KZ ups the ante within the IEM driving force and tuning transfer wars – excursion de pressure or torment?
Simply once I idea the driving force wars have been finishing, KZ launched the AS24 with 12 balanced armature drivers consistent with aspect. Then KZ upped the ante within the tuning transfer wars with 8 tuning switches consistent with aspect, additional fueling the contest.
The AS24 are a very simple advice, particularly with the sort of favorable price-performance ratio. I will be able to’t believe any person being dissatisfied with the AS24 until the dimensions and are compatible don’t paintings or any individual is in search of IEMs with a definite signature energy (e.g., tough, ear-drum damn bass). The AS24 are mature, balanced, and extremely versatile if in case you have the time and persistence to experiment with myriad refined sound distinction probabilities.
- 8 tuning switches!
- Superb are compatible and end
- Distinctive, simply recognizable, and tasty design
- At ease for lengthy listening classes
- The inventory tuning could be very effectively achieved (extra impartial than KZ has a name for)
- The tuning could have vast attraction; the AS24 plays effectively throughout maximum genres
- Total technical functionality is extremely aggressive in the fee vary
- Crossover implementation is shockingly easy, with very good coherence
- No noticeable BA timbre or harshness
- Element with out fatigue
- Superb bass texture and musicality for an all-BA IEM
- Implausible price for functionality
- 8 tuning switches!
- Loss of top class equipment for a flagship product; no raise case
- Ear tip choices are a long way too restricted
- Bass authority and affect are extremely ear tip dependent
Are the driving force and tuning transfer wars finishing? Or simply starting?

Unboxing and First Impact
Corporate Assessment
KZ (Wisdom Zenith), founded in Dongguan Town, , started as a definite logo in 2013. In 2018, KZ received whole independence in analysis and construction with their very own manufacturing facility and equipped consumers with a complete supplement of OEM/ODM services, together with stressed out and wi-fi IEMs and headphones.

Packaging
The small, simple black field is useful and environment friendly. KZ claims that the field and fabrics are a extra environmentally pleasant resolution. Small, easy, neat, and environment friendly. Equipment are minimum, with a couple of ear guidelines, a cable, and a device to regulate the tuning switches. There’s no raise case integrated.
Within the field
- KZ AS24 IEMs
- 3 pairs of silicone ear guidelines (S, M, L)
- One pair of froth guidelines
- SIM card removing software
- Pamphlet/fast get started information
Cable
The 1.2m high-purity silver-plated OFC flat cable is sexy and light-weight in weight and look. The cable turns out fine quality, an important step above the standard useful but flimsy cables accompanying maximum entry-level IEMs. The two-pin connection suits completely and is safe.
There are 0 microphonics, which is actually track to my ears and yours.
The “flat” cable is 2 wires certain side-by-side from the plug to the splitter, leading to a really feel of being flat. The left and proper cables then separate into unmarried spherical wires. The cable is slightly tangle-free and feels relatively sturdy. In contrast to braided cables, there’s not anything to return free with common use.
The cable’s ear hooks are extremely safe, if a little stiff, leading to a comfortable are compatible. Till they melt a little, the ear hook force can compromise a excellent IEM seal. I skilled this till I discovered the best-fitting ear guidelines and used the cable sufficient to melt up the hooks.
Construct & Design
The construct feels well-made, and the are compatible and end are very good. There are not any tough edges. The ergonomic form is beneficial to offset the dimensions and weight. The AS24’s face is sexy in individual and doubles as ear jewellery.
The AS24’s frame is constituted of a number of major items: a DLP three-D published light-weight, skin-friendly resin frame, and high-precision built-in acoustic filtering nozzle, a glowing diamond-cut bracket, and a gentle steel entrance duvet.
The nozzle is of average-long duration, with a notched collar to safe the ear guidelines, which is helping with deeper insertion to offset the bodily dimension of the our bodies. A steel acoustic filter out is situated on the finish of the nozzle.
Two variations of the AS24 are to be had – tunable and non-tunable.
The tunable version shall be a really perfect supply of dialogue for the AS24. There are 4 number one (Primary) and 4 secondary (Auxiliary) switches consistent with aspect. When you’ve got a hawk’s eyesight (or a jeweler’s loupe), and a surgeon’s stable hand with the equipped SIM card removing software, you’ll alter them.
Convenience
Their low weight (for his or her dimension) and ergonomic form cause them to manageable. The shape provides me no discomfort on its own, rather than adjusting them periodically to stay them from angling out and compromising the seal.
The AS24 don’t seem to be for small dainty ears.
