They're mine. I've got a lot of headphones in house right now. With a major home renovation, I've had my main rig mostly put away (though I do put it together for weekend use) so I've been listening to portable headphones mostly over the summer:
Now with the renovations nearing their end (next week...fingers crossed), I'm looking at clearing out some headphones and with the SR-009s, LCD-3s, HD800s and TH-900s (plus some of the portable headphones...though some are gone and some will be gone), the PS500s didn't get the listening time they deserved. So I guess its time that they found a new home.
