final A4000 Single High Precision Dynamic Driver IEM Earphones With Detachable Cable

I have never heard another pair of iems so spacious before, I own Hifiman Sundaras and these are about as close as you can get in iem form when it comes to soundstage. Fantastic tuning as well, nice deep bass and incredible clean and crisp mids. Some people may not like the treble however, these are pretty sparkly up top. They aren't sibilant but they are definitely not too far off on occasion. I would say the highs remind me of something like the koss ksc75. For me these are tuned about perfectly for what I like. They feel a little cheap and plasticy, however the comfort is off the charts! I was not a fan of the ear hooks they came with so I replaced with a balanced 4.4 cable from triptowin, although these are easy to drive so they don't need the extra power at all. I highly recommend these and doubt you can find anything this well rounded near this in price, these are the best iems I have ever used by far.

As a total package, these are very much worth the money. However, I've decided to return my pair as they don't meet my needs. I'll explain why after first going through what I like about them.PROS:- Great build. The materials are light, yet feel durable and fit together coherently. The included case is one of the best IEM cases ever made IMO, and the earhooks are a huge improvement over the thinner, less helpful E series hooks (though I didn't find myself using them as the cable sits over the back of my ear well enough without them). I don't typically factor build quality into my opinions unless it's particularly bad or impractical, but all the design choices here come together to make an IEM I that is easy to carry around, that you don't have to worry about treating particularly kindly, and that looks sleek to boot.- PERFECT fit. Obviously, this is highly subjective, but these are possibly THE best fitting IEMs I've worn, and I've worn a lot. The lightness is a big plus here, as the shell doesn't pull down on the nozzle while it's in your ear like many "premium" feeling, metal-shelled IEMs do, nor does the cable apply any weight. I believe the main two reasons these fit so well, though, are the shell shape and short nozzle. Like Sennheiser's IE lineup, these primarily sit against the bottom of your concha, and the eartips don't protrude far enough to contend with the contours of the ear canal. I think people who have issues with the fit of other IEMs will find relief with these!- Above average tuning. While I'll get to my gripes with the sound in a second, it definitely isn't bad. It's pretty balanced and avoids the large pinna gain hump in the upper mids that most people have accepted as part of a “neutral” or “accurate” tuning, and I think this makes for a safer, more relaxed listen for people that are sensitive to upper-mid “bite” or “shout.” The treble is inoffensive yet clear enough. They have ample mid-bass. The mids are smooth and fairly detailed. Unless you’re looking for something that feels more textured for music like metal or that has greater sub-bass impact for bass-heavy genres like EDM, these are good all-rounders for anything you throw at them, which isn’t a quality IEMs earn easily. If you’re coming from an average set of earbuds, these will definitely be an improvement in terms of detail and tonality regardless of what you listen to.- Soundstage! The reason anyone gets these. Their imaging is very circular, placing instruments around your head with plenty of room. I didn’t find the actual size of the “stage” it creates in your head to be particularly wide, largely due to poor dynamics hampering the illusion, but I don’t expect other people will feel the same way. Voices in particular feel stretched out in a pleasant way.CONS:- Dynamics - I think these perform poorly in every sense of this vague audiophile term. The dynamic range is bad in that there isn’t a very good sense of contrast between quiet and loud sounds, which COULD be a positive for me (it can make listening at low volumes easier) if these weren’t also so smeary (again, I’ll get to this in a second). The bass and treble are tuned in a way that eliminates any sense of impact, and while they’re more detailed than the average earbud, the microdetails simply aren’t there. They just sound a little flat.- Bass - to go into more detail, the bass is a little weird. Not overemphasized, but proportionally out of whack. The mid-bass bleeds into the mids not in a way that obscures detail but in a way that makes both sections less satisfying to listen to. The sub-bass is very weak, and when paired with this humpy mid-bass makes for a sensation more like being slapped with a towel than being punched when kick drums hit. In this context, I prefer getting punched.- Smeariness/Smogginess? Not looking to invent new vague audiophile terms, but this feels most appropriate. Just a little dirty and unclear compared to others in the price range. The ends of sounds smear into one another, and the beginnings lack speed or excitement. To me, it’s the audio equivalent of peering at a city skyline through a thin layer of smog. You can make things out, and the obstruction might not be as hard to see through as a thick cloud of fog, but it’s dirtier, pollutes the colors, makes things kind of blurry and less detailed and not so fun to look at. Together, these qualities make for an earphone that lets me hear my music pretty well but never feel like I’m “in” it.Perhaps the best thing about these is that they’re very safe. If someone gifted these to me, or if they were my first pair of good IEMs, or if I didn’t have a bit more flexibility with my budget and had to settle on a *single* sub-$100 IEM to fit all my use cases, I definitely wouldn’t be unhappy with these–they check all the right boxes for the money. They just aren’t what I’m looking for. They don’t deliver the satisfying sub-bass rumble or more controlled mid-bass punch that I like, they’re smeary, they’re not as detailed as some cheaper offerings like Tin Hifi or Moondrop’s products, etc. I’m in a weird spot where they’re easy to recommend and difficult to keep.

Using this with a earstudio es100 MK2, you can really hear change in the ak4375a dac digital filter options.....it's excellent sound reproduction, best part is you can shape the sound how u want it...treble, mids or bassy.....it works.... definitely recommend it anyone,The seller was good, responsive and quick shipping, audioequip was the seller not Amazon,

The Final A4000 has a neutral tonality with the upper end leaning bright. The low end is fast and punchy, slightly recessed. Comfort is on par with similarly priced iems and the included ear hooks were nice but I ended up removing them.The soundstage - it’s good, made much better with foam tips to get the best out of them. The Joshua Valour review isn’t necessarily overhyped but you should try a few different tips to maximize the sound according to your preference. The A4000 excels at instrument separation and has a very enjoyable tonality.Coming from a Tin T4, I prefer the tonality of the A4000. The midrange is more open and it seems to be more clear in general. I will note that the upper frequencies are elevated, not painfully sibilant, but right on the edge of unnatural.The cable does not have microphonic issues but feels cheap nonetheless. I’ve heard they don’t fit all 2 pin cables since there is a notch in the housing.READ ALL THE WAY FOR UPDATE:One issue with my specific pair - the left channel distorts/chatters noticeably around 50-60hz at higher volumes. Does not disturb the listening experience but as a snobby nerd it does bug me every then! May return to get another pair that passed the QC with flying colors. ;)UPDATE: Final swapped my pair for a new, and they sound perfectly balanced L/R.Bottom line - if you are looking for your first IEM or are adding to your Chifi collection, this is a great one.

Final in the UK has been known for their Sonorous range. In 2020, i discovered their earphone range. My first Final Earphone was the impressive E5000' A4000 is equally impressive. Final has been in my top 2 brands for a wired earphones. As most of my music is Hi res.Bluetooth has not evolved to give to deliver true Hi Res. Capable Earphones with DAC's are needed. With or without, the A4000 is brilliant A detail rich sound.Having had opportunity to audition the flagship Final A8000, the sound DNA is present in the A4000. This Paired with a good portable DAC/ Headphone amp, sound is way better than wired earphones double the price. Depending upon source a DAC is only necessary for high res playback. Caution, increasing the sound to an unacceptable level the detail is lost and sibilance (especially on mids and high increases Comfort is great. Noise cancelling is acceptable for a wired earphoned with silicon tips.In summary, a gem of an earphone. Bags of detail. Comfortable, Well priced. Well done Final.N
