I haven’t bought anything from Sony since the root kit fiasco.

By wired do you mean exclusively RCA or do you count usb as well? Both pair of my Sennheisers work via USB if you plug it in.

I’ve been using wifi on Linux since the ndiswrapper days. I haven’t had a wifi issue in many many years using Lenovo, Dell, Panasonic laptops and various self built servers (but they tend to be wired)
