As I need the money more than the headphones at the moment, I am selling my STAX-system. It consists of the SR-407 headphones and the STA SRM-3 energizer. I can sell them separately, but also together for a slightly lower price.
The headphoes have been well taken care of and are as good as new. They have been in a smoke and pet free environment.
The energizer is older and has had more owners, but it is in good working and cosmetic condition, with only a shallow scratch on the top.
