Design –
The F9 is a striking earphone with a beautiful rippled design and two-piece aluminium construction. They are easily among the best-constructed earphones around $100 if not the best with finish and solidity that matches earphones costing several times more. Further yet, their smooth satin finish serves to accentuate the fascinating quality of their undulating outer face, creating a stunning visual package that belies its asking price.
Fiio have also carefully considered ergonomics when designing the F9. Though not especially compact, the F9 is a far from a large in-ear, about the same size as the Shure SE215, with long but low-profile housings that make them perfect to sleep on. The earphones also generate little wind noise when outside despite their rippled design.
Through smooth sculpting and longer nozzles, the F9 achieves nice fit depth and great stability in the ear. They were perfectly comfortable for me even after extended listening, forming no hotspots. That said, due to two internal vents, the F9 doesn’t quite isolate as well as some competing models like the Rose Mini 2 and Pinnacle P2 but they still block more noise than the semi-open F5, K3 HD and EN700 bass and will be sufficient for public transport.
Up top, the F9 utilizes a removable MMCX cable. Fiio were quick to note that the MMCX connectors are much tighter than those on the F5 before and that newer batches of the F9 have a slightly larger MMCX connector angle that permits the use of 3rd Party cables (where intial untis were a bit too tight). This enables users to swap the cable in the event of damage or upgrade to a superior unit in the future. That said, the stock cables are quite good, the remote cable is rubbery but serviceable while the balanced cable is genuinely compelling.
Both have well-formed pre-moulded ear guides that I vastly prefer over memory wire and the balanced cable has a nice loose braid that is exceptionally supple and soaks up microphonic noise. The cables also have an integrated strap that keeps everything organized. Otherwise, the cables are mostly well relieved, more so than the cables that came with the F5 and the connectors are tight without intermittency.

Hola Ryan,gracias por las revisiones tan buenas que hace,es un placer leerte.me gusta le Mini2 ( tengo un Hifiman RE400 muriendose por el cable,pero que me puede decir de los nuevos Ibasso it01,mismo precio,y el Brainwavz
B400,un poco maas caro pero con 4 drivers,Gracias y un Saludo.
Hi Mike, I’ll buy you both, your loving wife Anezka
Hello Ryan,
I´ve been thinking of getting my hands onto the pair of Fiio F9. Up until now I´ve been using the V-Sonic GR07 but they seem to approaching its final days. So now it´s a toss-up whether to go the unbeaten path and grab the Fiio ones or opt for the tried and tested V-Sonics. What would you think or could you perhaps recommend me some other IEM somewhere in the vicinity of 150$ (200$ at the most)?
Cheers,
Mike
Thank you for answer. I used HiSoundAudio Wooduo 2 before they broke up. I temporarily bought the KZ ZS5, which sounded much more audially to me, but they are too big for my ear. That’s why I’m looking for headphones like KZS5 but with a smaller body and better made. I originally thought up to the limit of $ 100 (Fiio F9 and Oriveti Basic), but maybe I would raise the limit to $ 300. Here we are talking about Oriveti New Primacy, if they sound like KZ ZS5. What would you recommend a similar sound to KZ ZS5?
Thank you very much Ryan.
Hi Filip,
I enjoy both, they have excellent build and fit but the Oriveti isolates a bit more and is smaller. The Fiio is more V-shaped with considerably more clarity and more forward treble. The Oriveti is smoother and more laid-back but still sounds quite crisp, it has a warmer sound with more neutral body where the Fiio is clearer but thinner and raspier. Both are quite bassy, the Oriveti is more defined and visceral due to a sub-bass focus while the more mid-bassy Fiio has a little bloat and less extension. Let me know if you have any other questions!
Thanks,
Ryan.
Hello, Ryan,
please could you make some compare between F9 and Oriveti Basic? Thank you a lot.
Hi joa,
I don’t think the K3 Pro stacks up to its updated counterparts, but the HD is very comparable to the F9. The HD is a little more mid-recessed but its treble isn’t as thin as the F9 and it’s more detailed as a result. Both are a little muddy within the bass but the HD has a more natural midrange due to its more even midrange/treble transition. Both are built well and fit comfortable but don’t isolate superbly. I would personally pick the HD if you don’t eQ, the F9 has potential but you can’t maximise it from every source so I can’t freely recommend it like the Magaosi.
Cheers,
Ryan.
Hi Ryan, I’ve been reading your reviews on both magaosi k3 pro and hd.
I’m wondering , does the magaosi even compare to the f9?
