I picked up a pair of Radio Shack foldable headphones, 33-1173.
They look a bit like the eggos, and phones made by Panasonic, as well (sort of like the RP-HT850). They have a single-sided retractable cord.
First listen was not impressive. Grainy highs, generally unremarkable. I compared them to Senn MX500's and the diference was significant. They haven't been burned in yet, though. That'll happen this weekend, so I can decide whether I want to keep them or not.
Is anyone familiar with these? (They are listed on the RS website, but not in their aging print catalog.)
