Tips and cautions:

1.The pickup head should be covered with a sponge cover, and the microphone is placed 1 to 2 centimeters in front of your mouth when you use microphone to amplify sound. It is suggested that the sponge cover should not be removed, because the sponge cover can weaken the air flow, reduce the noise, and make the voice be clear.

3.Microphone should not be close to the amplifier, and it's better if place the amplifier against the microphone. If howling occurs you can reduce the volume appropriately or enlarge the distance between the microphone and the amplifier. The microphone pickup head should not be grasped by hand, otherwise it will be easily howling because of resonance.
