Been trying to get my hands on a set of these for a while.
The 4AAA Plus is Koss's 1980s reproduction of the 4AAA, designed with a lower-impedance voice coil and a lighter diaphragm so it was easily driven out of portable CD players from that time. It has the same design as the original 4AAA but with a full black and silver casing. Looks pretty damn sweet.
The price is not set in stone by any means and I'm open to suggestions. Shoot a PM my way if you're willing to negotiate.
