Selling these to consolidate the headphone collection. Both are like-new and I have owned them each for less than 2 months (I am the original owner). Both have less than 15 hours of listening time on them. I have the packaging and sleeve for the Sony's, but can't find the Senn's. No signs of wear. $45 shipped for the Senn's, $50 shipped for the Sony's. Buy both for $85. Senn's have the short (5ish feet) cord, Sony's have the coiled/long studio cord (7 feet maybe?)
