Cardioid headworn micropho-
ne for applications where the-
re is an abundance of ambi-
ent sound.Much consideration
has been put into the physical
design of the VT800: the ad-
justable, gooseneck style mic
boom enables the talent to
stay close to monitor spea-
kers and to produce a clear,
intelligible voice over the noi-
se. The cable runs neatly to
the back of the neck for best
concealment. The headband
is highly resistant to corrosi-
on and is easy to clean.
