Guys, instead of posting such a specialized item in the "For Sale" section, I though I'd give those who follow this thread first crack. I have a pair of AKG K400's that I'm thinking about selling. I'm the original owner and I purchased them sometime in the 90's (I think mid-90's). Cosmetically, they're in excellent condition. However, they do have a couple of issues. First, the right driver has the infamous rattle, mainly on lower-end bass notes (the left driver operates flawlessly). They're also missing the 1/4" screw-on headphone adapter, which was lost years ago. The elastics are stretched, but still maintain some firmness. They fit my head without issue, but those with smaller heads may need to replace them. These K400's would be ideal for those who are looking to mod, replace drivers, etc.
