Brando has dubbed this the Ultimate Bluetooth headset, presumably because it comes with a built-in microSD memory card reader while supporting USB charging at the same time. The design itself isn’t anything revolutionary, and we would place this in the ultimate category only when it comes with solar panels to help it remain juiced up throughout the day as long as the sun is up and about. Well, there is nothing quite like carrying a microSD memory card with you wherever you go in your Bluetooth headset to boot, so it would be fun to give one of these $39 puppies a go. Alternatively, you can bring one back with an 8GB microSD card bundle for $65.
