Adjust the position of the microphone and
adjust the sound head to the position near the left and right sides of the
mouth to reduce the noise and obtain the desired volume and normal sound
The headphone used in the headset is:
omnidirectional and unidirectional （Cardioid）.
In general, the range of sound pickup using omnidirectional microphones is wider than other ranges. The sound quality of the pickup is clear and full, and it is mostly used in professional recording studios, studios, etc., which not only can restore the pure human voice perfectly, but also show excellent dynamic effects.
For this type of headset, you need to adjust the microphone to the left or right sides of the mouth, the distance from the corner of the mouth is about one finger, and perpendicular to the direction of the corner of the mouth, it can obviously avoid gas noise and achieve the clearest sound effect.
Cardioid microphone is more suitable for live performances, lectures and other public gathering places use, sound quality is remarkable, to restore the delicate clear vocals; at the same time closer to the mouth of the pickup unit design, narrower radio range, better control of ambient noise.
After the actual test, "Let the microphone and the corner of the mouth maintain about one finger's distance and keep the horizontal direction of about 45 degrees" is the most ideal hanging position, which can avoid the destruction of the air explosion sound, and can show the best sensitivity and sound quality.
