Plantronics makes EXCELLANT products, but this headset/microphone combo is NOT a match with LG cell phones. The ear volume is so low, the headset could never be useful. There is a three position attenuation switch built into the M110's 2.5mm plug....but it has no function when used (at least) with the LG VX8100 cell phone, and I have no reason to believe it would work any better with any other LG phones.
