I have a silver Jansport that is probably a decade old now and is still used 3 times a week or more for work, as well as used for airplane travel.
I'm about to look into having the large zipper repaired (it still zips, but I just have to make sure it's aligned now), rather than buying a new one. Best backpack I've ever had
Shokz (Aftershokz rebranded) are fantastic for endless online meetings if you're working remotely. I often forget I have them on. I did a whole set of in-person job interviews with them on before I realized I was wearing them at the end of the last interview.
It's pretty much the convenience and comfort of using external speakers, but without anyone else hearing. It's just a shame the audio quality isn't high-end for music.
