Are you guessing on the 500ms? Looks like the most recent AirPods Pro can achieve 144ms [0], so I'd imagine the Max to be slightly less.

Not great, but should allow phone conversations without too much fatigue.

I didn't realize the latency on AirPods was that bad. That actually explains a lot of the difficulties I have with phone calls on them. (One of my hats is "audio engineer", and two people on AirPods plus transmission delay has to get up into the 350-450ms range, and that definitely is fatiguing given that my ears are always cued to this.)

Back to holding my phone against my face, I guess.

Yeah, this is crazy that Apple is only using AAC for their codec and not anything like aptX that can get down to 50ms range. I would expect Apple to do better here and even have different low latency codec specifically for voice calls.

What about using wired earbuds with a Lightning dongle? That should give low latency, right?

Yep, they made up that 500ms number.
