A Bluetooth Audio Receiver can be a useful addition to any car stereo or home cinema system. The device can also be used to connect to headphones. You should choose a model that's small enough to fit in your car's glovebox and can be plugged in without requiring an electrical outlet. There are models designed especially for cars and work with standard AC wall adapters, while others can be charged by batteries. In a car, the Bluetooth Audio Receivers typically have a single 3.5mm AUX input. Cinema systems may require RCA and/or optical inputs.
The quality of a Bluetooth Audio Receiver can vary considerably. A high-quality receiver should sound as good as a direct wired connection, but the quality depends on its audio circuitry and built-in DAC. Unfortunately, Bluetooth doesn't have the bandwidth to send CD-quality audio over short distances. Instead, it uses a codec to compress the signal so it can be transferred to other devices. This codec varies the bit rate and compression, based on the wireless bandwidth available.
The Bluetooth Audio Receiver is easy to use. It only requires one device, and no extra phone equipment is required. The technology is very secure - you won't accidentally broadcast your private voice notes. Because it's small, it fits in any car or room. Furthermore, you can even manually authorize it if you prefer. It can even be paired with more than one Bluetooth device. If you don't own a Bluetooth device, you can purchase one in a wireless store.
