The KZ ZS10 are decent mixed usage wired in-ears that look great and sound above-average with most tracks. They have a cool design that showcases the electronics inside the buds. The buds are also angled to better fit the contours of your ears and have a detachable audio cable, which makes them a bit more durable overall. Unfortunately, they are a little bulky, so they won't be as comfortable for all listeners. They also do not have a mic or in-line controls, although you can purchase a variant with both.
The KZ ZS10 are a decently well designed and great looking pair of wired in-ears. They have angled earbuds shaped to fit within the contours of your ears and come with a couple of tip sizes to help you find the right fit. This makes them a bit more comfortable than average in-ears, but unfortunately, the buds are a little bulky, so they may not be as comfortable for listeners with smaller ears. On the upside, they have a stable fit for the gym, they're compact enough to carry on your person at all times, and they have a sturdy build quality with a detachable and replaceable cable, which makes them a lot more durable. They do not provide an additional cable in the box, which is slightly disappointing, but for their price range, their build quality is very good.
The KZ ZS10 have a stylish-looking design that feels a lot more premium than their price range would suggest. They have slightly bulky, but angled earbuds that fit a little better than most typical in-ears. The buds also have transparent casings that showcase the electronics and looks great, especially with the red highlights of the PCB ( printed circuit board). The braided cable also adds to their high-end appeal, which puts them on par (look-wise) with much pricier in-ears.
The KZ ZS10 have a decently comfortable in-ear fit. They come with a couple of tip sizes to help you find the right fit. They also have an angled design to better fit the contours of your ears. Unfortunately, their earbud design is rather bulky which may not fit as well in the ears of every listener. This makes them slightly less comfortable than some of the other angled design like the Shure SE215 or the Westone W40 but still a bit better than typical in-ears.
These headphones do not have a control scheme and do not come with an extra cable with an in-line remote. On the upside, you can get a version of the KZ ZS10 with an in-line mic and remote, but it only has one multi-function button and no volume controls.
These headphones, like most in-ear models, are very breathable and will not make you sweat more than usual even during more strenuous activities. The earbuds are a little larger than your average in-ear design so they will trap a bit more heat within the notch of your ear but it's not a very noticeable temperature increase. They will be breathable enough for most casual activities and for running and working out.
Like most in-ears, the KZ ZS10 are very portable headphones. They will easily fit into your pockets and aren't much of a hassle to carry on you at all times. Unfortunately, they do not come with a case which is slightly disappointing.
The KZ ZS10, have a good build quality and come with a replaceable cable. The earbuds are decently dense with a see-through casing that looks great and should be durable enough to handle multiple drops without cracking. The cables are also braided and durable enough for most conditions, although they are not as thick as some similarly designed in-ears like the Shure SE425. On the upside, you can replace the cable if it gets damaged, which makes them a lot more durable than typical in-ears, but unfortunately, they do not include an extra cable in the box like the Mee Audio M6 Pro or the Westone W40.
The KZ ZS10 are stable, wired in-ear headphones. They have a pseudo-ear-hook design that's flexible doesn't have real rubber or plastic hooks but has a slight coating on the parts of the cables that attach to the earbuds, that you can wear behind your ears. It's not as stiff as the other ear-hook models like the Anker SoundBuds Curve, but they're still stable enough for most sports and exercises and will rarely fall out of your ears unless you physically pull them out or the audio cable gets hooked by something.
The KZ ZS10 is a decent sounding pair of closed-back in-ear headphones. They have a deep, powerful and consistent bass, an even and decently balanced mid-range and a good treble. However, their bass is a bit boomy and muddy, their mid-range sounds a bit recessed and hollow on vocals and lead instruments, and the treble is a little on the bright side. Also, they are a bit inconsistent with sibilances (S and T sounds), and like most other in-ear headphones, don't have a large and speaker-like soundstage.
