I think slaughter is referring to the fact that the hd555 and hd595 literally share the same drivers. The 555 just has an adhesive strip of foam covering the drivers to make them sound worse. Anyone with minimal DIY skills can open them up and remove the foam.
Still, I can understand if someone payed $15 for the title upgrade. I wouldn't pay it because I'd just feel cheated by sennheiser.
