If Bose does I’m unaware of it. Then again I never turn that kind of function on if I am aware of it.

Sony. Nope. It can be activated with a press, though never use it.

more like a dedicated assistant button than wake-word I think

I use an Anker Soundcore, and it doesn’t. Not exactly premium, but I like it.

I think my Jabra are considered premium as well. And they do not.
