The Packaging Build & Design Sound Quality
Summary & After Verdict



Even before making the purchase, I have already heard a couple of good things about KZ. The fact that they have been around for a while goes to show something good about their products… But I need to say this – The earphones are pretty good, but the packaging is underwhelming.



The first impression I got after tearing this out of the envelope – Why!? Just why does everyone want to copy Apple’s packaging style? There are so many people and designers in China, can’t anyone come up with their own original design ideas?

But I won’t lie though, the presentation inside of the box caught me a little off guard – It is clean and actually looks pretty cool.




The small package comes with all the essentials:

  • Earphones.
  • 3.5 mm cable (with a microphone attached).
  • Ear caps – Small, medium, large.
  • Instruction book.
  • Warranty card.
  • The carrying case is not in the box but came in the envelope itself.

Nothing to complain about, someone has learned and adapted well from the Japanese company – A complete package is very important to value add and wow your customers.



Putting the disappointing “Apple-inspired” packaging aside, I would say that ZSN Pro has some good and solid build quality… But again, the design really needs some serious work.



Well, it’s a braided brown cable with “rectangular black Minecraft blocks”. Not that it’s bad, and the braided cable is in fact very durable. It’s just that some people may like the so-called “industrial” or “vintage steampunk” look, but my personal preference is – Dirty brown? Yuck.

Anyway, the microphone is on the right-hand side, and it only has one play/pause/accept call button. The cable is also totally replaceable, a good redeeming point for the design.

Another hiccup happened when I tried to connect the earbud to the cable. Just which side is which? That took a lot of squinting to figure out. Not sure if you can see it, but there is actually an “R” embossed on the crystal connector. I know it’s a one-time connection effort, but can’t the designers make “left” and “right” clearer? Don’t make us squint so hard?

But credits have to be given where due, the metal-plastic earbuds have some serious good build quality. No sharp edges and they are solid.




I have no complaints about the build quality so far. But the design… Sorry to the people who like it, but I really have some beef with it:

  • Dirty brown cable with sheet metal earbuds. What is it supposed to be? Vintage and/or industrial?
  • Combine that with colorful clear plastic. What is that supposed to look like again?
  • Overall, I will just call this a “very confused design theme”.




The sound quality is kind of hard to describe in words, but I will give it an overall “mighty decent good”.



  • Lows – Not really “powerful bass”, but more of “balanced bass”. Not too deep, not intrusive.
  • Mids – Produces some good mids and vocals.
  • Highs – A couple of high notes hit irritating-sharp… Something about the driver is trying to push things way too hard.
  • Clarity & Soundstage – Good clarity and soundstage. More wide than deep (direction, not distance).

Overall, the ZSN Pro has a decently good balanced sound profile. It will do just fine… Just avoid Soprano and “sharp instruments” such as violin and cymbals.



This thing has some good passive noise isolation. I guess the big metal earbud does block out noises quite a bit, and as the manual warns – Don’t wear this while driving. Slap some of your own foam ear tips on, and I am guessing that will make it perfect.




That’s all for this review, and here is a small section on some extras and links that may be useful to you.



  • Frequency Response: 7Hz to 40KHz. Something I don’t understand. The average human hearing range is 20Hz to 20KHZ, so what’s the point? You get to boast “my earphones can produce sounds that dogs can hear”?
  • Impedance: 24 Ohms
  • Sensitivity: 112 dB



  • Respectable balanced audio profile.
  • Good and solid overall build quality.
  • Replaceable cables.
  • Excellent value-for-money.



  • Highs can be piercingly bad at times.
  • Not visually appealing.



It has been months since I bought the KZ KSN-Pro. Nothing is broken, and this is still one of my “main earphones”. So yes, these supposedly “cheap earphones” have some good quality.

Also, KZ offers some good versatility with swappable accessories – Foam earbuds to further improve the noise isolation, silver/gold cables if you don’t like the dirty copper, even a Bluetooth adapter to turn this into a pair of wireless earphones. I can easily use this for many more months to come.



The ZSN Pro came in strong with a good build and sound quality, but it is not without flaws. The high range is a bit of a bummer, and the design… is up to your preference. However, for only 20 bucks, this is an easy no-brainer – This is a really good buy if you are on a budget. Highly recommended.

Thank you for reading, and we have come to the end of this review. I hope this has helped you, and if you have anything to share, please feel free to comment below. Good luck and may the cyber force be with you.
