The previous NW-A100 and NW-ZX500 Walkmans never received any Android updates, only security patches. Whether this was related to the SoC is unknown, but this is my suspicion. The new models are on Qualcomm SoCs which should have better Android support.
We finally have a full teardown of the Sony WH-1000XM5 from 52Audio.com, you can find the full teardown here. While this is not a full dismantling like I want to do in the future, it is better than my FCC teardown analysis. So time to dive in.
Sony's new WF-1000XM5 flagship earbuds are discounted around 17-19% on Amazon right now. I suspect this is a back to school deal. Although there is no discount in the UK, and the German price is only about 6% lower.
