Muffled garbage
Pros: - Non fatiguing sound signature (C'mon this is really a stretch.)
- Looks?
Cons: - Bloat fest
- Recessed upper mids
- No treble extension
- Poor technicalities
- BA timbre
- BA bass
- Waste of any money
This set somehow received hype when it came out a few years ago (I'm guessing Zeos hype.)

FA7 is almost complete garbage IMHO, the only thing missing here was a random upper mids / treble spike which would round out the awfulness of the FA7.

I dread to think how the infamous Shozy Ceres and Effect Audio King Arthur sound like, both graph like a worse FA7.

Perfect One Trick Pony - FiiO FA7 IEMs Review

FiiO FA7 is, from the start of this review, a one-trick pony, but a really good one. It is priced at 300 USD, and its main competitors are FLC 8N, FiiO FH5, and HIFIMAN RE800 Silver, in the light of the fact that RE800 Silver is priced at about 300 USD at this moment.


FiiO requires little to no introduction, they are one of the largest audio companies from China at this moment, they really know what they are doing, and they are putting out products with friendly price points, good performance and good build quality, like it's no effort. The warranty is usually excellent, and they will help you solve your issues, especially if you purchase from a trusted local dealer. Overall, if you need good quality, reliability, and good support, FiiO is the way to go.

It should be noted that I have absolutely no affiliation with FiiO, I am not receiving any incentive for this review or to sweeten things out. I'd like to thank FiiO for providing the sample for this review. This review reflects my personal experience with FiiO FA7. Every opinion expressed is mine and I stand by it, the purpose of this review is to help those interested in FiiO FA7 find their next music companion.

About me


First things first, let's get the packaging out of the way:

The nice part about FiiO is that they never fail to package their products in nice boxes, and to include a nice number of accessories and extras. Excellent carrying case, huge number of tips, including foams, ad a unique presentation, FiiO has it all.

What to look in when purchasing a high-end In-Ear Monitor

Build Quality/Aesthetics/Fit/Comfort

Let's start with the build quality, because those things are two little tanks. Of course, plastic tanks, but still, this is something.

FA7 comes with MMCX connectors, they are a bit tight, but alright for general usage. You can always strap in a silver cable that would compliment their overall sound a bit more than the default cable.

I love the way the shells change their colors when they are exposed to sunlight, despite being rather simple and black in color.

Now, the comfort, is typically FiiO. Or rather, FA7 is even better than FH5, FH5 was a bit short and didn't work well with everyone's ears, well FA7 is longer and sits even better in the ears. All FIIO IEMs to date have been quite excellent in ergonomics, and to be honest, FA7 is as well, there's absolutely nothing to complain about when it comes to their comfort, fit and isolation. Oh, I didn't even start talking about the isolation, which is, in one word, excellent. In fact, you've never seen this level of isolation from IEMs this casual, FA7 is an ALL-BA IEM, so it does provide more isolation than FH5 or FH7, both of which have driver vents for their dynamic drivers, where FA7 doesn't require any of those.

You should note that it is much simpler to write about something when you do have complaints, but with FA7, I have zero complaints about their build quality, fit and comfort. The cables have ear guides, but those are not hard, but rather are the soft type, making FA7 easy to fit with any ear.

The wearing style is over-the-ear only, so there is no cable microphonics at all.

Pretty much FA7 is perfect in build quality, aesthetics and comfort. They look cool, fit well and are comfortable to wear for long periods of time. For their 300 USD price point, I couldn't find better IEMs for aesthetics, fit and comfort, and the fit / comfort is universal, I had a few friends try them, and they all agreed this IEM fits well.

Sound Quality

The title gives it away, but FA7 is a one-trick-pony IEM when it comes to their sound. This is not something negative if they really fit your musical preferences. The sound of FA7 can be described as thick, lush, organic, musical, rolled off in the treble, and overall bassy, impactful.

