Hey guys, I want to trade my New HE-500's for anything interesting. These were purchased on 6/24/2013 and received on 6/25/2013. Honestly, I took them out of the box to listen to and that's it. I haven't used them excessively over the past 9 days or did weird "burn-in" sessions. For people who previously saw this post I wanted to trade these HE-500's for a portable high-end headphone or earphone on my original classified but I already got an Ultrasone Edition 8 recently by trade on head-fi. Now I just want to trade these for anything interesting. Please PM if interested! If you want photos of the actual receipt, please PM me and I will send them to you. Note: If these are not traded by July 15 I am returning them to whence they came. Thank you all!
