I've been using AirPods for several years now. I saw the AirPod Pro was on sale during Prime Day, and picked them up.
I can't say that I noticed a difference in sound quality between the regular and the Pro; certainly not enough to warrant the price difference.
Worse (for me) is that the Pro is huge; it's intended to fill the entire outer ear cavity. Unfortunately, the back of my right ear is bent in slightly; you wouldn't notice it by looking at it, because it really is slight. But it's enough to keep the Pro from staying secure in my right ear. It kept popping out.
And to make matters even worse... the stems on the Pro are much shorter, and have a button on them to turn noise cancellation on/off. So as I'm trying to get it to stay in my ear, I'm grabbing the stem and repeatedly pressing the button. So annoying; I would have preferred a longer stem to grasp.
I didn't even have the Pro for a day before I realized the fit issue was a non-starter, and I gave them to my wife. And I appreciate my regular AirPods so much more. Easy to grab, easy to slip in, and they stay in place. I really hope Apple keeps version 3 smaller than the Pro.
