As a result, the user benefits from clear, interference-free sound during live performances, presentations or conferences.

The dynamic microphone capsules with cardioid polar pattern effectively reduce sounds coming from the sides and rear, focusing on the speaker’s or vocalist’s voice. This results in excellent speech intelligibility and natural vocal reproduction, even in loud environments.

Thanks to the two microphones included, it is perfectly suited for vocal duets, dual presenters or teamwork scenarios.
