Well the woman on the main team was just suspended, so she doesn’t really count! /s

You can use Nikon F lenses (and most other SLR mounts) on mirrorless cameras with a cheap adapter, so if we’re counting old lenses any mirrorless has significantly more options.

I don’t know about BIFL, but Audio Technica ATH-M50x are pretty good quality in my experience. I have the wired version (~$150) but they have a Bluetooth/wired version for $200. I did end up replacing the ear cups with something more comfortable for extended use though.
