I got my AirPods Pro 3 the other day and finally got around to using them on today's walk (it's been very cold here). Anyway, my first impression is that there's more bass. I guess that's good but I'm not a heavy bass guy. Unfortunately, at the same time, it sounds like I've lost midrange and treble. Things sound "flat" and "muddy". The EQ app settings on the phone are presets and none of them sound great, just good. I wonder why Apple doesn't have manual settings here. I'll need to do some "side by side" comparisons with my APP1 to have a fair comparison.
I think the automatic conversation music attenuation feature may be useful. Whenever I encounter another person to say "good morning" or "hi" I always have to reach to stop the music. Maybe now I don't have to. On the other hand, if there's nobody around, I sometimes sing along so that won't work well.
The setup offered a Hearing Test but I couldn't get it to work. It kept asking me to put the pods in the case even though they were there already. Probably just a fluke.
Overall with the "out of the box" experience I'm fairly underwhelmed. But to be fair I'll need to do some more use and testing.
