Available Colors: Dark Green, Knight Black, Vibrant Blue (haven’t seen this color anywhere though)
In The Box: Earpiece, cable and 3 pairs of eartips (S/M/L)
Packaging and Accessories: The packaging and accessories are underwhelming given other IEMs in the same price range (like the KBEAR Diamond, for example) but I’m guessing that’s the price you pay for having more drivers. The cable is also very basic and apart from having a different plug and connectors, it feels exactly like the one that comes with Blon BL-03, with the stiff memory hooks that make it prone to tangling. The stock eartips are not bad and work well for me.
Earpiece Build and Design: Really good build quality and quite a looker (subjective).
Driver Flex: I rarely experience driver flex on the VX.
Cable Noise: The VX is designed to be worn over the ears so you don’t get any cable noise.
Comfort and Fit: The VX fits very well on my ears, is light and very comfortable (Note: This is very relative to your specific ear shape)
Isolation: Fits very snugly in my ears so isolation is good for me. With music on, I can barely hear what’s going on around me.
Efficiency: Easy to drive with most smartphones and doesn’t require an amp.
Chain: (Phone|Laptop) > Spotify Premium (Downloaded, Quality: Very High) > Meizu Hifi Pro DAC > IEM
TRV VX: Stock cable and eartips
Reference: Etymotic ER2XR with stock triple flange regular tips.
Tonality & Technicalities
To me, it sounds like the bass is boosted but not as much as the upper-mids and treble, and the lower-mids are slightly recessed. It doesn’t sound as coherent as single-DD IEMs and the bass can sound disjoint from the rest of the range.
Bass is boosted but not too much and well extended. It’s fast and pretty linear with no sign of boominess or bass-bleed. While I prefer the sub-bass focus, it might not be a very natural presentation. Drums and bass guitars sound a little muted and the upper harmonic focus doesn’t lend itself to a very organic sound.
The lower-mids are slightly recessed while the upper-mids are substantially boosted and the midrange has a very forward and detailed presentation. The cut in the lower-mids makes instruments and vocals that have their fundamental in that area sound thin. The substantial boost in the upper-mids results in instruments like electric guitars sounding a little shrill/aggressive. On some tracks with female vocals, I really like/enjoy the wet presentation as it adds a visceral dimension to the voice.
Treble is boosted, aggressive, detailed and decently extended. The emphasis in this area coupled with the faster BA decay, can make instruments sound unnatural but also results in more clarity and detail. The treble boost makes certain instruments standout in the mix in an unnatural way, which can make some tracks interesting and not so much for others. It can be borderline siblant but I don’t think it crosses over to being siblant. Cymbal strikes are splashy and not as harmonically rich and resolving.
Soundstage, Seperation and Imaging
Soundstage is out-of-the-head both in width and depth with decent separation and imaging. However, the sense of space is not realistic. A performance in a theater doesn’t sound like it’s in a theater. I suspect this is because of the spikes in the treble region.
The TRN VX can be a fun/aggressive/analytical sounding IEM that trebleheads might enjoy. The upper-mids and treble boost will most likely be harsh and fatiguing, especially for people that are sensitive to that area. Those who enjoy the coherency of a single-DD may find the bass disjoint from the rest of the range.
