I've had three pairs of Koss PortaPro headphones and really enjoy them. Interesting to read this but of history about the company. Thanks Mr. Koss!
My first ever "wireless headphones" were a a pair of standard PortaPros with a cheap bluetooth DAC taped to the top of them, got many strange looks, but it was a fun setup!
Maybe it was the sort of loss leader that's financed by the marketing department.
2. They charge $9.00 return shipping, and I bet make a healthy profit?
3. They might break even, minus the goodwill, on Ibud replacements? (I don't know Apple products anymore. Excuse the nomenclature. Ibud sounds off.)
