TRN VX PRO Chifi IEMs – Brightest Shape Of Metal

TRN VX PRO Chifi IEMs – Brightest Shape Of Metal

TRN VX PRO is a 9 Driver Entry-level IEM priced at 88 USD. They made a hybrid design, and gave VX PRO one dynamic driver, and 8 Balanced Armatures. It will be compared with Tin Hifi T3 Plus (70 USD), HIDIZS MS2 Rainbow (90 USD), and CCA CKX (70 USD). 



TRN Audio or TRN Hifi is a really interesting company from China, who created the first IEM that electrocuted me in the ears, at a literal level. They evolved a ton since then, and their current offer includes many popular entry-level choices, but I recommend considering Linsoul as your main source for Chifi stuff rather than purchasing it directly from Aliexpress. Linsoul helps you with the shipping, customs, and repair process, and they provide support in every step along the way, being much more reliable than purchasing randomly off Aliexpress. Linsoul also has much lower shipping times than most Aliexpress packages, and I’m still waiting for products I ordered from Ali months ago, while Linsoul shipped and delivered VX PRO to me in less than a week. Linsoul also has cheaper prices than the original stores most of the time, and they are available on Amazon as well, being the main gateway pusher of Chifi products to the west. 

It should be noted that I have absolutely no affiliation with Linsoul or TRN Hifi, I am not receiving any incentive for this review or to sweeten things out. I’d like to thank Linsoul for providing the sample for this review. Every opinion expressed is mine and I stand by it. The purpose of this review is to help those interested in TRN VX PRO find their next music companion.

First things first, let’s get the packaging out of the way:

The package of TRN VX PRO is actually impressive, and they come with a metallic carrying case, similar to the one HIFIMAN ships their RE2000 and RE2000 Silver IEMS in. There is also a good collection of tips, including two types of silicone tips, each in three pairs, one pair of foam tips, and one adapter from 3.5mm to 6.3mm. 


Build Quality/Aesthetics/Fit/Comfort

Someone actually asked me today how is it possible that VX PRO has 9 drivers per ear, but then I sat and said, many drivers do not equal strong or detailed sound. Many drivers are just many drivers. We have a good configuration though, with one CNT or Carbon NanoTube Dynamic Driver, and eight Balanced Armatures per each ear. This is impressive, even as a statement, as for the 88 USD price of the IEM, we need to assume that the package is at least 10 USD, cable is at least 15 USD, which means that the drivers cost at most 31 USD per IEM, which would mean a driver cost of at most 3 USD per driver. Of course, using Belsing drivers, it is possible to find even more affordable ones, but the question is how will it sound, rather than what is inside. 

The outer shell of VX PRO is made from aluminum, in a five axis high-precision CNC machine, and you can see how all edges match perfectly and the IEMs are made like a flagship. There’s no electric leakage this time around, and using VX PRO is a pleasure. The cable is a 4-Core Silver-Plated Copper Cable, a good build quality. It is not tangle prone, the cable is well made, and does not carry microphonic noise at all, being slightly soft rather than hard and springy. The cable is detachable, and based on the 2-Pin reversed connector, a popular connector for entry level products, especially Chifi IEMs. 

We have a rather low impedance on VX PRO, at 22 OHMs, which is pretty good, but the somewhat lower sensitivity of 106dB means that they won’t be that easy to drive, but will be somewhat sensitive to hiss. In fact, I can hear hissing even with high-end DAPs, like iBasso DX240, using their AMP8 MK2 module, but cannot hear any hissing with Astell & Kern SE180. There are two color options, and I am happy to have received the Moonshine Silver variant, it is the more beautiful one. 

If you look on Linsoul, or other websites (TRN Hifi does not seem to have a website of their own), the driver arrangement looks more like a gatling gun than a driver configuration for an IEM. As TRN states, there are 18 drivers working together to satisfy your hifi Fantasy. 

Now to the comfort of TRN VX PRO, they are mostly comfortable. The IEM shells are large, the bore is large, and I can totally feel them, plus the IEM shells are on the heavy and bulky side. The design is really ergonomic and has no edges, but won’t work for small ears. 

The ear hook cable part is really tight, but it is soft and made of silicone, so it won’t bother you. They isolate extremely well from the outside noise, with about 20 and up to 30 dB of passive noise isolation, and even with quiet music playing I was unable to hear my gf screaming at me from right next to me (she’s working on editing more Audiophile-Heaven Videos, God Bless Her). VX PRO does leak somewhat to others, and even quiet music is audible to others while wearing them. You can feel the dynamic driver while inserting them, but you can’t hear any distortion and it won’t flex too much. 


