Both the M330 Silent Plus and the M220 Silent will deliver precision, durability and click feel but without any noise. According to Logitech, the new mice will still have the same traditional click feel but with over 90 percent noise reduction, while  Logitech Advanced Optical Tracking will provide precise control on almost every surface.

Both mice are also wireless and use a 2.4GHz wireless connection and are powered by a single standard AA battery, with an expected battery life of 24 months for the M330 Silent Plus and 18 months for the M220 Silent.

Both mice have three buttons, a standard scroll wheel and a 1000 dpi sensor, but the M330 Silent Plus has a slightly right hand fit design with contoured grips while the M220 Silent is an ambidextrous design mouse.

The M330 Silent Plus should be available directly from Logitech and in select retail/e-tail stores in September with a price set at US $30 while the M220 Silent comes in October with a price of US $25.
