I asked if my order of K601 could be retermine to XLRs and this is the response from HeadRoom
Thanks for your email and pending HeadRoom order #98085.
Regrettably, the AKG k601 headphones have sold-out from our website (on clearance sale) and have been discontinued from Headphone.com effective immediately as stated on the product pages for that item.
Thus, your Headphone.com order has been cancelled. I am very sorry about the inconvenience.
I mean, the site clearly stated "In Stock" when I was ordering and now I'm getting nothing.
I was getting it for both my Bday and Xmas :(
