Sure thing. I have a lot of headphones :) Re: the A50, I had to remove the centerpiece foam because it caused headaches pressing into the top of my skull, and so now there's a towel wrapped around them to provide less-but-some padding. If it weren't for that, they'd be perfect for their use case. The Beats Studio3 fit perfectly at maximum extension, as do the DT770s and the old Sony Gold headsets. I had to return the Sony Platinum headset for being too small, because they chose to shrink it slightly for wider compatibility and I no longer fit their line.

The most likely (90%) cause of having to give up and return AirPods Pro Max will be if they can't fit over my annoying skull. Second most likely (10%), they end up weighing too much. We'll see!
