The sound quality is the same if not better than the Pro 2s as far as I can tell. Not sure about the reviews you have been watching.Ordered mine after trading the pro 2 in at CEX. After watching some reviews on the poorer sound quality I was not going to bother but I never listen to music on them anyway, only podcasts and books. The feature I most wanted was the fitness/heart tracking so I can go back to a garmin from my apple watch.
