Knowledge Zenith broke again. Novelties showered like a cornucopia. We did not have time to get and discuss KZ EDS, as this Chinese manufacturer hurries to please us with a novelty – KZ ES3 in the review. This time the model is not budget, ask for it almost $10, but the filling is more interesting here than its predecessor.

KZ ES3: Equipment

KZ GR came to me for a month. A model is delivered in a black case, inside of which lie headphones themselves, 2 pairs of additional silicone attachments and replaceable air ducts. The latter represents an original solution for changing the sound, but more on this below.

KZ ES3: Design and Build

KZ ES3 is a hybrid two-door model. Those in each earpiece are placed one dynamic and one rebar radiator.

At the same time, the dynamic driver is large enough – 10 mm, which allows us to hope for its high-quality sound, which will additionally form the reinforcement component of the model.
It is to be formed and enriched, because, according to the manufacturer, the KZ ES3 uses 30095 units from the legendary Knowles office, which is a radiator not of the full range, but a “people”. So here it will be possible to do without a crossover.

But in terms of design and materials, headphones go far beyond their cost. Appearance a little steampunk, but I think most will like it.

The bowls are made of metal, most likely brass, are rather heavy and are firmly assembled. The cable is of average thickness and has a silicone braid, an L-shaped plug.

Plastic cases, anatomical. The cable is again removable, on two-pin connectors.

The design pleased me, the manufacturer I like, but because KZ ES3 I have already purchased and look forward to. What do you want?

KZ ES3: Sound and Remote control

As for the specs of KZ ES3, there is nothing to say with certainty about anything – we all know the love of Knowledge Zenith to exaggerations, but we will try. The range of reproduced frequencies is promised from 20Hz to 40KHz, impedance is 10Ohm, and sensitivity is 106dB.

You know, it’s very difficult to assess the sound quality of similar headphones, if earlier the music was listened to by SoundMAGIC E80 and JVC HA-FRD80. But of course, no one will buy this model in the hope of a, particularly detailed sound. Well played pop music, I listened with pleasure to Robin Schultz and R. City, electronics go well in the manner of The xx.

I did not get to practice in the hall under Bring Me The Horizon, the sound is just disgusting, as though I switched the speakers. This applies to absolutely all heavy music – KZ GR for this do not suit.

Removable air ducts have a thread and change quite easily. Personally, I preferred a sound with black channels, with which the bass turns out to be deep enough for their money. In the red, all the way around – due to the open design low frequencies practically go away.

And the rest of the sound should not expect something unusual. Here the scene is tightened, “sand” is heard well, especially at high volume, the middle and high frequencies are quite distorted. Sound insulation is mediocre, which is facilitated by the semi-open design of the bowls.

I got a model KZ ES3 in the test with a remote control, on which there is a button for controlling the player/calls and a microphone. Strangely enough, the quality of voice transmission is quite good.

KZ ES3: Ergonomics

Despite the heavy bowls, the headphones are ergonomically shaped and do not fall out. Landing can be either BTE or classic wire down.

Because of the tenacious rubber coating, the cable constantly clings to clothes and causes discomfort. The latter is relevant when playing sports when the cord is skipped under the clothes. For walks, headphones will fit, for jogs and halls – not very much.

KZ ES3: Competitors

First I compared the monitored headphones with the reference, for their money, Xiaomi Piston V2, and V3.

No, the level of Xiaomi plugs is clearly higher than Knowledge Zenith GR.

The sound of Panasonic is slightly softer, but otherwise the same level, KZ win by its appearance, materials, and bundling. But with respect to the ergonomics of Panasonic, they go a little ahead – the bowls are lighter, the cable is smooth.

KZ ES3: Conclusions and Reviews

I’m sure many have just learned about such a headphone maker as Knowledge Zenith. But as it turned out, under the wing of this Chinese company, quite good budget solutions are produced.

There are even IEMs with several dynamic emitters. And the hero of the review proved to us that for ridiculous money one can get good in-channel headphones, with a nice design, good materials, and assembly.

Great hopes for sound should not be laid, but for pop music, indie, electronics – a great option.
