Very good quality

Sound quality is amazing ..... Before plug in ear , always recheck whether the volume is less than 30% or 40% ..... Other wise you will loose the diaphram 😄 Darm good😄

great bass sound good tone!

Unfortunately they broke after 1 month use. The connector parts came off loose and wont connect anymore. Disappointed.

Excelente sonido me gustaron mucho y en tiempo y forma

So far I think they are great! I haven't used them with a band yet but when I used them with my phone the sound quality was great. They are noise canceling and had a good range of sound. The only thing that I would mention is the chord seems a little flimsy. It is in good condition now, but seems like the chord could break easily. I think as long as you take care of them well they should be fine! I saw some reviews about them being hard to put together but I thought it was pretty straight forward. The instructions had a picture to help. OVERALL: Great find for a great price.

Easy KZ ZST Colorful Hybrid Banlance Armature with Dynamic In-ear Earphone 1BA+1DD Hifi Headset (colorful ZST MIC) I have slowly been buying and testing out these so-called Chi-Fi IEMs. It first started when my friend turned me on to the MEE earbuds. Went progressively up from the low-cost Sports oriented then on to the more exotic material casing and drivers including my first pair of armature driven IEMs. I then discovered Xiaomi and 1More when they became the talk of the town with dual and triple drivers. While the experience has been progressively more positive with each discovery, it was still mostly dependent on word of mouth and through American marketing presence that I come to discover them. That is until I discovered the website audiobudget.com and the matter of fact review of all the wonderful Chi-Fi name brands that I have never heard of, with ZST being one of them. I have had my eyes on the KZ ZST for some time and when the opportunity came up for a good deal and fast Prime shipping, I ordered one. You see, part of the love of Chi-Fi is the patience to wait for a very long time for orders to arrive on a slow boat from China (literally and metaphorically). Regarding the ZST itself: As is with all IEMs, a lot of the factors are personal and subjective. We all vary in the physiology of our ears as well as our personal style and application of (any) technology. Subjective issues like fit and ergonomics will vary by the person. In the case of ZST, I will say that it is unnecessarily large design in the sense that if there was ever a concept of a pair of "statement" IEMs, these are them, in conjunction with the colorful neon magenta, blue, and silver color scheme. You can't miss seeing them worn though I have seen worse, too, much worse... I will state that I have had many others with just as good or better audio performance IEMs that are significantly smaller thus much easier to wear for my puny ear canal cavity. When it comes to audio quality, these are definitely at the upper end of the spectrum of Chi-Fi IEMs. There is a slight V and I think that is a plus as, again, subjectively, I think a truly flat sound is just that, flat and unexciting. With the ZST, the highs are clear without the fatiguing sibilance. The mids are not much recessed so in conjunction with the non-piercing highs produce warm vocals. The bass is adequate without the risk of most people identifying you as a bass head a-la Beats products. It has almost tight enough mid-bass without an overwhelming sub-bass (I'm a tight mid-bass snob, so that is actually a compliment). The audio performance putting these smack in the middle of a good daily performer that is usable on all genre with classical being on one end and EDM the other of the spectrum. We can not discuss audio quality without discussing the IEM tips. After the driver and tuning, they are the single most important portion of the IEM that enables the product to work as a whole. You see, without the tip forming a proper seal, you will be missing out on a majority of the quality aural waveforms that the IEMs require in order to perform as designed. An analogy I heard from one of the audio test sites is imagining a pair of headphone on your head (or actually put one on). Most of us have experienced this in that, on some (most) headphones, you put both your left and right hand on the left and right phone cups and squeezed, or, pushed them in closer toward your ears, you will hear a different sound reproduction (and often times an improvement). Now, the IEM works even closer in your ear and without a proper seal, the best IE would sound less than optimal. So, do spend the time and effort to find your size that is both comfortable and create the best seal. In this case, I ultimately ended up with the small tips that were most comfortable to me at a slight loss of a better seal and bass performance as a trade-off for longer wearing time. Accessories is a mixed bag here. Detachable cords are always welcomed for longevity although the choice of the memory wire is yet another subjective issue. Some people like them and some not. I personally don't mind them that much but will note that it does take longer to adjust and fit in my ears. However, once properly fitted, they certainly do stay in place better. So, as is with most things in life, it is a trade-off of one over another, in this case, comfort vs. fit vs. convenience. The detachable wires were a little difficult for me to put in but I hope that also means that it won't come off easily. I like the silicone coated wires at the standard length (which is always just a little shorter than we like to be reminded of when tugged). My ZST came with 3 silicone tips which I would say is pretty barebone. I would have been more impressed if a medium size conform tips were also included. Others also included tips like double or triple flange tips. But some are more useful than others. Perhaps at this price point that is to be expected. While reviews by others showed an included carrying pouch, my version did not come with one. Mine arrived sealed so maybe they missed it at the factory. At any rate, I would certainly take this opportunity encourage more manufacturers to include hard/soft shell cases instead of pouches. They just make the IEMs feel that much more "upscale" if you would ever associate the world upscale with Chi-Fi. The packaging itself is just meh. Serviceable, but nothing that wows nor impact the performance of the IEMs. In conclusion, I'm very happy with my KZ ZST Colorful Hybrid BA IEMs. They sound great to my ears, did not cost an arm and a leg that I would be sad if they broke or were stolen, and is a good daily driver that people cant possibly not notice when I am using them.

Excelente calidad.

BE CARFUL! When I plugged them in they were amazing! Great sound quality, highs and lows are balanced well with a clear full sound. Sound like they should cost 3 times more. BUT..... All of the sudden a deafening high pitched whine starts after a few minutes of use. It Is horrible and I'm afraid to use them now. I've tried 4 different times and each time I get comfortable and that maybe it won't happen - IT SHOOTS THAT SOUND!
