final E4000, dynamic driver in aluminium housing with MMCX connectors

final E4000


  • E4000

    Sound quality design based on the latest acoustic engineering and psychological research results. Delivers clear sound quality across all bandwidths and a sense of real, true-to life sound.
    Using the usual method of sound creation whereby certain high frequencies are emphasized, you’re given to feel vivid sound when you first listen, but because of this, other ranges become clouded and hard to hear.
    With E4000, no particular sound ranges have been emphasized, and this, together with our commitment to detailed sound expression, results in realistic sound that sounds as if it were being played right in front of you.

    : S’NEXT final (English)


    final E4000, one of the recent additions to the new E series from the very well known S’NEXT Japanese audio company, and their final brand (or more famous as Final Audio Design). Using a single dynamic driver with metal shells and a very compact design, adding a detachable cable MMCX connection, and priced at $150. With a bit of unique sound presentation, pleasant, engaging and detailed, this is a very solid option to this price range.

    The included accessory pack is rather limited with only the new final set of tips that arrive in 5 different sizes from SS to XL, a unique round carry case with a carabiner (or karabiner) to attach to it and a pair of short earguides. Nothing unusual from the final models or from other Japanese companies, unlike various Chinese manufactures that tend to pack their products with a wide array of eartips selection, cases, cables and whatever more.

    Design & Build Quality

    The E4000 takes a very compact design with the small dynamic driver of just 6.4mm inside. The small cylindrical shaped earpieces are made of aluminum in a smooth matte black color that give them a nice, elegant and discreet look. On the rear part there is the final logo. At the bottom the R and L sides marking, while the inner and outer sides have the ‘final’ and ‘E4000’ writings on them, respectively. And finally, on the frontal part the nozzle has a thin mesh material to act as filter (and might have a damping purpose too).

    e4000 (7).JPG

    The material is very lightweight and with very smooth surface they are very easy to fit for practically any ear size. There’re no vents to be spotted on the housings, and yet there is no driver flex issue on the E4000. The nozzle width is of the standard ~5mm which should match several of the common aftermarket ear tips options. The included ear tips are of good silicone quality; similar to the Sony ‘hybrid’ tips but of a thicker/stiffer material, and do provide a very easy seal. The bore on the included tips is likewise narrow and has its effect on the overall sound presentation. Moreover, bi-flanges, SpinFit, Spiral Dot, and many others can be used to tweak the sound a bit.

    e4000 (9).JPG

    The earpieces are really comfortable and can be used with cable either down or up. The earguides are recommended to get a more secure fit, though the length of the included guides is kind of short to surround the whole ear. Isolation is around average though; the seal is good with any ear tips, just that the E4000 won’t block much of the outer ear with its thin and compact straight design.

    The connection is of the standard MMCX type. Haven’t tried to detach and reattach them as the connection seems solid enough. The cable may look a bit plain but is of good quality, nonetheless. Very soft with practically no noise when moving around. Supposedly it has OFC wire material inside, which cannot be confirmed with the solid black coating. It mainly consists of two separated cables attached together from the plug up to the split. The plug is made of strong aluminum material too and seems very durable. The y-split is not as tough, made simply of a plastic or rubbery material, but it also means no extra weight. The MMCX plug are well covered, though there is no real strain relief around them; not much of an issue as the cable is soft enough and there’s always the possibility to replace the whole cable.

    Sound Impressions

    The E4000 is one of the new additions to the final E series, all currently using a single dynamic driver of 6.4mm diameter. Arguably, this size of driver might be considered as a micro-dynamic driver when used as an only driver for an in-ear option, while it is also used as tweeter on multi-dynamic driver setups. Nevertheless, regardless the driver technical details, the E4000 is not something to be considered as small in sound quality and its presentation.

