VT DUPLEX-CARDIOID Miniature Cardioid Headset

High sensitivity meets an open sound character.


The unique character of a real cardioid microphone in a nearly invisible headset: With its high sensitivity and precise polar pattern, the VT DUPLEX CARDIOD captures every nuance of the voice. For impressive performances on stage, in broadcast and live applications or presentations. For the production, Voice Technologies uses a sophisticated injection-moulding process, which not only allows the production of a long-living, rock-solid product, it also offers unique protection against water. This means the VT DUPLEX CARDIOID can be used even in challenging environments. In addition, a custom-made spacer prevents noise through contact.
