“amazingly similar to originals in their sound quality”
I am amazingly similar to George Clooney. Hugh chunks of my DNA are identical, my internal organs are situated in the same locations, I have the same number of arms and legs, and I walk upright. Our hair color is even similar.
Yet apparently the few small differences that remain between us somehow keep millions of women from fawning over me.
Apparently ‘similar’ is not ‘same”.
I deeply doubt they are hiding behind this kind of strawman technicality, but are using “amazingly similar” in the sense that if you were thus to George Clooney, you could be credibly cast for him in a movie or play.
