Much like most of the latest generation of KZ earphones , the KZ ES4 is a very comfortable earphone to wear and does not generate in-ear pain. 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 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. 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.

KZ ES4 is the latest in firm’s growing line-up of hybrid

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.

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. 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.

With an EQ you will be able to customize their lower mids and male vocals into absolutely clear and free of mid-bass bleed. Higher mids can be EQ’ed to calm down some of their harshy peaks without getting recessed. The KZ ES4 durability is inline with all KZ earphones from the last 2 years – that are built with the same materials. Expect the same rugged and well-built construction of the KZ ZS10, KZ ZST PRO and KZ ED12.

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.

They never opted for balanced armatures only configurations so far, but the KZ AS10 is the first to stray away from the traditions and to do away with dynamic drivers to offer five balanced armatures per earpiece. And, much to my surprise, this is also the first time KZ manages to produce a product with proper tuning.

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

KZ introduced the new ES4 in-ear headphones a few days ago: they are an evolution of the ES3 which seems to combine the ZS10’s design with the ES3’s simpler components. They are built around one dynamic driver and one balanced armature in a classic hybrid approach. 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. Knowledge Zenith's, the company which is notorious for making so many models, sometimes confusing, sometimes irritating(ZST and ES3 choice) has a good history of producing gems at lower price. KZ ES4 Frequency Response Curve KZ ES4 Frequency Response Curve – Right Side KZ ES4 Frequency Response Curve – Left SideI 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. 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. 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 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. ES4 doesn't hit you with any too obvious flaws. Bass is on the stronger side but it's punchy and controlled well so I think it's fine. Mids are nicely present and very detailed, highs are again very detailed and extended without being too sharp on my ears. All in all it's a very fun listen, but mids are still not full enough and vocals often get stripped from their fullness and reduced to sounding thin and sometimes sibilant. But all in all it's a nice effort for KZ. 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.Qualcomm CSR8645 is a powerful Bluetooth chip. Excellent connection stability, support AptX lossless audio transmission technology, supports AAC-LC advanced audio coding technology, supports EDR Bluetooth enhanced rate. Support CVC 4 noise reduction technology, etc. It is the representative of Bluetooth wireless connection technology on the market. 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. 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.
