When purchasing a mobile karaoke microphone, the sound quality must be the primary consideration, and it is particularly important to understand the parameters of the microphone.
Sensitivity
Microphone sensitivity is usually identified in mV/Pa, negative -dB. speaker microphone bluetooth，The lower the negative number, the higher the sensitivity. Therefore, for a good quality microphone, the smaller the negative value, the higher the sensitivity.
Frequency response
The ideal frequency response range is 20Hz-20KHz, which matches the hearing frequency band of the human ear. Generally speaking, the lower the fluctuation value, the better the sound quality of the microphone.
signal to noise ratio
The greater the signal-to-noise ratio, the less noise mixed into the signal, and the higher the sound output quality. For mobile karaoke microphones with better quality, the signal-to-noise ratio is generally not lower than 70dB.
