< More Natural-looking >
Omnidirectional Consistency: It allows the mic to hang freely,
maintaining a steady pickup pattern
regardless of the speaker's head movements,
resulting in more natural-looking dialogue.
 Headworn Microphone

< Maximum Gain Before Feedback >
Consistent Audio Levels: Since the capsule stays at a fixed distanc
from the mouth, the volume remains perfectly stable
even if the speaker turns their head.
 Long Distance
Long Distance
< Extreme Mobility and Range >
High-end systems can maintain clear signals
at distances of 30 metres or more,
allowing presenters and performers to roam freely
through large venues or conference hall.
