Because I did the Destiny Quest lesson with all 540 students at OMS I was able to get a lot of feedback on what they liked and didn't like about these video tutorials. I'll be posting some of their comments later in more detail, but many of them didn't like the sound quality of our lab headphones. Our computers are around 5 years old, and the sound quality leaves something to be desired. Perhaps the headphone jacks on some were scratchy from years of plugging and unplugging, the cords of the headphones damaged, etc. Instructional time was lost for some students when they had to swap out their headphones for another pair, or we had to troubleshoot other sound issues.
I went ahead and invested in a class set of USB headsets, and the sound has been much improved. They were around $20-22 per pair, but it's been worth it.
