◎ First, please enlarge photo 4 and check the switches.. ○ Since the settings are tailored to your hearing, you may feel uncomfortable at first, such as hearing all kinds of sounds loudly. This is because it is difficult to completely filter out only the necessary voices and sounds with the noise suppression function alone. Normally, it takes about 3 months for the brain to get used to these sounds, so until then, please use it while adjusting the volume and sound balance. ♪ I checked for about 30 minutes, and it seems that it is easier to adjust the volume if you turn it down or turn it up from the lowest volume. ☆ It is a hearing aid and sound collector that will be appreciated as a gift for your grandmother or grandfather. You will hear the sound of the TV and radio better, and the conversation will be fun and your life will be more comfortable.

We have heard valuable stories from those who have purchased. As for the button battery life, it worked for 1 week with 5-6 hours of use every day. It seems to be kept for about 37 to 8 hours. Also, it is loose in terms of wearing and use! It is said that it falls off when it moves, so I have heard that it is necessary to devise a way to install it. Please devise a way to wrap the wire with tape so that it can be fixed.(Added 27 September 2023, 1:20 p.m.)☆ We also sell it on PayPay, so please check it out because we have added videos there.(Added at 20:02 on January 16, 2024)★？　Even though one person is currently being sold? There are people who do not make a payment for 3 days!. I think it's probably harassment, but I won't cancel it and will continue to post this lie. Do you have any other questions? , we look forward to hearing.
