I posted this in another thread since there were some talk about the Vx there but since it's actually more relevant here I drop it here as well.
After having the TRN Vx for a couple of days I honestly feel that it's getting bashed a bit unfairly. Sure the upper frequencies are on the splashy and sibilant side but the bass is fantastic on them imo. Right from the first listening session they got me thinking about the NX7 and today I spent some time comparing the two (and the NX7 Pro as well).
The sort impressions from the comparisons with the original NX7 is that overall tonality is indeed very similar. For me the Vx does actually has a touch
less tiresome higher frequencies, midrange quality is very similar but more forward on the Vx. When it comes to bass the quality is great on both imo but it hits harder on the Vx. Personally (and so far, I still have only got a few days with the Vx) I'd take the Vx over the NX7. Although none of these two will ever become my favorite IEM's the NX7 was hyped pretty hard when it was first released while the Vx has received the opposite treatment. That's the reason I'd like to share my thoughts, I think often the first impressions of an new item will set preference for many later impressions.
When it comes to the NX7 Pro I think I'd take it over the Vx because of a bit welcome added warmth in the upper frequencies. Everything else is at least as good on the Vx imo.
Now I'm looking forward to the NX7 mk III release
For the record I purchased the Vx myself and it took exactly three months for it to arrive
Enough time for a product that's not top notch in enough aspects to become obsolete these days, that says quite a bit about the speed of progress today.
