Acoustic Voice Activity Detector (AVAD) provides a fail-safe mechanism when the Voice Activity Sensor (VAS) doesn't touch your face. When the VAS is not touching the face, Jawbone PRIME performs as good as or better than any other noise cancelling headset. When the VAS touches the face, you get the turbo-boost to the NoiseAssassin performance.

Jawbone PRIME also has a subtle wind feedback mechanism built into the headset that gently alerts you when voice clarity is compromised due to wind gusts so the user can self-correct. While Jawbone PRIME does not completely remove the impact of wind, it does more than any other headset to remove wind and alert the user to the fact that wind may be affecting the conversation. This is the beginning of Jawbone's journey toward silencing wind.

Functionally, the design has also been enhanced by a slight indication in the shield's texture, a small tactile crease that indicates where the switch is located. The inside contours of the product follow your face in a perfectly comfortable manner, while new ergonomic earbuds have been refined to keep the Jawbone in place without an earloop for most wearers.
