Oh gosh, these headphones bring a tear to my eye. Since there are not pictures attached to this posting, I do have to say, these were some of the original run of the HE-5LE by HifiMan. They have the brown woodgrain box, with a few scrapes. However, the cups of the HE-5LE are not the gloss black like you normally see. They are actually a matte black finish since HifiMan used a very thin rubber coating on the cups on the original HE-5LE headphones.
These are really gems. Additionally, I do have pictures via the following link in my gallery where you can see the matte finish cups, as well as the real leather custom headband that was sewn in place over the existing HifiMan leather band.
Additionally, here is a link to some pictures from HifiMan depicting the HE-5LE in the special finish, as well as the brown woodgrain box they utilized at the time. http://www.head-fi.org/g/a/747914/he-5le-headphones-by-hifiman/
Best of luck with the sale!
