Having a little buyer's remorse with all the headphone and tablet purchases I've made in the past year. They are unopened with original receipt, which I will include for warranty purposes. Asking $ + shipping/paypal fees (or can use paypal gift). The box is light, so shipping cost (at least to the US) should be minimal. Part of me wants to try these out for myself before I sell them, but knowing me, once I try them I'll have an uncontrollable urge to keep them.

I'll probably open them before long if there is not sufficient interest.
