Wireless microphones and Bluetooth are both technologies that enable wireless communication, however, they are not the same thing.
Wireless microphones transmit audio signals to a receiver using a radio frequency (RF) transmission. This allows performers, presenters, and other users to move freely while speaking or performing, without being tethered to a device through a cable.
Bluetooth, on the other hand, is a short-range wireless technology that enables the exchange of data between devices such as smartphones, computers, and speakers. Bluetooth is often used for audio transmission, but it differs from wireless microphones in several ways. Bluetooth connections typically have a limited range (around 10 meters) and are designed primarily for consumer use, such as listening to music or making phone calls.
In summary, while both wireless microphones and Bluetooth use wireless technology to transmit audio, they serve different purposes and are not interchangeable.
