Speaking of technical ability, the KZ AS10 is not half bad by any means. Soundstage does not extend to far-reaching distances and does not reproduce the feeling of being in a large hall, and neither has enough extension to the sides and depth to recreate a feeling of being in a space, rather than having the music played directly in your ears. It often feels a bit congested, as if music was compressed in a small space. Imaging is good enough to come to soundstage’s aid in allowing the listener to locate the instruments with acceptable precision. With a form factor very similar to the KZ ZST , the KZ ES4 offer the same outstanding level of comfortable and secure fit. Regarding size, the KZ ES4 are not as large as the KZ ZS10; instead, they have a footprint more inline with the KZ ES3, KZ ED12 and smaller than the KZ ZS6. An EQ adds a jaw dropping amount of brightness and become noticeably more detailed. Piercing highs can also be efficiently eq’ed to reduce their strength. The KZ ES4 features 4 drivers in total, distributed in 2 per earpiece. The dual driver setup includes 1 balanced armature and one 10 mm dynamic driver, each driver will independently be responsible of reproducing different audio frequencies – the dynamic driver will take care of the lower end while the balanced armature will resolve mid and upper frequencies. The ES4 sounds like a downgraded ZS10 in terms of technicalities; instrument separation is good but not exceptional and it can’t withstand complex situations without muffling things up a bit, while soundstage has limited width and imaging can only give you a hint of the instrument’s position.

Tries to get into upper bass register and bleed towards mid, but is now in control due to tenmak tips. It is to punchy and is distinct(I don't like that much punch) but is still maintaining a fundamental tone, so I can tolerate. But on slow, classical or orchestral songs this mid bass is very good. It defines the weight of instruments.The cables are the same one that comes with the KZ ED15 and KZ ZS10 with a dual double helix braided design and very rubberized finish. The connector of the cable is the same bi-pin 0.75mm of all KZ earphones with detachable cables; specifically they use the angled connector (like the KZ ZSR , KZ ZST and KZ ZS10) and not the straight connector that came with the KZ ZS6 , KZ ZS5 and KZ ZS3. The ES4 is made out of a hard plastic shell and comes with a removable cable. These earphones feel pretty solid, but with such a hollow and large casing I would be afraid to step on them. Comfort is rather good, I especially like the ergonomic shape and the lighter weight of the plastic casing compared to metal earphones that often fall out. So DankPods has mentioned both models in his Xmas and Raycon 2: The Rayconning videos. But as someone looking to buy a pair;

The KZ ES4 belongs to the newest generation of KZ in-ear monitors and shares some design similarities with the KZ ZS10 , like the transparent housings and the characteristic divider board with the KZ logo which can be found inside the rear section of the housings.

The ES4 can occasionally display this behavior but for the most part this was something you had to be looking for to find and not a major distraction. Let’s face it: while KZ headphones often offer good value, they have never been great soundwise. Yes, they are good… for the price. After many, many headphones plagued by tuning issues, the KZ AS10 are finally balanced and without the spikes and dips that characterise most of the company’s products. No more aggressive upper mids, no more overpowering mid-bass, no more fatiguing treble. This is finally a KZ product that gets tuning right. The irritating thing is that it is more than probably just a chance, as KZ is notorious for using off-the-shelf drivers without any proper tuning work. Extremely tight, if you are moving from single dynamic driver. It extends when required and doesn't interfere with musicality. But when called for, it shakes. Bass drops and bass line is crazy plus it stops somewhat pretty correctly.KZ ED16: the ED16 stand out because of their instrument separation and soundstage, which are way better than those of the ES4. Detail is also better in the treble and bass regions, while in terms of tuning, they have more emphasis on the usual region across midrange and treble. Midrange also pops out more, yet the general impression is not that of better balance. What really prevents the ED16 from being better is the relative unbalance. KZ ZS10: the midrange on the ZS10 is much more recessed and much less balanced; treble, too, is way less present and detailed. It almost feels dull in comparison to the AS10. The only point in common is bass, which is however not as emphasised on the new model. In terms of technical ability, the AS10 win in terms of detail, but the ZS10 are better on the soundstage front. The rest is a tie. I would say that the KZ ZSN are good for most genres; their V-shaped tuning makes them especially apt for modern genres, but it’s up to one’s taste in the end.

KZ ES4 - Review | ThePhonograph.net

Front-facing lights are designed with a 1.5w high-brightness LED light to illuminate the path ahead of you and to increase your visibility to others around you.During our extreme bass tests the KZ ES4 were able to handle 40% of the maximum power of a Fiio E12 amplifier while being set to high gain and with bass boost turned on; a custom basshead EQ was used. The extreme amplification and equalization, made lower frequencies of the KZ ES4 achieve a massive increment of mid-bass punch and sub-bass depth that even provided a crazy basshead level of impact and rumble way above the Xiaomi Mi Pro HD, Monoprice 8320 and even stronger than the Xiaomi Mi In-Ear Headphones Pro but not as impacting as the Sony MDR-EX650 , Sony MDR-EX800ST and Pioneer SE-CX8 . The fact that the KZ AS10 is balanced and actually pleasant comes therefore as a surprise. This may be the most interesting IEM made by KZ due to this, despite not having the same technical prowess as other headphones in the line-up.

This new shape is much more typical of higher-end IEMs – though it’s of course not the shape that indicates the positioning of the headphones (as Campfire Audio, among others, taught us). What’s positive about this design choice is that the KZ ZSN are really comfortable, as their shape is kind of neutral to the ears. There are no sharp edges or other similarly polarising features, so it’s easy to find the right position that is comfortable. The relatively small size also helps with this – my girlfriend, whose ears are much smaller than mine, had no trouble in wearing the ZSN and finding the right fit.

While listening to music at a moderate volume their sound leaking levels will be imperceptible by nearby people. If you set the volume to the very maximum people next to you will hear a very subdued leakage (if first you do not become deaf by their super strong volume output) Instruments can be a little coloured in image but are precisely placed in stage and not like ZS10 weird stage effect. Pace, Rhythm and Timing is also good, but overall it is a little incoherent(way better than many hybrids, but still, not like my 64audio).Noise isolation of the KZ ES4 is highly efficient, with a level of reduction of surrounding noises far stronger than most average earphones. You can set your volume within moderate and they will still provide a near absolute isolation, by cranking the volume just a bit higher the will isolate you completely from noises. The KZ ES4 is the newer updated version of the KZ ES3 , inheriting some of their main technical specifications like: dual driver, plastic housings, detachable cables.
