VJJB N30 – Alien Rumble!

Hello everyone!
This time i’ve received a strange pair of IEMs by AK Audio which i really thank for their trust in my reviewing activity. They said me they would have looked like “aliens” and, in fact, i’ve noticed it as soon as i opened the package. Let’s see if they could be “aliens” even speaking about performance!

You can buy the VJJB N30 from AK Audio by clicking on the link 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: 2 DD + 1 BA
Sensitivity: 96dB
Impedance: 20ohm
Frequency Response: 20 Hz – 24000 Hz
Cable lenght: 1.2m (MMCX Connectors)
Plug Type: Straight gold plated 3.5 mm jack


Packaging is really another level: reaching this brand after many reviews of KZ, CCA, TRN products, we have something new.
The packaging is really premium with a carton box that shows elegance as soon as we open it. Every tip takes his own position while we observe the IEMs on the right side. A real nice presentation of their product. The package cointains 7 pairs of different tips (including a pair of foam tips), IEMs, a cable with MMCX connectors and a very appreciated soft bag in which you can store your IEMs on the go.


Cable feels stiff in the hands, but well built. It doesn’t feel cheap and has rubber ending near the MMCX in order to provide more grip when plugging the connectors in and while removing them.
It features an appreciated rubberized chin slider and in my case a microphone with a multifunctional button (works well on android, i can answer to calls, play and pause and so on).


IEMs are mostly made of plastic but feel solid. There are some little imprecisions here and there but nothing that really changes my opinion of a well built product.
They’re transparent, so that means you can easily see what hides inside alongside with driver connections and so on. This is a triple driver configuration which is not really common as many of you could think, as many brands prefer going on 4/5 drivers or just hybrid dual drivers configurations.


In my ears, they are very comfortable. Their strange “alien” look and shape justify their rounded shell making them really comfortable for long listening sessions. Imho, one of my most comfortable IEMs (even if not at the level of ZS10PRO, CCA C10’s – and so on- shell, which i really love).
Isolation is fairly good, but even in this case something like the CCA C10 wins hands down. The metal faceplate is maybe a bit harder for surround noises to be penetrated compared to plastic. Considering the good variety of tips, i guess you’ll not need buying another pair of tips, except the case you have your own favourite tips and wanna put them on these.


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 usually my favourite one but in the last period i’m appreciating a more balanced presentation with less recessed mids, more of a U shape.

Lows: great low end! Punchy, agile and fast bass. These DDs do a very good job.
Kickdrums hit hard maintaining a well textured structure. Sub-bass is extended and rumbles when called. Bass tends to intrude in the midrange in many cases but that’s not necessarily a good thing if you’re used to this kind of sound signature.

Mids: mids are recessed. Compared to other IEMs that i have, the midrange is more recessed. I would say recession level is at EZ Audio D4 level.
Male voices have a nice warm touch while female voices are a bit shy and distant and feel too much warm at times. Midrange still sound clear but be aware these have a good amount of recession so if you’re searching for something to listen to instrumental tracks, search elsewhere, maybe something with a more forward midrange.

Highs: they are not fatiguing at all. Perfect for people who cannot stand treble. Being the bass really powerful, the upper range tends to be warmer, with little sibilance just in some rare cases where songs are prone of being sibilant. Detail is average with plenty of air, nothing outstanding anyway if we compare it to some competitors.

Soundstage is average being deeper than wider with limited height . I would say these are more suited for a “narrower” or “little” stage experience.
Instrument separation is a bit below my expectations but imaging is fairly good.

Now some comparisons:
vs Revonext QT5
Same price range but i wanna start with a little premise: the QT5 have another kind of signature.
QT5s have a more forward midrange with much more detail, a better instrument separation and imaging. Bass on the VJJB N30 is more powerful and more suited for EDM, hip-hop and electronic music. Highs are brighter and more detailed on the QT5 (with a little more sibilance that can appear in more cases compared to the N30). Soundstage is wider on the N30 but deeper on the QT5, with better height. The QT5 are heavier than the N30 but not by a huge margin and comfort is on par (at least in my case). The N30 are easier to drive while QT5 are much more source dependent and needs a bit more energy to carry out their full potential. Imho, even if the QT5 have another sound signature, they represent a better value for people searching a more technical and musical IEM, not only in this price range. They’re really hard to beat.

ZSN PROs are fairly new in KZ’s lineup, and part of their new PRO line which re-offer some old named IEMs by them (ZS10, ZSN and so on) with a renewed tuning and configuration.
Soundwise, their sound signature is quite different. While the VJJB N30 is super emphasized on the lower end, the ZSN PROs are punchy and boosted but not as much as the N30
Sub-bass is more extended in the VJJB N30 providing a stronger rumble.
Midrange is more forward in the ZSN PRO, with little better detail and instrument separation. Imaging is on par. Highs are more fatiguing on the ZSN PRO while the N30 are really pleasant to listen in that region: they’re warmer and do not sound aggressive. Plus, ZSN PROs tend to be more sibilant compared to the N30. Soundstage on the ZSN PRO is wider while it’s deeper on the VJJB N30. Height is on par with little to no advantage for the ZSN PRO.

vs MEMT x5
These are included in my first IEMs list that i have bought before diving into the Chi-Fi train.
They were hyped for their killer value at their time, and many people were speaking well about’em.
I used them as my daily drivers for more than a year.
When i received my N30 i instantly got back in the time when i was wearing my MEMT x5.
I think the N30 are a direct upgrade of the x5 in terms of signature and technical performance. Sound signature is practically the same with strong mid recession, powerfull bass and sub-bass response, not fatiguing and easygoing high end. Soundstage is better on the N30 being wider and deeper with identical height. Technically, N30 are more refined with a more authoritative timbre, but the x5 are a bit better while resolving female voices. Imaging and instrument separation are better on the N30. At the price they’re being sold, i would buy the N30 instead of the x5, except the case you prefer standard bullet earphones. I’d say VJJB showed us they can really dig it when it comes to a precise target and they’re now offering a real deal for bassheads or hip-hop fans out there, with a great package overall.


I didn’t know VJJB brand, which actually impressed me with their great packaging, variety of tips and a very good cable.
Soundwise, they’re fun, with a very powerful bass response: i would really advice these to some bass maniacs friends as bass here is really punchy and engaging. Performance-wise, they didn’t blow me away. I think there are better choices out there at the same price range: something like the QT5 represent a real killer value in this market segment with actually a few IEMs that can still compete around 20$, but they have another kind of sound signature and could not suit bass maniacs tastes.
Great job VJJB, can’t wait to try something new from you again.






Build Quality


Comfort (subjective)







  • Huge bass response, well suited for bass maniacs
  • Comfortable
  • Great cable
  • Superb packaging, good variety of tips, alongside with a nice carry bag and a great cable
  • Super fun signature. These are highly market-targeted headphones, offered for a precise segment which includes bassheads


  • Highs are not as detailed as many of its competitors
  • Technical performance is just average, i expected something better in terms of technical ability
  • Sound signature is what implies many of these things, so this is a kind of sound signature which cannot be an allrounder's one
