I am not denying the growth. My observation was that based on the fact that most Apple customers who wanted Apple wireless earbuds already had them, the high demand for Pro earbuds is somewhat surprising. And I attribute it to two factors:
* Apple customers were not as satisfied with old design as they seemed, which was a somewhat strange phenomena because basically all quality earbuds manufacturers, except for Apple, were using sealing (in-ear) design. Are Apple customers that different from other people when it comes to headphones? I do not think so.
* There is always some demand for a new Apple product (especially if it is released right before the holidays). That's a default (sometimes lazy) gift option for many. Also, some people have to have all Apple gadgets.
So, I think once again Apple did double dipping: first sold an inferior design to their customers and then came up with a new incarnation.
