Is it better for teachers to use loudspeakers or wireless microphones?
According to the current trend, wireless microphones are more suitable for teachers to teach. The wireless microphone will not limit the scope of the teacher's class, and the teacher can walk around at will. In addition, the wireless microphone is getting better and better, which can be worn around the neck and is convenient to use. Wireless microphones are now divided into two categories: infrared wireless microphones and Bluetooth wireless microphones.
