FiiO F9 Pro Hybrid Triple Driver In-Ear Monitors Review

Author:Goh Beng Yeow
Share This Review:
Summary: The F9 Pro is possibly the most impressive IEM I have heard at this price point.

Achieving maturity in build quality and making efforts towards a better user experience, FiiO has demonstrated how much it has progressed as an earphone manufacturer within a short span of time. The impact the Knowles dual BA driver has made to the sound quality further justifies the USD 40 premium over the F9.

Fiio F9 Pro In-Ear Headphones Review – Triple driver on the cheap

Author:Josh Noriega
Share This Review:
There’s a lot to like with the F9 Pro. It’s not the cheapest pair of in-ears you’ll find, generally, but it is very competitively priced when considering audiophile-class headphones.

Soundstage (spatial perception) is one of the best aspects of the F9 Pro’s sound. It punches above its small in-ear weight, as sounds are generally space-filling about the head, and dynamics have some dimensional play.

Share This Review:
The Fiio F9 Pro sounds great out of the box with its quite detailed and balanced sound signature, has great ergonomic and a stylish appearance packed in a box with lots of accessories. Well done!

The Fiio F9 Pro is an airy sounding IEM with a relative wide soundstage.The overall performance for imaging and instrument placement is pretty good and is represented in a quite natural way.

Fiio F9 Pro Triple Driver Earphones Synopsis – Best bang for the buck?

Author:Josh Noriega
Share This Review:
We’re comparing it to earphones that cost hundreds more (because that’s what it aims to compete with). For the price, the F9 Pro is certainly where it should be. And the large bass and soundstage responses helps it stand above the rest.

Fiio has had such humble beginnings like this, but has stayed humble despite its progressions. Originally dedicated to audio players, Fiio made the natural step to producing its own headphones. And at $139 for a triple-driver flagship in-ear headphone, it shows that the company is continuing to challenge an industry that charges hundreds more for a comparable package.

FiiO F9 Pro vs 1More Triple Driver: which are the best triple-driver earphones for you?

Author:Ershad Kaleebullah
Share This Review:
On the same source, at the same volume level, the FiiO F9 Pro is a lot louder than the 1More Triple Driver. Moreover, the instrument separation or imaging is a much, much better on the F9 Pro clearly outlining its analytical capabilities.

The F9 Pro comes with two Knowles-branded balanced armature drivers and a single dynamic driver. To put it simply, the F9 Pro is touted to offer an improved sound signature over its predecessor thanks to these new armature drivers.

Review: Fiio F9 Pro In-Ear Headphones

Author:Guido Gabriele
Share This Review:
With excellent design and comfort, tons of accessories, and seriously good (if a little sharp) sound, the Fiio F9 Pro gets our strong recommendation.

We were very impressed with the F9 Pro’s sound. Its large dynamic drivers produce punchy, controlled, clear, bass with very deep extension; the F9 Pro is one of those headphones that provides impressive bass without sacrificing the rest of the frequency range.

FiiO F9 Pro - Harder, Better, Faster, FiiO

Author:DOBRESCU GHEORGHE
Share This Review:
All in all, FiiO F9Pro is one of the best IEMs there are for 150$, especially if you liked the original (F9), and if you are looking for something even more dynamic, more balanced, and very natural in its sound.

FiiO made an updated version of their well-received FiiO F9 IEMs, this time using High-Quality Knowles BA drivers, giving the entire sound a new definition. The Bass driver is the same, but with better BA drivers taking care of the midrange and of the treble, F9Pro is surely to sound different from F9.

I recommend at least trying F9 PRO, it’s worth your effort, I decided to keep them in my stable for a comparison with the next review candidates.

F9 PRO easily rivals IEMs from established manufacturers. Just a week ago I have listened to a pair of Shure SE315 and those sounded as if I had wool in my ears, the F9 PRO easily outperformed them by a long shot.

FIIO F9 PRO REVIEW

Author:Marcus
Share This Review:
The value is still excellent, perhaps even more so considering the physical changes. More premium BA drivers, double the amount of tips, additional left right coloring and a soft zip pouch for enhanced pocketability.

Performance wise it inherits the good parts of the F9 in terms of noise control, relatively easy to drive and very well built. It also becomes a more coherent and smoother sounding IEM with better midrange presence and a more balanced and less peaky top-end.

FiiO F9 Pro - "Mrs Knowles"

Author:HiFiChris
Share This Review:
The FiiO F9 Pro offers really good value, plenty of really nice accessories, has got nice features.

On the technical side, the F9 Pro is a quite convincing in-ear that sounds just like what you probably wish a hybrid in-ear to sound like at this price point – clean and crisp midrange and treble with good separation, together with a bass that has got somewhat more decay and less tightness compared to most Balanced Armature woofer implementations, while still sounding quite controlled, giving it a character that most people would refer to as “natural”.

