Apple's press release for the HomePod mini 2 last month touted "rich sound" and "advanced computational audio," but it did not explicitly mention if the second-generation model has better sound compared to the original. A few early reviews of the speaker, however, said that audio quality has in fact improved.

Apple's tech specs pages for both the HomePod mini 2 and the original HomePod mini mention a "full-range driver" and "dual passive radiators for deep bass and crisp high frequencies," so the core speaker hardware is seemingly unchanged. However, the HomePod mini 2 is equipped with a much newer S10 chip that could use advanced algorithms to optimize sound in an improved manner compared to the S5 chip in the original model.

CNET 's Tyler Lacoma said the HomePod mini 2 has "much better sound" than the original model.
