Asahi Denki ELPA Earphone Microphone Type Hearing Amplifier EARLIS Model Number: AS-P001 NV Dark Navy This is a compact hearing amplifier for those who have difficulty hearing. The main unit can be put in your pocket for use. Used for testing 3-4 times and then stored. It was for my grandmother who had difficulty hearing, but it seems she didn't need it. I hope someone can make use of it. * The ON/OFF switch is a little stiff. Includes two ear tips attached to the cable and three spare ear tips.
