Anyone want to buy some Astro A40's + Mixamp?

So, since the new Xbox won't work with the old headphones anyway, I need to thin my collection a bit.  Already have Tb x41's and the A50's.  So, I have the original A40 system in black, with the Mixamp.  Original boxes, zipper case, all cables.

If interested PM me and we'll talk.  Thanks! :)

Obv much easier if you're in Chicago, but I will ship.
