Market map right now:

Fiio with an in-house planar 100$
Aful 2DD, 4Ba, Planar 300$
Tangzu Zhu Bajie DD, 4BA, Bone conduction + Est 600$

All of them are effortlessly singing which tells about the quality of the implementation.

Seems like Final decided to ignore construction beyond single DD and maybe next year we'll see a A7000 for 500$ aka market segmentation.
No tuning nor work on the chamber, nor marketing or name dropping can align with internal R&D and engineering.
Serious players are moving fast for our benefits.
Final lost smth with this release...
Not a single Fiio IEM, ever, has stood the test of time.

Not a single AFUL IEM has really lasted beyond the initial hype.

TangZu isn't even competitive with the likes of KiwiEars, and they likely won't ever be with the way they just rehash existing multi-driver designs with no proprietary tech.

A single DD is all you need for full audible frequency reproduction. Sennheiser IE 900 is one of the most "well extended" IEMs in the market. Single-DD. The driver dome is not even metal. It does all that thanks to proprietary housing design and the quadruple helmholtz resonators. THD is <0.1% in most regions. EQ your heart away if you want, though I don't need that.

All that driver performance needs R&D and millions spent in custom molding, specific machinaries to create a reusable driver platform. The entire IE series, for example, uses similar driver structure, with the IE 900 having no damping material in front at all to maximize driver performance and perceived resolution (tell the brands you mentioned to create an IEM without dampers in the sound path that doesn't sound shrill. They can't.)

Final's A and E-series drivers are also on a similarly scalable platform. E5000 have four different types of damping schemes around the isolated driver chamber. Till date, no other IEM has implemented such and overkill structure for the sake of "driver control" alone (that is the reason why E5000 are so hard to drive).

Then comes longevity. Final E5000, for example, has gone strong for me like 6 years now. Used it every day for the first 3 years. The Fiio stuff I bought in between have already broken apart or sounds wrong. TangZu and AFUL are not even that old as brands and given their QC standards and lack of customer support, I ain't holding my breath.

This notion about multi-drivers being superior is too generalistic. Most, as in, 99% of multi-driver IEMs sound incoherent. The ones that sound coherent cost a lot (Symphonium Crimson, VE EXT, Trailli to name a few). Well-implemented single-DDs sound coherent by design, no drama with phase mismatch or the typical high odd order distortion of BA drivers, or EST drivers having mismatched driver SPL/speed. Worst offender is the newfound BC driver that just sounds wrong when paired with the other "air-conducted" driver types.

Now, some may prefer that kind of presentation and it's all fine. But claiming those are superior vs a single-DD based on nothing but spec sheet is quite wrong and misleading.

Also, nobody is moving fast for "our benefit". They keep releasing new stuff just to maximize hype and boost sales. That is to the detriment of the buyer, last I checked.

Final rep claimed a6k has the same berry driver as a8k (and, with better tonal balance?!), yet a6k has the same driver as a3k? Please let me know what I'm missing here...
I think something got lost in the translation there. A6000 does not use the pure Be foil driver of the A8000, that much is apparent. However, it has the same driver mounting method that was first seen on A8000, and the acoustic chamber seems to have similarities, which should replicate certain characteristics of the A8000 (tactility of notes, for one).

I also think they reduced the 6kHz peak on the A8000 that is the reason why many find them intense. At the same time, that 6kHz peak is the reason why A8000 sound so incisive and "raw", so it's not the real thing, but something mimicking that.

AFUL are not even that old as brands and given their QC standards and lack of customer support, I ain't holding my breath.

Here are some screenshots from your own Headphonesty reviews where you state the
- OUTSTANDING quality of AFUL product.
- Qualify Final as poor.

Then you came here to write about AFul QC problems and promote final build quality?

It's seems those multi-drivers are more coherent and less influenced by daily parameters.

Don't mind if I block you as I see an influencer not a reviewer?

Build quality is good. Long term usability is a different topic. It's impossible to ascertain in a short term review.

The HTML tags on the final ZE8000 review are not working properly, actual score is different. It has very good build quality and is rated as such in the actual review, if you bothered to scroll down that is.

If you can't take a different opinion, social media in general is probably not for you.

AFUL is pretty awesome mate. Don’t need to trash it as a counter for the other argument.

I still love my E5000 and A4000. Fingercrossed for a good A6000. My finger keeps hovering over the old single BA IEMs from final on discount at a local store. Maybe I’ll wait to try the new single BA series first.

They just might be, the ones I have tried so far have been in the "good but not remarkable" category. Didn't try the flagship yet, might be a standout, should get a sample to try out soon.

I think the new BA series will be a better bet (those are double-BA drivers from what I've seen in the product pages, each being in its own acoustic sub-structure).

I have owned a few of the older BA-only models including Heaven VI and the mythical FI-BA-SS (first ever vented BA in an IEM). Even the flagship FI-BA-SS will not be competitive in the modern landscape (it was $1000+ back in 2010, now I think most $200 IEMs will beat it). So getting the newer ones seems to be the way to go as BA drivers have come a long, long way (Knowles' dual diaphragm BAs are fantastic if implemented well).

So getting the newer ones seems to be the way to go as BA drivers have come a long, long way (Knowles' dual diaphragm BAs are fantastic if implemented well).

I agree, at least to an extent: I have Heaven IV, V and VI, and I heard (your!) FI-BA-SS and yes they are "obsolete" in commercial terms: there are, indeed, (non-chifi) alternatives at lower prices now. With that said, Heaven VI are really close to F7200 on my score, and F7200 are still nowadays the most outstanding drivers of my collection for vocals / songwriters and such. Too vertical if you wish, so rarely pulled out, but still...

On a higher / wider level, let's be frank: as end-users we owe chifi low-price. low-quality, highly-aggressive manufacturers at least for one thing: having contributed putting commercial pressure on higher-tech, higher-quality old-world manufacturers, which already since some time now are delivering very significant products at much lower prices compared to 10-20 years ago. This didn't happen on the audio industry only of course.

Be as it may, if I were to consider buying a pair of IEMs today I would not entrust a chifi manufacturer for an expensive product as I would fear about their long term performance, and I would hardly look at one either for a low cost product, as there is plenty of non-chifi alternatives even below 50€ offering me higher confidence.

Low price wins vs low demands / expectations. ...Only!
For all the rest, quality at an affordable price is the way.

My comment for A8000.
  • It is bright IEM, no one can deny that.
  • The most problem is its typical Vshape, which lack engagement and excitement in mainstream.
  • You need to change eartips, which absord some micro energy and nuance.
  • You need to change cable, which remove the effects of SPC cable, which make the problem of Vshape, brightness worse.
  • You need hight quality source, which counter the hight peak in treble region.

I wanted to like the S4000 and the S5000 (particularly the former as it’s beautiful) but even coming from someone who really enjoys the E5000 I was really disappointed. Like imagine all the bad things about the E5000 paired with the apple dongle but with nothing to make up for it. They sound low res, muffled and lifeless; and gets even worse the more you pay. I think the tips have something to do with it as they look similar to the TC50 which are really dark but they’re both still a pass for me.

The A6000 on the other hand is nice.
