Thought I’d post a follow-up…
I happened to notice today that I had enabled the iOS Headphone Safety feature to Reduce Loud Sounds.
Once I disabled it (or even raised the limit higher), the Wyze Headphones sounded better, and the distortion was gone.
It’s weird that with the previous setting, it didn’t affect my Sony WH-1000XM4 or AirPods Max and only the Wyze Headphones, but perhaps that will help someone out.
So, now I would say the Wyze Headphones meet or maybe slightly exceed expectations. No, I wouldn’t expect them to match the Sony or Apple headphones, but the noise cancellation works pretty good and the sound signature is above average.
