I think by now Mr. Crin has already a dozen colabs out to know what was a safe bet and what was risk taking. AFAIK budget IEMs need to be produced in large batches (think thousands at a time), so tuning, fit and finish need to be perfect to avoid losing money. And in this range (<50 USD) is where his genius shines the most IMO (admitted fanboy here).
Crin was the guy that companies sent IEM prototypes and early units hoping for a favourable review. Then they hired him for consulting and marketing (colabs). Now we reached the final stage: his name stands alone on the brand... By definition his approval was done in all details. How cool is that for a success story?

(his Hangout store is by definition only "curated, Crinacle approved IEMs", using his approval as a seal of "satisfaction guarantee")
This is a marketing masterclass happening before our eyes. Like the Steve Jobs creating the Apple empire, limited to the IEM industry, not by inventing new things, but just by merging SOTA research and tech with tasteful balancing of products. Hopefully he stops there and doesn't get greedy as Apple turned out lol.
