  • Snapping, crackling, popping, or no audio on one side

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

    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.

    Best quality Soundphile Earphones at affordable price
    Color:Black Size:without Mic
    This Earphone was so good having the good deep bass and good highs, The new generation copper cable was so nice best in the range, balancing the bass, mids, highs bu using equalizer which works very effectively, Best Noise cancellation, works to suits your needs on best equalizer player apps.Design was too good to visual. The cable detachable to earphone was good for longer period use.
    not that much of Ear-tips, I think better silicone or foam will provide better comfort

    KZ ES4 - Valen tu dinero
    Color:Black Size:with Mic
    La combinación del nuevo driver dinámico de grafeno y el armature driver hacen que usar KZ ES4 sea como estar en la fila de adelante de un concierto. Habrá quien sea fan de este tipo de sonido, considero que son audifonos para disfrutar música electrónica y similares; medios suficientemente claros y frecuencias altas "bien" sin llegar a ser más. Por su precio y sino cuentas con un modelo anterior, te recomiendo probarlo por su relación costo-beneficio.
    KZ!!!!! por favor mejora tus cables & eartips, todos los odiamos!!!

    É realmente espantoso que um fone com esse preço chega tão próximo de seu irmão Kz zs10. O modelo foi comprado anteriormente e testado, com som indiscutivelmente limpo, bem dividido e de pura qualidade. Este fone possui suas frequências bem divididas, sem sobreposição, som agradável e construção aceitável. Diferentemente do Kz zs10, o Kz es4 não incomoda, justamente por ter uma estrutura menor. Apesar de sua inferior quantidade de drivers, não compromete sua posição no ranking em relação ao kz zs10. Vale muito a pena.

    É importante destacar que ambos possuem qualidade de som incrível, limpa e equilibrada.

    This is better than I could ever expect from a €15 IEM. The sound is remarkably good with a nice low end and good highs. Even though I am not a fan of in ear stuff because my ears are weird (Iguess) , these sit quite comfortably in my ears.
    I like the looks too with the choice of three colours.
    It has a nice cable where most brands would sell for €15 alone probably.
    The highs can sometimes be a bit too loud compared to the rest, but that's minimal.
    No other real cons.

    Amazing for the price
    Color:Black Size:without Mic
    For me this are more comfortable than the ZSRs because the design is... simpler, more a universal fit.

    The sound is excelent although not quite reference as they claim (a little heavy on the bass... but this will probably be a good thing for most people), I own $300+ earphones which are better, but again, for the price KZ are truly impressive
    The worst about this is the not so good seal, which is a most for proper listening so be aware of that. But that being the worst means that, as with other KZs, it's almost impossible to beat these in their price range.

  • Tomas Jokay
    Another good iem by KZ
    Color:Light Cyan Size:without Mic
    Good amount of bass
    Very good depth and clarity of the bass
    Decent mid range
    Not piercing treble.
    Narrow and not large soundstage (similar to ES3)
    Very sensitive (every phone can drive them without any problem)
    Good built quality (probably as same as ZSTs and ES3s)
    Lacks a little bit more clarity in treble which i like on ES3.
    I would like to hear a little bit more presence in mid range (seems slightly recessed).

    KZ ES4
    Color:Black Size:without Mic
    -Ses kalitesi güzel, sesler detayli ve ayirt edilebilir. Basslar kuvvetli.
    -yeni örgü kablo cok dayanikli duruyor ve acikcasi eski tip kablolarina göre gayet basarili buldum.
    -kulakliklar kaba degil, kulaga oturusu guzel rahatsiz etmiyor.
    -malzeme kalitesi ve iscilik fena degil
    - tizler felaket, daha önceden dinledigim birkac parcaya sirf tizlerde asiri bozulma oldugu icin katlanamadim. Tizler disinda acikcasi bir kulagima batan bir bozulma olmadi acikcasi detaylar falan cok güzel ama tizler malesef büyük eksi.
    -kulakligin ses cikis kismi biraz genis silikonlari cikardiginizda takmasi büyük sikinti olabiliyor. Baska silikon baskliklara uyumlu degil.
