Features

  • HIGH PERFORMANCEThe 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 soundThe FA9 wired headphones 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 tubeThe FA9 earphones 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 soundsThe earbuds FA9s 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 CABLEDetachable 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.

  • Search is finally over, love these!
Color: Black
I don't consider myself a high-end audiophile, so my review isn't going to contain all those fancy terms trying to describe the sound of these (plus everything is subjective), but I will explain why I love these. I have extra sensitivity to the 2KHz-8KHz frequency range compared to most people and it has made buying headphones a nightmare for me for many years. With most flat response headphones, the 2-6KHz range sounds super exaggerated to me and is extremely fatiguing, so I tend to prefer the typical a V-shaped response to compensate. However, I find the V shaped response is super exaggerated on most consumer headphones and they just have too much bass and/or treble for me sometimes. I've been looking to purchase some IEMs and have tried a bunch of different brands/models, but could not find any that I really liked. It seems most IEMs either had too much bass, too much mids, or too much treble, or some combination of those. The ones that did have the frequency response I liked unfortunately didn't have enough clarity and sounded muted or muffled overall. Normally, I do not spend this much on headphones, but I got really desperate and decided to try these since they have the custom crossovers. They sound absolutely perfect to me! With the built in cross-over switches and the different ear tips, I was able to find the perfect balance in the frequency response and these have great clarity too. I can finally listen to music again for hours without hearing fatigue! Only complaints (minor): 1) Could not get the vocal tips to actually stay on the IEMs. They would just pop right off (I think they were too tight). This wasn't a problem for me as I didn't want them. Additionally, you can boost the treble with the crossovers anyway, so not sure if those tips are even needed, but mentioning it just in case. All the other tips worked fine. 2) These IEMs do not have a shapeable wire coming out of them to curve around your ears like most IEMs have. Instead they have a short (~0.5") curved plastic piece to direct the wire up and then have an preformed flexible plastic sheath to help curve it around your ears. I'm split 50/50 on that design. It's nice as it reduces a failure point of those constantly twisting connections that other IEMS have, however because the curved wire is not shapeable, I can't shape it the way I like and the sharp curve rests against the top part of my ears. I find the cord can sort of pull on my ears just a bit if I'm moving around and this can create an uncomfortable pressure point where the wire is touching. This isn't all the time since I usually use these sitting at my desk or lying down, and overall I find these IEMs very comfortable for their size, but felt it should be mentioned. In summary, if you don't mind the price, these IEMs are absolutely great and can be tailored to just about any listening preference! ... show more

  • Sound Quality is Shockingly Good
Color: Black
Upon reading the reviews of these IEM's, I figured I'd pick up a pair to demo and try. Upon unboxing, first thing I noticed was the quality of the packaging, which distinctly has that Apple quality of packaging. The included hard case is this leathery material that I LOVE, and the sheer amount of tips included for the IEMS was awesome to see- I settled for SpinFits as they work best in my ear canal. WIthout further ado, onto the actual review of the product itself... :) The FiiO FA9's come with a really nice cable that is comfortable around the ear, although I do wish there was an option to have a 4.4 mm balanced cable shipped with my pair instead of the standard 3.5mm unbalanced cable shipped with every single pair- because I'll have to purchase that extra. The earbuds themselves are solidly constructed and feel like solid hunks of custom-molded resin that one would put into their ears at a concert/shooting range for ear protection. Compared to my Massdrop Plus Universal IEMs, I like the fitment a little more. However they do not compare to the stainless steel construction of the Pinnacle Audio P1 IEMs of mine. As for the audio, all music was lossless vinyl ripped to FLAC files played from a high-end DAC/Amp connected to my computer to ensure maximum quality of audio signal. Out of the box and without any break-in, the FA9's had more clarity, detail, soundstage and richness than all my IEMs- the FiiO FA9's have many technologies found in multi-thousand dollar IEM's. When listening to some John Coltrane music, I was able to tell precisely where each instrument was (good imaging) and truly felt like I was the recipient of a private concert. In all, the asking price may seem high, but the product that is delivered ought to be priced much higher given the sheer quality. Will probably buy another pair as a gift. ... show more

  • Tunable, Comfortable, and under $500? Value city.
Look, this isn't an objective value. It isn't. You don't need $500 IEMs. You can find some straight monsters for under $200 all day. Also, it's not my job to list those for you; feed yourself and all that. HOWEVER, if you're looking for value in the mid range of pricing but performing like a higher-end product, well then, welcome. The FA9s are just that: monsters of value. From the packaging to the contents, even before you get to the sound, you realize Fiio have tried to inundate you with constant reminders that they appreciate your investment. And they don't take that for granted. Because after you consider all the tangible wonder that arrives with your diamond plated 3d printed little buddies, you have the utmost pleasure of putting them in your ears. Three switches to tune the impedance and sound. On a $500 product. It's so good. I'm not going to tell you what you should do. You should tell you yourself. Suffice it to say, Topping's A90 makes these sing as does the Lightning-to-3.5mm DAC from Apple. Appropriately present in vocal and midranges as you'd expect. Yes, like others, I'd prefer more attack and slam, though, with the Bass ear tips on and the 3rd switch 'Off', I'm not missing anything. And that's my point: Whatever sound signature may saunter in your head these will do it and then some. Bright and effortless. Comfort beyond belief (I've had them in for up to 14 hours so far) and they just keep showing up and doing what's asked. Only real life bummer is the lack of balanced cable in box. Man, that would've been amazing. Hell, want extra credit? Throw a balanced 2.5mm with a 4.4mm adapter. BUT FOR $500 WHAT WOULD YOU EXPECT? And that's just kind of it. You get so much, they perform so well, that when you consider what IS available for $500, you can't get mad. You smile. ... show more
