The one issue I found with the sound on the ES4 is common to many multi-driver IEMS and that is they sometimes suffer a bit right at or around the crossover frequency where drivers get out of phase with each other. 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. 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. The KZ ES4 mids have full bodied sound with a warm personality and very crisp higher mids. Lower vocals sound energetic and alive despite a mild presence of mid-bass bleed. If you were not into KZ’s new approach with the tuning of the KZ ZS10, you will be happy to know that the KZ ES4 has KZ’s sound signature that everybody loves. The KZ ES4 has a very strong output and if you crank the volume you will feed their crisp higher mids into some harshness.

KZ ZS4: the ZS4 are much more heavily V-shaped, with bass and treble that are much more prominent than mids. Those appear heavily recessed and a bit distant. Bass is almost overbearing, leaking over the mids, while treble is not really detailed despite its large presence. The ZSN are much more balanced, and they have better technical ability, too. Though it is not a radical difference, the ZSN offer slightly wider soundstage, better imaging and better instrument separation. They’re also faster, which leads to percussion instruments being more lively. 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.Wide with tenmak, deep with star lines. Its good, actually better than AAW nebula 2. Its a V shape iem with fairly wide and moderately deep stage. 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 ES4 review: balanced, but not enough - Soundphile Review

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). 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.Seperation was good throughout my audition with only mild crowding on large orchestral pieces. (This again unlike some previous attempts that sounded as if the philharmonic had been crammed in Volkswagen bus and then asked to perform). 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. 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. 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. Qualcomm CSR8645 is renowned for its excellent connection stability, low power connection technology, and high-quality audio transmission.

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. 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.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. 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. KZ ES4 the latest release from KZ with a dual hybrid configuration, detachable cables and plastic housings.

KZ ES4 – In-Ear Fidelity KZ ES4 – In-Ear Fidelity

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. 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 response to custom equalization of the KZ ES4 was outstanding, bass could be empowered into insane levels of punch and depth; lower vocals got very clear and mid-bass bleed was nearly extinguished; highs became extra bright and open-sounding. 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. Living in Glasgow, Scotland but born and raised near Milan, Italy, I got the passion for music listening as a legacy from my father and my grandfather.Leave a Reply Cancel reply Did you like the review? Let me know! Please note that you should write in English, as comments in other languages will be deleted. Thank you! The KZ ZSN are a bit unusual from a design perspective, at least when it comes to KZ standards: the shell is made of transparent plastic (with a fumé finish in my case, but also available in green/cyan and magenta) and the faceplate is made of metal. It is held in place with three screws, placed in the three angles – as the faceplate has an overall triangular shape. On top of the choice of materials, which is new for KZ, the other news is the shape which reminds me of IEMs such as the BGVP DM6. The shell is in fact similar to that of previous KZ earphones, such as the KZ ZS10 or the KZ AS10, so this is not something that we’ve never seen before. This transparent plastic exposes all the innards, so one can easily see the (relatively) large dynamic driver and the balanced armature. The nozzle is made of metal (aluminium?) which should make it much more durable than usual plastic. Like the ZS10 before it, the AS10 does not offer a high level of passive isolation from external noise, providing just a bit of reduction in volume and not much more. Using foam tips helps reduce noise a bit, but they can’t replace the isolation that the shells do not offer. KZ announced a good few headphones in the last several months, including their new flagship the KZ ZS10. A litte after the ZS10, the company also announced what looks like a directly-derived IEM for a lower price tier: the KZ ES4. Being similar in terms of design and a similar yet simpler driver configuration, the ES4 is indeed better from an acoustic standpoint.
