Xmart Volume turns the volume on your headphones down automatically when someone talks to you near your computer. It does this by utilizing the built-in microphone of your Mac or iSight. Features include:

• Smart Active Volume Control
• Environment sound level monitoring
• Background noise level adaptation
• White tone HUD interface
• Semi-opaque window

Although not guaranteed, Xmart Volume reduces your chance of missing important announcement when you are enjoying a movie or iTune on your MacBooks while waiting for a flight in airport.