    While being among the less effective IEM sets I’ve tried in years, extra power is not essential to bring the E4000 to its best performance, but just requires a higher volume step to achieve a proper listening volume. Overall, the E4000 has a slightly warm, yet full and rich presentation that keeps a very enjoyable balance from bass to treble without over boosting a specific region, and still it manages not to miss in any particular part. It is definitely not a signature that should classify as ‘neutral’ or too flat; the E4000 does carry a certain coloration to the sound, however it is presented in such a very natural and musical way.

    The bass is full, well defined and rich. There is a small lift on the mid-bass area that is not too offensive but yet present when called forth. The control is excellent and the speed while not the fastest it fails to be slow. Attack and decay feel very natural and coherent. Layering is surprisingly very good with nice detail and separation. Sub-bass too, is of very good quality, and while not with best extension the depth and rumble are very enjoyable and the E4000 is capable of giving a thunderous yet controlled bass response if the track has it.

    In comparison, the E4000 has much a stronger and defined bass than the Vsonic GR07 and higher control too. The iBasso IT01 is darker and together with the Lear Kaleido are closer to the heavy-bass category than the E4000 could be. On the other hand, Dunu Falcon-C or the new Advanced GT3 while not smaller in quantities, are faster and tighter than the E4000 which has a smoother flow.

    The midrange is a strength of the E4000. It is slightly forward, warm and very rich. Balance from low to upper mids is great, though there is a noticeable emphasis on the upper mid region that gives a higher priority to female singers and upper instruments as well. Brass and strings instruments on this upper region simply shine with the E4000, though they tend to take some more attention from the listener, but the texture is really nice and sound very engaging. Foam tips if used, may take down the emphasis a little if more neutrality is wanted. Male voices also sound detailed and textured, though the E4000 is better with Japanese male singers on J-rock/pop genres (not much of a surprise being a Japan made earphone). There is no noticeable bloat from the upper bass region, just some fullness and warmer tonality that merges into the whole mids.

    Apart from the very specific emphasis on the lower treble, the whole treble is smooth but still carries enough energy and sparkle. The extension is more than competent for a below $200 in-ear set and didn’t show any peak even with brighter tracks. Micro detail is easy to discern without having a very upfront and aggressive treble.

    Stage is not very wide, but the presentation doesn’t sound closed or congested. The E4000 can handle complex music without much effort, but of course, not in the way as more analytical tuned earphones.
    On the other hand, transparency is not where the E4000 stands out, and wouldn’t fill under a very ‘liquid’ description. It is airy, accurate and has very good separation, and it is more about being dynamic and very coherent instead of trying to show strong technical characteristics. Immersive, easy to listen and simply musical in the Final Audio type of tuning.

    With the E4000 we can see quite an affordable earphone from final audio that deserves a high value rating. It offers not only an uncompromising discreet and compact design which is really comfortable and solidly built with the detachable cable option (even though it’s MMCX standard), but most importantly sounds really good. It is a good example that mixes quantity and quality all together, with a strong sense of musicality, good control, accuracy and not good overall detail. The slightly colored sound may not fit everyone tastes but it is a very enjoyable in-ear set.

    Pros - Amazing vocals. Smooth tuning with pleasant highs. Pricing.
    Cons - Sub-bass impact and micro-definition is a little wanting.
    Simple Man’s review – Final E4000 (~150 USD incl. import);
    This is called simple man’s review because they are based on the sound of these earphones directly from my mobile phone (HTC 10), using 320 Kbps mp3 tracks. No expensive gears nor lossless tracks,no EQ, and all that hi-fi stuff.


    Product Specs :
    Driver: 6.4mmΦ dynamic driver
    Impedance: 15 Ohms; Sensitivity: 97dB
    Weight: 18g
    Cable: MMCX connectors, 1.2 m, OFC cable - black

    Build – 4.5/5
    Great build quality, super light. The E4000s employ machined black aluminium housings that are very rigid. The cord is of good thickness, not overly thick, still you feel secure with them. The wires are very flexible and feel nice to touch. Not at all springy, they conform nicely to any position you set them to. The MMCX connectors also colour coded with Red with Black to indicate Right and Left respectively. The theme here is black, with black aluminium housings and black cord. The Y splitter is a small cylindrical hard rubber chunk, and so are the MMCX connector housings at the end of the cable. They are closed back unlike the little brother E2000. They have a nice black neck cinch as well. No worries here., minus 0.5 because the E5000 is much more solid and pretty.

