A Bluetooth transmitter is a small device that helps you connect wireless headphones or speakers to devices that do not have built-in Bluetooth. Many TVs, PCs, gaming consoles, and old audio systems only support wired audio. A Bluetooth transmitter converts that wired sound into a wireless signal so you can enjoy audio without cables.
