| Bottom line | If you're looking for a relatively cheap way to add Bluetooth wireless audio streaming to a powered speaker or audio component with an audio input, the Logitech Wireless Speaker Adapter is a good solution. | For
cars with an auxiliary input but no native Bluetooth, the GoGroove SmartMini Aux is an effective means of adding both hands-free call capability and audio streaming from a smartphone. | Info unavailable | The Kinivo BTC450 is a good and inexpensive choice for adding Bluetooth to
cars with an auxiliary input, but it is short on features. |
