I can't read the article but I am guessing he is saying they are the best "wireless earbuds" and how many truly wireless ones have you tried? Because truly wireless earbuds there are only a handful of options out there so being the best of 5 or whatever it might be isn't really that great of an accomplishment.

But if the article takes into consideration of ones where the buds are connected to each other by a wire then that is different.
