Posted the deal on Amazon which is now Ozbargained. Found same on Catch.
Decent earphones with braided cable, mic and 3-buttons.
RRP is $49.99, but have usually seen them at half price. Current price makes it ~ 82% discount if you go by the RRP (which they don't justify imho).
Anyone looking for a backup earphones for calls etc. with Prime membership, this seems to be a decent enough bargain.
Lowest price ever as per camelx3