Since its in the same price bracket, there wasn’t much comparison between both.
There certainly are a lot of iems out there, many of which I haven’t heard!
Regarding drivers, I try not to generalize performance to driver type though they are linked to an extent. To my knowledge Sonion and Knowles are the two main manufacturers, Knowles make the majority of audio related armatures, sometimes to spec for specific manufacturers while others employ off the shelf components. Some add some tuning on top, but a lot don’t.
We’ve certainly made developments in recent years, unfortunately, a lot of these advances come with price hikes. The Dunu is still a fine sounding earphone, I don’t think any of the $100 in-ears outperform it on a technical level. I’m inclined to recommend the Magaosi K3 HD, it’s a bit muddy and resolution isn’t exquisite but it is easily the most detailed and balanced V-shaped earphones around this price. If you’re looking to spend a bit more, Dunu’s new DK-3001 is sonically exceptional and many users have had more luck with comfort than Pinky and I.
I should not that I’ve thrown out these recommendations based on the fact that you enjoy the DN-2000. If you give me your preferences like Tom has below, I can be more specific. I don’t think you’ll find an “upgrade” around this price per say, but you may very well find an in-ear that better matches your subjective tonal preferences.
Cheers,
Ryan.
Is there an IEM you would recommend that is in the sonic quality range that the DUNU is? The IEM market has become so crowded, which is not a bad thing since it drives competition, makes it incredibly difficult to pick one!
It seems to me, while I may be wrong, the better sounding hybrids use knowles BA drivers but I’m interested to know your opinion.
I haven’t heard the DN-2000 for quite a while so I can’t provide direct comparison. I remember it performing on a higher level sonically though the F9 is definitely better in terms of ergonomics and comfort.
Ryan,
How would these Hold up in comparison to something like Dunu dn-2000?
Excellent. Many thanks for your helpful advice.
I had already shortlisted the mini2 based on your impressive review (even though I misnamed it the hero2 in my first post, lol)
It’s probably between the mini2 and pinnacle P2 in that case, and I’m edging towards the mini.
Regards.

No worries Tom,
I honestly admit that I have no insight into music production but I’ll try to help you out as best I can. As far as tuning goes, there aren’t a whole bunch of models around this price that offer genuine neutrality. That’s a reason why I’m such a big fan of the Rose Mini 2, it is easily one of the most balanced, neutral earphones around this price besides the notorious RE-400 though the Rose is far better built. For reference, it is way more linear than even the Pinnacle P2, it’s almost neutral but a little warmer and slightly more laid-back which makes it nicely musical as well.
It also has an over-ear fit, a very good removable cable and pre-moulded earguides (not memory wire). It’s easy enough to drive and sounds consistent from most sources. It has no remote, but since the cable is removable, you can just swap in a cheap 3rd party remote cable. The design takes some getting used to, if you have especially large ears it may not be the best choice, but it is fully sealed so isolation is great. I should just put in a disclaimer that this earphone is genuinely quite neutral, not balanced as some people throw out there about other earphones, it will probably be leaner and more mid-forward than expected.
Cheers,
Ryan.
Hi Ryan,
That’s a very generous offer, thanks.
My needs are a little complicated as I want something that can do double-duty as both my everyday walk-around DAP and Spotify (smartphone) commuting IEMs, yet also perform as a fairly balanced and somewhat analytical monitor for the mobile music production I do on iPad when on-the-go (Cubasis, BM3 etc).
Ideally, I would be seeking..
– Over ear fit (memory cables a plus here)
– Good isolation
– Neutral (or sightly curved) frequency response
– Easy to drive
– Good Durability (removable cables a plus)
– Remote-enabled cable option would be a nice bonus
I am currently using a cheap pair of Brainwavz B100 (single BA), which I feel really perform high above their $40 price, but I’ve been eyeing an upgrade for months now, considering many of the fine models you’ve been reviewing lately, such as the Pinnacle P1/P2, Hero2, Kinera, TFZ, Fiio, etc.
Is there anything you could suggest that might help me?
Many thanks
Tom
Hey Tom,
I could definitely make one but it would probably just be a compilation of all the reviews I’ve already written. Personally, I’m against a numerical ranking or scoring and I would prefer for people to find the model that best suits their personal needs and preferences. You’re more than welcome to contact me either here or PM on head-fi if you’re looking for suggestions.
Cheers,
Ryan.
Thanks for another great review Ryan.
Any chance I could encourage to compile a $100 IEM shoot-out? It would be a great help to me, and others, who need help navigating the sudden explosion of competition at this price point.
