Introduction
The VX is the new flagship model from TRN and is their most ambitious design to date. It is a hybrid IEM featuring 7 drivers per channel (1DD + 6BA). It enters a competitive market with CCA's CA16 (1 DD + 7BA) and the CSN from CVJ (1 DD + 5BA) also being recent rivals. The dynamic driver is a dual magnet unit with a 10mm diaphragm. Three 50060 BAs are employed for the midrange and three 30095 armatures cover the treble, with two of these placed within the nozzle.

Description
The VX comes in traditional TRN packaging, a small rectangular box similar to that used by KZ and CCA. There is a red TRN logo and an outline image of the IEMs on the front and specifications on the back. Sliding off the cover reveals the earpieces set in a card cut-out, under which you will find the 2-pin cable, two sets of black silicone eartips with a medium red-coloured bore (the medium size is pre-fitted) and documentation. At $75 this basic presentation was disappointing for a top of the range model and is very similar to that supplied with the $15 ST1. KBEAR's Diamond at approximately the same price as the VX comes in sumptuous packaging and includes a quality case and accessories.

The earpieces are very well made from CNC machined magnesium alloy. They are attractively contoured, with the face featuring three radiating sculpted lines and are somewhat shell-like (pun intended). My particular sample was finished in an attractive dark metallic green and looked very stylish. It is also available in "Knight Black". There are two small vents on the inner surface and the legend "VX DDx1 BAx6" is written on the top edge and there is channel identification on the inner surface. The nozzles are black and have a silver mesh grille.

The cable is a black 4-core braided type with QDC connectors and is similar to that supplied with the BA5 and V90, being terminated by a straight 3.5mm plug bearing a white TRN logo. There is a metal Y-split but no chin slider and the cable is prone to tangling.

First Impressions
The earphones were auditioned using a variety of sources, primarily a Sony NWZ-A15 DAP. I found the sound with my Xduoo X20 unsuitable as its clean and neutral character compounded the bright nature of the VX. I also used a Huawei smartphone and a CD player during testing. After a burn-in period of 100 hours was carried out, I began my evaluation.

In stock form, the sound was bright, both in the mids, which were forward, and in the treble, which was clean and incisive. Along with a tight, fast bass with a cool tonality, this produced an exciting and detailed sound with extreme clarity, but emphased the high frequencies. I am not particularly treble-sensitive and enjoyed the detail and precision on offer, but the overall balance was a little too treble-focused. Changing the tips to KZ Starlines improved the balance with the bass being warmer and deeper and the top end smoothed out a little, without losing the excellent detail and resolution. Having tested the supplied cable with the CCA CA16 I found that too sounded bright so replaced it with a Senlee hybrid cable. This brought things more into balance and this was the configuration used for testing. Used like this, they were light and comfortable to wear and isolation was good. Sensitivity was good on all sources, being far more easily driven than the CCA CA16, for example.

Bass
The VX's bass displayed superb resolution and definition, each note being reproduced with precision and impressive transient attack, and free of overhang. The focus was on the sub-bass with mid-bass more reserved. The general level of the bass was a little light compared to the CA16 and CVJ CSN and could benefit from some augmentation.

Davol's "Another Land" from the album "Paradox" begins with deep bass synthesiser. Accompanied by electronic and percussive elements, the reverberant effects were very powerful and effective. The deep string synth parts later in the piece displayed excellent texture.

"In Church" from Viteslav Novak's "Slovak Suite" features a prominent part for organ. The firm and resonant timbre of the pedal notes was very well presented and formed a perfect backdrop for the cascading strings and harp accompaniment by the RLPO under Libor Pesek. A little more depth would have been welcome here to give the organ more weight.

The texture and timbre of the bass guitar in Bob Marley's "One Love" came over very well. This fell just in the VX's sweet spot of the lower bass and sounded perfectly balanced with the drums and vocals. The clarity here once more showed its quality with everything being in sharp focus.

Midrange
The midrange was slightly forward and somewhat brighter than neutral. With an absence of bass bleed, this emphasised the detail and provided a clean and open sound enabling individual instruments to be pinpointed. Occasionally I found myself wishing for a little more warmth.

In Frank Bridge's beautiful tone poem "There is a Willow grows aslant a Brook" the character of each concertante instrument was clearly depicted. Clarinet, cello, flute and bassoon all stood out clearly from the accompaniment thanks to the excellent clarity and separation. The ambience of the recording venue was particularly well-rendered.

