This handheld, personal amplifier is a great little portable device for amplifying quick conversations around you. Hold the speaker directly against your ear, much like using a telephone, and the microphone on the other end of the handle will pick up the nearby conversation and amplify it through the handset. Doesn't require using headphones or earbuds. Adjustable volume control ranges up to 45dB. Unit charges in a charging cradle which also sterilizes the unit as it charges.
