Bluetooth connectivity is maturing and can be found in all sorts of tech products. You’ll be hard-pressed to find a smartphone or tablet without Bluetooth as a standard. Some people even turn their old smartphones into portable media players using Bluetooth.
Bluetooth adapters (also called receivers) are therefore widely available and affordable.
Bluetooth adapters come in many shapes, sizes, and functions. Most connect to stereo systems, amplifiers, or receivers via a 3.5mm, RCA, or digital optical cable, which may or may not be sold separately. These devices also require power, usually via an included USB or wall plug, and some have built-in batteries that can last for hours. Once you’ve connected them, you simply pair the adapter with a smartphone or tablet and enjoy audio control right from your pocket.