The bass is pretty much the highlight of FA7, with a strong presence in the lows, a visceral sub-bass that rattles everything, and which will compliment anything that is electronic music, pop, or commercial music. I found the lows to be a bit overwhelming for most metal and rock music, and the same for most J-Rock and Japanse music, as the bass overpowers the vocals and the sweeter parts. On the other hand, I couldn't stop using FA7 while listening to anything Hip-Hop, and even with REOL, I felt they did her justice to the overall composition.

The Midrange of FA7 is a pretty thick and dark-lush one. There is a bit of a recess in the lower mids, and there is a slight bump in the upper midrange, so female voices are complimented a bit more by FA7, but I can't say for sure whether the better part are the textures or the nice dynamics of FA7, because in both, it is pretty good. The soundstage is average in size, and for a warm and thick sounding IEM, this is very good, most large-sounding IEMs are those who sport a brighter, more airy top end.

And now, that we reached the top end, the treble, I gotta say, if anything about FA7 did disappoint me personally, it is their treble. I mean, it is buttery, smooth, and fatigue-free, it is the kind of treble you could listen for, for hours, and it has that beautiful sparkle to it that many of your will surely enjoy, but at the same time, it is the kind of treble, that for me, at least, gets boring after a while, it is rolled off past 7 kHz, and this means that you don't get quite that much energy and life, instead, you get a buttery presentation that compliments poorly recorded music, but doesn't have a lot of sparkle and air, which is pretty necessary for rock, metal and J-Music in general.

Surely, the entire sound is unique with FA7, but man, if it fits your tastes, you'll have a hard time pulling it out of your ears and doing anything else, because they will make your days really sweet.

Portable Usage

So, compared to the Build Quality part of the review, where I typically rant about build quality / fit issues, in the portable usage part I tend to want to rant about how portable the product in the review actually is. The point here is to say whether I would use the say product on-the-go, and have fun, but then again, you will need to wonder if I'm a reliable source of information for that, as I do use HIFIMAN Sundara outdoors without fear (this is a joke).

With FA7, you have a medium rigidity cable, which means that you can easily use them outdoors, without having to worry about cable tangles, but also without having to worry about the cable being too rigid.

The ear guides are soft, which means that they will adjust to your ears, and since there is no cable microphonics, you could say that the cable is perfect for portable usage.

In terms of drive-ability, FA7 is easy to drive, but slightly sensitive to hiss. Most sources will do just fine, like FiiO's own M6 ultraportable DAP, but you would be better off if using something a bit better, since FA7 does scale a bit more, so a DAP like FiiO M9 would compliment them better.

Overall, they are a very portable IEM, and I have no complaints about their portability either.


Themain competitors for FA7 are FLC 8N, FiiO FH5, and HIFIMAN RE800 Silver. There are way more worthy competitors in this price range, so I picked the ones most people asked about in comparison to FA7.

FiiO FA7 vs FiiO FH5 - Starting with one that's pretty obvious, let's talk a bit about FH5 vs FA7. The comfort is better on FA7. The build quality is similar, but the comfort surely fits better with FA7. The sound is actually pretty different, FH5 is much more midrange-forward, and although FH5 is also pretty thick, FH5 tends to be a bit hot in the lower and upper midrange, compared to FA7, which is pretty smooth and thick. The overall signature is also leaner, cleaner, and less textured on FA7. The bass is deeper, stronger, quicker and more satisfying on FA7. Overall, even though FA7 doesn't have enough treble, I prefer it over FH5, despite the fact that FH5 makes an excellent IEM if you enjoy a mid-centric sound sometimes.

FiiO FA7 vs FLC 8N - FLC8N is an IEM that's unique actually, with a TON of possible signatures, a huge soundstage and an incredibly good build quality. In fact, if it was more widely available, I think that FLC8N would overtake a lot of its competitors in the 300 USD price range. Now, starting with the package, 8N wins hands-down, but this is also because it comes with all those filters, bells and whistles, otherwise the two would be pretty much equal. When it comes to the sound, FLC 8N is a chameleon, but in none of its configurations it isn't quite as thick, smooth and warm as FA7, so if this is your kind of signature, you should totally check in some FA7. Another thing to consider is that in terms of comfort, I felt like FA7 was a bit more comfortable, although both disappear in your ears, wearing them in cold weather made FA7 feel much better, as 8N is a metallic IEM and would gather some condensation bubbles, which made me quite uncomfortable with using it during Winter.

