Saw this deal but not sure if it's the cheapest thing out there. After looking at all the old posts on OzBargain it looks like one of the cheapest sales at the $130 mark. Not sure if Amazon has any sign up/cashback/coupons, but feel free to check before you purchase if you are really considering it. I tried to check out from Amazon and it said free shipping.
Looks like there's a cashback reward.
You can get all four colours (green, red, black, and white) from Amazon. At JB Hifi they're selling it at $199 in black and white.
I got a price match at JB-HiFi and paid 140 for them. I also got the two year warranty on top of the one year, for $22. The rep was really nice and explained the warranty to me. They also told me to keep a digital copy of the receipt :) This was at the store upstairs in the Westfield on Pitt Street.

I got these on the last deal, save your money. The ear plug/rubbers don't fit anyone - I couldn't even give them away. Junk
