< Discreet Audio Precision >
The iSound NL200 lavalier microphone is a small,
hands-free device designed for clear speech capture.
The compact microphone clip directly onto a speaker’s clothing,
making them nearly invisible on camera.
 Dropping Microphone

< 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
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.
