I use them with my Pixel 5. They work fine. No spatial audio and no battery status for the case or headphones. You can get apps that unreliably show that info but they require excessive permissions and are loaded with ads. Occasionally the headphones won't connect or one headphone won't play audio. Toggling bluetooth or rebooting my phone is usually required at that point.

I got mine in February 2021, I would say that connection issues have improved since then through a couple firmware updates. But you can only install the firmware updates if you have an iphone/ipad/mac so thats another barrier.
