250 ohm version. I've had these since November 2002. They haven't been used at all since last October, and they weren't used much after the first few months I've had them. I want to sell them and buy a portable setup.\n \n Here's a pic:\n \n http:\/\/mywebpage.netscape.com\/tehpressman\/phones.jpg\n \n I'd like to get $140 shipped for them. I prefer paypal.\n \n email me (firstname.lastname@example.org) or pm me with any questions. Thanks.
