If you’re looking for Bluetooth connectivity for entertainment and tablet app interface, you don’t have to spend big on a major audio system upgrade. Consider that a full-up GMA350c audio panel interface could easily top $5000 for an average installation. That’s a hefty price to pay for Bluetooth connectivity. As an alternative, you might try connecting your devices through a Bluetooth headset, including the updated Bose A20. While the enhanced A20 isn’t a new model (it was introduced five years ago), the set now gets the Bluetooth capability the market expects—including wireless music streaming. The only way to listen to music with the previous version was to plug it in via stereo patch cable. Unchanged is the A20’s 12-ounce top end, including its fit, finish, ANR audio performance and comfort. New to the A20 is a redesigned control module, which requires swapping the interface cord (also called the downcable.) The downcable also has a new microphone in favor of an improved and more adjustable one, which can be attached to either earcup.
