IT HAS TWO microphones allowing for pure speech recognition featuring a revolutionary voice isolation technology. This allows the user to select between standard and max setting. The standard mode is used for normal everyday environments while the max is used in a much noisier environment when you need extra noise suppression - thus, allowing crystal clear conversation.
The unit functioned well in many different tests and environments and was very comfortable to wear. Easily adjustable, the controls are simple to use and setup was a snap. The Z9 is very small and lightweight at just 1.5 inches in length and weighing only .035 ounces.
