I know it is a little bit late(between 5:00pm 17 June 2014 (AEST) and 5:00pm 18 June, 2014.) but I just saw this promotion and post it here ASAP.
Currently the Wireless Speaker is 15% off and Headphones is 20% off, It is good value for me so I bought SRS-X9 and MDR-1RMK2. I think the MDR-1RMK2 is a good mate with my ZX1. Also the X9 is a real good SONY flagship Wireless Speaker, the X7 has good value too but compare with the AMAZON US ,the X9's price is more attractive.

I think people are better off getting Sonos play 5 which RRP $599, it's a much cheaper and better, in term of sound and iOS/Android/PC integration. As always Sony overprice everything in Australia.
