INTRO
We are going to analyze the Fiio Fh9. An iem type headset from the Fiio brand. This headset for me has been the Flagship of the brand until the launch of the Fx15, a product that we will also see soon. But what is so special about this Fiio Fh9?
UNBOXING SECTION
Closed box (What do we have?), cable length and quality, connection.
When it comes to unpacking we have a huge amount of accessories. When I say huge, I mean huge. I tend to be one of those who prefer brands to focus on providing good sound and leave accessories aside. Let's be honest, most of us have a spare cable, tips of various types... but in the case of the Fiio Fh9 you won't need it. You have everything and of excellent quality. Perhaps it is one of the strong points of this product...although considering the cost of the headset, this number of accessories should be a norm.
The cover, one of the most important elements, is elegant and strong. The earpiece fits in without too much pressure, although it could have been a little wider. The design of this one seems sober and elegant to me, it doesn't have the most beautiful colors, but it does the job very well.
Special mention to the cable. 1.2 meters, high purity, 8 strands, 19 cores and modular. But the best thing is that it feels premium. It's not rigid, but not too docile either. Possibly the best cable I have seen stock in headphones of this type.
As if that were not enough, we have the possibility of modifying the sound with the tips and filters. Personally I don't notice obvious differences with the latter. I consider the stock filter to be the most complete, although I have read users who liked the green treble filter. I encourage you to play and try. As for tips, we have all types and sizes. SpinFit, silicone, double phalanx, memory foam...in addition, each of them allows the signature to be slightly modified. In my opinion, the vocal and balanced tips are the ones I like the most.
-DESIGN, insulation, weight and comfort
This titanium earpiece has a semi-open design. The latter is, theoretically, to give more spatiality and dimension to the sound scene...but we'll see if this is really the case or if it's more marketing. Its isolation, however, is not the best in its price range. In fact, I would say that items less than €200 can insulate more.
As for the design, we have one with a structure similar to that of the Fh5s. Personally, it has a very futuristic design, it is not one of my favorites, but I would say that I quite like it.
The headset has a higher weight than average, I suppose this is due to the titanium casing and its 7 drivers in each capsule. Even so, the comfort is quite good and it doesn't bother me during long listening sessions.
SOUND SECTION
The purpose of headphones is to listen to music. This Fiio Fh9 is tuned for a musical and domestic experience. Thanks to its tonal response it fits many different genres. Its semi-open design does not make it ideal for use in transportation or in crowded places.
The signature
Overall, the sound signature is balanced for me, especially if using the balanced tips and standard filters.
Fiio, with this headset, wanted to bring together the best of the Fd and fh series. Sonically, I would define the Fh9 as a very balanced iem in all aspects, versatile and without weak points. The bass is impressive and very punchy, the mids are clear and lively. They don't feel hidden or muted. The treble is tuned just right so that it is not sibilant, but has good extension giving enough air and liveliness to percussion, for example.
Will a powerful amplifier be needed?
In terms of amplification, only 18 ohms and 108 decibels of sensitivity make this set ideal to combine with a good DAC dongle. With 120mw at 32 ohms it is enough to move it practically at 100%.
I have not noticed a great sonic loss if connected to a mobile phone as I have seen with other headphones. So if you want to use it from time to time with a laptop or cell phone, it can be done without a problem.
SOUND SECTION – BASS
The texture of the bass is excellent, making it an ideal set for those who want good punch, definition and texture. It sounds gratifying and you won't want more in any song. The presence of the subwoofer is also evident. It doesn't seem to be difficult to go down to those frequencies, as I can see that it is difficult for other products.
It is not a dry and fast bass like the Oh5 but instead opts for a more viscous, pleasant and, ultimately, more musical sensation.
SOUND SECTION – MIDS
After the punchy bass, you'd expect the midrange to drop off noticeably, but that's not what happens on the FH9. Ha
and good clarity and cleanliness in the mids without having that noticeable body in the bass. If it had that body we would already be talking about a higher-end headphone at a tonal level. I perceive the voices only slightly further back, but with enough detail and presence to not appreciate a V shape.
Thus, we have a tone that keeps the sound signature fairly uniform throughout the midrange frequency response, although there is some emphasis on the bottom and top ends. At best, the midrange can highlight some details, but presents a natural overall response, with good dynamism and sufficient detail.
SOUND SECTION – TREBLE
The highs of the Fh9 are controlled and not sibilant. You can perceive a slight brightness that, to my taste, gives added liveliness to the sound. With the green filter this is enhanced even more, but it makes it not as versatile in genres.
It is not a referential acute, but it is musical. Let's say they occupy a dominant place in the sound signature without culminating in a distracting tone of penetrating harshness. This done so as not to bother anyone. The texture is quite good and, the body, yes the body of the treble... (I know that sometimes we associate this with the midrange)... well it is a little step below the oh5 but the FH9 gives more extension and clarity which benefits the listen for classical music for example.
SOUND SECTION – TECHS
From experience it seems that semi-open designs allow iems to give more depth than extension in the X axis of the soundstage. Did I expect more? Yeah. Above all, because we are looking at a €600 product. I honestly consider that its technical performance is not of this value considering that there are hybrid headphones for a lower price such as the DuNu Sa6 mk2, Mangird Top, Hype 4, which give more in this section...whether in resolution, separation or another area .
In fact, I consider that a good planar magnetic headphone can give equivalent technical performance. Now, I'm not saying it's not technical. No. It has good capacity, but I expected more.
Taking into account the Fh5s, this Fh9 provides a more three-dimensional and spherical scenario. This is not an IEM that deals with a linear stereo field, where the left and right positions extend beyond the earphone housing. The FH9 maintains a space that represents the spatial image, while providing air and good soundstage separation. The layers overlap well and it is able to place the sound elements in a realistic way although not as well or precisely as other sets.
The soundstage is very natural and focused on making sonic reproduction addictive rather than oriented towards listening to details, positioning and expansion of the soundstage.
SUMMARY SECTION
The Fh9 is one of those headphones that can serve as a flagship for most of us. Even so, I consider that the Quintet, a €250 headset, has a technical performance that is only slightly inferior to this Fh9, a product that is worth more than twice as much. Still, I think what this fiio does really well is playing with that balance between fun and technical ability.
Its pros? Without a doubt, its package full of accessories, the cable, and the construction give an experience that is appreciated and let's say that the economic investment hurts less. On a sonic level, I highlight its dynamism, bass section and natural listening without much color, but tremendously addictive.
Its cons? As I said, its technical capacity for this price does not make much sense today. I was expecting a more massive scenario...(also considering that it is semi-open), better image and a little more resolution... perhaps that is why Fiio has released the Fiio Fx15, a headset that curiously improves these aspects.
Even so, I consider that the Fh9 is tremendously complete.
I say goodbye, see you in the next video or review...
All the best.
