I have a pair of AirPods Pro 2 that I wear every day during my commute to quiet the sounds of the bus and subway. Santa brought me an upgraded Pro 3 set last week. Noise cancellation in the Pro 2 was very good. ANC in the Pro 3 is astonishing. The normal background of a thumping diesel engine behind my head went from a quieted roar to nearly silent.
If you love your Pro 2s, which you should, because they’re great, then stick with them. If you were looking for an excuse to upgrade, this is me telling you to do it.
