I think the AirPods Pro ANC is very good however, I have the Bose QC35 and Sony WH1000XM3 over ear ANC headphones. Do to them I was kind of unrealistically expecting more out of the APP’s ANC and was initially somewhat disappointed. I have accepted the fact that in ear buds can’t block noise as well as over ear headphones. I originally bought them so I could stream video on my iPad while my wife watches the TV. For that they work perfectly. I originally bought the Sony WF1000MX3 in ear buds because, the ANC and sound is noticeably better than APP’s. I returned them because, they didn’t stay in my ears well and weren’t as comfortable as APP’s. Over all, my APP’s are great and I will keep them. They are comfortable, sound good, ANC works and they work seamlessly with all my Apple devices. If I need more ANC I pop on my over ear headphones.
