Kikoeru Hon (Hearing Aid) Used item Includes main unit and case only. My parents used it for a while and then stored it away. Since there is no charging adapter, if you already have one, how about purchasing this as a second unit? (I tried various adapters I have at home, but the hole is small, so it seems you can't charge it without the dedicated adapter.) When I turned on the switch, the lamp lit up as shown in photo 6. Please purchase this item only if you agree to the above conditions. #cococimo #cocochimo #kikoeruhon #earphones #headphones
