YINYOO KZ-ZST Colorful Hybrid Banlance Armature with Dynamic Ear Earphone 1BA+1DD HiFi Headset KZ in Ear Monitor Headphone Wired Earbuds IEM Earphone Gaming Ear Buds (Colorful/zst Without Microphone)

What I was looking for: After accidentally buying some IEM's without knowing what it was (TNSO) (last picture), I was determined to find another pair. I couldn't get the same ones (went unavailable), and didn't know what to look for. When I finally stumbled upon more, I was plagued with trying to find some that had balanced sound. As someone looking to produce music, I didn't want anything filtered. The best ones actually were cheaper than this but wouldn't be able to hold up more than a few days. Why I chose these: It seemed like I was going to have to settle with some elevated bass. With the reviews as good as any on these, the price, replaceable cord (thought it'd be cheaper to just buy a whole new pair), I decided to get them. Sound Quality & Bass: My ears aren't well trained. But I had some help learning about headphones with balanced sounds, and got recommended some headphones in my budget that many producers use (pretty much only producers from the looks of those reviews). I got them, was testing them out, and pitting them up against these earbuds. I was shocked at how similar the quality was. Only difference is that I could then tell the elevated bass, which this definitely does have. Probably not to the liking of those who want super elevated. While I don't even like it myself, it doesn't bother me with these. So if you want super elevated, these probably aren't for you. But I can say that these might be the most accurate to sound you can get for casual use. Which is what these are for, I use them for casual listening, internet scrolling, and video sharing skype calls with my bestie. I pop the more professional headphones for working. I almost felt bad though for getting the headphones when these were so similar. The elevated bass was definitely a problem, but if not for that, I probably could've gotten away using these for producing too. No joke. But it probably will be better to produce with headphones rather than earbuds. The 3d illusions are more immersive. But truly I think I could just use these had it not been for the bass, I wouldn't have known that before though. Noise Cancelling: I think the noise cancelling on the accidental IEMs were some of the best, people could be talking less than a foot away from me & me not even know they were there until the song ended. I don't think that's happened with these, but I don't have trouble with hearing external noise over them. I don't always listen to loud stuff but I do a lot of scrolling on Instagram, tik tok, or listening to K-pop, which is all pretty full & busy sounds. So I'm good on that. Longevity: I'm over a year in now, got these November 24th 2021 (first 2 pictures), It's November 30th 2022 now (3rd picture). They're holding up good. I think the cord has changed color, the clear plastic, from food stains most likely. I've had no issues with the in ears, and the cord seems like it's doing just fine. It tangles pretty good. It's not hard to untangle but the part that bends over the ears makes it difficult. I don't find that deterring. I think the way these cords are made, are just less likely to have issues. And it's really an unbeatable price for sound quality at $17 when I bought them, even if they only last a year or two. I suspect these will hold up longer than any I've had. Around 2 years has been my max before, and around that 2 year mark I've had duct tape on the cord to hang on a little longer. If I can update in a year, I'll try to do so.

Been using these for two years and they've held up well. I use a variety of headphones and earbuds throughout the week and these have the best fit of any of my earbuds and are the most comfortable to wear for extends periods. As in-ear-monitors I use them for electric guitar (with a cord extension), and they provide a little more tonal quality than entry-level closed-back headphones. I have found myself using them for general music listening around the house when wireless isn't a requirement or I'm tired of wearing over-ear headphones. For the price and their durability they're a great value just to have in a backup bag and I keep these on the table next to my monitors and practice amp.

I recently picked up the YINYOO Easy KZ ZST in-ear earphones, and I must say, these budget-friendly earphones have exceeded my expectations in terms of sound quality and overall value. The sound signature of these earphones is impressive, with a combination of hybrid balanced armature and dynamic drivers. It provides a balanced and crisp audio experience with clear highs, detailed mids, and a satisfying low-end. These earphones handle a variety of genres with ease, making them versatile for all sorts of music lovers. I found myself enjoying everything from acoustic melodies to heavy rock without any disappointment in sound quality. The design of the YINYOO Easy KZ ZST is also a plus. They are lightweight and comfortable for extended listening sessions, and the colorful design adds a touch of personality. The fit is snug and secure, ensuring that they don't fall out during activities or workouts. Another great feature is the detachable cable, which is a rare find in earphones at this price point. This feature not only allows for customization but also makes it easier to replace a damaged cable without having to replace the entire set of earphones. However, there are some areas where the YINYOO Easy KZ ZST could be improved. The included ear tips could be of better quality and provide a more secure fit for different ear shapes. Additionally, while the sound quality is generally great, it may not satisfy audiophiles seeking the utmost in sound precision. In summary, the YINYOO Easy KZ ZST in-ear earphones offer a fantastic listening experience for the price. The sound quality is excellent for the budget, and the detachable cable is a thoughtful addition. While there's room for improvement in terms of ear tip quality and fit, these earphones represent a solid value for those who appreciate good sound quality without breaking the bank. If you're looking for a budget-friendly option that punches above its weight, the YINYOO Easy KZ ZST is worth considering.

