It's a tragic piece of crap...really. I think they must have gotten some cheap shells made in China with no quality control and they're taking the amphenol jack (which looks like it could be a 6-pin but has the center filled) and screwing it into the shitty sleeve. It's not cracked so much as it was molded poorly by the look of it...super half ass.
And I'm not looking forward to soldering the wires from the Koss into that jack as I'm no artist. Trying to figure out now how to most intelligently do so.
Just seeing KG's post as I'm typing. I thought I'd read that several have used it and were opening up the female a bit? I'm all ears here (where's my PeeWee pic???)...