Sound Quality

The overall sound of VX PRO can be described as rich, detailed, fun, engaging, V-Shaped with a strong bottom end and a very strong, bright treble, textured presentation, and fairly good instrument separation / imaging. For driving them during today’s review, I have been using iBasso DX240 with AMP8 MK2, Astell & Kern SE180, Lotoo PAW6000, and Dethonray DTR1+ Prelude

The bass of TRN VX PRO is clean, deep, and rolls off at about 40 Hz, in a gentle fashion. Most of its energy is between 40 Hz and 80 Hz, having a thumpy and impactful presentation, with a good body and good strength. There’s no upper bass elevation that bleeds in the midrange, which is nice to see, but the bass to treble ratio is a bit low, causing the whole signature and tuning to be somewhat bright. I find it ideal to listen to VX PRO while at home and sitting in my chair, writing reviews, but for outdoor walks, they are a bit bright and lack lows for my ears. The bass has a natural speed, not very nuanced presentation, making all bass notes sound similar, but has good presence when it is called for, and doesn’t roll off from Metal, Rock and Punk music, for example Attack Attack – Stick Stickly, the Crab Song having a really impressive bottom end that can be heard as low as 40 Hz during the intro of the song. The same song continues having a really bright and detailed presentation of textures, and a clean overall tuning to it. 

The midrange of VX PRO is also clean, fun and detailed, with excellent overall width, and average depth. The midrange is somewhat crispy, with tons of textures, and has a really clean presentation, edging on being clinical at times, having a rather low amount of thickness and body. The midrange has a bright tuning, with an analytical edge that brings all details forward, focusing more on how detailed sound can be rather than musicality and smoothness. VX PRO is great for discovering macro details in music, especially rock, metal and Electronic music. On songs like Shiki – Bowsette, I can hear a really nice vocal presentation, and the piano effects playing far in the background. The bass focus is great, and the song has a nice weight / impact. Instrument separation is superb, and detail is nice too. The treble is quite bright, and all effects / drums have a tss sound that’s emphasized. 

The treble of VX PRO is where most of their energy is, as they have a really open, sparkly, edging on too much treble. VX Pro has a ton of information in the upper registers, and presents music sharply, with good air and a wide stage. For example, on ChuggaBoom – Bohemian Rhapsody, all voices are slightly sibilant and harsh, and there’s a strong emphasis on cymbals and their energy, but that’s a peak focus, as not the entire treble is enhanced, but a 12-14kHz peak specifically. TRN VX PRO is plenty dynamic and for an enrttry-level IEM with many drivers, they have tons of dynamics, sounding superb with Linkin Park and NuMetal in general. 



TRN VX PRO vs Tin Hifi T3 Plus (88 USD vs 70 USD) – T3 Plus is smaller than VX PRO, also lighter, but VX PRo feels and looks better made, with a more quality construction, and a slightly better cable from the factory. The tuning is much warmer, thicker, much smoother on T3 Plus which is basically a basshead IEM with a natural sound, where VX PRO is considerably more detailed, more analytical, has a wider soundstage, more air in the treble and a much brighter tuning. 

TRN VX PRO vs HIDIZS Ms2 Rainbow (88 USD vs 90 USD) – MS2 Rainbow is lighter, more comfortable, but made of plastic and can feel a bit gimmicky in person, compared to VX PRO which feels better made but is larger and heavier. The overall signature is thicker, with more mid bass emphasis, a warmer presentation and it is smoother on Ms2 Rainbow from HDIZIS. By comparison, VX pro sounds more analytical, has more detail, brighter tuning, is more dynamic, and sounds more open, more airy, with a wider soundstage. 

TRN VX PRO vs CCA CKX (88 USD vs 70 USD) – CKX is actually very similar in tuning to VX PRO, but physically smaller and more comfortable. VX PRO has better build quality, at the cost of a larger build and higher weight. VX PRO is more detailed, but also brighter and more sparkly. I prefer the overall resolution of VX PRO for certain rock and metal, but the treble can get fatiguing quicker than the sound of CKX, which feels more natural. If you want to hear the most detail Chifi has to offer, at this exact price point, I recommend checking out VX PRO. 


Value and Conclusion

At the end of the day, when judging TRN VX PRO for their 88 USD price tag, they are an excellent deal. It is quite hard to find IEMs as detailed, clean and analytical around the price point. They have a nice soundstage too, plus a good amount of bass that doesn’t roll off too soon, considering the price. The comfort is fine too, and the build quality is superb. 

You won’t have to worry about warranty and having problems down the line if you decide to order from Linsoul, and they are one of the shops who offer excellent delivery times, support for their customers, along with some of the best deals ever seen. If you want to make things even better for you, I recommend checking their store on Amazon, as you’ll have the coverage of both Linsoul and Amazon

If you’re looking for a high-quality IEM with a nice build quality, tons of details, a nice build quality, good comfort, beautiful aesthetics, and a bright, vivid, analytical sound with good dynamics and a wide stage, for a pocket friendly price, TRN VX pro from Linsoul is an excellent choice.
