final E4000

General Information


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.

Latest reviews

SOUND: 9/10
DESIGN: 9.5/10
VALUE: 9/10



The FINAL AUDIO DESIGN E4000 goal is to achieve a sound that feel natural and musical without ehancing any particular frenquencies. It use last psycho-acoustic research to understand how frequencies are interpret by average human brain and ears, and so be able to tune it so there no important physiological frequencies range that feel masked, unbalanced or artificial sounding.

This is extremely complex tuning work as nobody have exact same hearing, as well, must of audio enthousiast are use to specific soundsignature that tend to make them more sensible to certain frequencies. And to make the challenge even more courageaous, Final Audio use a tiny 6.4mm dynamic driver.

So, for once, here, I believe in brain burn in with the E4000, or more likely, unbalanced acoustic brain memory unlearning.

Even without this ‘’brain burnin’’, as I begin to be annoy with overlly coloured iem, and tend to listen to more balanced one, the very first time I put the E4000 in my ears please me, but it was just a begining of a way more fascination listening experience, as if everyday I find a new pages to read in a book I love.

Final Audio Design company is very serious about sound acoustic, but this doesn’t mean it will sound less musical or too cold, the engineer are sure interest about musical rendering as much as sound technicalities, and there approach is based on a wide knowledge that make there earphones appart from the rest, its supreme respect for music and I find there tuning quest extremely inpsiring.

UNBOXING experience is elegant yet minimalist. No big box for nothing, here, we have all what is needed in an humble presentation. A unique carrying case made of silicone, wich I personally find fantastic, silicone eartips of great quality (for real), nice earhooks that aren’t to big, and….a karabiner, for when you do hardcore montain climbing and need to hook your carrying case with the E4000 securly hidden in it, because yeah, it’s just not possible to depart from these marvelous earphones.

P2180697.JPG blog_origami_directions.jpg

As well, I have a weakness for little precious details like how both iem and audio jack are all carefully wrapped in little triangle plastic paper. I have to take a pic, enjoy this masterufll origami work, I think it represent 3 audiophile swans whistling some Tchaikovsky melody.

P2280843.JPG P2280839.JPG P2280831.JPG

Construction is well crafted, and beauty here reside in little details. Must of all, its the very durable look of such a tiny iem that sure will please consumer because I don’t think its really possible to break the housing, only mmcx connection could theorically be broken by hardcore mistreatment but again it look extremely solid as we can conclude with the tigh connection it give. Housing is made of high quality aluminum that promise unwanted vibration to be avoid because of its tickness and have an back acoustic chamber. As well, even if hardly visible on pics or with our own eyes, there a back venting trap at the right of mmcx connection.

Design is just incredibly slim and comfortable, and will fit any type of ears. I find isolation great, and sound leakage minimal even if yes, if you listen very loud, it will leak, but not to the point of being problematic apart if you want them to be completly silent. MMCX connection are very tigh, wich is a big plus as with too loose mmcx connecction it can disconnect when you accidentaly pull the cable : one thing sure, this will never happen with the E4000. Cable do minimal microphonic, but I suggest to wear over ear if you plan to move a lot, like running or doing zumba.



Overall sound impressions and flavor discovering :

The E4000 was the first Final Audio earphones I put in my ears when I receive them with the E2000 and 3000. I try them first being the pricier of the batch (yeah, typical!) and with great expactation wich was due to the fact I was just tired must my IEM was sounding either too bright or too bassy, and especially, I begin devloping very high intolerance to gluten hissy vocal with the time, wich is something chi-fi audio engineer are must likely enamoured of.

So, i put the E4000 in my ultra-hardcore-critical-mode-ears and press play on my Xduoo X20 and : Amaze I was. It just sound like music should be : Pleasant, clear and cuddling.

The E4000 was tender to me! They give me love without violence! And generous musical passion! I was listening to a jazz album from Jakob Bro quartet, the bass player have great body and natural non intrusive texture, the timbre was right and full, snare drums was fabulous, with a thick impact that lack in pushed treble iem, and its percussion was tigh and around my head, the guitar wasn’t full of artificial decay, it was controled and the note have consistance, and the saxophone, wich was recorder above the other musicians, was full, wide and transparent, all instrument was layered precisely with excellent details in whole sound spectrum...perhaps some would have like to hear the drummer scratch himself between two rythm section in the background , but I don’t care about this type of micro details really and the drummer too don’t care surely.

