Good bluetooth audio receivers provide solid connectivity, range, audio quality, and usability. They provide easy wireless streaming features to your existing home stereo or speakers, and can even give better audio quality for a great price.
Some bluetooth audio receivers will automatically reconnect to a 'paired' source when within range, while others need you to manually reconnect through your device’s Bluetooth settings.
