KZ AS06: Singularity

Hello everyone!
Along with the V80s, Sherry sent me the KZ AS06 for FREE as well.
I was very curious about these IEMs as they were a full BA cheap setup and i really wanted to try them out.
I really wanna thank Sherry for the gift he sent to me: a 4.4mm Balanced cable with 0.75 pins, which is really appreciated.
Getting these free does not actually influence my final thoughts.

You can buy the KZ AS06 from Yinyoo at the link you’ll find at the end of the review.

Just wanna precise that my impressions are subjective and that listening experience can change depending on source, tips and so on. 

Test were made on:
– Galaxy S7 Edge Smartphone
– Presonus AudioBOX iONE connected to my PC with no Enhancements actived
– AGPTEK M30B/Benjie S8 DAP
I even connect my Fiio A3 when i need it if i hear some earphones need a little more power.

Technical specs:
Drivers: 3BA
Sensitivity: 105dB
Impedance: 15ohm
Frequency Response: 20 Hz – 40000 Hz
Cable lenght: 1.2m Detachable (0.75mm PINs). This is the NON-mic version but there’s a MIC versiona avaiable too.
Plug Type: L-type 


Classic minimal carton package by KZ. Sliding it up will just get you in front of a transparent plastic that covers the IEMs.
You’ll find then the cable, 3 pair of classic starline tips by kz and an instruction paper.


Cable is quite the same that KZ provides with CCA C10, KZ ZS7, but the connector to the IEMs has a different approach and the ear hooks are pre-made.
Cable is a bit prone to tangle and does not feature mic in my case but there’s a mic version too.
It feels solid overall even if i prefer a softer touch when it comes to the cable.


Shell is completely made of good quality plastic and feels well assembled. I personally like the design except the black glossy internal side which easily becomes a fingerprint magnet.
It really looks like a smoother version of the ZS10 shell, which i unfortunately do not have for a direct comparison.
The nozzle grill came a bit out of position in my case as you can see by the photos.
There is a little vent on the internal side but no vents on the rear side.
There are some very little nozzle lips around the end of the nozzle.
3BAs are featured in every shell.


The AS06 are very comfortable in my case. I thought they were really big considering many things people said about the ZS10 and AS10 shell (which seem very similar to the AS06 one).
Isolation is good as the design is closed back, way better than with the ZS7 and other open-back designed IEMs.
Stock tips didn’t do the job for me, i’m still searching for comfortable tips (the white ones in the top image are not the stock ones).


Let’s get into it.
Now the critical factor that decides if something has to be tried or not: how do they sound?
I mainly listen to EDM subgenres, Dupstep, Future Bass, Euphoric Hardstyle, Bass House, Midtempo and downtempo, darkwave, drum’n bass, but i even listen to many vocal tracks, moreover female ones.
I always search for IEMs that have a little bit of emphasis in the lower region, and can sacrifice mids with some recession if they still sound clear and natural. I love vivid and sparkling highs if they’re not at a headache level. 
V-shape signature is my favourite one. 

Lows: I have to say i didn’t expect any kind of punch from these in the low region.. I’m surprised: sub-bass is shy and It is not comparable to other V-shaped KZ products like ZS6/ZS7/EDR1 and so on, but that’s intended in the type of product.
Bass is well textured with great speed, depth and resolution. It actually has awesome impact and visceral feeling. Quite impressive for a BA configuration on a budget product, even because we have a BA config which punches way above expectations in my opinion.

Mids: Fairly laid-back sounding. Male voices are well rendered even if not on the “warmer” side.
Female voices are intimate and delicate, and sound with enough air to be appreciated.
Synths play in the backseat but not in a bad way: mids are recessed but not like on other products like ZS6 where the V shape is strong and very noticeable. I would say more of a U-shape.
No sibilance except some recordings which are prone to do that.

Highs: Bright, vivid and detailed. Details are here and there and i do not feel i need more.
These are sure less bright than V80s or ZS6, and even less fatiguing for long listening sessions.
There is a good extension of the upper end which gives the AS06 enough air to show its capabilities.

Soundstage is wider than deep. Height is average. Instrument separation is very good and imaging is great with good instrument positioning. Tracks with many layers will not sound congested and everything will be where it’s intended to be.


KZ offers a full BA configuration with 3BAs per earpiece. If you think bass response is poor, then i was thinking the same thing, but i was really surprised once i’ve put them in my ears.
The U-shape is nothing new in KZ lineup, but the AS06 comes with a freshier and more analytical approach compared to other KZ products which are more oriented to a very colored, aggressive and funny V-shaped sound. Technical ability is surprising.
Given the good and lightweight plastic build, the comfortable design and the good sound, the AS03 can be very interesting, even if they have to fight many competitors at this price range.





Build Quality


Comfort (subjective)







  • Analytical and smooth V-shape
  • Good build quality
  • Comfortable, no sharp edges
  • Nice bass response considering this is a cheap full BA product


  • Cable prone to tangle
  • Bassheads could be a bit disappointed by the sub-bass which is not extended like other V-shaped KZ products
  • Stock tips aren't enough as these need a bit of tip rolling
  • Much competition at this price point, even if they're really good, as many people just search for strong v-shape and mainstream sound signatures
