Sound quality description

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

 

The KZ EDX Ultra has a sound balance of a full midrange with a neutral sound in mind, and these IEMs carefully listen to the highly transparent midrange.

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

 

The KZ EDX Ultra is a fairly well-crafted IEMs that suggests that KZ is learning to tune better, unlike in the past. However, it is not for everyone, as there is a definite weakness in the high frequencies.

 

Personally, in the same price range, I would recommend the CCA CRA for highs and lows, and the Tripowin Lea for mids.

General comment

The KZ EDX Ultra is an excellent IEMs with audio specs and build quality above its price point, but it has the disadvantage of being habitual in the high frequencies, which can easily become a weakness. It is likely not suitable for those who are sensitive to high frequencies, as they will feel the sting, and that is the only drawback, but other than that, it is a relatively easy choice to recommend.
