Latest reviews

Pros: Incisive presentation
Exciting listen
Great build and comfort
Cons: Sharp and edgy upper midrange and lower highs
TRN has just introduced its latest model to the market and it’s called VX. It comes with whooping 7 drivers and costs around 70 bucks. Ten bucks per driver sounds like a good deal, right? Well, at least in terms of quantity but I was more interested in their quality and skill of producing high fidelity sound. Let’s dig into it and find out.

Build, fit, and cable
TRN VX is made of aluminum and coated with a pint that has a kind of soft-touch feel to it that’s very pleasant. It might not be apparent trough pictures, but there’s a real premium feel to VX. They’re not too chunky as one might expect considering the sheer number of drivers used. Moreover, these are fairly lightweight which definitely helps their ergonomics.

Talking about ergonomics, TRN VX fit great in my ears. Pre-shaped ear-hooks are soft and not too springy, so mounting these is a fuss-free experience. I know that’s a very personal matter but that said and judging by my experience, these deserve high praise for comfort.

Lastly, the cable is a typical braided solution, which means it tangles quite easily but on a positive note it’s not microphonic. It’s detachable too so you can opt for an aftermarket solution if you wish.

Sound
The first thing that hits you with TRN VX is how sharp and fast they sound. Starting with the baseline, it’s fairly decent in weight but definitely not suited for bass-heads or those who like their bass to lend warmth to the rest of the spectrum. This one is reasonably weighty but very fast and agile in return. Going higher you’ll notice a dip in the lower midrange which rips some body and weight from vocals and other tones. Then comes the empathized part of the upper midrange and a portion of high frequencies.

What this type of tuning means for your music is that TRN VX sounds lean and mean. That emphasis on the upper region is lending all the sharp details and leading edges you’d ever want. Now add to that energy and attack these in-ars posses and we get edges and transients presented in a ruthless and very analytical fashion. This character is sure flashy and exciting but definitely not the last word regarding finesse and musicality.

Other than that, the separation of individual instruments is great and the sound is quite spacious for an in-ear model.

EQ-ing
I found the sound signature of TRN VX to be a bit overzealous for longer listening, so I’ve decided to give EQ-ing a chance. I did it solely by ear and ended up with this:

– 3 dB at 4 kHz
– 3 dB at 8 kHz

The result was taming of those dominant regions just enough so I can listen for a longer period of time and actually enjoy the other qualities VX has to offer.

Conclusion
TRN VX possesses some nice and desirable qualities such as great premium build and comfort. Their sound signature is marked by class-leading speed, clarity, and sharp transients that’ll try to claw and bite their way into your heart. This aggressive approach will sure work for some but it will not suit all, especially the ones looking for a full-bodied and musical approach.

Unboxing and First Impressions

For their flagship In Ear Monitors, the trn VX box is very minimalist. I think trn aim for more shipping friendly. Trn vx shells are made of alliminun so it is very light and strong. My review units come with mate green color with three fin like shapes. I also notice there are two vent holes on both shell, therefore, drivers flex won't be an issue. The iems shell is at the medium small side and feels very comfortable to wear. The stock cable is usable but not quite amazing for this price. Thankfully, trn also offer me their newest cable which is guite good. Trn t4

Sound

Trn vx offers you high end resolution and fun sound signature for this price range and has good coherence for so many drivers , good sound stage and decent quality imaging.

Low frequency

Trn vx low frequency has a sense of quickness and quality. If you look at the frequency graph at 30hz and 60hz, it represents light and fast bass. Listening to a song called Let Me Love You by Justin Bieber, I can feel the vx bass quantity just right, fast and tight. Another song called Hang On To Your Love by Sade, snare drums pounding so fast and enjoyable. Again no lack of quality here from the 10mm dynamic driver.


Mid frequency

The mid frequency range of trn vx has a strong detailes and genetic forward vocals on the aggressive side. For example, the song called If You Wanna Be Good, You Gotta Be Bad by Bryan Adams,I can feel how his fingers play the guitar and listen to a bit more,and his voice sounds like he singing in front me and yet I don't fell congested. Every instrument plays its role beautifully. Guitar left and right, singer in front, and the drummer behind is amazing experience like I am on the stage with him. Another good example, a song called One Million Reasons by Lady Gaga, again her voice is so full of energy in a good way. I can hold my self but to stand to dance with the song.