    IMAG2482.jpg IMAG2484_BURST002_COVER_2.jpg

    I forgot to mention about the nozzles. Both E5000 and E4000, although housed in stainless steel and aluminium respectively, have hard black plastic nozzles. Since the nozzles aren’t long and protruding, breaking them while tip-rolling is not a point of concern. Still, it’s worth mentioning that they aren’t all metal. They also have a nice white filter to stop dirt from entering the earphones.

    If you’ve already checked out my E5000 review, you can skip all the bits below and jump straight to Sound. Only point is difference compared to E5000 would be with wearing comfort where the E4000 is more comfortable due to lighter weight.

    IMAG2394.jpg IMAG2395.jpg

    Accessories – 5/5
    Ditto E5000.
    Silicon Carrying case: We get a very premium and stylish silicon carrying case that looks great, feels great, and they don’t occupy a lot of space either. They have an unconventional design. It looks like a hollow black bowl of rubber, on the outside we have the Final logo, on the bottom is the flap to open and secure the case, three protruding tabs help to keep them fastened. It has an interesting locking mechanism as well that avoids a zipper. The case is so small that it can hold just one unit comfortably.
    Karabinger: The case also has this facility to deploy a coupling link, which is part of the accessories, so we can fasten them to our belt loops to carry the earphones around. This is pretty cool and can save a pocket when you are out and about.
    Silicon tips: 5 sizes of tips, with the stems having grooves or stripes which have tight clamping force. The grooves enable flexibility to adapt and angle into the ear canals a bit. These tip stems are also colour coded to indicate L/R, and different sizes.
    Ear hooks: They also provide a super slim set of black ear hooks (E5000 has transparent ones) that are flexible and are extremely comfortable as well.

    So much thought an effort has been put into each component to satisfy the spending customer.

    Isolation & Sound leakage – 3.5/5
    Ditto E5000.
    Isolation is left wanting a little. Not as bad as open/semi open earphones, but you can hear speeding cars even with the music on. Sound leakage is not a point of concern even in quiet environments

    Fit – 5/5
    Fit is easy and comfortable. The lighter housing (compared to E5000) only adds to the comfort and ease of use. Around-the-ear and conventional straight-down wear is compatible.

    Microphonics – 4/5
    Ditto E5000.
    Wearing them around-the-ear eliminates touch noise, more so with the ear hooks. Straight down, it is quite present.

    Before we get to the sound:
    You must know that i don’t listen to trance, EDM, or bassy stuff, no metal stuff, so, take my opinion about the extremes of the sound spectrum, and speed,etc., with a grain of salt, as they are just based on the kind of music I listen to- namely Jazz, blues, some progressive rock from the 70s/80s. However, to give a fair review, i include some of my favourite Daft Punk, Tool, NIN, and some Pop songs among my test tracks.

    From Final’s site regarding the tuning of E4000/5000:
    We’ve carried out the sound design of this product based on the latest acoustic engineering and psychological research results. Using the usual method of sound creation whereby high frequencies are given a sharp peak and certain high frequencies are emphasized, you’re given to feel vivid sound when you first listen, but because of this peak, the anteroposterior ranges are masked and hard to hear. With the E series, making the arc of the frequency response smooth overall ensured that no bands were masked, and we achieved high resolution. Compared to E3000/E2000, a purer, subtler sound is achieved.

    *To heighten the resolution across all ranges, acoustic pressure has been lowered. When you listen, the sound appears laid-back; turning the volume up gradually while assimilating this subtlety affords the user a comfortable listening experience. This product is one whose merits become more apparent the longer you use it.

    And, it is interesting to know that Final considers that E5000 is a direct upgrade to E3000, and E4000 is a direct upgrade to E2000.

