    For this price, it''s a prize!
    I can talk about the flaws but for this price it's only a win! Make sure you do a proper burn-in time of 50 hours. And always double check the right ear-tips for yourself. It has to seal perfectly your ears for taking full potential of the IEM. Some standard rules: Foam-tips: for IEM's with Balanced Armatures (Foam resolves/suppress highs better). Silicone-tips: for Dynamic Drivers (Silicone gives better highs). + Bass and Mid-centric sound. + For bass players and singers. + Soundstage is wide. + Natural sounding (Good for acoustic music). + Good sub-bass. + Warm-ish and a tad dark-ish sound signature. + Good isolation. + Detachable cable (Crazy for this price). Grap yourself an upgrade cable. + Perfect ear-fit... if quality control (QC) does work. In perspective of my other budget IEM's: + KZ ZS3 (For bass players and singers and a nice replacer for Shure SE215). + KZ ZS5 v1 (For balanced and crazy micro details). + KZ ATE (For 100% bass heads). + Xiaomi Hybrid Pro 3 drivers ( For quality on the move moments). + SOMiC V4 (Like KZ ZS3 with lack of sub-bass but without bass bloat). + Rock Zircon (Just fun IEM but missing details).
    - Bloated mid-to-high bass, therefore tinny sounding. - Shallow highs. - No new star-silicone tips included. - Old horrible cable with lots of microphonics. - QC issue: Shelf housing not aligned properly, causing cutting sharp edges (Putting tape soles the problem).

    high value
    The Knowledge Zenith ZS3 earphones are another nice addition to the KZ line-up, and out of the recent (2016) models by KZ, these seem to be the most recommended of the bunch. Although they offer decent technical performance, the bigger reason I like these is their look, musicality and price! Sound: Very smooth high end; warm, forward and pleasing mids... Vocals are vivid and aren't pushed to the back, and have a lot of energy and are natural(Toss on a vocal-oriented track to hear the most of this) Bass reproduction on the ZS3 will provide a very satisfying sound to compliment the low end in your music. All of these factors will work together to create a warm, surrounding, 'comfortable' sound that will stick out as soon as you put them on! Guitars have texture to them and aren't complete static. You can pick out the different instruments with your hearing and to an extent you can hear the ring, crackle, crunch or pluck of guitars. The ZS3s kept up with bass petals fairly nice and bass guitars have a powerful impact. I recommend them for genres like Rock(very much), Funk, Alternative, Hip Hop(definitely), Rap, Electronic(can only vouch old stuff, sorry) and I'm sure they'll work fine with many others. Vocal oriented music is very much worth a try on these!
    -Thrash music tends to lose focus at times. It does not perform the same as Rock music the way I described it in the Pros -The sockets on the earphones where the double-pinned connectors go into are quite delicate and could break if the two connectors are jolted around, leaving the earphone busted. Do not crush them or squish them up and they should be OK... -It was difficult for me to get a correct seal with these earphones. Each time I'd insert them, they would seal too much and create a vacuum effect, which was uncomfortable and I can't hear the music that way. Fiddling around with them, I manage to get a correct seal, but it takes too much practice. The memory wire under the earphones could be the culprit, as I seem to get good seals when it is pushed out of the way. -Nozzles are stubby and straight. There's not much for the tips to grip on to. Sometimes one of the silicone tips will slip off when I take the earphones out of my ears. -Bassheads may be disappointed by the controlled bass...

    One of the best earphones for more than the best quality!
    Ohh how should I describe them shortly.. There are so many amazing things about these earphones. The quality, the price, the durability, the sound, the fit.. Everything is so perfect to these monsters. First of all, I'm very experienced in earphones and quality sounds as I am a musician and drummer. I used to have some JBL earphones for some time until they broke so I needed to replace them with other ones same quality but this time I needed something different for my ears. Believe it or not, I spent 6 hours searching the best quality earphones in the best price, I was and I am very picky and I demand a lot to something I buy. Anyway guys, these earphones are just too good for the price and contrary to some other over 70$ earphones, these ones for 10-20$ have the same sound quality with very slightly lower quality to some features. However, these are 20$ and have the sound of over 70$ earphones, trust me on that. I'm very very pleased by their sound and their isolation.
    The sponge inside of the left earphone got detached once I changed an eartip, not a very big deal tho since I just pushed it in and now its fine.

