Low, Medium, High, Ultra-High Frequency​

All Have Different Drivers Responsible for Accuracy
The dynamic driver handles the mid-to-low frequency range, delivering ample low-frequency response and natural mid-frequency transitions to enhance the music's dynamics and atmosphere. On the other hand, the balanced armature drivers excel in the high-frequency range. Its compact structure and rapid response allow for precise reproduction of high-frequency details, resulting in a clear and transparent sound texture.

New Head-Fier
KZ ZS10 Pro 2 Review!
Pros: A refined, cleaner-sounding KZ Classic!

All rounder, mild V-shaped sound signature (subjective)

Clean, non-lacking, mildly elevated lows.

Clean, open mids.

Extended, airy treble.

Above-average technical performance under 40 USD!

Versatile tuning switches!

Very good build quality.

Very good fit, comfort, and isolation.

Easy to drive.
Cons: BA timbre is apparent in most tracks in my library.

Instances of peaks and mild sibilance are present in certain tracks.

IEM can be bulky for smaller ears.

Barebone accessories, they even forgot to put a medium sized silicone eartips in my unit (could be an isolated case, but a good heads up)

While a very good improvement over the ZS10 Pro X, ZS10 Pro, and the original ZS10, this IEM does not sound dramatically different when compared to other KZs that have recently existed.

KZ ZS10 Pro 2 Review!
Good day! After 5 days of casual and critical listening, here’s my written review for the KZ ZS10 Pro 2. A classic refresh!

​
=================================================================================================================
Disclaimer:
  • I don’t read FR graphs. I only use my ears, as how earphones should be used.
  • KZ has sent this unit to me in an exchange for an honest, unbiased, independent review. Rest assured that this review will do its best to devoid from any bias/es as much as possible.
  • The following remarks and observations shall be made and owned only by me.
  • No monetary compensation is/was involved before, during, and after the period of creation of this review.
  • Your mileage may (and always, will) vary.

Burn-in time: 4-8 hours per day, 5 days.

Source/s used:
  • - Non-HiFi smartphone (Infinix Note 12 G96), PC.
  • - Tanchjim Space DAC
  • - Kiwi Ears Allegro DAC
  • - Hidizs S9 Pro DAC
  • - Simgot DEW4X DAC
  • - Aiwa XP-V710C CD Player (12 sec. EASS)
  • - Sony Xperia X Compact
  • - Local Files via Foobar, YouTube Music, Deezer, and Qobuz with UAPP.
IEM/Earbud/Setup configuration: Stock large silicone eartips,, any form of EQ or MSEB off, 40-60% volume.

(Additional note here: I’ll evaluate the ZS10 Pro 2 first in its stock configuration where the switches are all switched on (UUUU). I’ll explain and compare it to other IEMs right after.)

=================================================================================================================
Sound signature:
  • Just like its previous ZS10 siblings, the ZS10 Pro 2 kept its faith to their usual mild-v sound signature, which leans to the brighter sound signature. What makes this different from its siblings is the absence of bloat from their previous variations, making the overall sound more mature and nearly clinical. This also affected the technical performance in a very positive way.
Lows:
  • The lows are mildly elevated , but lack the bloat that are found in the previous ZS10 generations, in general. It is still midbass dominant and leans to the faster side of the spectrum in terms of attack and decay. Subbass is still present, does its job, shows where and when it is needed, but never becomes too “ear-shaking” or overly chunky, which may dissatisfy bassheads. However, the bass on this set will be more than enough for most people and their playlist in terms of quality and quantity for its respective retail price.
Mids:
  • The mids are still mildly recessed, but are much more cleaner and vivid when compared to the ZS10 Pro. Midbass bleed or bloat is nowhere to be heard in this set, or non-perceivable to my ears, at least. This also means that the lower mids trimmed a bit of weight and depth. Upper mids are still elevated, clear, and have a decent amount of air. As for the mild peaks and harshness, it is still apparent in this region, which made me not recommend this IEM for those people who are very sensitive to bright upper frequencies.
Highs:
  • As for the highs, it is definitely bright and elevated on this set. The ZS10 Pro 2 avoided unusual sibilance and harshness in this region, But I will still not recommend this IEM for those people who are very sensitive to upper frequencies and BA timbre. The treble extension is decent and airy. Detail retrieval is average at best.
Soundstage, Imaging, and separation:
  • This region is the most noticeable improvement that the KZ ZS10 Pro 2 has. It is more technically capable when compared to its previous siblings. The soundstage is wide with a good amount of depth and height. Separation and layering are above average for its price and handles very busy tracks. Imaging is accurate and renders vocal and instrument positions quite well.
=================================================================================================================
Other Switch Configurations!

DDDD config
  • This configuration is also mild-v in terms of sound signature, both ends of the spectrum are less elevated compared to the UUUU config. Technicalities also took a hit on this configuration and sound more “flat” to my liking, particularly on the soundstage.
UUDD config
  • This configuration elevates the lows and tones down the upper frequencies, making things sound more thick and warm. This however hits the soundstage as well, in terms of width and height.
DDUU config
  • This configuration elevates the upper frequencies, giving its sounds a sense of air and very good resolution. Technical performance is also affected positively in this configuration, at the expense of more frequent peaks and mild sibilance.
=================================================================================================================
Other IEM Comparisons!

