Sony WHCH510W wireless headphone for $79. At Sony is $129, but you can request for price match and combine it with $50 voucher (add few more stuff tp reach $100). Black colour is also available for same price.
Sony in-ear headphone MDREX155APW for $17. Sony sales it for more than $50 but they can't match it. Other colours also available at DJ.
I picked these up on sale for $59 at JB a few months ago, then they appeared at Aldi for $39. I went looking for another pair a week or so ago and they were about $130 everywhere, including Big W. What a wild ride!
