About FiiO
From its creation in 2007, FiiO has been pushing further and away to become one of the top players. And you know what? After more than 10 years of hard work, I think they achieved their goal as the once unknown brand is now on every mouth and ears.
Usually, I’m reviewing their players, like the M15, M11 Pro, or the M3 Pro. But, today, I’m bound to review one of their IEM’s, the all-new FiiO FH3, which fits just under the FH5 and FH7. A good upgrade from the previous F9 Pro? Time to find out.
The FiiO Series
FiiO FA1
The FiiO FA1 is the brand entry-level “balanced-armature” IEM. The soled driver is co-developed by FiiO and Knowles (who makes almost every driver on the planet) then packed in a pretty nice shell.
It’s not an IEM we had the chance to review yet, but the FH1 was pretty like by the audiophile community, so I’m sure we’ll try that one too. One day.
FiiO FH1
The FiiO FH1 is a hybrid entry-level IEM. It mixes a classic dynamic driver (10 mm titanium driver) with a Knowles 33518 to fully reproduce the full (hearable) frequency range. The shell is made of plastic, and not acrylic or metal, but nicely “nano-coated” to withstand daily use.
Berkhan reviewed it a few years ago now, praising FiiO for: “Great fit and good isolation, good content, nice build, and design, all together in a sub-100 package. FiiO managed to get a great mid-range performance from this IEM, thanks to the brass sound tube and Knowles BA driver right inside the nozzle”
FiiO FD1
The FiiO FD1 is another new IEM, neither hybrid nor balanced, it’s a pure dynamic driver, and that’s quite rare nowadays. At the heart of the ear, FiiO fitted a Beryllium-plated driver, with a two-way magnetic circuit capable of producing a magnetic field of nearly One Tesla.
Visually, the ear differs from the FH1 and FA1 again. Not that it looks bad or anything, but the 0.78pin seems a bit outdated compared to the MMCX socket we all come to adopt. That said, what matters the most at the end of the day, remains the sound. We’ll see when we get one!
FiiO F9 Pro
The FiiO F9 Pro sits right in the middle of the catalog. With two Knowles driver and one dynamic for the lows, it’s the jack of all trade most people will get. The shell is made of aluminum, the bundle is quite extensive, and the sound should fit almost every demand, in this price range.
Berkhan listened to it and said:” Well, this time for 139$, you get everything the F9 offers, plus a much smoother and controlled sound with better dynamics, precision and tonality, which is crucial in my book. Slight upgrades in terms of usage is the icing on the cake. What more can we ask?”
FiiO FH5
The FiiO FH5 is, in my opinion, the best option available in this price range. It’s still hybrid but gets more precise transducers, and this loveable magnesium-aluminum shell. It’s a bit punchy on the lower-end, but that’s what makes it lively too.
Again, Berkhan gave us his good word: “The guys at FiiO know how to improve themselves in this very crowded IEM market. They get better with each new product release, and they have finally presented a product which can be regarded as a serious in ear for audiophiles.”
FiiO FH7
The FiiO FH7 is, again, a hybrid IEM, which follows the same footsteps, carved by the FH5. It looks a lot like the FH5, sharing the same shell just in a different color tone, with more drivers and different tuning. It’s a tad more expensive, but as usual, the price difference makes a big difference in terms of performances.

FiiO FH7
Our boy, Berkhan, even put it in the recommendation list: “FiiO have finally managed to create an IEM that sounds correct, coherent and high quality this time around. And with its 450 $ price tag, it’s a wonderful IEM in the Mid-Fi area. I’m sure it will be a fan favorite in this price range soon.”
FiiO FA7
The FiiO FA7 is a traditional fully-balanced IEM. It fits right under the FH7, but above the FH5. No alloy shell here, but a very classy acrylic one, with a wave-shaped face plate. You get four drivers, and a slightly different sound signature, compared to the FH7 and FH5.
Berkhan reviewed it and gave good praises, with one little warning: “The FA7 impressed me the most until now. The only problem with its sound is the overpowering mid-bass and lower mid-region. Another small dent is the treble extension. Yet, the most impressive part for me is the instrument presentation. That separation and tonality simply blew me over for this price.”
FiiO FA9
The FiiO FA9 is the brand flagship, for now. 3D-printed shell, 6 Knowles Balanced Armature drivers, a whole new 4-way filter, and, most importantly, 3 sound adjustments. All of that, neatly fitted inside a glimmering diamond-like acrylic shell.
I reviewed this model a few weeks ago, so here is a snippet, for good measure:
“Think of it as the perfect blend of the FH7 and the FA7, but better: the sound stage is amazing, mids are great and all of that is neatly packed inside a cool 3D-Printed box of wonder. Going fully-balanced really did the job and that is one of the best options in this price range.”
FiiO FH3
Finally, we have the new FiiO FH3, a three drivers hybrid IEM which intends to replace the FiiO F9 Pro. Think of it as an entry-level premium model, with a CNC-milled case, S-Turbo acoustic design, and a whole new acoustic tuning.
So, with no further introduction, let’s see how it fares.

I’m not as enamored of its low frequencies as you are. I’ve used properly sealing Final E-Type silicones and Dekoni foams. The low end is lacking.
I do think it has a very nice, bright, holographic and presence-filled presentation. It’s lively and engaging. As much as I like it, I won’t be selling or shelving my Etymotics any time soon.

Hi, if you don’t consider the price, will you preferred this FiiO FH3 over the Meze Rai Solo?
Thanks

Thanks for your review 🙂
Can you compare the fh3 to the iBasso it01s? I have the it01s and would love to know if is worth to change to the fh3.
Best regards

I Just bought my first Dac Fiio M6
I just cant decide which IEM should I get. F9 Pro looks more confortable for a long time fit, But FH3 seens to have best construction and better sound. I do love trebles, and high vocals, but still love do keep the imaging. Which one should be my best options?
