I am selling my Grado SR80 headphones. I am the original owner and love these headphones, but found that I do not listen to them enough anymore. They come in the original box and with a plug adapter and are in very good/excellent condition. I have tested them and they seem to be working perfectly. These are the original SR80 model (not the SR80i) and many prefer the original SR80 model.
The original ear pads were beginning to deteriorate, so there are no ear pads included with this set. One of the favorite replacement ear pad sets amongst Grado fans are these [ http://www.amazon.com/Replacement-Cushions-Sennheiser-SRI-Series-headphones/dp/B002B4OEZ0/ ] which are only $10 (or even less if you buy them directly from Sennheiser).
Pictures are attached, and here is a video of them in action taken today: http://www.youtube.com/watch?v=bSovdKEejQ0
Payment using paypal, no trades, shipping to Continental US only. Local pickup in San Francisco possible. Will insure package and ship with a surrounding box to protect the headphones (will use USPS or UPS, whichever is cheaper, but should probably be around $5 for shipping).
