Coming to the physical aspect of the earphone, it has got that classic KZ shell design. The faceplate on the earphone is aluminum, so that you can expect excellent durability. And it has got transparent acrylic shells.

As for the looks, they are pretty modern and stylish in looks. It has got that futuristic vibe with the V-shape design. They look rather premium with a clean finish on the earpieces. You can also get three color choices on the shells: black, purple, and cyan.

Something you may find problematic about this earphone is the size. Although, if you have large ears, you won't have anything to worry about. But people with smaller ears will find it challenging to fit in their ears or won't find proper comfort with these on.

KZ ZSX Features and ratings

If you are still wondering and not sure about the earphones, you should check out the features and ratings. This will give you the complete picture of these earphones, and you can make a properly informed decision. So, let's go through the different features and see how I rated them out of 5.

Sound quality 

You will get more than you expect from these earphones in sound quality right off the bat. Whether it's the bass or the clarity or you are after the tone, this satisfies in every way. There is nothing to nitpick on this one in terms of sound quality.

The bass you get here is utterly impressive. It doesn't have that sluggishness and offers an excellent pace to match the energy. For the mid, you get a neutral quality, which gets a slight boost in the upper portion.

Finishing off with the treble or clarity, you can't have any complaints with the earphone. It's crisp and clean, but it doesn't start bleeding your ears. The details in the treble are just exceptionally good. Altogether, it's a complete and satisfying package for the sound quality.

Rating: 5/5


Combined with that fantastic sound quality comes the tremendous performance of this earphone. It has a broader soundstage on the earphone, providing the depth you can always admire. You can get the whole idea of the soundstage from the sound separation of this earphone.

When you add in the noise isolation factor to that, you just get into another realm of music with this one. Even with the noisiest crowd around you, there will be no issue with the music you listen to through this earphone. Overall, the whole thing just works out perfectly for music.

Rating: 4.5/5

Comfort and fit 

Now, this is dependent on the user. People with larger ears will have no discomfort or issues with the fit. But people who have smaller ears may find it difficult to fit, which then leads to discomfort of some sort.

Sure, it doesn't have any extra measures for comfort, but the design supports it. It has got that futuristic vibe with some thoughts behind it. So, you can expect a good level of comfort if you somewhat decent ear size.

Rating: 4/5

Looks and build 

In terms of looks, there is nothing to question on this one. It comes with a stylish and modern appearance that gives you a sense of a new generation. It looks cool when you put them in your ears.

While the looks are impressive, it doesn't lack the build quality either. The aluminum faceplate gives it that sturdy exterior that protects the whole thing from rough and heavy usage.

Since it's an IEM, you can expect pretty hardy earphone usage. And a lot of that is possible because of the high-quality cable of the earphone. It's just thoroughly impressive. While it may tangle a bit, it doesn't break or tear easily.

Rating: 4.5/5

Value for money 

Without a doubt, this one has to be one of the best value-for-money in-ear monitors or even earphones in general. The price you pay for the earphone is nowhere near the kind of quality you get out of this.

Everything about the earphone exceeds expectations, considering the affordable price tag. This sole reason can be enough to go for this one without any second thoughts at all.

Rating: 5/5

KZ ZSX alternatives

Are you not working out for you? In that case, you can check out some alternatives to this one. Here are some similar earphones you can go through a little.

  • Shozy Form 1.1

In terms of performance and sound quality, this is pretty close to the KZ ZSX. While the bass on this one is a bit better, the mid and highs are a little better on the ZSX. But the difference between both the earphones isn't that noticeable.

  • TIN HiFi T2

When it comes to budget choices, this one is a great competitor to the KZ ZSX. The sounds on this one are detailed and clean. The bass on the ZSX is comparatively better and deeper than the Tin HiFi T2. But the tonal quality of the Tin HiFi T2 is much smoother and sounds much more natural.

As you can see, both the earphones here can go head-to-head with the KZ ZSX. It all comes down to which features or factors matter to you more.


To sum up, KZ ZSX is an excellent earphone that you should indeed consider if you are looking for something within a budget. It will exceed your expectations, and you won't be disappointed with the performance. The sound quality, build quality and looks work out perfectly for the price.

It's an excellent choice for people getting into audio engineering as well. It's within budget and works well for editing music and mixing them.