    Final suggests to gradually turn up the volume and find the sweet spot where we can say that the highs are lows are in line with one another. This sweet spot for me lies between 30 to 50% volume in HTC 10 depending on the track. This is where they sound sublime. The 4000 is easier to drive than the 5000 and accordingly the sweet spot comes a couple of notches below in the volume bar. The E4000 and 5000 are especially made for you listen in the sweet spot. Any more volume, the earphones will not sound as good, and the E4000s will lose some of it’s magic. Once you find this sweet spot, run a few songs and let your brain accustom to the signature. Coming from bright earphones and monitorersque signature, I needed quite a bit of brain burn-in.

    Tips: I tried different tips, but I settled back to the stock tips. They work just fine.

    Sound –

    The E4000 really sounds smooth and in-offensive, yet detailed and lush. The highs are airy, yet not overly done, like those flashy IEMs in the market today. None of the IEMs in the E series come across as flashy, but the E4000 and 2000 have more airiness to them than the cousins. It strikes the perfect balance. If you don’t like overly lush presentation with supreme warmth, the E4000 is for you.

    Let’s have a deeper look.

    The bass is creamy. The sub-bass lies slightly behind the mid-bass in impact. You will feel the sub-bass, softly. The mid-bass hump is not introduced in the wrong place. This is more tastefully positioned in the lower side of the mid-bass. Therefore, they behave very well and do not interfere with mids like some other IEMs with an abominable hump do. The bass isn’t super tight, like the 5000, and presenting the bass texture is not in the topmost of its priorities. That said, this isn’t a bass shy earphone by any means, only, they are not the main players here. The bass is like the Rook providing solid support to the King’s castle. Which brings us to His Majesty

    If all earphones did mids so perfectly, Final wouldn’t have gone for this. They have nailed it. Mids are transparent and notes are perfectly presented. The aren’t thick, they aren’t thin, go figure. All the instruments have some air around them. The timbre is top-notch.

    Without the Queen the King’s castle will soon crumble. The queen of the mids, vocals, is presented in all her glory here. The presentation of vocals here rival Piano Forte II, which is my gold-standard for vocal presentation. Maybe, they are even better. It’s hard to tell. The vocals just pop slightly above the rest of the instruments in the mids. They are treated like a queen and presented like one. If you listen to any song with vocals with these E4000s, the vocal element of the song will be the one captivating you most. It would sound like all the other elements of the song work together to lift and position the vocals in its sanctum sactorum.

    The treble is smooth and they extend well. The treble is on the same level as the bass on impact and presence. The are airy, and play at a good height in the soundstage. I wouldn’t say they are super detailed, but every instrument is clearly presented to you, in a very smooth manner. The cymbals and hi-hats decay very tastefully, and I might even go so far to say they add a nice splash to the highs. The treble can be likened to the Bishop on the chess board, cutting across like hot knife through butter.

    The soundstage is wide and have very good height, taller than E5000. It also displays good depth of field, but not so much as the 5000 clearly. Instrument positioning is very decent, and each sound owns some air around them to make their position clear.


    Final E4000 (~$150) vs Final E2000 (~$40)
    Let’s first see how much of an upgrade the 4000 is from its little brother the E2000.


    If earphones like humans can grow up, E2000 will grow up to be the E4000. I’m not joking. Switching from 2000 to 4000, I find everything sounds better and more refined. It’s basically the same signature with better clarity, better instrument separation, better definition, deeper and tighter bass. Vocals are also better. If you love the E2000, you must totally save up and buy the E4000.

    Final E5000 (~$300) vs Final E4000 (~$150)
    Let’s see how the E5000 stands alongside the E4000, it’s cousin.


    Mids is the King in E4000, and Bass is King in the E5000. Vocals is the queen in E4000, Subtle Detail is queen in the E5000.