The bass is great. LFE (low-frequency extension) is at 12Hz, which is great, but low-bass is lacking by about 2dB. This means that the KZ ZS10 lack a little bit of thump and rumble compared to our target, but this won't be noticeable to most people. Mid-bass, responsible for the body of bass guitars and the punch of kick drums is flat and well-balanced. However, high-bass, responsible for warmth is overemphasized by more than 3dB, making the bass of these headphones a bit boomy and muddy.
The mid-range is very good. The overall response is quite even and decently balanced. However, the broad 5dB recess centered around 700Hz pushes vocals and lead instruments towards the back of the mix by giving more emphasis to the bass and treble frequencies.
The treble performance of the KZ ZS10 is good. Low-treble is over our neutral target by more than 2.5dB, bringing a bit of excess intensity and brightness to the vocals and lead instruments. Mid-treble is a bit underemphasized and rather uneven, which makes the reproduction of sibilances (S and T sounds) a bit inconsistent.
The frequency response consistency is excellent. If the user is able to achieve a proper fit and an air-tight seal using the assortment of tips that come with the headphones, then they should be able to get consistent bass and treble delivery every time they use the headphones.
The stereo imaging of the KZ ZS10 is great. Their weighted group delay is at 0.14, which is among the lowest we have measured. The group delay graph also shows that the entire response is well below our audibility threshold. This ensures a tight bass and a transparent treble reproduction. Also, the L/R drivers of our test unit were very well-matched in frequency, amplitude, and phase response. This is important for accurate placement and localization of objects, such as footsteps and instruments, in the stereo field.
The soundstage of the KZ ZS10 is poor. This is because creating an out-of-head and speaker-like soundstage is largely dependent on activating the resonances of the pinna (outer ear). The design of in-ears and earbuds is in such a way that fully bypasses the pinna and doesn't interact with it. Also, because these headphones have a closed-back enclosure, their soundstage won't be perceived to be as open as that of open-back earbuds like the Apple AirPods, Google Pixel Buds or the Bose SoundSport Free.
The harmonic distortion performance is very good. The amount of THD produced is very low throughout the range, especially in the bass range. There is a bump in the THD of the mid-range, but it's still within good limits. Also, at 100dB SPL there is a decrease in THD in low-mid, which is probably due to the increased flexibility of the driver under heavier loads.
The KZ ZS10 provide enough passive isolation with their in-ear fit to be suitable for most environments. However, since they are not noise-canceling headphones, they will not do as well against low-frequency sounds like that of a rumbling engine. Also since the buds are a bit bulky, it can be sometimes difficult to achieve the right airtight fit that will prevent more ambient noise from seeping into your audio. On the upside, being in-ears, they do not leak much so you can play your music at much higher volumes than average and mask some of the ambient noise without distracting the people around you.
The isolation performance of the KZ ZS10 is decent. In the bass range, where the rumble of airplane and bus engines sits, they achieved about 2 of isolation which is inadequate. In the mid-range, important for blocking out speech, they reduce outside noise by more than 17dB, which is good. In the treble range, occupied by sharp S and T sounds, they isolate by more than 32dB, which is quite good.
The leakage performance of the ZS10 is great. These in-ears do not leak in the bass and mid ranges, and their leakage is concentrated in the treble range. Therefore, their leakage will be thin and sharp sounding. The overall level of the leakage is quiet too. With the music at 100dB SPL, the leakage at 1 foot away averages at 29dB SPL and peaks at 51dB SPL, which is about the same as the noise floor of an average office.
The KZ ZS10 do not have a microphone and therefore, the recording quality has not been tested.

The KZ ZS10 are a wired headphone with no in-line remote, Bluetooth or base/dock. They have a wired 1/8" TRS connector but unfortunately, the version we've tested does not have an in-line remote or mic, so they will not have voice support with console controllers. On the upside, they have practically no latency when watching movies and videos, like most wired headphones.
These headphones are wired and do not have a Bluetooth connection. If you want a good Bluetooth in-ear for more casual use, check out the BeatsX.
