The Voice Technologies VT800 is a lightweight Cardioid headworn microphone for applications where there is an abundance of ambient sound.
Description
Much consideration has been put into the physical design of the VT800: the adjustable, gooseneck style mic boom enables the talent to stay close to monitor speakers and to produce a clear, intelligible voice over the noise.
The cable runs neatly to the back of the neck for best concealment. The headband is highly resistant to corrosion and is easy to clean.
