Multiple Choice

After years of development and testing,Jabra Corporation unveiled the Jabra 1000 ear-bud phone.The entire device fits in your ear.Jabra's transmitter picks up your voice by amplifying sound vibrations in your bones.Therefore,there's no microphone boom to jut out in front of your face.Because the bone vibrations must be amplified,a special chip in the part of the system that connects to the base of your phone uses noise-cancellation technology to screen out background sounds.This anti-noise chip generates a mirror image of outside noises,and the colliding sound waves erase each other.The main electronics package-about the size of a deck of cards-also monitors the quality of the phone line and automatically raises the volume of voice transmissions when the connection is weak.This tech-talk isn't cheap: the ear-bud phone lists for $329.