High frequency

This set is a pure joy for treble head. Therefore, it can be too hot for people who like laid back iems. In my experience after spending more than 200 hours with the VX, I find the high is not so hot as when I just received it.This set is amazing for treble heads.
For instance, with a song called Bring Me To Life by Evanescence, counting every crush cymbals is almost impossible with some iems but trn vx performs with ease. It is a nice experience to hear such a great resolution. But without a warm dac, trn vx treble is a bit too hot with some songs. The easiest solution is to turn down 2k,4k and 8k by 3db.


Sound stage

The sound stage of the vx is quite good. It has more width than depth, so it has oval shape. I can clearly hear every instrument strike from left to right and vice versa, but it has small space.

Detail and Imaging

For this price range, trn vx give an insanely good imaging. From pop to metal rock music, the vx offers my brain of genetic, an urge to dance. As I said before this set is not for laid back or sitting in a arms chair. With this quality imaging and fit, it is for dancing!

Timbre

Timbre is average and on the fast side.
The VX has the balanced amateur driver timbre so it is quite good but is still a bit behind some dd driver iems.

Drivability and synergy

Trn VX is very easy to play with smartphone, bluetooth adapter, or dedicated dap.
When going outside, I use trn vx with trn bt20s. The combo sounds surprisingly good and is not in my way when doing exercises or public commute.
some friends wonder what cable to use pure silver or copper, so why not cableless.
Trn vx pairs very well with warm dap like sony zx300 or bluetooth receiver like earstudio es100 but when pairs with bright dap like my fiio x3 mark ii, I recommend turning down 3db at 2k,4k and 8k in the equalizer. In addition, if you use third music app for your phone, I highly recommend Poweramp music player app. It synergies well with the trn vx.

Songs that I used

Let Me Love You by Justin Bieber
Hang to Your Love by Sade
If You Wanna Be Good, You Gotta Be Bad by Bryan Adams
A Million Reasons by Lady Gaga
Bring Me to Life by Evanescence

Gear

Sony zx300
Hidisz ap80
Trn bt20s connect with smart phone using Poweramp

To sum up

This Trn newest Flagship, it is quite unique in this competitive market. You can not stand it or you absolutely admire their bold tuning. For friends who refer a more laid back in arm chair iems, looks elsewhere. But if you like resolution or you are one of those treble heard for this price range trn vx is outstanding.

Why do you write everything in bold. I got new glasses, thanks.
Pros: Excellent detail resolution; superb build.
Cons: Glassy/attenuated lower midrange; overly boosted upper midrange fatiguing for some; lifted shell design.

@scocth the KBEAR Diamond and TRN VX are polar opposites.

TRN VX is much better in technicalities (imaging, soundstage, clarity, details, instrument separation), whereas the KBEAR Diamond is much smoother, with poorer technicalities but better tonality and timbre. So depends what u prefer in your music.

TRN VX though, is pretty bright on the treble/upper mids area, so not the best for treble sensitive folks unless u wanna EQ or do some mods (see review). KBEAR Diamond is much more non fatiguing and better for chill sessions.
 
@baskingshark thank you so much, appreciate for your explanation. i have kbear diamond i'm listening house pop techno music (digital synth) with it. but i 'm looking alternative iem for metal, rock jazz (rich analog instrumental music, bright treble and instrument seperation needed music). i have rock it r50 for these genre. but i'm looking iem better than rock-it r50. ( my rock it r50 was 8 years old and i feeling that sound quality weakened over time, I can't get the taste I got at the beginning)

i have two alternative trn ba5 and trn vx. but ba5 is 38 dollar, trn vx 72 is dollar. 34 dollar is quite. do you think 34 dollar worth it?
or do you have any recommendation alternative these?
 
@scocth I don't have the BA5, but it has very good reviews so far on headfi.

If u look at this post, there's a comparison of graphs between BA5 and VX: https://www.head-fi.org/threads/trn-impressions-thread.881761/page-146#post-15638167

Most of my friends that use the BA5 said its bass is very fast and is suited for metal, though I haven't heard that to verify. There's a new CCA (parent company is KZ), called CCA CA16 that also just came out, it is a multi driver set like the TRN VX, but appears to be maybe $20 cheaper, u can check out some reviews on that too.
