Time to explore the peculiarities of these cheap Bluetooth receiver modules. They let you easily and cheaply add Bluetooth audio connectivity to sound systems with analog input: old stereos and radios, iPod docks, car hi-fi and more. They offer okay sound at a very low price. For DIY enthusiasts, these Bluetooth modules can be used for making cheap wireless speakers.

But shopping for these can be a gamble. Sometimes the range is great, sometimes - not so much. Noise could be an issue too if the wiring is less than optimal.