FiiO FA7 vs HIFIMAN RE800 Silver - Now that RE800Silver is at a similar price with FA7, I thought to myself, why not compare them. I know that a lot of you have been asking about this comparison, so let's skip the package, which is much better for FA7. In terms of build quality, I trust the two equally. HIFIMAN has an excellent service and support lately, and so does FiiO, and both IEMs are built really well. In terms of comfort, RE800 Silver is considerably more comfortable than FA7, as it touches your ears much less and is pretty much a no-contact IEM, compared to FA7, which is a full over-the-ear IEM. In terms of sound, the two are quite different, FA7 is very thick, lush, lacks treble, is relaxed, fatigue-free, and kind in its sound. RE800 Silver is much more revealing, more detailed, more textured, is much brighter, has a more sparkly top end, is cleaner, and more focused on details, but also inherently more fatiguing. I prefer RE800 Silver for Metal, and Rock, for example, but I can see the appeal of FA7 with pop, electronic and downtempo music.

Recommended Pairings

For the pairings part of this review, I will go with FiiO M6, FiiO M9 and xDuoo X20.

FiiO FA7 + FiiO M6 - Now, FA7 is very easy to drive, so a DAP like FiiO M6 should totally do them justice, and with this you're set for a small and convenient setup that you'll enjoy greatly, so you don't have to worry about rocking FA7 with just M6. The signature of M6 is mostly neutral, complimenting FA7 rather well, as I would suggest not pairing FA7 with any smooth or warm sources, since they are already plenty warm and smooth. There is some hiss with this pairing.

FiiO FA7 + FiiO M9 - FiiO M9 is another great example of a good pairing, as M9 is much more detailed than M6, and FA7 has the resolving abilities to showcase it, with more textures in the music, a wider soundstage, and since we're talking about the DAPs themselves, M9 also has a much more competent system, at least when it comes to its driving power. If you have a larger IEM or Headphone collection, you should explore a bit with M9 rather than a mini-DAP like M6. There is very little hiss with this pairing.

FiiO FA7 + xDuoo X20 - xDuoo X20 is an excellent example of a good DAP that really suits FA7, as X20 was very bright in my experience, and it would complement the signature of FA7 quite well, signature which was very smooth and warm. Overall, this is one of the best pairings I've heard, especially if you need no bells and whistles, and if you prefer physical buttons over a touch screen. There is some hiss present with this pairing, and X20 is not absolutely black in its background with FA7.

Value and Conclusion

So we finally come to talk about the value of FA7 from FiiO. You know, at some point I feel like I don't even need to do this part for FiiO products, man, they are all great value. And this is not me speaking as a reviewer, but as a customer, in general, FiiO stuff has good value, and holds the said value, if you have an older FiiO DAP, you know you have a gem. FA7 is no exception, it makes fierce competition for other IEMs in the 300 USD price range, provided you like the kind of signature FA7 goes for.

In terms of package, you get a wide selection of tips, you get a nice carrying case, and the IEMs, all presented in a rather large box. You get a really well made IEM, with a good cable, that bears no microphonic noise, and is flexible enough to be good, but not too wiggly. You get excellent comfort and isolation, and you get a reliable product, that even looks good even though it is fully made of plastic.

In terms of sound, FA7 is a thick, warm, L-Shaped IEM with a ton of bass and power, but without much treble, it may get boring if you were looking for a bright signature, but it will be like butter for your ears, if you wanted an IEM that really is fatigue-free and warm / thick sounding. Really neat for those looking for this type of buttery, clean signature.

At the end of the day, if you want an IEM that is well built, clean, comfortable, comes with everything you may require, and which sports a thick, lush, warm and fatigue-free signature, you should totally check out FiiO FA7, and don't forget its other sibling, FiiO FH7, which I will be reviewing soon as well.

