KZ ES4 HiFi Hybrid Auricolari Cablati In-orecchi

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 !!

Yo compre estos auriculares por recomendación de algunas review en youtube donde explicaban un poco su experiencia de audio con estos auriculares y me pareció que no estaban nada mal.
Cuando los conecte a mi laptop y reproduce música en formato flac normalmente yo suelo escuchar rock, baladas,instrumentales,algo de metal, etc, me dejo un buen sabor en el audio que resivi pues lograba apreciar muchos detalles que anteriormente.
El volumen del audio que resibes es fuerte y claro por lo que yo recomiendo que si los adquieres mantelos en un sonido entre un 50 a 70% de volumen ya que si subes demasiado el volumen puede llegar a ser molesto.
En la comodidad de los audios en el oído es buena y no cansa mucho, los he estado usando por jornadas de 3 horas y no siento molestia alguna .
Recomiendo estos audífonos para la persona que use unos audifos que escuche su musica en los audifonos de mala calidad que vienen con su telefono,no había oído, no soy un profesional en esto del audio pero esto es la experiensa que tengo con ellos alrededor de 1 mes.

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.
