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.

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.

This is the best way I have heard music up to this point. Part of that might also be I got my first budget mp3 player/DAP (hiby r1) to go with these. I'm not an audiophile, but I can tell the vast difference in sound quality between your average 5$ earbuds and these. I usually listen to music out loud because I don't like the experience of earbuds or headphones, but I have been converted! I love these things and it makes listening to music on the go way better. Totally worth the money. These deliver on what they say, functioning exactly as advertised, and are very comfortable. The only slight downside is the fit, the over the ear loop slips forward or sideways easily. But I prefer that situation over if it was uncomfortable.

High quality is where you find it.n These are the best wired earbuds I've ever heard. An audiophile's dream (especially in this price range!): the frequency response (20,000hz - 40,000hz) is spectacular and absolutely SPARKLES in the high-end, and the low-end bass is powerful and accurate, never overwhelming. Functionality, compatibility, cord length/connectivity and the build quality are all A+. Oh yeah, and last but not least: they are as pretty to look at as they are to listen to (I selected the purple/blue) I'm beyond satisfied with this stellar purchase!

It is two in the morning, and I find myself writing a review for these headphones. These might not be someone else’s cup of tea, but they made this juice and I am addicted. This is my initial review since, i just got them yesterday. I have read that the material of the wire is not the best. That it does not have bass or the highs are too bright. I took them out of the box and immediately I fell in love when I plugged them in. The music just came alive. I am hearing things I did not before. The bass balance through me right back into what some pretty good full range floorstanding Greg Timbers created JBL studio 590’s speakers sound like. If you are thinking of pulling the trigger on these headphone. Do it!! I am not a musician, but I love music. I have not stopped listening. The sound is just something else. The dual driver really does make a difference. If this is musicians little secret then, now I know what the masses felt like when Algebra was introduced to them. It sounds like I’m hyping them up, but you got to give props where it is due. The highs are not fatiguing. I have used headphones where I needed to rest my head. Bass was lacking or at some point would distort, not the case here. Here is what I am using to make these headphones sound great: I have an IPhone 6s and with good reason. The audio port for this model was made better than some D A C currently out. It is Audiophile quality. Yeah, who knew?This info based on Ken Rockwell site. Yes I know some will say it is not reel to reel or vinyl. Like i said might not be your cup of tea. Still what you have might be better. What I have not encountered with these is the pressure that is created in your ear. The kind that makes the driver in the headphone pop and crackle. The noise cancelling is passive and not active, but it works. It is significantly reduced. The distortion is not present, unless it is on purpose. I have tried to turn it up to see the point that I do, but I turn it down cause I do want to hear for the next few years. The bass is punchy, and at times sounds bass heavy. Of course this is dependent on the source material. I have tried it on material that gives presence in the imaging. Like 3D music is great. Imaging is just something else. OK, I know some one is going to ask this, maybe to themselves but it will be asked. What about movies? I tried gravity. The entire scenes before they get hit by space debris is something else. It is where you can really appreciate the imaging. Hearing Sandra Bullock speak through her mic in the space suit.OMG. You can hear just so much detail. Even doing some critical listening you hear things you normally don’t. Like store bought bread and bread made in a bread machine. Like that. This is a gem, for those who like music or movies. Based on the sound you are expecting the gut punch. Instead your skull is being blown by every track sampled. For the price you wont be disappointed. UPDATE: these headphone are playing strong as the first day out of the box. For those who do research on what they buy. Do yourself a favor read the review of Docholliday review. This reviewer has gone the extra mile to the detail of what you hear into some words, frankly that’s hard to do. Just know if you have not bought these yet you are for sure missing out. These IEM’s are a great buy for the price. Fall in love again with your music.

These plugged into my phone with no drama, and the sound hit way harder than I expected for something this cheap. The bass has some punch without getting muddy, and the highs stay clear enough that voices and details come through clean. They sit comfortably in the ear, so I can wear them for a while without feeling like my ears are filing HR complaints. The cable feels sturdier than the usual budget earbuds, and the inline controls actually respond when you press them. The mic is decent for calls and does not make you sound like you are trapped in a cereal box. For everyday listening, gym use, or random Zoom calls, they hold their own without trying too hard.

I'm a drummer and they still work perfectly, with a great sound! I'm thinking on purchasing the Bluetooth engagement to use them with my phone.

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.
