This article is to refer on my consolidated experience with the first of the two most recently released final IEMs: A3000.

Introduction

As its company cipher, final puts a significant research effort in each product in the first place. A3000 has been conceived and developed as an evolution of their A series, which started last year with flagship model A8000. Always last year, the B range was also introduced by final.

According to final, both A and B IEM lines are different stems off a single base-concept: instead of trying to develop a mythical (read inexistant) “perfect all rounder” earphone, final considered how different types of music call for different presentation features, and went from there.

Sound design for these models has been undertaken with attention to the relationship between spatial impression and dynamic range of music, and the physical characteristics of earphones and headphones.
We have categorized sound creation on music recording onto these two axes: spatial impression and
dynamic range.

One way of thinking regards the distance perception. Classical and jazz recordings are thought to be performed with emphasis on aspects of spaciousness, such as sense of distance, broadness and reverberation. On the other hand, rock, pops and many of the recent animation soundtrack recordings, spaciousness is not as highly emphasized. There is thought to be greater emphasis on clarity, which brings the various instruments and vocals to the front.

Another approach is dynamic range – in other words, changes in loudness over time. If the dynamic range is wide, naturally it is possible to use the change in loudness over time to achieve a more dynamic expression of music. But, there are some types of music for which narrower dynamic range recordings are preferable to allow each of the instruments and vocals to ordinarily appear before the listener’s eyes.

The difference between these two ways of thinking pertains not to which is superior but rather differences in how music is composed and what is demanded of it. With regard to classical music, and that played by orchestra in particular, the spatial orientation of instruments is particularly important. Stringed instruments are positioned nearest to the audience with wind and percussion placed behind them.

Should the balance between the spatial orientation and volume of each group of instruments collapse, the music would disintegrate. For that reason, uniform clarity of sound that allows each instrument to appear before the eyes of the listener is not demanded of this type of music. Even for classical music, a string quartet, for example, would have a narrow dynamic range and the clarity of each instrument would be more prominent. For rock and pops on the other hand, spaciousness is not as necessary as for classical music, and so there is greater emphasis on clarity than spaciousness.

These preconditions are very important, particularly for earphone and headphone listening, and it has become apparent that the implementation of appropriate target curves and driver design result in deeper enjoyment of music.

TL;DR – for classical and jazz music soundstage and imaging are more important than single sounds definition; the opposite is true for pop & rock.

Moving ahead:

The development of the A series began with the establishment of a new evaluation method by analyzing the relationship between sound quality and physical characteristics, and the result was the A8000. The A3000 has further evolved that evaluation method. We listen to music recorded in different qualities at different volumes.

However, in the conventional evaluation method, it is common to perform subjective evaluation under the condition that the sound pressure that presents the sound is fixed, and it is difficult to judge a good sound that matches the actual product audition. Therefore, as a result of a new research targeting an evaluation method that matches the actual music listening situation, we believe that we were able to produce a product that can be said to be the definitive edition in this price range.

Less elegantly, more vulgarly explained: you like listening to AC/DC? You’ll surely want huge loudness similar to what you experience during one of their concerts. Now tell me: when did you ever encouter deafening high sound volumes (a.k.a. SPL) at a jazz club?

A3000 is not for extraloud, supermeaty, iron-strong AC/DC sound. Hard rock lovers: you can quit now 🙂

With A3000 …

Each note is localized so that it emerges with a contour in the low range that spreads slowly, and you can vividly hear the fine touch of the guitar and the delicate vibrato of vocals. Since you can notice the detailed nuances of the music, new impressions will be created from the playlists you are familiar with.

Quite poetic.

Is it exactly like that? Well not “precisely” like that at least for my ungolden ears, or maybe for my unplatinum gear, or both. But one thing is sure for me and is that A3000 is a superb natural-clear-flavoured proposition in the market of classical / jazz / unplugged specialized drivers.

At-a-glance Card

PROs	CONs
Phenomenal imaging on a 3D soundstage.	Not recommended for musical genres requiring strong, pulpy & loud presentations e.g. hard rock, EDM etc.
Even more phenomenal masterful treble tuning offering countless and superbly polished details.	Requires at least some amp power, can’t pair with most phones and lowend dongles.
Scales well with source quality, up to a really stunning level.	Uncommon (although not proprietary) cable connector format.
Full bilateral extension.
Super-snappy transients, in the same league of a planar driver.
Recessed shaped 2pin female connector guarantees stability and polarity.
Pairs wonderfully with inherently unplugged genres e.g. classical, jazz and some prog rock
Huge value for the money