    Well build earphones. Soundstage is ok , high freq ok , but there would be a little bit more bass. Lack of bass in my opinion lead to a little loss of the quality . The naturality of the sound is decreased. But you get what for you pay. In general high quality earphones which you can get for a very low price !!! They can be used during sport activities - they have bending earhooks. Wygodne słuchawki z mikrofonem . Można ich używać w trakcie aktywności sportowych - mają giętkie mocowania kabla. co do jakości to szczerze mówiąc spodziewałem się czegoś lepszego. Generalnie tony wysokie są ok ,środek także. Brakuje mi naturalnego basu . Co daje trochę nienaturalny efekt przy słuchaniu. Generalnie warte są wydanych pieniędzy - chociaż mogłoby być lepiej.

    very good fit and sound
    Came in 6 weeks but problably due to summer?? The packaging was perfect and the box looks like a retail product. The earphones looks exactly like advertised on gearbest. It was easy to set up since each cable has a marking 'R' and 'L'. When connecting the letter should be facing out. The sound is clear and there is no fault to be found. The only reason i had not left 5 stars is because i found another KZ earphones with dual drivers were more warm, acoustic sounding. I wanted to try this because of removable wire in case in need of replacing or adding bluetooth module. Overall still great price for the quality. Tried to add video but requirements of gearbest too complicated and will not accept the video at

    Extremely Bang for the Buck!
    Vocals are nice and smooth, I sometimes find it lacking for some tracks but still well within my preference. Mids are excellent but easily gets overwhelmed by the boominess of the bass. Bass is amazing, extends to the point where it shows you how big its soundstage is. Soundstage is where I fell inlove with it, you can really hear the space between the instruments and makes you feel you're in a room with properly setup'ed speakers. I have not heard any in ears with this big of a soundstage at this price ever. I usually run to my m50's whenever I need music therapy but this changes everything. Comfort is A+, when I first fitted it without the wires, it just went thru my ears like it was custom molded. I can wear this for hours without fatigue or even to sleep.
    Memory wire needs a little getting used to. Bass can be to overwhelming and uncontrolled. Mids gets muddy because of the bass. (Music dependent)

    A good IEM with an awful stock cable
    - Pleasantly bassy (less than ZS1/2, though) - Typical KZ quality sound - Very comfortable fit (with "modded" cable - see cons below) They may sound a bit too energetic, too punchy for me. Perhaps I prefer a 'darker' sound signature, here the mids and the highs are more forward, sometimes creating fatigue when listening for longer periods. Happens only on certain records, so it may just be the ZS3 revealing poor recordings. Or it may just be an issue with my preferred sound. In any case, make no mistake, the ZS3 is a QUALITY headphone. For the price, it's actually amazing and I really like it.
    - Cable. - Cable. - Cable. The cable has an actual piece of wire around the "ear area". You're supposed to mold it around the ear for a better fit. But a wire being a wire, it remained stiff, pushed against my head with the slightest move, breaking the seal within seconds. It was so bad it rendered the IEM unusable. Then I ripped the wire out (use tools, I used my bare hands out of frustration), and "wireless", the cable is a perfect fit and the IEM stays always in place.

    One more great order of great product at gearbest
    The product is good, not excellent. But for the price you pay it's great. I recommend doing burn in to improve the quality of the earphone. When it arrives raw, you are amazed at a supposedly low quality, but then it will improve as you use or burn in to speed up the process. You need to assemble for first use and have "sponges" of different sizes for different ear holes. Then allows adjustments to your ear. The adjusting tab on the ear is malleable and also allows you to adjust to fit firmly into your specific ear shape.
    Need to burn in to accelerate the improvement of the earphone or much time to use to improve its quality. When it arrives the audio quality is not very good.

    Real basshead headphones
    One of the most powerful components of these headphones - bass. Starting from 50Hz it tight, fast, massive - ideal for electronic dance music. Mid marked as good, but about high ... They do exist, but not soft, no air. The scene is quite small, the panorama is not felt, but they do not expect it and, worse, they do not get from this. Also worth noting is the design and usability of the socks - the cord can be replaced in case of breakage of the plug (which often happens), ergonomic shape is very good - in the ear sits firmly and does not think to fall out even during vigorous activity.
    You must correctly fit the headphones in your ears, or sound not get proper.

    audífonos kz zs3, buenos y baratos.
    Recibí estos audífonos en 18 días, son tal cual eran en los videos de review, un poco complicado al inicio, si no estas acostumbrado a este tipo de audífono. buen sonido, buena calidad, el cable nomas que se nota pegagoso. Los tengo un par de días y hasta ahora estoy contento con la elección. Con otros audífonos, usaba el volumen en un 60% a 70%, con estos con las justas al 30%, eso se traduce en un ahorro de batería, gracias a que cancelan buena parte del ruido exterior. En fín, estoy animado en conseguir otro modelo de esta marca, un poco mas pro. No puedo decir mucho de la calidad del sonido, pero son mejores que lo últimos que he tenido y satisfacen mis expectativas,
