PWB Headphones, any one hear of 'em?

There is not much known about them and in the 5 years of collecting electrostatic headphones I've only come across the transformer/adapter once so they are quite rare. I'd love to see some pictures of them.

180$ is a pretty steep price for something that not much is known about. Vintage electrostatic headphones almost always need to be looked at as foam breaks down and shorts out and glue dries and cracks so it can be a bit of a pitfall. Most are beyond repair.

You can buy a new Stax setup with a set of SR-202 headphones and an amp for 450$ from Japan and they are definitely much much better. Vintage Stax units are in high demand now so they cost more then the new updated units.