E4000 is masterfully tuned, in a unique way that permit you to hear everything on same level from 20hz to about 14khz, after this there a slow drop, and perhaps bumps in the drops but no hard peaks, all is smooth, liquid, organic and utterly enjoyable for long listen.


SOUNDSIGNATURE is towards neutral, with gently smoothed treble but particularly well rendered transparency and timbre, bass is slightly pushed fowards for extra body and punch and mids shine in the middle of a masterfully balanced presentation leaning to a chiaroscuro type of darkness were light and shadow mix togheter for addictive musicality. Hum, yeah, its a poetical soundsignature.

SOUNDSTAGE have a stereo like widness, it have a natural transparency in layers that make it feel deep tough it do not have lot of sparkle decay in they air.

AMPING is suggested, but not a monster amp, just a powerfull DAP or portable AMP will do. Due to its low sensitivity of 97db, even if it got as well a low 15ohm impendance that should manage for easy driving, the E4000 open up when we can achieve proper amping. Strangely, having try multiple single drivers IEM, I feel smaller is the drivers, harder it is to drive it. Can’t explain it, but this is what I experience. So to me, sound improve alot with a portable amp amd make the soundstage feel way more airier and imaging more spot on.

BASS is far from lacking, in fact, bass shy people will consider the E4000 quite generous in this department, as it is quite agile and thick without being particularly fowards. But no sub rumble full of air, here it’s good sub body with extra timbre, its tigh and well layered from mid bass, wich is impressively visible with fast electronic like Aphex Twin, I would never have guessed it can deal with electronic so well, but for punchy electro its excellent, for boomy rap or drum and bass it will not be enough coloured and too smooth perhaps. The extension is very linear as we can hear with bass player, it have more body and tone emphasis than texture, even if it do not lack any to my ears, in fact, too much texture in bass can make it too opaque, here we have a neutral approach where timbre and tone is more important than underlined texture. So, as you can guess, you will have no bass bleed into mids and vocal with the E4000, mids litterally sit on the bass.

MID BASS is a little less emphased than lower end, wich give it slight warmness and round it more softly, but it still have good slam, even in bass heavy track like FOG from Nosaj Thing where the kick is full bodied and sub bass synth stay in background. Again, level of separation, without being clinical, have a good transparency to it.

MIDS are uniquely presented and my guilty pleasure with the E4000, because as said before, I can’t stand hissing and the soft presentation just solve all issue about lower ‘’shhh’’ or upper ‘’sssss-ibilance’’, and that...without making the mids sound recessed or lifeless, is just phenomenal. It still have a wide bodied presentation and excellent clarity, as well as fowarded presence, the thing is that you will hear all other instrumental in mids region while your favorite artist sign and it will never sound mushy. Yep, wer’e still talking about a 6.4mm dynamic driver. Hum. Piano note have good weight and accuracy, whatever the register, the tone sound right, as the control do not decay too much it give, unlike numerous iem that tend to mix vocal with piano ackwardly, a perfectly natural layering that impress by its accuracy.

HIGHS are more hearable in 6khz to 10khz range than with lot of other iem I try, but this only if they are present in mastering, treble will not push them fowards for us by creating false sens of dynamic, it will stay linear so no peaks will stole presence of other frequencies. I find this very revealing for proper instrument separation playing in same range as it give more overall clarity, percussion suddenly can became more complex, especially if acoustic. Piano, violin and cello sound more appropriate with the E2000, as well, track like ‘’Reflection’’ from Vassilis Tsabropoulos trio ‘’Melos’’ never sound more realist and balanced, as with other iem, one of the 3 musicians playing always have second seat, here piano and cello have great resolution and presence and the percussion is on same level, not too fowards and shimmy as I always hear before, its tigh, accurate, agile and well separated from rest of instrument, as if the trio was playing in front of me in the perfect acoustic room that do not have ampplifier or too much echo.


BASS : Warm, punchy with good timbre, body and separation.

MIDS : Clear, intimate, full sounding and natural.

HIGHS : Soft, good timbre, good attack, precise and well layered.



VS Brainwavz B200 (100$) :

P2280833.JPG P2280835.JPG

B200 have a wider around your head soundstage, with more decay, wich is a plus for not too complex tracks while a drawback for more complex due to extra echo and decay that can veil certain frequencies range especially in bass region and lower and middle mids.

E4000 in other hand feel overall better balanced and more agile in layering.

