Maximum performance for open and enclosed cockpit, including VOX. Built using a high performance low power audio amplifier, using surface mount technology, with electronic speech processor to remove unwanted noise.

The UL-200 also has VOX. VOX is a system where the microphone is swithced off when you are not speaking. This in turn switches off tyhe speakers in the ear cups to give and exceptionally quiet headset. The VOX level is user adjusted by a small control on the headset.
