I'm looking to sell my Grado HF-2s. I was in on the original buy of these and they have been my only headphones ever since. Unfortunately I just do not get to use them basically ever, and there are other things I could use the money for, so I'm looking to sell these now. I have no concrete number of hours on them, though I'd definitely say there is less than 300 on them. Includes the pizza box, a pair of Grado flat pads, a fleece lined storage bag and a DIY 1/4" to mini adapter. (Switchcraft male plug, generic female, and generic cable, nothing special.) I'll be glad to answer any questions here, and I will consider any reasonable offers via PM.
