Smart and convenient, no more complicated operations! This revolutionary user-friendly design is easy to use, even for the elderly. *To prevent feedback, please avoid covering the microphone with your hands or clothing. 【Easy Operation for the Elderly】With a light touch of your fingertip, you can adjust the volume in 4 steps. Confirmation sounds will play during operation, allowing you to confirm the setting by the number of beeps. The latest digital noise reduction technology suppresses ambient noise while clearly amplifying voices and TV audio (up to 35dB max) – protecting important "sounds" and reducing stress and anxiety caused by "difficulty hearing." Designed for those with mild to moderate hearing loss. ⭐︎Please Read Before Purchasing Regarding the characteristics of the hearing amplifier, "selective amplification" is not possible, so not only conversational voices but also environmental sounds (vehicle noise/wind noise/everyday sounds, etc.) will be amplified. Please use it in a quiet room. This characteristic is a common structural feature of all hearing amplifiers. Thank you for viewing.
