Being able to browse a multi-TB library from any device is pretty nice. After the PH purge disappeared many of my favourite links overnight I started taking collecting seriously. Also transcoding helps when away from home with a mobile internet connection. Before jellyfin I was using shitty hidden photo album phone apps to hold my collection
I haven’t used wired earphones or headphones in maybe 4 years now. No way I would go back to being tethered to my PC and/or dealing with tangled wires, especially with how well the newer versions of Bluetooth work.
