Why would I want to replace the headphones I am using for a decade with something I have to replace every few years. Its already sad enough that I have to replace my phone every year or two because of its battery and software upgrades that slow it down.
You can now add headphones to your upgrade cycles because number of new phones with reasonable specs and wired headphone support are becoming rare.
If this proves cost effective to manufacture and resulting headphones come with inbuilt obsolescence due to batteries and degrading rubber, we'll see manufacturers aggressively pushing this new technology.