The upside of the dimensions is that the our bodies are simple to maintain and alter. The shells really feel considerable in hand. Because of very good ergonomics, the frame makes no touch with my outer ear, and they don’t really feel heavy in my ears. I will be able to put on them for hours with out trouble or fatigue.
Internals
The AS24 has 12 BA drivers consistent with aspect of various sorts and particular jobs to accomplish:
- 29689 BA x2 = 2 BA for mid-frequencies
- 31736 BA x4 = 8 BA (every 31736 BA = 30019 BA x2) for prime and ultra-high frequencies (treble and “air”)
- 30019 BA x1 = 1 BA for high-frequencies (treble)
- 22955 BA x1 = 1 BA for low-frequencies (bass)
KZ AS24 Sound
For analysis, I pay attention to a really perfect number of track via a large number of resources, together with:
With a low impedance of 20-50 ohms and a excessive sensitivity of 109±5dB, the AS24 are really easy to force. Insertion intensity is common and can yield above-average passive sound isolation with adequately seated and sealed ear guidelines.
I’ve no longer had luck with the equipped guidelines, particularly the froth. Convenience got here at the price of choking off the sound switch into my ear canals. My most popular guidelines are a borrowed pair of silicone guidelines from the Bang & Olufsen Beoplay H3 and silicone YINYOO Tri Clarion guidelines.
After being attentive to the AS24 with all switches off, I started the tedious (for me) activity of toggling via myriad mixtures. Now, I’m happiest and maximum engaged with all switches on.
The tuning switches don’t radically adjust the sound or timbre.
Consequently, my critiques follow to the whole sound of the AS24, irrespective of transfer configuration.
The frequency reaction is definitely achieved in all configurations. The sound signature is mature and balanced. The AS24’s sound is extremely detailed with crisp readability, higher than maximum dynamic drivers can set up. All of the whilst, transitions stay easy. The crossovers are so effectively carried out that the ensuing coherence is really unexpected.
If you happen to love to tinker, the tuning switches will allow you to make small adjustments to the frequency reaction for your center’s content material.
The AS24 showcase very good dynamics with nuance. The soundstage is spacious, and the imaging is actual. Smartly-timed assault and rot make for life like timbre and excellent tonality, which is relatively an accomplishment for all-BA driving force IEMs (particularly with 12/aspect!).
For this assessment, I visited the next artists and their house places:
An enchanting assortment from a number of continents, those numerous musical productions vary in ethnic origins, musical kinds, and explorations in audio.
Bass
For a BA driving force, the bass copy is authoritative and wealthy whilst final blank and well-defined. When all switches are on, the higher bass can somewhat step at the midrange with particular compositions. Notice weight is somewhat skinny in the event you want heat, thick, bass-heavy sound signatures.
What the bass lacks in sheer amount, it simply makes up for in high quality and musicality.
Bass supply is enjoyable and suitable for the majority genres. The bass extension is deep and not using a roll-off. I heard no distortion when listening at average to loud volumes (for trying out). They ring a bell in me of planar drivers with a somewhat much less sharp assault.
Answer and texture are very good for herbal tools similar to cello, upright bass, and timpani.
Midrange
The midrange sounds herbal, transparent, and full-bodied in all track. You’ll be overjoyed with the AS24 in the event you basically pay attention to vocal-centric track. Regardless of what the graph would possibly recommend, the mids by no means shy towards the again. They’re easy and don’t come throughout as shouty.
Treble
I’m inspired with the treble tuning and capacity. The treble is full of life, revealing, and detailed with out inflicting fatigue. I’ve but to be indignant through sibilance, ordinary BA sharpness, or undesirable shimmer. The treble brings very best stability to the wealthy, musical bass.
The place to Purchase
Conclusion
The AS24 are actually very good, with few reservations. They’re a very simple advice, particularly with the sort of favorable price-performance ratio. I will be able to’t believe any person being dissatisfied with the AS24 until the dimensions and are compatible don’t paintings or any individual is in search of IEMs with a definite signature energy (e.g., tough, ear-drum damn bass).
KZ is coming into a new generation of adulthood in its product construction and tuning to attraction to a extra discerning audio-enthusiast target market of prolific consumers who upload new IEMs continuously to their collections.
For tinkerers, the tuning switches will supply numerous hours of a laugh. Toggling switches off and on shall be extremely enticing, entertaining, and enjoyable. For others, this can be an frustrating chore that may be extra temporarily completed via software-based EQ.
The AS24 are mature, balanced, and extremely versatile if in case you have the time and persistence to experiment with myriad refined sound distinction probabilities.