@Dobrescu George Not a big deal really, I had a pair of FH1, not an expensive IEM. I am actually more sorry that some people will think twice before buying a Fiio product not because of the products itself but because of the awful customer service they have. Once again great review, cheers.
These kind of suck without EQ, too warm for my taste.

Headphoneus Supremus
Pros: Build quality, included accessories, wearing comfort, isolation, stylish looks
Cons: Too much bass emphasis bleeding into mids. Recessed highs. Intimate soundstage. There is no included balanced cable options must buy separate at 128€
A little about me

I'm an audiophile but not the Graphs and number ones, more of a music lover type of audiophile who seeks the best true sound quality. My Genre of choice is Classical music from renaissance to Classism and abit of nationalism like Grieg, Dvorak.

Unboxing, packaging & accessories
The Fiio FA7 come packaged on a black carton box with a sketch of the product in white, model name in white bold font on the lower left corner, on the right lower corner the Hi-res Audio logo.

On the side of the mentioned box it is a scratch-to-reveal authenticity code. At the back there is more information of the product and the logos of the other manufacturers Knowles for the BA drivers and HeyGears for the 3D printing tech used to make the FA7.

Removing the outer packaging you'll get the inner package, and the one that contains the FA7 and its accessories. There's nothing worthy to mention there as it is just a black box, only at the front is the FiiO logo. Opening like a book cover you'll get presented with the FA7 on a foam cut out.

Below the cut out, there is an assortment of tips, a small pouch containing a cleaning brush and a magnetic cable organizer. Finally there is instructions and a pelican hard-translucent plastic case.

The tips include the normal silicone foam with the M size already installed in the FA7, the silicone come in S,M and L, they're called balanced ear tips, asidenit comes with just M sized double flange tips.
The foam tips, which resemble comply foamies, come also in S, M and L
Next we have Bass and vocal tips which also come on S, M and L sizes.
The iem comes with a standard 3.5mm stereo unbalanced plug and silver cable in MMCX connector.

Build quality, comfort and isolation.
The build quality of the ear pieces is just stunning, perfectly smooth and seem durable to me. It is not.plastic but a German resin of.medical grade properties. Additionally the shells are made with a 3D printer to.ensure homogeneous production.

Absolutely love the transparent shells that enable to view the internals. I chose the blue and red faceplates with abstract finish, looks classy and sometimes it reflects light in a cool way.

At below the mmcx receptacle, there are L and R markings aside the left shell is blue and the right red.

The cable is nice, made up of high purity silver according to fiio, it terminates in angled L 3.5mm unbalanced stereo. The isolation of the cable is transparent enabling you to see the wires. At the mmcx connector there is a pre-shaped ear hanger /hook
Which is pretty stiff and unlike the hooks of the sony IER-Z1R which they are smooth and supple. In general the cable feels stiffer than that of the IER-Z1R.

15653553278675332366347450320470.jpg 1565355344369428601165697376562.jpg 15653553675375765499410599469494.jpg 15653553852076133913739559888443.jpg
Wearing comfort is superb, better than the IER-Z1R, no pain here, no bulky feeling
Insertion goes deeper but I can feel vacuum seal a bit uncomfortable at times.

Isolation is simply top nicht, better than IER-Z1R (vented, the FA7 is totally closed off).

Sound Quality
My gear is a sony walkman NW-WM1A unmodded with 6500 playback hours since its purchase in 2016.
Additional HP I have a full size headphone the sony MDR-Z1R and another in-ear also sony, the IER-Z1R.

My music is only classical musical in lossless quality ranging from FLAC 16/44.1 to DSD 11.24896 MHz. I have no mp3 or aac and I dont support proprietary formats like. MQA which is really lossy/lossless hybrid alien.

In short summary the signature of the FA7 is tuned to the midbass and lower mid emphasis , giving it a warm but veiled signature with an intimate soundstage.

