Updates are good. New models are not. Additional products should be released with careful consideration because every time a customer has to decide which one to get they increase the risk they won't get any of them. So AirPod vs AirPod Pro makes sense with the improved audio and noise cancellation in the later. But if you are going to introduce over the ear headphones you gotta kill one of the other products.
But wait... you may say... choice is good. More choices are better than less.
No. No they are not.
