Question: AirPods Max Connecting to iPhone and PC Simultaneously

My apologies if this is not the right place or way to ask this. Please steer me to the right place if this is not.

I am considering buying new over-the-ear headphones that allow me to connect to my iPhone (a pretty recent model) and my PC via bluetooth at the same time.

Is this possible and are people doing this sucesfully?

If anyone is curious there is some more background below, but my question is a simple one, I think.

I currently have a pair of Seinheiser Momentum 3 headphones that can connect to both simultaneously, but I pretty much hate them. Not only is their bluetooth implementation a little shaky at times, but the headphones themselves get uncomfortable after a couple of hours.

I am considering picking up a pair of the later Max headphones since I have never been let down by Apple's headphone products, but I would like to make sure that this can work before investing the money.
