The Headphones Connect app is primarily designed for wireless headphones, so I think it'll happen eventually, might just be that it's a new release. It's probably a good idea to stay tuned using their support app though, it's called Support by Sony, It's always included at the bottom of their device support page, here's the link if you need it: https://www.sony.co.uk/electronics/support/articles/00204426?cpint=spt-subfooter_sbs
