This is a new, unused item. It will be shipped via Takkyubin Compact, so you can specify the date and time of delivery. 【One-Button Touch Operation】Munyday hearing aids are easy to use. Simply take them out of the charging case, and the indicator light on the main unit will turn orange. They will automatically power on within 5 seconds, and then you just place them in your ear. Operation is simple and can be used without any problems by the elderly and young people alike. 【4-Level Volume Adjustment】You can finely adjust the volume in 4 levels (1-4). With a high power of 125dB, it is designed for people with mild to moderate hearing loss. It pursues natural audibility. It constantly analyzes the surrounding sounds, reduces noise that interferes with voices, and reduces sudden loud environmental sounds, incorporating a noise suppression function to reduce the burden on the ears. You can select the optimal volume according to your situation and enjoy clear voices. Each time you touch the center of the hearing aid, the volume level will cycle through 1-4. 【Ergonomic Design, Comfortable Fit】The ergonomic design is fashionable and invisible, so it does not put psychological pressure on the user. The hearing aid body is a compact L-shape with a 175° arc, significantly reducing the burden on the ears and preventing pain even after long periods of wear. Before using for the first time, remove the insulation protection film from the hearing aid and charge it in the charging case for 2-3 hours. 【Type-C Rechargeable & Power Remaining Display】Munyday rechargeable hearing aids can operate for 20 hours on a full charge. The charging case has a built-in large-capacity battery, which can provide an additional 100 hours of use for the hearing aids. Charging starts when the hearing aids are placed in the charging case, and they can be fully charged in 2 hours. When the charging case is fully charged, it can charge the hearing aids about 5-6 times. In addition, the remaining battery level of the charging case is displayed numerically on the LED display, making it easy to see the remaining power. Thank you.
