Do not blow directly into the microphone during audition
Considering that the pickup part of the microphone is relatively precise, and the various factors are also very accurate, microphone professional tapping the microphone or air flowing to the microphone can easily cause damage or displacement of the parts, which will ultimately affect the sound quality.

Do not discard the battery once the microphone has not been used for many years
Today, standard wireless microphones or conference microphones require power. If the microphone has not been used for many years, the battery will need to be removed to prevent the leakage of the battery pack from corroding the microphone.

For condenser microphones, phantom voltages are not implemented blindly
Since your condenser mic's capacitor should be polarized to work properly, you should use phantom voltage when using condenser mics. Make sure you activate the phantom power change in the blender, observe the significance and polarity of the voltage, otherwise it will not only not work properly, but it may also cause damage.
