First there are two types of Audio IQ.  AudioIQ makes wireless conversations effortless and pleasant, regardless of the environment. For incoming calls, AudioIQ automatically adapts to background noise levels and intelligently improves the receive quality, clarity and volume level. For outgoing calls, AudioIQ reduces background noise for listeners up to 7-8 decibels, or by approximately 50 percent. It also minimizes interference from artifacts such as speech distortions to maintain exceptionally clear voice intelligibility.  AudioIQ² makes use of two microphones–one that’s focused on your speech and the other that picks out distracting background sounds, such as road hum and construction noise–then compares data from the two microphones and eliminates the unwanted sounds, leaving your unique voice free to be heard clearly and naturally.

WindSmart provides wind-noise reduction technology for optimal sound clarity. It’s highly recommended for calls made outside (or in moving vehicles with open windows).