Bass of E4000 is more bodied, especially in mid bass where the punch have more weight than the dryer hitting of B200, sub bass of B200 have some roll off begining around 100hz that make it feel tinner than the E4000 even it have a bump to compensate lack of weight. This make E4000 more natural and realist in lower end without the need of any treble push, its lively and make it for better rounded up presence. B200 feel mid centric compared to more neutral E4000, and have upper mids fowardness give extra presence to violin or vocal, but not to piano note that lack weight, another time, the mids of E4000 are more realist and have better attack and body in a tigher more intimate presentation, between 2-8khz we can easily separate each instrument that play in this range, while it will be more messy and veiled with B200 mixing.

Highs have more emphasis with the B200, but do not give more details, tough you will have more sparkle and decay and better feel of air with certain music style like solo harpsichord, classical guitar or folk signer. Talking about harpsichord, even if the strings plucking sound less full in attack timbre, but the decay will give extra liveness to the instrument wich is quite delicious in fact even if I would have like better weight in attack. As well, it most be noted that B200 can sometime create little distortion when too much different instrument are mix togheter, like bass, electric guitar, violin and voice….this will never happen with E4000 whatever you trow at it.

All in all, the E4000 is more neutral and agile with less emphasis on mids and vocal, while the E200 is more airy and less bassy and is less a great all arounder than the masterfully tuned E4000.

VS Brainwavz B400 (200$):

P2260783.JPG P2260781.JPG

Braiwavz B400 cost 50$ more than E4000 and have a 4BA’S configuration compared to single 6.4mm drivers of E4000.

Soundsignature are somewhat in same family but tuned differently, it tend towards neutral and balanced with slight bump in mid bass and mids, but the B400 have some bump in sub bass and treble too wich make them overall a hint brighter and sharper.

Soundstage is more holographic with the B400 while the E4000 feel more frontal and little wider with more transparent layer compared to a more hall like withe extra echo of B400.

Amping isn’t needed for B400 as they are more easy to drive even at 32ohm, E4000 benifit from powefull dap or extra amping due to low sound pressure.

BASS of B400 have more sub presence than the E4000 and slightly less mid bass punch and resolution, here E4000 show how even if smooth sounding he can have realistic timbre that give subtle extra body to kick and help a clearer separation with low bass. Sub bass of B400 is thicker and weightier wich will benifit for electronic music while the E4000 bass will benefit rock and jazz.

MIDS are more fowarded with the B400 and have more texture especially in upper mid range, wich give more grip to violin and clearer separation in not too complex music that do not have too much sub bass and highs emphasis. Overall mids timbre of E4000 feel more natural and transparent, but more in center stage too, wich can feel recessed for some.
HIGHS are more sparkly and have more decay with B400, being more fowards and sharp as well, there no treble roll off with these compared to E4000 tamed upper treble wich give more balance and neutrality to overall sound to the cost of softing the dynamic energy. B400 can sound sometime too sharp as well as unbalanced with for example complex jazz were the percussion can feel too fowards, but I think it will be a plus for some listener searching for extra sparkle and details.

All in all, finally, we have two very different sounding iem here, one being more linear and smooth with a natural timbre (E4000) and the other being more sub bassy and energic with extra treble sparkle and around your head airy soundstage.

VS NiceHCK M6 (130$) :

P2280832.JPG P2280848.JPG

M6 is a dual dynamic drivers with 4BA’S drives, it have a W shape soundsignature with warm pumped up bass, fowards mids and extra highs emphasis.

Soundstage is bigger and more 3D layered than the E4000 but less well resolved as some bass veil lower mid range giving it extra warmness. The E4000 is better balanced and sound more realist and agile but less thick and bodied. Soundstage is deeper due to better resolution.

Bass of E4000 have more emphasis on mid bass and feel less congested with the sub bass, where the M6 have more of a whole sub plus kick impact and weight, M6 feel slower and less agile too and as said bass echo mix with mids a little.

MIDS of M6 are more fowards and textured but more prompt to sibilance and feel less natural than the softer E4000, wich is more centered, have better transparency and timbre. They aren’t recessed at all, but are more on same level of rest of instrumental. I find the mids of E4000 extremely more enjoyable than the M6.

HIGHS of M6 are more present, giving more sparkle and clarity in upper region, but treble can feel sometime metallic in this region compared to the lively highs of E4000 wich sound more realist. I feel lower treble is clearer with E4000 too, where the M6 have some selective peaks, especially in upper treble to extrac microdetails.