Signature analysis

Tonality	A3000 tonality is neutral with a bump in the mids, let’s say a centrally accented W shape. Trebles are amongst the stars of the show yet tonality is not bright. Timbre is clear & clean (which might be mistaken for brightness). Transients are lightning fast all accross the spectrum, same speed league as a planar driver.
Sub-Bass	Fully extended, very fast and totally un-enhanced. Sub bass notes are all there where they belong, yet nothing is pushing to take a millimiter more of space on the scene.
Mid Bass	Un-enhanced, moderately punchy, nicely textured and detailed thanks to razor sharp transients.
Mids	Unrecessed in the low part more forward in the high part, detailed, lean, transparent/uncolored. Highmids in particular are incredibly well managed for how sparkly they are.
Male Vocals	Detailed, lean and quite transparent. They sound natural, might even say too natural, naked, as there’s no concessions to enhancement, which might come out a bit punishing on baritones for example.
Female Vocals	Similarly to males, females are also clean and clear and I can’t call them thin, although they’re certainly not lush, let alone flowered. Unsibilant in site of all that vividness and clarity. Amazing.
Highs	Superbly present while at the same time you never can call them artificial. They come out into an absolute natural sensation, and that’s the section where the difference is more evident with other IEMs which choose (or need) to tame them the section to avoid shoutyness, or surrender to various bright added flavours, ending up in plastic, metallic or other colorations. A3000 trebles sound natural, complete, clean, brilliant. Extension into the high octave is also very smart: it is there – big time – but relative peaks are fully controlled and nothing breaks the magic. A3000 is the single most trebly driver I would not call bright, let alone screechy or shouty.

Technicalities

Soundstage	Very extensive in width and height and just a bit less in depth. This and imaging are the 2 aspects which will scale most with source quality, yet A3000 already offers good stage delivery even on quite entry level amps.
Imaging	It’s from another world, especially if your source is also of good quality – but like soundstage it’s already very good on “common” medium-tier sources. The entire space around the listener is blossoming with instruments and voices, each one presenting a host of details that you might easily happen to never have noticed before.
Details	Yet another masteful achievement: details are so many, so precise and blossoming everywhere, while at the same time not too thin, and not too many, which is one of the typical shortcomings on cheap “highly detailed drivers”, mesmerizing at first but quickly overwhelming with information that make it indeed harder to following the musical story.
Instrument separation	A3000 separation and layering also are great. Pushing amp volume too high might make them fuzzier, especially depending on amp quality.
Driveability	Although impedance is not excessively low, sensitivity indeed is low and this calls for an at least somewhat powerful source. Usual phones are off, so are entry level dongles and such. On the other hand, usual desktop amps will screw the presentation for the opposite excess. Use of an iEMatch or similar attenuator is imperative in those cases. Excessive power apart, A3000 is quite forgiving in terms of source quality: its presentation results in good output even on entry level sources: on (say) an Hiby R3Pro A3000 is nice and ok, while it gets breathtaking on Apogee Groove, and even on Sony NW-A55.

Physicals

Build	The ABS resin material appears fully resistant to normal solicitations. Recessed and notched cable connectors are on one hand a great choice to guarantee solid grip and correct polarity insertion as well, on the other hand most budget-bracket 3d-party 2pin cables won’t fit.
Fit	A 3-contact-point fit between the housing and the concha has been designed by final aiming at offering the best compromise between wearing firmness and light stress accumulation over time. I would say that works as intended. What I find sub-ideal is the nozzle length which is a tad too short and make tip selection picky. In my case the trick is choosing a bigger size for the left ear: that way I do get a firm seal even if the tip stops “just in” the canal, relieving the need to push the housings too much into my left concha.
Comfort	A3000’s particular housings size, their 3-point-fit design, and their external finish all contribute to a great comfort once the right “personal” position is found.
Isolation	Good passive isolation once housings are properly fitted
Cable	A3000’s stock cable “looks” underwhelming at first but I frankly can’t say anything bad about it both mechanically and sound wise. Due to the aforementioned recessed 2pin receptacles issue I could only try just one alternative cable (Nicehck 23AWG High Purity OFC) which is sound wise a worse pair (modestly enhances highmids which is not good on A3000). I’m planning to order a 3rd party high purity copper with the right plugs soon and test that. Regardless, stock one is 100% decent at the very least.

Conclusions

By design (!) final A3000 is supposed to be the opposite of an all rounder, and superbly fine-tuned for its intended application – which, in my experience, is a 100% achieved target.

Even beyond that, very simply put I auditioned no other natural/clear-tuned IEM under €150 which didn’t come with at least one or more of the following inconveniences: driver incoherence, lack of balance, excessive brightness, excessive presence trebles, sibilance. Avoiding all of that at the same time, and doing it at the asking price for A3000 must not be so easy, as it evidently takes a company like final – and for now, to my knowledge, no other – to deliver on that.

Applied to unplugged, acoustic tracks A3000 delivers nothing short of stunning clear sound, imaging and layering, which makes each instrument’s voice in the band pop out with unique authority. I just love how they sound.

Clarity and neutrality being their main cyphers, mid bass and sub bass come accross un-enhanced. A3000’s calibrated precision and emotion, detail and musicality nevertheless are by far the best match I ever auditioned until today applied to cool jazz, under € 150 asking price.

If a punchy, razor-sharp and meaty contrabbasso is a priority when listening to hardbop, A3000 won’t deliver on that. It takes however a pretty penny to have that properly executed, without losing too much on the other counts of course – more precisely I got this on Ikko OH10 for almost twice A3000’s price, or final B3 for more than 3 times that.

Oh before I forget … A3000 like all of the other final IEMs I own and use are a direct purchase. I did not receive those as sample units, I am not a final reviewer, I have no commercial relations with them (other than being a paying customer of course). At the time of this article, they were solely available from final’s direct shop.

P.S. – Just for the record, as any truly affectionated user already knows, spelling final Co., Ltd. lowercase (“final”) is not a typo 🙂