ABBA's "Slipping through my fingers" has a lead vocal by Agnetha and the character of her clear voice came over very authentically and was nicely highlighted over the guitar and synth production. The lyrics in the backing vocals were clearly audible. Via the sound of a ticking clock, this track then segues into "Like an Angel passing through my room" which features vocals by Annifrid. The husky quality of her contralto voice was most noticeable in the intimate acoustic and the classical-style synth chords in the middle section sounded beautiful. The different qualities of the girls' voices were well differentiated.

The solo cello in "The Cold Sea's Embrace" from "So flows the Current" by Patrick O'Hearn displayed excellent timbre with just the right amount of "bite". Set against a deep plucked bass, it produced an almost 3-D effect which threw the solo instrument into clear focus with the moody atmosphere of the piece perfectly preserved.

Treble
The treble was somewhat brighter than neutral but at the same time full of detail and energy. Micro-detail was class-leading.
This came to the fore in "Dreams of Fair Women" by Canadian synth duo Exchange. The arpeggiated guitar accompaniment was clean and clear and the high synth accents beautifully etched. The sense of openness was palpable.

Bach's Brandenburg Concerto No. 4 performed by the Saar Chamber Orchestra showcased alto recorder with harpsichord and string continuo. The solo instrument was clearly defined with the VX's bright timbre suiting the harpsichord and flute parts very well. The rhythmic nature of the piece was excitingly portrayed.

"I Robot", the title track from the Alan Parsons Project album begins with a bass drone and wordless female vocals. Next comes a sequenced synth bass line and percussion. Guitars and choral effects join in and a resonant cimbalom solo plays over the top. Everything remained clear and separate with the sharp tones of the solo instrument clearly focused above the complex production.

Soundstage
The VX produced a large stage which was oval in shape, being wider than deep and with a decent impression of height. Due to the bright tonality, positioning of instruments within the image was very precise with layering and separation defects very well-defined.

Hamish McCunn's "Land of the Mountain and Flood" is an orchestral evocation of the Scottish landscape. In the version by the BBC Scottish Symphony the orchestra was laid out most convincingly. As horn, oboe and brass quoted parts of the main theme it was easy to discern their various locations within the image.

"Beautiful Attractor" is an electronic piece by Robert Carty from his album "In Neptune's Wake". Swirling electronic effects and crystalline percussive elements populated the stage, while other effects circled around it. The meandering synth lead was supported by a richly-textured bass drone and all was placed within a wonderfully spacious acoustic. This was a perfect piece for the VX, and highlighted its best qualities.

"You Raise me Up" in the original version by Secret Garden features a beautiful violin solo by Fionnula Sherry and an expressive lead vocal by Brian Kennedy. It was clearly reproduced and placed within a resonant acoustic. In the central part he is accompanied by the Irish choir Anuna. Bolstered by full orchestra and Uilleann pipes, the whole effect was breathtaking and filled all the available space in the stage. The conclusion returned to the intimate solo vocal and was full of emotion.

Conclusion
For some time the Chi-fi multi-driver roost has been ruled by KZ's ZSX and ZS7 and the CCA C12. It has now been supplanted by a new triumvirate of the CCA CA16, the CSN from CVJ and now, the TRN VX. Which is best very much depends on your sound preference. The CSN is the most neutral of the three with a linear bass, slightly forward mids and an extended, clean treble. The tonality is slightly cool. The CA16 is warmer in tone and has a mild U or V shape. The midrange timbre is excellent and the treble is silky and open. Bass is deep and well-resolved from the new 7mm driver.

The VX in stock form is noticeably bright but this can be addressed with a change of tips and cable, and a warm source is recommended. Most of us have some Starline tips and a cable or two knocking about so there need not be too much additional expense.

Thus equipped, the VX delivers an impressive combination of clarity, resolution, speed and detail which is very exciting and entertaining. Although a bit bass-light, I found the VX's sound very addictive and especially effective with electronic music. It is closer to the CVJ CSN in tonality but brighter and with a little less bass, while the CCA CA16 is darker, more natural and more relaxed. Although a little more expensive than its competitors the VX does offer a different presentation and if you value detail, focus and resolution, it represents an interesting alternative and stands out from the host of similar-sounding models on the market. I have dubbed it "The Green Monster" after Art Arfons's land speed record breaking car: fast, powerful and exciting!

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.

Comments

@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.
