There's only 2 readers. Kate Redding does (most) of the female PoVs, and Michael Kramer does (most) of the male PoVs. Sometimes there's small PoVs in a predominately opposite gender section, and the one who did the majority will also cover the small one.
I may be misspelling those names btw.
Regardless, I feel that they do very well all throughout, and tbh I enjoyed the BS books better listening to them than I did reading through them, as their voices really helped keep things consistent.