All in all, the E4000 sound more mature and well tuned, with a smoother but clearer approach while M6 is more energic and fun sounding for electronic.

Both earphones have excellent construction, and even if very big compared to E4000, M6 is very comfortable.



The Final Audio Design E4000 is a masterfully tuned iem with an elegantly balanced soundsignature that reflect frequencies laws knowledge of talented audio engineer and tend to make us, the audiophile with curious ears, more aware of inner miracle of whole transparent audio spectrum. For some, this sound approach can look new age, in the sens very passive listener that like to be beaten up by fowarded low or highs will miss the wow effect that us, the contemplative music lover, will be delighted by.

E4000 deliver a precise, clear sound where every instruments have natural unintrusive presence and as if we were in the perfect acoustic room without too much echo, the music sound always enjoyable and never agressive.

If you search for the perfect soft sound iem that neither lack energy or timbre, I think only the Final Audio E4000 can offer you this type of dense sirupy musical experience.

A classic that will pass test of time.

PS: You can find more reviews of IEM and audio gear here on my website:
Pros: natural tonality, excellent midrange timbre, bass decay, solid build, soft cable, enjoyable smooth & warm tuning
Cons: fit not the most secure, too laid-back in treble for some, trades technicalities for organic sound
The E4000 is a single dynamic driver IEM from final audio design, currently selling for $149 via In a world of multi-driver IEMs being available at continuously plummeting prices, it seems a bit counterproductive to purchase a single-driver IEM at this price point. However, the E4000 has been touted by many to be a solid value — curiosity got the best of me, and here are my impressions.


The E4000 comes with basic accessories. Though not extravagant or elegant in presentation, they are completely adequate and cover the necessities of an IEM in this price range. In the box, you will find:
  • IEMs + cable
  • Carrying case
  • Tips
  • Carabiner
  • Shirt clip
  • Ear hooks

The carrying case is certainly unique, I’ve not seen anything like it except from final audio design. It’s made completely of silicone, and snuggles the IEMs gently when the silicone cover is pressed over the flexible bottom. The carabiner is branded with the final audio logo (unfortunately no photos, as I purchased this set from a friend who couldn’t find the carabiner).


The E4000’s detachable MMCX cable doesn’t look too premium. It looks fairly old-fashioned in fact, lacking the typical braided designs that most detachable cables opt for nowadays. However, it’s very supple and soft, which already places it quite highly above many other cables. It doesn’t maintain much memory and has virtually no springiness, which is generally a plus in my books. Visually, it doesn’t bring much to the table; functionally, it is among one of the better cables I’ve used by far.


The E4000’s design seems to fall in line with the rest of final audio design‘s E-series IEMs, with a minimalist barrel-shaped housing. However, unlike the previous E2000/3000 IEMs, the E4000 thankfully comes with detachable MMCX connectors for cable swapping and peace of mind.

Visually, the E4000’s elongated aluminum body is coated in a jet-black finish, with the slick and stylish final logo imprinted opposing the E4000 model no. in a crisp white. There’s a milled groove near the posterior end of the IEM, wrapping around the entire circumference of the housing. The cylindrical rear has chamfered edges polished in silver, bringing flashy accents to the otherwise simplistic design and encapsulating the final ‘honeycomb’ logo.


The E4000’s fit is mostly comfortable. I don’t have any issues with discomfort, but the elongated barrel design seems to feel considerably less secure in my ears when compared to something like the CA Andromeda. It feels as if the IEMs are being held in my ear almost solely by the tips — as a result, I almost always wear the E4000 with the cable over my ear.


The E4000’s signature can be described as a very coherent, thick & warm sound with moderately boosted bass quantities, paired with warm vocal tones that could be described as ‘lush’, yet maintaining adequate clarity. Treble rolls off noticeably, resulting in a relaxed sound with minimal air. Don’t get the wrong idea though — the bass and midrange are so pleasant that I sometimes forget I even wanted treble sparkle / extension.

The E4000 is satisfyingly bassy. It reaches down low enough without any substantial rolloff until the very lowest registers, where it begins to lose authority. Otherwise, the subbass is presented with a solid amount of rumble and texture. Midbass is full, boosted moderately with a mostly natural decay, straying on the slightly slower side of things. Texturing in the bass is adequate, certainly more impressive than most IEMs in this price range. It’s a very fun and visceral bass presentation overall; in terms of quantity the E4000 could potentially satisfy bassheads, but it tends to straddle the line between normal and basshead quantities.

