A great Bluetooth headset
The HM7000 was released in the fall of 2011. The battery case makes it the Great White Buffalo of bluetooth headsets, so I feel safe in saying there hasn't never been anything like it. Again, by using a set of headphones with a microphone built in, you can avoid the issues of battery life and connectivity altogether, and look cooler in the bargain.
