>Zeos has very similar tastes compared to mine.

This is a good way to follow reviewers in general, no disagreements there.

>I trust him more than any other reviewer.

I mean maybe consider re evaluating that trust honestly? I think he's entertaining and has some interesting vids sometimes sure. But at the end of the day he's more salesman than reviewer. He rarely publishes a negative review. I could explain more but there's a reason a majority of people in this sub and other more headphone focused subs tend to not use his reviews as a good "objective" viewpoint (although that isn't to say there is a reviewer out there who is purely objective, nor that pure objectivity is even desired).

Edit: Just to further clarify, relative to the more technical reviewers out there, and disregarding other criticisms of Zeos, he doesn't match that same level of technical info you get from someone like Super Review or Crin, but that doesn't mean one is necessarily better than the other.*

Either way I'd encourage you to search around here and other audio forums about zeos and/or other reviewers that could also line up with your preferences. Always good to find new reviewers whose preferences line up with yours!

>I should probably try one of the IEMs he "tuned", even if I suspect these are just branding collabs.

I say go for it and post your impressions if you feel like it!
