Was just browsing JB HI FI and saw this bonus offer, seems nice for decent "maybe" decent earphones.
So buy 1 get 1 free, just add to cart and add 1 more quantity so 2 and the price will stay the same as buying 1 but shipping price will go twice so better off picking it up.

ALSO available for Sony MDR-EX15LP In-Ear Headphones, but they seem to be not that great
