Awesome video Ron, thank you! One observation, though. When I hear you super impressed with the Central AC, Planes, Birds, and Traffic being cancelled out with the 4 Pro, and you rate them often like other buds that you really like, at a 7.5, realize that a 7.5 is like a 75% in grading. That's a C Grade, which is average. I never got praise of Wonderful, Fantastic, or Stoked from a parent or teacher with a C grade, lol. Something that is above average should be at least 8 - 8.5, I feel. I've seen this in multiple reviews, and again, it's just an observation. 7.5, in a grading perspective, is just Ok/Acceptable/Fair. Your description and passion don't match your scoring. Food for thought, my friend! Stay blessed.
I think they did a great job with noise cancelling. I wasn't even using my perfered eartips. They're not on the Bose/Sony/AirPods level but they are really good.
