Will never buy any type but that from now on. So I decided to look online, and found them at Amazon. The product did fit a little tight, I could have gone up one more x. Maybe just that one was made wrong. Comparisons:CCA-C10 ($46) vs TRN-V80 ($39):The TRN is one of the latest flavor of the months, and the hype or attention is warranted. I am referring for the old version. He wears a 9. They sound similar to my airpod pros - at the same price with less function (water resistant, mobility, etc). Surely this would work as it should. I have a medium width foot.
