Previous deal was $19.90 http://www.ozbargain.com.au/node/54016
I dont know about the quality of this item but I got philips HP2000 for $15 (harvey Norman last week christmas sale) which is almost similar and the sound quality is good.
I'm sure this one should be better than mine.
I used this headphone before. The sound quality is good but it leaks sound despite being closed. Its a huge headphone, will make you head small :)