When I bought these in '18 I was merely looking for a pair of headphones that were inexpensive. I had no idea what IEMs were. My frame of references were: the OEMs that came with iPhones I had before and the Samsung AKGs that I traded up to later, and a handful of other budget headphones and wired earbuds from various companies. For $20 these outperformed anything I've owned up to that point. As if it took all the great bass, mid, and treble elements from every headphone/earbud I liked, removed all the elements I disliked, and put them into this thing. I couldn't believe it. How did these earbuds sound better and cost less than all the sound pieces I've bought before? Who the heck is KZ? I would later come to find out that this very IEM would become the starting line of the great budget IEM race. Fast forward 6 years. Tozo, Soundpeats, Anker, Moondrop, 7Hz, Dunu, etc. have saturated the IEM market with their offerings with a range of prices to compete with and even outperform tech giants. You know the ones. Some even have endorsements and collaborations from audiophile YouTubers. Even with all of these new products and the innovations made since this product came into the market, the KZ ZST still holds it's own as a go-to option. With 14K reviews and counting, The KZ ZST has become the template and baseline for all other IEMs to follow. That said, downsides: Cables: The fact it has cables is a con in this day and age. It wasn't an issue 5-6 years ago because smartphones still had headphone jacks. The cables went kaput after 2 years of everyday use. I thankfully bought upgraded IEM cables just in case and are what's attached to the ZSTs now. I haven't used the ZST after I got other IEMs and wireless earbuds in 2021 but I tested the ZST recently. It still works and sounds better. Build: The earbuds casings broke at the seams when I replaced the broken cables. They did snap back together and held together when retested them. For $20 it's not a big issue. Features: It plays sounds...and that's about it. No active noise cancelling. It's wired so tangles are a thing. Sound: I repeat this is subjective. Your own mileage will vary. Volume: Great. Plenty loud. It has drivers and that helps in out in that department. Bass: Great. It's not terribly aggressive and I prefer it that way. Mids: Clear vocals and instruments. Treble: Bright. Can get sibilant in some ranges. I maintain a score of 5 after six years of ownership. If you have a need for a wired $20 IEM that has stood the test of time, then these are still a good pick among MANY options.

KZ ZST: The Colorful King of Budget HiFi If you are looking for audio performance that punches dramatically above its weight class, stop searching. The KZ ZST Colorful Hybrid In-Ear Earphone is a legitimate marvel that has completely redefined what listeners can expect from a budget-friendly pair of wired earbuds. I am absolutely thrilled with this set—they simply work great and deliver an incredibly rich listening experience, whether I’m gaming, streaming, or just enjoying my music collection. Hybrid Power for Detail-Rich Audio The secret to the ZST’s success lies in its sophisticated Hybrid Driver configuration: 1 Balanced Armature (BA) and 1 Dynamic Driver (DD) in each earpiece. This is technology usually reserved for headphones costing several times more. The result is a vibrant, "V-shaped" sound signature that is immediately engaging: • Dynamic Driver (DD): Handles the low frequencies, delivering a deep, satisfying bass that has punch and presence without becoming muddy. • Balanced Armature (BA): Handles the mids and highs, providing exceptional clarity and detail in vocals and treble. The combination ensures that no part of the sound spectrum is left behind. The music feels lively and energetic, offering an immersive soundstage that makes these a perfect set of Wired Earbuds for everything from orchestral scores to intense electronic music. Ergonomics and Durability The headphones boast a striking, high-end look thanks to their Colorful semi-transparent shell, which offers a peek at the sophisticated hybrid drivers inside. But the design is more than just aesthetics; it's highly ergonomic. The contoured shape, often called a custom-monitor style, is designed to fit snugly and comfortably over the ear, making them fantastic In-Ear Monitors (IEMs) for prolonged use. For me, this comfortable, locked-in fit is critical. Whether I'm moving around or settling in for a long gaming session, the secure fit provides excellent passive noise cancelling—allowing me to focus entirely on the audio. The detachable cable is another massive plus, ensuring easy replacement should the cable ever wear out, extending the life of these fantastic drivers significantly. The Best Value in Audio The bottom line is that the KZ ZST delivers an astonishing level of HiFi Headset quality without the audiophile price tag. They handle complex mixes and fast transients with ease, providing a level of instrument separation and detail that truly makes a difference. They're a plug-and-play solution that just works great right out of the box, making them the ultimate entry point into the world of quality IEMs. If you are a musician on a budget, a commuter who values sound quality, or a gamer seeking clear audio separation, I cannot recommend the KZ ZST enough. They prove that exceptional audio performance doesn't have to break the bank.

