The KZ EDX Pro was released in 2020 as an upgraded version of the more famous KZ EDX

It features a similar shape with some minor changes in the design, including an aluminum faceplate. 

It has a V-shaped sound signature, which means it has elevated bass and treble frequencies and a recessed mid. This results in a good mixture of a punchy low end, a sparkly treble frequency, and scooped-out mids.

First Impressions

The KZ EDX Pro came in standard packaging, which is what you’d expect with budget IEMs.

Although its packaging isn’t fancy, the earphones were securely packed in the box and they came looking exactly as I expected. 

Upon closer inspection of the EDX Pro, I noticed many differences when comparing it with the KZ EDX. The most noticeable difference is the updated design that the EDX Pro has.

The accessories were pretty basic. The earphones only came with extra silicone ear tips in verifying sizes and a 2-pin detachable cable that’s silver-plated, similar to that of the KZ ZSN Pro.

Build Quality

The KZ EDX Pro and the accessories that came with it were of decent quality.

The IEMs have a resin shell construction that looks rigid. It doesn’t feel cheap to the touch.

The detachable cable is also well-built which I found to be pleasantly surprising, especially for a budget set. I feel like they’ll last a long time with the right care.

Overall, I was delighted with the build quality and design of the KZ EDX Pro, and it’s definitely an upgrade compared to the EDX.

Fit and Comfort

In terms of fit and comfort, the KZ EDX Pro did great.

The IEMs provided a snug fit to my ears, which was unsurprising since it has a pretty universal IEM shape.

The included silicone ear tips were also very comfortable compared to my EDX, which is a massive bonus since there were times when I’d feel some discomfort after using the EDX for hours due to its cheap ear tips.

The cable and the pre-molded ear hooks weren’t loose and fit nicely around my ears. The cable also didn’t produce any stethoscopic effect when it rubbed against different objects, such as the fabric of my clothes.

Since the shell is mainly made of resin, the KZ EDX Pro is lightweight and very comfortable to wear, even during extended periods of use.

Sound Quality

After the unboxing and burn-in of the KZ EDX Pro, it’s time to talk about what really matters: the sound quality. 

Its low end stood out when listening to the test tracks as it was punchy and had a good amount of rumble. The bass tends to fall off during busier tracks and needs help to catch up when listening to more crowded tracks.


The KZ EDX Pro has a good bass response which is beyond my expectations, considering it’s a budget IEM. 

Compared to its predecessor, the EDX Pro features a good amount of extension on the sub-bass, which is a definite improvement.

The bass is well-balanced, has reasonable control, and doesn’t suffer from muddiness, unlike other budget IEMs. For its price, the bass response on the KZ EDX Pro is tough to beat.


The midrange is one of the weaker areas of the KZ EDX Pro. 

Due to its V-shape nature, the mids are recessed, which can result in warmth loss on the overall mix. Although this is slightly present on the EDX Pro, it still has decent clarity and detail.


The treble of the KZ EDX Pro was airy and very open, producing great detail and clarity, but it does suffer from treble peaks depending on the tracks you listen to.

Although the treble can sound too bright and harsh at times, I experienced no sibilance when listening to the test tracks. Even so, I recommend EQ-ing out some harsh frequencies on this IEM for a more enjoyable experience.

Overall, the EDX Pro has a decent treble response that can work well with specific tracks.

Test Tracks

I’ve tested the KZ EDX Pro on different genres of music to get a proper understanding of how they sound. Here are my findings.

KZ EDX Pro Cable
Standard 0.75mm 2-pin gold-plated cable | Make Life Click
  • Metal / Rock – The V-shaped sound signature performed exceptionally well in this genre. The emphasis on the bass and treble frequencies on the test tracks worked well with the V-shaped sound signature, giving more depth and impact to the instruments, such as the drum kick and the distorted guitars. Tracks used: Brain Stew (Green Day), Reverie (Polyphia), Ignorance (Paramore)
  • Pop / Disco – The vocals and instruments were nicely presented, with each sitting well in the mix. I like how the V-shaped sound signature lifted the low end of the track, making them sound punchier. Tracks used: Get Lucky (Daft Punk, Pharell Williams, Nile Rodgers), Uptown Funk (Mark Ronson, Bruno Mars), Everybody Wants to Rule the World (Tears for Fears)
  • Hip-hop – The bass frequencies did most of the heavy lifting for this genre. The KZ EDX Pro’s sub-bass has a great extension that provided a decent amount of rumble, highlighting the instruments sitting on the low frequencies of the mix. Tracks used: 20 DEEP (O SIDE MAFIA), Dark Knight Dummo (Trippie Redd, Travis Scott), Sky (Playboi Carti)
  • Indie – The EDX Pro performed well in bringing forward low-end frequencies, which made the bass guitar more present in the mix. The lack of mids resulted in a loss of warmth to the guitars, which made the tracks sound a bit bland. On the other hand, the soundstage was decent, although it had a good amount of depth to them. Tracks used: Show Me How (Men I Trust), Space Song (Beach House), Queen of Disaster (Lana Del Rey)
  • R&B / Soul – The whole mix sounded lush, especially on tracks like Movie by Tom Misch. I was surprised that although the KZ EDX Pro has recessed mids, the guitars and other instruments retained their warmth, making the tracks more enjoyable. However, I experienced some treble peaks on some of the tracks, which was unpleasant. Tracks used: Movie (Tom Misch), Call Me When You Hear This Song (New West), Telepatia (Kali Uchis)

The KZ EDX Pro is a great budget performer when you consider its price. 

It may not be in the same league as the 7Hz Salnotes Zero but it’s still a pair of IEMs worth trying, especially if you’re on a limited budget.

The EDX Pro is a huge improvement from the EDX with its better sound quality and build quality. 

For around $15-$20, the KZ EDX Pro is a good pair of V-shape IEMs to consider.
