KZ ES4: the ES4 are more balanced and neutral when compared to the ZSN. They offer less bass presence and more treble extension, while keeping the mids front and centre. The ES4 tend to be more detailed throughout the spectrum, and they also have slightly better soundstage width, imaging and instrument separation. They are not as god in terms of speed and control, though, nor are they when it comes to bass extension. Although the tuning is generally way better than that of previous earphones, it is not devoid of criticism. While there are no strange spikes and dips, there is a bump in the mid-bass area that introduces warmth to the signature. What’s great is that there is no aggressiveness whatsoever, anywhere in the spectrum.
KZ ZSN review: a step in the right direction KZ ZSN review: a step in the right direction
The dynamic driver has a 10 mm diameter and KZ says there is a layer of graphene over it – I highly doubt it, since graphene is still not suitable for industrial applications and is confined to research labs around the world. It seems KZ is using the same balanced armature as that on the ES3: the Knowles 30095. They say it is a custom unit and I hope so, as the entry for the 30095 on DigiKey reports a frequency response of 120 – 7,400 Hz, which appears quite disappointing. The sound that leaks out of the KZ ES4 is very low. 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) I would like to say that KZ finally nailed it with the ES4. Alas, that would not be true. The KZ ES4 is still plagued by a superficial tuning job that does not unchain the true potential of the drivers. This is not to say that it sounds bad, though, as I enjoyed listening to it and I still think this may well be one of the best earphones made by KZ – I consider it way better than the ZS10 in terms of tuning. 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.Given their warm yet balanced tuning, the KZ AS10 are good all-rounders that can take on most genres. 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.

Shozy Hibiki Mk2: the Hibiki Mk2 are, among the headphones presented in this comparison, the most similar to the AS10 in terms of tuning. There are some key differences, though: the AS10 are more balanced, thanks to more treble presence and better extension; midrange is also less warm, and bass is a bit more controlled. In terms of quality, the AS10 seems to have better detail and better instrument separation, which lead to clearer sound. Soundstage is where the Hibiki win, as they are able to present music in a relatively wide space.
Treble is where the ES4 has a clear advantage over other KZ headphones, as it is a bit more extended and it has a nice resolution which leads to a good perceived level of detail. Now, the thing is it doesn’t hold a candle against headphones that really have good extension and good detail (e.g. Tin Audio T2), but the ES4 can hold its own in its class. Don’t expect anything too fancy; you can hear a good few details, but all the micro-details that often make the difference in telling a really good product from an average one are not there.

Isolation-wise the KZ ZSN are decent, but alas distant from the 26 dB noise reduction touted by the manufacturer. Ambient noise gets reduced by a little bit, but I could not avoid raising the volume while on public transport. Sound & Specs 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. I am quite surprised by what KZ achieved with these earphones. The KZ AS10 are amazing in their own way: their tuning is balanced and enjoyable, there’s a very good technical level and they’re comfortable. They’re not perfect, though, as there’s still some work the tuning could see – a bit more clarity with a slight emphasis on the upper midrange and more treble extensions would make them even more interesting. 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.

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.

Midrange is certainly recessed, but not as much so as to sound distant or as to make you wish for more volume. The signature is balanced enough to leave midrange enough room to breathe; instruments (including voices) are placed in the mix so that they are always clearly audible. Tonally-wise, midrange is on the warm side, but gently so: mids stay balanced and the upper range is not too far behind the lower range. This presentation is quite relaxing and enjoyable, especially if you listen to acoustic instruments. It’s decent even if we take a few other matters into account: detail is good enough to deliver the necessary nuances, but you never get to taste the finer ones. Even a few smaller details get lost in the mix, though that’s to be expected. Speed is good, though, so fast transients are rendered with impressive accuracy for the price range the KZ ZSN are in. 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). This and the ED16 are the best KZ mids to date. Whoever at the factory that was supposed to scoop the mids must have had the day off as they are more present in the mix than any other KZ in memory. I still hear the ES4 as a V (and the FR graphs prove that out as the mids are nearly 5db behind the treble and 7-9db behind the bass) but the sound is so well proportioned that it does not listen like a big V but more like a shallow V with a lively presence region. 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. 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.
Make it Shine
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. 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. TRN V80: the V80 are V-shaped and very much so, so it is no wonder that they end up having more emphasised bass and much more prominent treble. In terms of quality, then, there are a few differences: the V80 have deeper bass, but not as much control; midrange is more balanced and frankly enjoyable on the AS10; treble is more spacious and airy on the V80, but it is also much more easy on the ears on the AS10. In terms of soundstage the two are similar, but in terms of instrument separation and imaging the AS10 win by a slight margin.
