Thank you for viewing. Shop Japan Rakuchin Hearing M (Beige) Item No.: FN006159 It picks up sound with a sound collection microphone, amplifies the sound up to approximately 30 times with an amplification chip inside the main unit, and delivers the sound to the ear. In a TV volume experiment, some people reduced the volume from 43 to 17. You can hear the TV sound and conversations louder and more comfortably. It's rechargeable, so there's no need for troublesome battery changes. You can easily charge it by simply placing the main unit on the charging stand. #HearingLoss #Elderly #HearingAid #Assistance #HearingAmplifier #Hearing