The E4000’s midrange is also fairly pleasing to listen to with a warm, full, natural tonality. Midbass transitions gently into the upper frequencies, giving the lower midrange a full and thick presentation with plenty of body. As much as I’d like to be logical and assume bass bleed is there, I can’t seem to hear much muddling between bass notes and vocal: this is good. Unexpected, but good — it sounds more like an intentional boost to the throatiness of lower vocal frequencies. Upper midrange is lifted to maintain sensible clarity, giving vocals a slight boost that doesn’t come off as harsh or overdone (no veil here). Texturing in the upper midrange is ample, however it does sound slightly smoothed over. As a result, the E4000’s midrange takes a hit to technicalities but presents itself with a syrupy, ‘sweet’ sound that I find enjoyable and relaxing to listen to.

As expected, with such evident quality poured into the E4000's bass and midrange, the treble turns out to be the most divisive aspect of the sound. Lower treble carries a decent amount of energy, preventing the E4000 from sounding overly mushy or dark. Detail and resolution is also there, though not in the forefront of its tuning -- it's definitely not a priority. The mid-treble and upper-treble begins to roll off noticeably from this point, resulting in a specific sound that is pleasing to the ears, but slightly lacking in air and extension. To an audiophile who wants to hear it all, pick out tiny details and sparkles with ease, this is likely a dealbreaker (note the detail is there -- just not presented with priority). However, this may be one of the E4000's strengths for those who are sensitive to high frequencies, or those who have multiple IEMs and want one with this specific presentation.

Not so much concrete info but rather some minor thoughts I had while listening to the E4000. As some may know, I’m a huge fan of the Campfire Andromeda. Its treble presentation is like no other — when I was first looking for a warm and relaxed IEM, the Andromeda showed me the light and I was finally able to appreciate a more forward treble presentation.

In the first 30 minutes of listening, the E4000 enamoured me with its warmth and ease of listening. The dynamic driver’s natural yet visceral decay left me aching and wanting more when I switched back to the Andromeda; the midrange felt warmer and more inviting. If the Andromeda had turned me into a treblehead, the E4000 was somehow pulling me back to the darkside (or warmside). Sometimes sacrificing sheer technicality, detail and resolution feels worth it in exchange for a guilty-pleasure tuning.


The E4000 certainly has a flavorful, coloured sound. It’s warm, it’s pleasant, and it’s enveloping. It sounds natural and full, though lacking in upper frequency extension. Texturing, detail, and general technicality aren’t its strong suits, but the sound signature can be intoxicating. Thankfully, the tuning of the bass and midrange coloration steal the spotlight from its otherwise obvious treble shortcomings. In terms of design, it sticks to its final audio design roots and sports mostly minimalistic cues that many may find attractive. I have no qualms with the materials used in the housing, and the stock cable is practical and comfortable. At $149, I find the E4000 to be an excellent buy for those who are looking for a natural and organic tone. However, detail-heads and treble-heads, stay away.

This review was first posted on my small Wordpress blog here. Thanks for reading.

Pros: Versatile, natural and exciting signature that is very coherently balanced, small form factor with a comfortable fit, very good build quality, detachable cables, excellent value
Cons: Sound leakage restricts their use in public places

Final (previously known as Final Audio Design) is a Japanese company that produces quite distinctive headphones and IEMs. They have certainly been able to capture my attention, not in the least with their Piano Forte series that have a completely unique earbud/IEM/horn speaker-type of design that has fascinated me ever since I first laid my eyes on them. As a classical music lover the Piano Forte present a compelling proposition and this is perhaps the type of response Final is going for. Final aim at (as they explain it on their website) creating products that elicit the same sort of affinity people have with hand-wound watches, something classical and enduring. Indeed, their specialty Lab series earphones are exquisite pieces of audiophile art I never tire drooling over. But it is not just at the high end of the spectrum where Final creates unique products, their Heaven series of single BA driver IEMs have always listed high on my wish list because I keep reading such positive comments about them. Most recently though a lot of those positive comments have been about another Final series, the E series of small form factor, single dynamic driver IEMs.


