Gear: Azio USB Micro BT 4 Adapter with Apt-X, other Apt-X devices.

Below, we can view the contents that come in the Azio BTD-V400.  This is a USB Bluetooth 4.0 wireless transmitter that works with computers.  The adapter has CSR Apt-X technology, which allows for better audio quality over wireless.  The audio quality will be important, as there are a few upcoming videos which will feature a few wireless speakers.  UPDATE: the details on the software has been posted, you can also download the latest drivers at that page.