VS 7Hz Salnotes Zero 2
  • The Zero 2 is a warmer, more balanced sounding set. Mids are near neutral on the Zero 2. Its treble however lacks extension and air to my ears. Technical performance is better on the ZS10 Pro 2, particularly in its separation and layering.
VS Simgot EW200
  • The Simgot EW200 is a more neutral sounding set compared to the ZS10 Pro 2. Bass is near neutral on the EW200. Mids are also more open on the EW200, and both sets exhibit unperceivable bloat nor bleed. Treble is more airy and extended on the EW200. Technical performance is better on the EW200, but not by much when compared.
VS Etymotic ER3SE
  • Both exhibit some BA timbre, but the ER3SE has less of that when compared. The ER3SE is also dead flat to my ears and does its best to render the actual sound of the track and source paired with it.

=================================================================================================================
Pros:
  • A refined, cleaner-sounding KZ Classic!
  • All rounder, mild V-shaped sound signature (subjective)
  • Clean, non-lacking, mildly elevated lows.
  • Clean, open mids.
  • Extended, airy treble.
  • Above-average technical performance under 40 USD!
  • Versatile tuning switches!
  • Very good build quality.
  • Very good fit, comfort, and isolation.
  • Easy to drive.
Cons:
  • BA timbre is apparent in most tracks in my library.
  • Instances of peaks and mild sibilance are present in certain tracks.
  • IEM can be bulky for smaller ears.
  • Barebone accessories, they even forgot to put a medium sized silicone eartips in my unit (could be an isolated case, but a good heads up)
  • While a very good improvement over the ZS10 Pro X, ZS10 Pro, and the original ZS10, this IEM does not sound dramatically different when compared to other KZs that have recently existed.

=================================================================================================================
Verdict​

KZ is on a roll on “refreshing” their popular sets that have existed before, to keep up to the Chi-Fi’s saturated market and balls-to-the-wall standards. The ZS10 Pro 2 exhibited those standards well for its asking price, in terms of overall technical performance. Looking at a bigger picture however, it struggles to stand out among its competitors for its asking price. Don’t get me wrong, the ZS10 Pro 2 never sounded bad to my standards and preferences, but this won’t definitely be the first IEM that I will recommend for its asking price, due to the fact that its own sibling from the same company, the CCA Trio, is better for less money.

Pairing recommendation/s:
  • Source: This works well with neutral sources you pair it with, but this will suit better with warm sounding dongles, such as the Simgot DEW4X as an example.
  • Eartips: The included eartips hinder the sound of this IEM, so I suggest using a better eartips such as KBEAR 07s, Tri Clarions, Final Es, or Tangzu Tang Sancais.
  • Cable: The cable also hinders the fit a bit to my ears due to its preformed earhooks. NiceHCK cables work well with this set in terms of comfort.
Thank you for reading!

A good direction for a legend
Pros: Lightweight build, nice balanced signature with quality Bass.
Cons: Fans may or may not like the departure from the Vshape that the OG had. Mids are slightly recessed.

The KZ ZS10 Pro 2 is the fourth-generation variant of the long-running ZS10 series. It features a 1DD+4BA hybrid driver configuration and comes with four tuning switches. Here are some key points from various reviews:

Design:
The shell design of the ZS10 Pro 2 is similar to its predecessor, the OG ZS10 Pro. It retains the aluminum faceplates with crisscross slits and a see-through resin housing, the four tuning switches on each earpiece allows for customization with a minor increase and decrease in Bass. Inside the small box is very simple accessories and the typical KZ cable and tips.

Sound impressions:
The new ZS10 is different from previous models that leaned toward a traditional V-shaped sound signature, the ZS10 Pro 2 is a more balanced and mature tuning.

Bass: Bass is well controlled and deep without stepping on the other frequencies, there is no bloat.
Mids: The midrange presents forward but not in your face vocals with good focus. Both Male and Female are well defined but, on some recordings, there is a little recession in the midrange in general.
Treble: The Highs are decently detailed with good air and without harshness or sibilance at normal volumes.
Overall, it provides an engaging sound across genres from EDM to jazz1.

The KZ ZS10 Pro 2 delivers energetic, engaging sound with very good technical performance for the cost.
It features impactful bass, energetic treble, wide staging, and above average detail separation for a budget hybrid In Ear.
In summary, the KZ ZS10 Pro 2 offers excellent value for its price, its a good choice for a fun and engaging IEM that is not too expensive or harsh.

Thanks for the review, my son and I were discussing this IEM yesterday, was going to wait for sales. I have the Pro X is the sound much different if you have heard both?

Yes it is much different. The X was more of an improved Vshape of the OG. this one is more of a wider V with better control on both ends (Bass and Treble).
