    KZ ZS4
    Just received these in the mail a couple of days ago,

    These are a dual driver IEM with one Dynamic and one BA driver in each side.
    Detachable Cable, i did not purchase the mic version
    S,M,L eartips

    Fit and Finish

    The construction is smooth with no hard or sharp edges. At this price point you are dealing with simple plastics no aluminum.

    The cable is flexible enough does not seem to tangle or present much in the way of microphonics. I do think the cable yoke is a bit farther down than usual though. Time will tell if that is a issue.

    KZ is finally putting a lip around the nozzle, this is something that bothered me about their other models; so they get a point from me on that.

    The fit is always a personal experience, but for my small to medium ears these are comfortable and do not seem like they would fall out. The over the ear cable does have a wire and works well for me.

    Sound

    Midrange
    I find these a bit midrange forward and they are bordering on harsh for me if I am really driving them.

    Bass
    I have tried multiple tips and feel like I can achieve a good seal. Sometimes too good to the point of a suctioning effect. Maybe I'm blocking the vent/port. That being said I don't hear as much in the way of sub bass as I would like. The upper bass is present but does not hit hard by any means.

    Treble
    I'm finding that the treble is adequate for general use, but I miss the sparkle I'm used to hearing in the KZ ZS6

    Soundstage
    I don't find theses lacking where soundstage is concerned, however they do not offer anything new. If there are issues here for me I would attribute that to the lack of sparkle I mentioned earlier.

    Summary

    I plan to use these as my grass cutting IEMS for two reasons: they are cheap, i.e. expendable and they do a decent job where isolation is concerned ( At least for my ears ).

    Первые наушники фирмы KZ
    Новинка в очень удачном дизайне лично для меня, раньше стороной обходил фирму эту чисто из-за дизайна самих наушников, хотя звук все хвалят, так вот когда увидел эти то они побудили меня её попробовать их приобрести, понимаю что модель не высокого класса у KZ но средний точно есть при такой цене. Брал без управл. пульта.
    Классный дизайн
    Комфорт посадки в ухо
    Звукоизоляция на хорошем уровне с базовыми амбушурами
    Я не меломан конечно но звук очень порадовал!
    Строение проводов интересное, никогда с такими не было у меня
    Возможность менять сами кабеля, так же есть кабель с портом type-c отдельно продается
    Минусы только то что соединительная часть провода с наушниками смотрится не очень надежно и со временем может расшататься
    К покупке рекомендую, но можно ещё дешевле найти
    Всё субъективно, но рекомендую

    beautiful earphones
    i principle decide to buy this in-ear phones because i knew the feature of noise-cancelling wich is very useful, and yhen the color is so bright and beautiful that leave an impact and make you feel better, the quality of the audio for what i like is very good, not too much base and light audio.

    so

    pro: color, noise-cancelling and audio quality

    cons: some people like more base in the audio

    Ses kalitesi çok iyi. Malzeme kalitesi mükemmel. Kulakta ağırlık hissi yaratmıyor fakat boyut olarak bana biraz büyük geldi. Dış sesleri duymaniz neredeyse imkansız. Max ses seviyesi ideal.
    1)I gave it 4 stars because it was a little big size.
    2)The sound quality and the material quality is good. It doesn't feel heavy in the ear.
    3)You never hear outside sounds.This is a big avantage. It is a disadvantage for me to be on the ear.
    4)I'il recommend this version to my friends. But other versions are as good as this.

    KZ ZS$
    Para los que no conocen la marca KZ, es una marca con precio muy económicos y una calidad que supera por mucho a los de su precio, inclusive a los audinos de Xiaomi que para mí fueron una decepción.
    Este modelo en especial se escucha muy bien para música electrónica que es para los que los uso, además el diseño es increíble, se ajustan muy bien a los oídos y no se caen gracias a su cable ajustable.

FAQ for KZ ZS4 HiFi Stereo In-ear Earphone Music Earbuds

  • Snapping, crackling, popping, or no audio on one side, what can i do?

    1. Make sure the 3.5 mm audio jack is fully plugged in. The straight input connects to your headset, and the L-shaped input connects to your audio device.

    2. Check that your audio source is on and working.

    3. If your audio source is a computer or laptop, try adjusting the configuration settings.

    4. If you still hear distorted sound, try a different audio source and an alternate cable.

  • Phone not responding to button presses?

    Make sure that the headset plug is securely connected. For multi-press functions, vary the speed of presses when you use the remote / mic.
  • Microphone does not pick up sound, what is wrong?

    1. Make sure that the headset plug is securely connected and that the socket is clean and clear.

    2. Check that the microphone—located on the back of the remote—isn't blocked or covered.

    3. Make sure the straight-end of the plug is connected to the headphones and the angled L-shaped plug is connected to the audio source.