I can't believe how good these sound and how comfortable they are. There's a reason they have so many positive reviews. These sound better than any headphone I've owned and they were only $18! I'm so glad I didn't spend more than I needed on a different pair. These do the trick and the price was more than right. I did crank the bass in Poweramp to make them sound a little better to my ears. The build quality is top notch and there's nothing about these that feels cheap. I'm beyond happy with my purchase and would recommend these to anyone.

The sound quality of these are just as good as my previous gaming headset, and are comfortable and a perfect fit for my ears! The cord is not too long but provides enough slack for movement. I can also tell that they will be perfect for travelling.

I was skeptical of these style of head phones because of their average low price range, but they definitely caught my attention and want to give them a try. Every posting tend to have lots of random abbreviations and unfamiliar terms so I just went with a random one. The first thing I noticed when I began unboxing them was the cheap feeling, which was expected for the price. The cord was very short for what I prefer, running a about 3 ft. The cord length is not described in the product description I believe, which should have been a red flag from the start. Now the most important part, the sound. The ear buds created a surprisingly impressive sound. It was actually one of the most crisp sounding earbud style headphones I have heard, which was actually the main description I had heard about these style headphones. It just seemed very natural like all the highs and lows blended so well. I feel like if you could take away the feeling of them physically being in your ears, you wouldnt know you're hearing earbuds. It sounds great, but not to a point of ahhh. I want that natural sound, but with that deep, heavy sound too. The ability to hit those strong lows really well and be able to keep up. I was expecting the earbuds to sit in your ear very nice and comfortable compared to most other earbuds, given the design looking very ergonomic. They are designed to sit right in your ear like a mold and provide extra comfort, but I found it difficult to keep in my ear. I think the low quality had a large effect on that issue, like how the cord came out of the earbuds at an awkward part for it having to run a loop over and down the back of my ear. The positioning of where the cord came out interfered with how it rested in my ear. When I unboxed the earbuds I had to connect the cords to the buds which was one of the more interesting concepts of these style earbuds. The cheap feel of both the cord and buds did not give me confidence in conducting this task. The connectors that plugged into the buds had to small prongs that looked like a single bump would break them clean off. Once I had the cords fully connected I tested to see how difficult the removal of the cord would be and it was fairly easy. I wanted to test this because one of my favorite features of these earbuds, is the fact that you can disconnect the cord and change it out with a different length or a different type of connector. That is super convienent for people that may want to play video games with these but require a long cord. Then they want to use them for listening to music on their phone, but they don't want to have a super long cord connected to their phone, or they might need a different connector.

Easy fit , perfect sound Just use peace software and know the equalise band

I've worked my way few a few pairs of IEMs on Amazon & returned them all.... But these are really good for the price & I shall be keeping them. Good mix of bass & high end responses. You might want to upgrade the cable though....

Ottime cuffie in-ear. Prese per provare come tenessero quindi sclete anche per il costo. Devo dire che tengono perfettamente sulle orecchie e il suono o molto buono. L'unica pecca per me sono i fili audio non bianchi ma marroncini eun filino troppo corti ma va bene così. Consigliate.

Très bonne qualité, j’utilise un jeu et pour écouter ma musique je recommande

One side doesn't work. Can i request the refund
