I teach an editing class, and I keep a spare set of headphones for students to use when they forget their own. I call them the "painphones". They went through the wash (don't ask how, it was after a long shoot...) and have lost most of the padding. They still work, but are fairly uncomfortable to wear. Even still, there is always at least one student who has forgotten to bring headphones and is willing to put up with the pain. I'm hoping these new headphones will bring a new level of shame to the process.
The only problem I see is when (in the inevitable future...) I forget my sennheiser headphones and have to use these on a professional shoot. I'll let you know how that works out.