    The E5000 bass hit harder and goes deeper, and is more authoritative. There is this great amount of lushness and warmth that is considerably tamed in the 4000. As a result, switching from E5000 to E4000, the mids appear forwarded. Mids come across as more transparent and vocals are more present in the E4000. In E5000, the mids are lush, warmer, also you can perceive better tightness and micro-definition in the E5000. Instrument separation is better in E5000 as a result. Details are subtler in E5000. Vocals are forwarded and sound mesmerising in the E4000s. They float to the top and tease you plenty. Like I said in the E5000 comparison, If you love mids and vocals, E4000 is the best of the bunch. If you want the best of definition and the deepest sub bass impact, then E5000 will not dissapoint.


    Flare Audio R2A (~$150 – extinct) vs Final E4000 (~$150)
    The Final E series, upon first listening, immediately reminded me of the R2A. They also have a very warm tuning with lush mids and nice vocals. Let’s see how they compare.

    The bass goes deeper in the E4000 and has tighter and better control, and a very slightly bigger impact. Bass is slightly muddy in comparison in the R2As. The treble is more pronounced in the R2A and chimes and hi-hats have a sharper, harsher, quality to them as opposed to the smoothness of the 4000. The amount of warmth is very similar. The E4000 shows more depth than the R2A. Vocals are clearer and better in the 4000 as well. Trumpets and horns sound a little thicker (better?) in the R2A for some reason. Instrument separation is on a level. They are more similar than different, and the differences mentioned are slight in quantity (except treble). R2A can be called the brother that strayed from the E series family and went rogue.

    Final E4000 (~$150) vs Final Audio Design Heaven IV (~$140)
    This is just a reference comparison.

    The difference is BA vs Dynamic. The Final is much brighter in comparison, with forward and brighter highs, greater on-your-face detail presentation. The Heaven IV is in no way harsh, but the 4000 is much smoother is comparison. The bass is better and digs deeper in the 4000 as well. Instrument separation is perceived better in Heaven IV vs the subtler presentation in the 4000. Clarity and definition is on the level, I would say. Maybe a slight edge to the BA driver. E4000 is more organic. Heaven IV comes across as analytical and boring in comparison (can you believe that?)

    Final E4000 (~$150) vs ATH CKR100 (~$400)
    ATH CKR100 was my most favourite IEM before I had the E series in my possession. Now, I don’t know if I like E series better or not. Anyway, this is an interesting comparison with E4000, so let’s get to it.

    The CKR100 is also a lush earphone that has forward mids and good presence in the highs as well. In terms of warmth, they are very close in quantity. Bass quality is stellar as well, with the CKR100 reaching deeper, but the overall bass quantity is higher in E4000. The bass is “correctly” done with the CKR100. Vocals are also great in both, I would be hard pressed to admit a winner here. The highs being more present, displays more clarity and better definition in the CKR100. Every instrument is very clearly portrayed in the CKR100. The smoothness of the 4000 somewhat presents all this in a subtler fashion, but this works in favour towards the E4000 as it adds that little magic (with prolonged listening) that comes with smoother highs. CKR100 is a more rounded earphone that appeals to your brain, whereas the E4000 with its smoothness speaks to your heart directly.

    If you can own only 4 IEMs in total, I would say you must have the following:
    1. E5000 (for warm, lush, subtle, creamy goodness with an extra helping of bass)
    2. E4000 (smooth and subtle highs with forward mids, and goddess-like vocals)
    3. ATH CKR100 (best overall signature, “well-rounded” is what comes to mind)
    4. Etymotic ER4XR (Analytical monitor– just to know what is hidden out there)

    Overall Sound rating of Final E4000:
    Vocals 5/5
    Soundstage 4/5
    Instrument Separation 5/5
    Details 4/5
    Timber 5/5

    Conclusion –
    The E4000s deliver one of the best mids created in IEMs where the vocals “speak” more than they sing. The smoothened highs and warm lows only add to the magic of the mids. Presents a very organic sound nailing the timbre right. Nuanced delivery of details is the name of the game. For the price, it’s really a no brainer if your priority is to enjoy music in a laid-back manner. Five stars because priced right.
