I've since taken some Craftsy classes. I even found one that had a written transcript with it as the instructor talked.
All of the classes should have that. There are people who are hard of hearing at any age and some devices can be annoying with earphones. I had a tablet that cut the volume as soon as the earphone jack was used. Said to keep the device from allowing "loud music".
We aren't listening to loud music, but an instructor who often talks while stitching on the machine so turning up the volume isn't damaging. ( there was an override, but try to find it)
My cat gets tangled in the earphones if I use my laptop.
