I noticed this is a bone of contention among the HN community. It is clear why: both wired and wireless headphones have their advantages and inherent problems that had been discussed ad nauseam. In general, there is no problem as we are free people able to choose what we want and need. The problem appears when a company with a dominant position in the market declares one of these technologies dead and pushes their users towards the other one.
It's not just wireless audio. The same happened with the Ethernet: while most people use WiFi, Ethernet (especially Gigabit and faster) also has its advantages. Removing an Ethernet port is not an improvement: it is a statement.