The KZ ZS10 have a simple 1/8" TRS audio cable with no in-line remote or mic so they will only provide audio when connected to your phone, PC or console controllers. However, you can purchase a version with a limited control scheme and mic that should work with your console controllers.
These headphones do not have a dock. If you need a headphone with a dock that also has a wired connection for gaming or watching movies, then consider the SteelSeries Arctis 7. However, they will not have the portability of the KZ ZS10.
These are passive headphones that do not have a wireless range since they're wired. If you want a good wireless headphone for critical listening, consider the Bose SoundSport Wireless.
The KZ ZS10 have a simple wired connection with practically no latency. Unfortunately, this also means that they're limited by the range of the provided cables.
The KZ ZS10 are a great looking pair of wired in-ears with a decent enough performance for most use cases. They're lightweight and very portable so you can have them on you at all times. They also have a stable in-ear fit with a pseudo ear hook design that will prevent them from falling out of your ears even during more strenuous exercises. They're a bit more comfortable than typical in-ear, however, since the earbuds are somewhat bulky, they may not be the ideal choice for all listeners especially those with smaller ears. On the upside, they're one of the best sounding earbuds; they deliver a satisfying sound quality and a decent noise isolation performance that makes them versatile enough for most use cases and even better than some of the pricier in-ears compared below. See our recommendations for the best budget earbuds.
The KZ AS10 and the KZ ZS10 are very similar headphones. The ZS10s’ sound is more accurate while the AS10 has more bass, a bit more punch to it. Design-wise, they are nearly identical. Both have bulky angled earbuds; the only difference being the AS10 are a bit thinner, maybe making them a bit more suitable for everyone and more comfortable for smaller ears. The AS10 also have better passive noise isolation.
The 1More Triple Driver are on par, if slightly better than the KZ ZS10 thanks to the in-line remote. The 1More have a slightly better balanced audio reproduction than the KZ. They also come with a great in-line remote and has volume controls unlike the mic version of the KZ (which should be a bit more versatile than the variant we reviewed). The KZs on the other hand, have a more durable build quality, thanks to the replaceable cable. They also look a little more premium thanks to the transparent casings for the earbuds and the braided audio cable.
The KZ ZS-10 are a better sounding critical listening in-ear than the Shure SE215. The ZS10 have a slightly more premium-looking design and a better-balanced sound. The SE215 on the other hand, have a slightly more comfortable fit and better noise isolation than the KZ. However, both headphones are well-built in-ears, with no in-line remotes but the better sound quality of the KZ makes them the better option, especially since they are a lot cheaper than the SE215.
The Sennheiser Momentum In-Ear are a slightly better and more versatile option than the KZ ZS-10 with no mic. The KZ have a better sound quality, they're more comfortable and they're a lot more durable thanks to the good build quality and replaceable cable. The HD1 In-Ear however, have an in-line remote, which provides control for iOS devices and has a microphone for taking calls, making them more versatile for everyday casual use. They also come with a case, have a slightly more compact design than the KZ ZS10. On the upside, if you get the mic variant of the KZ, they would be the better headset overall.
The Bose Soundtrue Ultra In-ear are a slightly better headphone overall than the KZ ZS-10. The Bose have a more comfortable earbud fit, which most will prefer over the in-ear design of the ZS10. They also have an in-line remote and a mic so you can more easily use them with your phone, and they're more convenient when gaming. On the other hand, the KZ ZS10 are better built, with a replaceable cable. They also have a variant with a mic that should perform a little better than the Bose. The ZS10 also look a lot more premium than the SoundSport Ultra In-Ears, especially for their price.
The KZ ZS-10 are slightly better critical listening than the Etymotic HF5. They have a more comfortable fit despite their larger than average earbuds. The KZs also have a better-balanced sound quality with a stronger bass, a better mid-range and a more balanced treble. They also have a more durable and eye-catching design with a detachable audio cable. On the other hand, the Etymotic isolate passively a lot better than the KZs. They're also more portable and come with a case and more accessories than the ZS-10.
