Do you want them new or used? I'm going to pick up a refurbished pair on amazon.com or buydig from around $130-$150. Usually i wouldn't bother with the refurbished, but the way i see it is- person buys the a900x's brand new, tries it on, doesn't like the wing system/ear cups sag on their head, doesn't know about the elastic trick, sends them back to the manufacturer, manufacturer has to re-sell them as refurbished.
...And i reap all the benefits!!.... muhahahahahahah... MUHAHAHAHAHAHA.... >.> lol
New if the price is around 150-160. I remember seeing these brand new at those prices. I guess I missed it.
If it's refurbished that would be my ideal scenario too. But you never know with the one that you get.
