I have a pair of Beyer Dynamic DT 770-PRO Headphones.
They are pretty much brand new and have < 10hrs of listening time on them.

If you're reading this, you probably already know all about them, if not, there is plenty of information on the Internet.
Still have the box.

Let me know if you're interested - I can deliver or meet you at a Starbucks.

$150.00 cash monies.
