Sound quality description

In this review, I use the standard eartips size L and drive it with the FiiO M15.

 

The KZ ZEX has a loose W-shaped, or rather V-shaped, variant of its sound signature. It has a warm, full sound with excellent dynamics, which makes it rather enjoyable to listen to, but it has a tendency to sound thick and dense, so there is a sense of pressure in the midrange. Also, the sound image in the midrange is basically flat and lacks developmental power. You may enjoy the unique depth and dynamism of the sound.

Sound quality general comment
  • Original Sound Fidelity: A
  • Recommendation: B-
  • Personal preference: C+

 

The KZ ZEX is a strange earphone that has a terrible sound balance with excellent drivers. In other words, what you have there is the usual KZ.

 

It's a typical example of earphones that no matter how good the drivers are at a low price, if the tuning is bad, everything is ruined.

General comment

The technical performance of the KZ ZEX is excellent, offering a sound comparable to the high end for an earphone that costs just under $30. However, the tuning is not to everyone's taste, pursuing the usual KZ hobby, and basically it is very niche and only a few listeners will be satisfied with it. The score looks good because of the large amount of points added for technical performance, but the recommendation is below mediocre. In other words, there's the usual KZ out there, who likes to make weird sounds with great material.
