This is advertised in the latest Big W catalogue. Limited colours are available online, your best bet would be instore. The catalogue says on sale from Thurs 19 Sept, but the reduced price is already showing up online.
Description:
The MDR-XB200 packs a mean bass punch with 30mm driver units and Advanced Direct Vibe Structure technology. Premium leather ear pads and soft head cushions provide superior listening comfort, while sealing in sounds for an exceptionally rich bass experience.
The XB00 includes an advanced housing seal to maximise air movement and reproduce higher factor base. It is ideal for mainstrem music styles (including urban, house and pop).
Cant seem to buy them online. Looks like instore is the only way