The E series launched with the entry level E2000 and E3000, and this was when I finally got my first pair of Final IEMs. Well, not really "my" first Final IEMs because I ended up buying them for my wife when her Trinity Vyrus started falling apart. Since I wanted to hear why people were so excited about the new E series, I leapt at the opportunity to arrange a demo for myself... "Look hunny, I bought you a present!" The ones I bought were the E2000, which was because I gave my wife the choice between the two based on their signature, to which she responded... "The black ones." Granted, I tried them out for training and actually ended up buying a pair for myself as well because I also, kinda preferred the black colour. Although formally I will of course always be adamant I did it because I appreciated the energetic elegance of the v-shaped E2000 better for training. It sounds more like I actually put some thought into it. I didn't, I just wanted to test the form factor because by that time I had already set my sights on the E5000. So when I was asked if I wanted to do a double review of the E4000 and E5000, I said yes without even thinking about it. I had been using the E2000 for a few weeks and they were perfect for training and on-the-go use, and while I did not really worry about sound quality, I kept having to remind myself that I was not listening to much more expensive IEMs. The E2000 just had such a pleasant sound with a stage quite surprisingly wide for the price. So naturally I was curious how much of a step up the E4000 and E5000 would be. Let's find out!


Build quality and fit
The E4000 are really nice small form factor IEMs that have an excellent build quality. Made from aluminium they feel solidly built and yet have the advantage of being very light, even compared to the stainless steel E5000. The cable has MMCX connectors and is a very nice, supple cable that is quite good in terms of microphonics even when worn with the cable down. It is a cheaper cable than the one on the E5000, but I personally prefer the way this one is built. Where I did not really like to use the E5000 for training, the E4000 worked really well with the cable over the ears and even straight down. Combined with the light weight and the secure fit (thanks to the great Final E tips that are included) I was able to use the E4000 for everything without a worry.

One point to be aware of is that the E4000 (and E5000) have a vented design that is almost like it is semi-open. I find the isolation to be decent considering, noise certainly leaks in, but I have still used them quite effectively to reduce some of the environmental noise. However, noise leaks out a lot more and this might make them less ideal for commuting if you like to turn up the volume. It will most likely be heard by people standing close (or sitting close, if you happen to commute in places where people are not being packed in like sardines, but I live in London). Surprisingly this was worse in the case of the E4000 and E5000 than in the E2000, which has what looks like a vented mesh at the back while the newer models look more closed, they clearly are not.


All listening was done with my AK70 from the SE out. Both the E4000 and E5000 seem like very power-hungry IEMs and a good source will make a big difference in how well they sound. When driven by a less powerful source they will sound a little thin and less impressive, but both IEMs come alive when given more power, especially the E5000.

The E4000 have a somewhat U-shaped signature that is tilted a little more towards the treble to give a somewhat brighter, more sparkly, tone in comparison to the E5000, which have a little more emphasis towards the sub-bass. Interestingly I find that the E4000 have a slightly more natural tonality compared to the E5000. Both have quite a nice and natural tone in general, but the E4000 have a slightly looser mid-bass that gives midrange instruments such as woodwinds a little more natural sound. Other instruments such as the cello too, feel just a little more naturally resonant. The E4000 have fun and energetic signature that is a little less impactful than the E5000, but has a little more sparkle. It is still an unapologetically fun signature with plenty of impact. Feed them classical music and it sounds "nice"... Feed them Walk the Moon's 'Headphones' and suddenly the E4000 come alive and it all starts to make a lot more sense. As the lyrics state "you can learn a lot from a good pair of headphones" and in this case it is that a toe tapping and booty shaking sound does not have to cost a kidney.

Much like the E5000 the E4000 have a very wide and tall stage, lacking some depth, but not needing it either. Separation is excellent, as is clarity, although resolution is much less impressive. These are IEMs that offer a lot of fun for little money and the resolution is not really something that is missed because the signature is wonderfully balanced for its purpose and perfectly coherent. Vocals are a little further back and felt they lacked density when compared to the E5000, which I also felt were not the strongest vocals, but the clarity in both cases ensured that vocals still came through cleanly.

As said, the bass is a naturally resonant bass with a very enjoyable impact to it. It does not reach deep, but does give a fullness that works well with a track like Massive Attack's 'Angel', where the bass is warm and thick. It does lack a little bit in sub-bass depth, especially compared to the E5000, but considering the price it is still good. Better than good, and crucial to the fun and exciting sound, is the impact of the bass within the signature as a whole. This is energetic and really sets the pace well, which is why the E4000 offer such great toe-tapping signature, well complimented by the sparkly treble.