For the use I'll be giving to the FA7, commute in public transport (Germany) I won't be whining and crying that they must sound like the summit-fi IER-Z1R.

Stock sound analysis: medium sized balanced tips, SE stock cable.

BASS: the bass dominates the signaturex especially the mid bass giving it a hollow sound signature, too much bass makes string quartets sound too woody and grungy (Beethoven string quartets - ABQ - EMI - 16 /44.1 --- Bach Goldber variations- Canerata RCO - challenge records - DSD 11.2MHz) veiling the violin and viola. Orchestral music sound too bassy and reverberate it reminds me of this MEGABASS from early sony discmans (mozart Youth symphonies -
Pentatone /Phillips - sir Neville Marriner - DSD 2.8MHz & Zelenka the orchestral works - CPO - FLAC 16/44.1) overall presentation of large orchestral works.feels cramped.

Mids: while these sound lush they are marred by the bass bleed giving a lack fo resolution female and Male vocals can sound too in your face and shouty (Tallis the complete works - brilliant classic - flac 16/44).

Highs: they lack sparkle and excitement , at least they aren't shrilly, but can't.make up to the hi-res standard , the micro detailing is there but one must Equalize it. (Cesar Frank organ works , Audite, DSD 2.8MHZ , also in DSD64 Bach the four great toccatas and fugues - sony / Columbia records , E. Power Biggs)

Tip rolling sound analisys.

The double flange sounds like the stock tips but a bit more distant in sound. Bass in the subbass gets.more presence,, still hollow sounding.

Foam tips,.one of the best I think,.gives a nice subbass punch and add.more clarity to highs, stage is reduced some how sounding small.

Bass tips, the worst for the FA7. It only increases the veil the FA7 possesses, treble and mid energy get reduced and all detail and micro resolution is lost. Giving them a pretty bassy signature akin to having clogged ears with air /water .

Vocal tips: remove some.of the veil and midbass giving a bump in details and resolution, still sound a bit hollow tho, but they have more bass control and less flabby bass sound, more punchy.

Sony IER-Z1R Triple comfort tips: these new sony tips are an hybrid between silicone and foamies
They increase the bassiness and make the FA7 sound muddy but less shouty, like the fiio bass tips the FA7 on the sony TC tips sounds muffled.

Sony IER-Z1R silicone tips;
The sound improves even better than the vocal tips by fiio , the midbass is reduced, controlling the bass, but there is more midrange, especially lower mid accentuating a bit the hollowness at times, but overall clarity is improved, stage increases a bit they want to sound big like the IER-Z1R but still intimate.

I dont want to.make a comparison with the IER-Z1R, different price ranges and sound signature, feel it will be unfair. So will just give a short summary : the IER-Z1R has.more micro detailing, sprkliwr highs and organic mids, bass is more on the subbass but more controlled and physical feeling to it. The stage in the Z1R is also gargantuan , colossal , they have a stage like speakers or open cans.

FA7 is darker veiled and the sony IER-Z1R is more natural , lush organic sounding, even it comes as bass light after hearing the FA7 for a while.

But the FA7 are undoubltly great commute IEMs when you want isolation, sont care about sound because train or road noise.

* Great build quality
* isolation is top notch
* wearing comfort
* accessories, (sony really baffled me there with no cleaning tool for the Z1R)
* sound good when properly EQ
* stylish and cool looking.

* Bassy and hollow signature, making it veiled and not so resolving.
* intimate soundstage
* prone to tip rolling and perhaps cable rolling.
* stiff cable materials
* no included balanced cable. (Sony does include a 4.4mm in the cheaper options)
* must equalize to sound good
* performance not up to the price



New Head-Fier
BA only, no DD? It will be interesting to get a listening impression. I can only imagine the bass will be technical but lacking significant punch. Who knows, maybe I'll want to play with them instead of the FH5? Don't keep us waiting!

I was going to buy the Fiio FH5 and equalize them to increase the Highs but then this bad boys came
I'm hyped to see a review, maybe they are my first earphone purchase. Hating my 10$ ones xDD
