Need a new preamp, so I'm selling my ESP-950's. I picked them up earlier this year from another headfi-er, who bought them directly from Koss last year. They are in like-new condition, and include the headphones, E90 energizer, battery pack, and leather carrying bag. Like all ESP-950's, these have Koss's no questions asked lifetime warranty. I will only ship to those in the US, and payment can be made through Paypal + 3%. Thanks for looking!
