KZ ES4 HiFi Hybrid In-ear Earphone Wired Earbuds

I cannot say enough about these remarkable headphones. I found out about them in music forums where many folks play live on stage with in-ears. They weren't simply using them casually. The semi professionals and pros were using them as solid backups and volunteers as their mains. I must've had at least a dozen comments raving about them. I purchased a set as well as Mee M6 Pros (also a highly recommended IEM for the money $45) and compared both with my Shure se215s (the industry entry level standard -- fantastic in ears). I was disappointed the moment I put them in as they were thin and lacked the low end everyone raved about. I reached out to several owners. ALL of them said it was a seal issue, and I needed to buy foam ear tips. The minute they went in my ears with foam tips I was speechless. What wonderful balance with a very present but controlled low end and perfect clarity without being shrill. And this is coming from a pure audiophile. I couldn't believe this kind of tone could come from $20 earphones. And dual drivers?! I did a lengthy side by side comparison of the same various song clips with this set and the Shures and they are very very similar in tone and sound stage.This is a bare bones package that comes with the ear phones, silicone ear tips (I recommend buying the 5mm Comply or Rebound foam tips separately), and memory wire--no bag, 1/4" converter, foam tips, ear cleaner, or secondary wire. The earphones themselves are larger than the Shures and M6s, and even though they stick out of my small ears a little more they were comfortable and I got a good fit with the memory wire over the ears. They felt surprisingly well made in hand and had smoother fit and finish than my M6s by comparison. The M6s were much brighter and clearer almost to the point of being shrill with very present mid highs. At $50 they came with nicer accessories and bag and would be a good fit for anyone wanting a clarity machine, voice podcast only, or something to lay down or sleep with (since the earphones are smaller). I recommend "burning in" both sets for 4-6 hours playing continuous music at a medium volume to take the edge off.I simply can't think of any cons other than the larger earphones, lack of accessories, and the need to buy separate foam tips. If you have $100 to spend and need pro IEMs I would still recommend the Shure se215s first since they just price dropped to $89, have excellent fit, superb longevity, and come with a host of accessories. However, if you need an inexpensive pair for your bare bones budget, a backup set, or a casual set I cannot recommend them enough.

Dear Seller , I want to tell you that i recieved my KZ ES 4 yesterday and everything is looking fine but The volume of right ear side is very low that i can barely listen anything even i have tested in 2 dacs and 3 phones and i think its a manufacturere defect. I am satisfied with the delivery time and looks of earphone but i dont know what to do now . Do i get new piece of earphones if this is in warranty or maybe i have to stuck with this faulty piece :( kindly support me ! Coming to Sound Quality i noticed from left side , i can say that the sound is simply awesome and super detailed , not so wide soundstage but you will get satisfy , bass is tight , mids and highs are normal and obviously you can tune easily according to your taste because the sound production range is super high on this earphones . You can use with any source and they will shock you each time . I have noticed that many peoples compare the KZ's from their Lows,Mids,Highs but you should think that these are monitores (iem) and they can perform at any stage and with any type of tuning so dont get confused between many kz's . all are good but you should tune them .Build Quality is super dashing looks , they are sturdy , lightweight ,very premium finish ,wire looks awesome , eartips are super bad !!

Let's start from shipping. It was fast, only 13 days, would be 11 if I ordered them day sooner. Package is great, gives premium feeling. Cable is perfect, it's twisted and it looks way better than regular straight cables, plus this gives more room for durability . IEMs are great too! Awesome build and design, but be aware, if you have smaller ears it may not fit you...Sound quality is great, response to EQ is amazing, if not the best for this price range. For example, you can boost up bass up to abnormal levels without distortion. Lows meds and highs are great, it may lack a bit on highs, but only on specific songs, with bit of EQ tuning you can get the best out of this IEMs!So in the end, I am very, very satisfied with these IEMs and can easily recommend them to anyone. Great ''beginner'' chi-fi IEMs, you won't regret it.

Auriculares "In-Ear" con muy buena calidad de sonido. Se escuchan muy bien las bajas frecuencias.No son demasiado pesados. He estado varias horas seguidas con ellos puestos y no he tenido ninguna molestia. Se adaptan muy bien a la forma de la oreja (por lo menos en la mía). Además, los alambres que llevan los cables son muy prácticosLas conexiones de dos pines de los cables con los auriculares son muy fuertes, lo cual es bueno para evitar desconexiones no deseadas.El único detalle es que si te fijas en los cables interiores, ya que la carcasa es translúcida, da la sensación de que la calidad del ensamblaje no es muy alta. Aún así, no parece afectar al uso normal del dispositivo.

Es muy buen producto, son muy buenos audífonos, suenan muy bien, tienen buenos graves y alta fidelidad. En costó beneficio y para mí parecer son muy baratos y muy buenos, son de calidad y de bajo costo, no he escuchado otros auriculares de esta marca, es decir, no he probado otros modelos, pero estos pueden competir con muchas marcas reconocidas. Los KZ ES4 me gustaron mucho los recomiendo altamente, pero lo que más me gustó es que el cable se puede sustituir por un módulo Bluetooth y además si se arruina el cable puedes comprar otro de repuesto. Son geniales, el único detalle que no me gustó esa hay muy pocos colores, deben hacer de más colores, así habría más demanda y venderán más. pero en general su sonido y diseño me gustaron mucho

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.

Suggestion

not that much of Ear-tips, I think better silicone or foam will provide better comfort

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!!!

For me, KZ ES4 are the best earphones under 40 euro I've ever used. Bass and trebles are nice, mids are a little too bright. Comfort is better than expected, but not with default tips. I recommend to buy some softer tips. Cable is good enough for common user, but I had problems with one connector, until I finally lost one of the earphones. Price is just a cherry on top. Great earphones in this price range, can't recommend more.

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.

Suggestion

nada!

I got these babies yesterday. My kid brought me the ZST Pro and I got the ES4 and hands down I prefer the ES4 over the ZST Pro. The bass on the ZST are punchy and the highs are a little unbearable but the ES4 is very clear and the bass on them are perfect. Haven’t been able to use it during live performance so I can’t give you a complete review but what I can say is no matter which one you prefer KZ is a great product.
