That's not exactly true, unfortunately; because Apple's product line-up would be too easy to understand otherwise. Only the couple of first generations of Beats products after the acquisition have used the Apple-branded SoCs. The current line-up uses unnamed Beats-specific chip that has ~most (but not all!) of the same features as the W1/W2 on iOS. From the current line-up, only Powerbeats Pro (2019) and Beats Flex (2020) use Apple branded-chip, and I'm under the impression that the newer models have more Android-specific niceties. I would expect next refreshes of those Beats model to lose H1/W1/W2.
