I am looking for a Lot (many ~20 or so) of old school headphones the ones that look retro because they are. I know there a bins of these things laying around in closets, but I haven't found any so let me know if you have some or stumble across them. I am not looking to spend that much and I would much rather recycle some old ones that buy new.

I want to make them in to electric field detectors (don't worry it will be cool)

I've got a 70's-era set of Koss cans, but I still use 'em.

They had some at the Pavek broadcast museum garage sale a little while ago, maybe you could contact them.

Bam!!!

I hope this pans out...contacting Pavek now

I want to do something similar to this

I emailed back and forth with the people over there and I came to the conclusion that I am just going to have to stop by some time and take a look.

It's worth the visit in any case.
