Not that Bluetooth headphones are exciting or anything anymore, but the Jabra Stone - which the US guys reviewed back in October - is unique enough to be interesting. And it's now available in Australia through JB HiFi.
The headset will set you back $149, and looks much better than most headsets on the market. The US team really seemed to like it in their review, which should count for a lot if you're after a Bluetooth headset. If you're not, maybe just stick a regular rock in your ear.