Fiio F9 Pro In-Ear Headphones Review

Author: Tech Merit Reviews
Share This Review:
So, at a $40 higher MSRP compared to the regular F9, does the F9 Pro hold a higher bang-for-buck value? Erm, somewhat. At this price, the F9 Pro is in direct competition with, for example, the MEE Audio M7P. To be perfectly frank, the M7P doesn’t stand a

Compared to a far more neutral set of IEMs like the HiFiMAN RE-400, the F9 Pro’s v-shaped signature does become apparent. The neutrality of the RE-400 just sound more natural, and never do you get the sense that one part of the frequency spectrum is trying to compete with another. Despite that v-shaped response, though, the F9 Pro can still be said to have a reasonably well-balanced signature.

This is the best IEM FiiO have ever released so far, and I hope they continue to offer great value in this market.

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 F9 - Emotional Affordable Audiophile

Author:George Dobrescu
Share This Review:
FiiO F9 is priced very fairly, at around 100 USD, being one of the most accessible IEMs with a good quality to their sound and with an excellent build quality.

FiiO F9 is an amazingly good IEM produced by FiiO, while they tried to bring as much quality they could, at the lowest price point it was possible. After tinkering with many designs, they managed to create one nifty little IEM.

Both models are a great match for any of the FiiO DAPs, and scale up well if you wish to use them with a higher resolution source, yet they also work with smart phones and streaming media (as I discovered listening to Slacker Radio on my phone).

2017 was a banner year for FiiO, seeing the introduction of a bevy of new products.

Having now had the opportunity to use the F9 Pro for a week as part of this tour, I can say I should not have been reluctant to purchase the F9 Pro in the least. The F9 Pro easily ranks among the best in-ears I have tried in the sub $300 price range.

Bravo to Fiio for listening to customer feedback and making the changes. Fiio has done what some would have said was impossible, gone from startup earphone maker to class-leading performance in less than 24 months.

F9 Pro does everything well. And I learned my inventory of gear can not find a fault with the F9 Pro. It is that good.

I tried my hardest to find a weakness in the F9 Pro by using the gear that I have, but to no avail. I concluded either there is no weakness to be found or I simply need better gear to evaluate F9 Pro better.

The FiiO F9 PRO is a shot at Audiophiles who enjoy a detail filled listen with tuning that resembles the classic Sony EX1000 among others.

It feels like an aluminum peanut. It fits like a piece of hearing protection which is to say it fits really really good with the proper eartips which depend on your ear size.

FiiO F9 PRO to rewelacyjne słuchawki, które gorąco polecam. Spodobają się osobom szukającym detalu, rozdzielczości, ale także rozrywki. Łączą w sobie analityczność i muzykalność, a przy tym są uniwersalne.

Jeszcze nie opadł kurz po premierze FiiO F9, a już azjatycki producent wprowadził do sprzedaży wersję PRO. Od zewnątrz słuchawki są identyczne, a wewnątrz mają taką samą konfigurację przetworników, ale tym razem zastosowano armatury produkcji Knowlesa.

FiiO F9 Pro Review – Pure Clarity

Author:RYAN SOO
Share This Review:
The F9 Pro produces a well-sized stage that reaches to the periphery of the head but very rarely extends beyond. They combine great width with nice depth to create a multi-faceted if not totally immersive presentation.

I have no hesitation donning the F9 Pro one of the most technically impressive earphones I’ve heard around this price; achieving clarity through resolution, separation and air through extension and engagement through transience rather than relying on unnatural peaks and troughs.

It combines good build and design, great ergonomics, and well thought out accessories, with an exceptionally mature and balanced signature. I would unreservedly recommend the F9 Pro. In this price range, its going to be hard to beat.

FiiO has really pulled out some surprises with their IEM releases this year and the tweaks in the F9 Pro show the maturity FiiO is already reaching – even as a comparative newcomer to IEMs. The F9 Pro is a serious contender at a low price (almost entry point for some).

The price of $99 is remarkable for a hybrid triple driver. Throwing in balanced cables and very well machined build quality just goes to show that it is indeed possible to get great performance for not so many pennies.

Having visited them a few weeks ago and seen how they operate I am honestly not that surprised. They guys work really hard and what you see being launched was conceived months if not years in advance.

Taking into consideration the FiiO F9’s build quality, great overall QC, and exceptionally surprising refined sound signature, judging FiiO F9’s value is an incredibly easy task. Thus far we have not heard anything at the $100 point which sounds this damn

Fiio have also announced another upcoming iteration of the F9 – the F9 Pro. This has intrigued us tremendously, as it would be interesting to see what Fiio can do to improve upon the existing F9. We assume that they will get rid of the 7kHz peak; but what else?
