A little explanation of AWD or Amazon Warehouse Deals since there seems to be some confusion for newer folks in the thread.
When amazon gets returns they check the merch and put it in the used category. Usually ships with prime shipping and comes in various states of good, like new, etc and varying prices depending on the condition. Like new and very good in the past for me has yielded pretty good results for me and it is mostly cosmetic box damage to some sort of degree.
Check around for other headphones in the used section to see if your favorite headphone, amp, dac, dap, etc has good prices. But exercise caution if a price is too good not to get a pretty pink headphone instead of what you wanted.
