The Packaging Build & Design Sound Quality
Summary 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.



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.
