carefully-designed 4-way crossover and low-frequency ultra-long sound tube, completely covers the entire audible frequency range with a sound that will take your breath away.
• 【More lifelike sound】The FA9 marks the first time FiiO has employed Knowles EJ balanced armature drivers, commonly used among high-end IEMs. FiiO and Knowles collaborated to come up with the custom EJ-33877 driver for use in the FA9 for excellent mid-frequency performance with hauntingly realistic vocals.
• 【80.6mm ultra-long sound tube】The FA9 employs a specially-designed, ultra-long sound tube 80.6mm in length. The sound tube acts as a low-pass filter that effectively filters out unneeded extra mids and highs from the drivers to ensure a seamless frequency response. The sound tube also ensures the mid-bass is smooth and clean while enhances bass texture in general.
• 【3 sound adjustment switches, 8 possible sounds】The FA9’s use of electronic crossover technology allows you to tune the sound to exactly the way you want with 3 sound adjustment switches. The impedance, bass, mids and treble adjustment depends on what music you are listening or what your preferences are!
• 【REMOVABLE CABLE】Detachable MMCX design including a 3.5mm-terminated cable made of 8-strand monocrystalline silver-plated copper cable gives better audio transmission performance under the naturally-occurring yet adverse skin effect. What this means for actual listening are improved bass and mids, as well as more coherency between all audio frequencies.

Product features

DLP 3D printed

The FA7 is the first mass-produced, 3D printed quad balanced armature in-ear monitor, which results in remarkably consistent sound between pairs of FA7’s, as well as reduced sonic resonances that allow the music to flow through unimpeded.

Four-way crossover

In the FA7 is a painstakingly-tuned four-way crossover that allows the four drivers to work perfectly in harmony for an absolutely explosive sound.

Skin-friendly shell

The shell of the FA7 is made with German high-transparency resin which is both comfortable while also being extremely durable and resistant to discoloration.

No limits in design

Unlike traditional manufacturing processes with its inherent constraints, 3D printing allows us to fully realize our goals of creating an IEM that is both pleasant to wear and maximizes sound quality through an acoustic-optimized shell design.

4 Knowles balanced armatures

In each FA7 ear unit are 4 Knowles BA drivers. Bass is handled with aplomb by the CI-22955, mids are provided by the classic and proven ED-29689, and treble is produced by the dual-BA SWFK-31736 driver.

BA driver IEMs (FA7) vs hybrid IEMs (FH5)

They offer different types of sound, not that one type is better than the other. The FH5 is the warm, inviting gentleman that moves about with grace, while the FA7 is the bold younger brother with highly resolving nature and excellent transient response which provides an alternative exciting experience that complements the one found in the FH5.

Inspired by nature

The texture of the FA7’s shell recalls water ripples that naturally come with turbulent waves or from gently flowing streams and the colors take inspiration from nature too – choose from Red of the fiery sun, Blue of the vast seas, Black of the quiet nights, or White of the full moon.

Beautiful and elegant style

After having gone through countless ideas and revision, the FiiO design team came up with the final 3 complex, yet visually-arresting designs.

Comfortable wearing

After sampling thousands of different ear models around the world, we have finally been able to come up with an IEM with comfort that rivals those of custom models. It’s so comfortable that you will forget you are even wearing them.

MMCX connector

The standard FA7 cable is made of high-purity monocrystalline copper-plated silver wire and is also detachable and replaceable with an MMCX design.

Hi-Res Audio certified

The FA7 is certified by the Japan Audio Society to be capable of bringing you “Hi-Res Audio” with quality far beyond those of CDs.

13 pairs of ear tips

Included with the FA7 are 13 pairs of ear tips, covering balanced, bass-emphasized or vocal-emphasized sound signature as well as foam ear tips. With the FA7, get the sound signature you want by simply switching to the ear tips right for you.

User questions & answers

Question:	does the usb connect through a pc to operate
Answer:	Hi, thank you for your inquiry. The USB is for charging.You use the 1/8" stereo jacks to operate.Visit our store - TheCameraBox - The Best Electronics Source with a Warranty on all Items!
Question:	can it be hook up to a stereo system
Answer:	Using the headphone out into a mini to 2 RCAs you could. Why? If your stereo doesn't have a good DAC, or your car has an AUX it would improve sound.
Question:	Does it come with a audio cord for phones
Answer:	When I got mine, the included cord was very short, about 1.5" long with right-angle 3.5mm plugs on both ends. I am not sure if this changed, since some of the earlier responses suggest the cord is longer. I found this to be too short for my needs and decided to buy a 6" 3.5mm cord separately.
Question:	Can the battery be replaced
Answer:	When the battery on mine failed, I bought an Anker PowerCore Fusion 5000 (on sale) for under $20 on Amazon. Plugged into the micro USB port on the amp, it effectively replaces the much smaller internal battery. It's not elegant but it works well.

User questions & answers

Question:	Will this work with x5 iii
Answer:	No it only works with Fiio x7
Question:	Does balanced really sound better. I'm not sure if it's worth putting a new plug on my '4 wire' cable or not
Answer:	It might depend on the headphones. I only use this for In Ear Monitors and I think it sounds better. The balanced amp is not as strong as the other amps, but I think it sounds better. A little more refined. The balanced will also open up the soundstage.I hope this helps.
Question:	for the audiotechnoica m50x headset, would a fiat x5 or x7 be better? sorry for the novice doubt
Answer:	on paper, X7 has better hardware and changeable amplifier. with these headphones,you might not be able to tell the sound quality difference between X5 and X7 at all.
Question:	Has anyone tried this connected to a vinyl player? I'm only concerned about its ability to drive the headphones. Thanks
Answer:	It is poorly built and I wish i never bought it. Started shorting out the headphone potsBOTH od them!! about 6 months after i bought it. Piece of junk. Don't bother. Buy a old used receiver from a pawn shop for $30 and use that.
Question:	Does the E9 work standalone or does it need the E7/E17 to work
Answer:	Yes the E9 can work alone but you lose the usb functionality. You would also need to buy a L/R to aux cable.
Question:
Answer:	I'm pretty sure it is. If you can't use it docked into the E9 you should be able to connect it to the back of the E9 via 3.5. to 3.5 LOD. So it should be a non issue. But if you can use it directly into the Doc like the E7 was able to then that would be even easier. But to my knowledge you can't use the bass boost when it is docked (if the E07K has this feature).
Question:	Does anyone know the connections on the back besides the rca and the 3.5mm what kind of usb is that
Answer:	on the back there is a line in, a pre_ouput, rca right and left out, gain switch, usb in, and power in

User questions & answers

Question:	I never could get my se215 iems to stay in my ears. Are these larger or smaller? Will these be a more secure fit
Answer:	I am unfamiliar with the SE215 IEMs you mention, but the FiiO F9 IEMs fit very nicely. They come with several different silicone ear pieces and the wires are curved at the ends to help the headsets stay in your ears. I have not experienced any difficulty with these falling out of my ears even when I work out.
Question:	Where can I order foam tips that come with F9 Pro
Answer:	If you contact Fiio they will usually send you more or another accessory for the cost of shipping, and they tend to be quite generous. Sony makes a hybrid foam tip that is similar, as well as Shure and Westone.