The bass is a little loose, which provides warmth for the mid-range and helps instruments such as the cello sound more naturally resonant. While listening to Bach's cello concertos I was really enjoying this. It is not the most detailed and I did not get the texture of the strings all that well, but that is probably mainly because I am so used to much more expensive IEMs. Again, at this price point I find it very hard to fault the E4000.

As indicated in the bass section, the mids have a little bit of added warmth to them that I personally consider to be very natural sounding. In my opinion (that not everyone might agree with) I feel this helps instruments such as woodwinds to sound fuller and more realistic. They become more easily discernable within the presentation of classical symphonies, further helped by the E4000's excellent separation. This is also part of the reason why I feel the E4000 work well for acoustic music, better in fact than the E5000 in terms of relative strengths.

Vocals are very good. They are not the strongest vocals and occasionally can sound a little on the thin side for my taste, but there again that might have to do with the IEMs I am used to listening to on a daily basis. Vocals are certainly very clear and never get overwhelmed by accompanying instruments. I think that for anyone who is on a budget and a vocal music lover, the E4000 are definitely worth a demo. Combined with the excellent performance for acoustic music I can really enjoy Caro Emerald's Acoustic Sessions where strings come through very well, a thick double bass in the background and clearly in front that lovely voice.

The treble of the E4000 can be summed up as nice and sparkly. There is a lift in the lower treble to help with the clarity and detail retrieval, but nowhere have I found issues with sibilance. It is just a very enjoyable sparkle that compliments the bass section really well to create the exciting and very well done U-shaped signature. Cymbals sit well within the image. They can be clearly heard, but never sound as if they are being unduly emphasised. They sparkle and add to the excitement, but remain polite and inoffensive background instruments.

The treble also helps with the strings, providing a lovely bit of bite for Paganini's violin and when listening to an acoustic performance of the Foo Fighters guitars sound very nice. I do have to keep reminding myself that these are not the much more expensive IEMs I normally use, as everything sounds really pleasant and well balanced. It can be improved upon, but at this price point that will be a real challenge.


The E2000 and E4000 share much of the same DNA in terms of tuning and for me it is clear that the E4000 is a higher end version of the E2000 and that is exactly how they compare. The E4000 is in every way a step up from the E2000. The stage opens up a bit more, the clarity is significantly improved and the imaging is more consistent. With the E2000 I sometimes find little inconsistencies in the imaging where background instruments are emphasised too much, but I have not noticed it with the E4000. Beyond this there are more similarities than differences. The signature if very similar, just matured to a higher quality, and the engaging and coherent sound of the E2000 makes a return in an even more toe-tapping way. Thoroughly fun!

In terms of practical use, the E2000 is a little smaller with a thinner, non-detachable, cable and that does have its advantages, as it is a really diminutive size. However, the build quality of the E4000 inspires more confidence. Sound leakage is slightly less on the E2000, which is why I will opt to use those when commuting over the E4000. When training though, I will happily choose the improved sound quality of the E4000. I would say the E4000 are definitely worth the higher price compared to the E2000 and both offer outstanding value.


The E5000 are definitely a step up from the E4000, although there are also some differences in terms of the signature that can be worth considering. The E5000 have an incredibly engaging sound that is a little more articulate than the E4000, which in my opinion makes them perform a bit less well for acoustic music when compared to the E4000. While the E5000 have a slightly more linear signature (still U-shaped), I find myself preferring the E4000 for classical music. For pop music though the E5000 really shine and I greatly prefer the energy with which they present the music.

In terms of build quality the E5000 is again a step up, but while the cable is technically a better one, I much prefer the more supple and less microphonic cable of the E4000. In terms of size they are the same and I find no practical differences in fit and general use. Even the added weight of the E5000 has given me no issues at all. Again, with both the E4000 and E5000 Final offer outstanding value and the choice will probably mostly come down to the budget you have available. They are highly versatile, fun and comfortable IEMs that are a joy to listen to.

The E4000 are outstanding value IEMs that offer a versatile and engaging sound in a very small and comfortable form factor. They are great all-round, every day IEMs that do not cost a kidney and prove that at the more budget-friendly level there is still a lot of innovation taking place. In this day and age of quickly escalating prices at the top end, Final have provided us with a fresh breeze through their new E-series and I can highly recommend giving them a demo if you are trying to squeeze maximum performance out of a small budget.
