I'm not interested in any trades as I'm looking to downsize my collection of headphones. Audeze EL-8 (open back) - These are brand new in factory packaging. I just received these directly from Audeze as a replacement for my previous pair that I sent back for a wear issue. These were going to be my work headphones but I have returned back to my Sony MDR Z7 (recently fitted with a balanced cable) and I will be sticking with those. Given that these are brand new in the box, I am looking for $525 shipped. I'll eat the PP fees. I also have a Geek Out 720 and a custom balanced cable for an HD800 available for sale... haven't gotten around to posting ads for those yet, though. Sony MDR Z7 - These are practically new. I bought these in April before I did a bunch of traveling for work to use instead of my Shure SE535. The sound is a bit darker than I usually prefer, but there's something about these that I really like. They're not neutral, but they're fun to listen to. These come with all original accessories and packaging: headphones, single ended cable, balanced cable, 1/4" to 1/8" adapter, manual, case, and box. I'm looking for $600 plus shipping. I'll eat the PP fees. Sennheiser HD600 ($old) - I bought these last September and uses them at my desk at work. I decided to move the EL-8's to the office now (despite what it may do to my productivity) so I'm selling these too. I think most people are familiar with their sound, so no need to talk to that. These are in great condition with no signs of wear (maybe a piece of dust or two on the earcups) or paint chipping. Included are the headphones, stock cable with 1/4" to 1/8" adapter, custom (somewhat short) balanced cable, manual, case, and box. I'm asking $200 plus shipping. I'll eat the PP fees. Beyerdynamic T1 ($old) - These are in like new condition. I have only had them for a few weeks and they just aren't the sound I'm looking for. They're very comfortable headphones and very light. They have a good soundstage and great imaging. They're just a bit too sparkly for me. They're in great condition and come with the metallic case and original box. I'm looking for $650 shipped. I'll eat the PP fees.
