Shuonki Hearing Amplifier for Seniors (2025 Upgrade Edition) USB Rechargeable, Neck-Worn, 6 Volume Levels, Lightweight, Noise Reduction, Anti-Feedback

[2025 Upgraded Neck Hearing Amplifier] Utilizing cutting-edge industry technology, these headphones are both a hearing aid and Bluetooth headphones. The 16-channel digital chip and intelligent noise reduction function ensure clear audio. Equipped with feedback suppression, they offer a comfortable fit. The sound collection function automatically activates when powered on, eliminating feedback and eliminating the need for complex adjustments, enhancing wearer confidence. [No annoying feedback] The built-in feedback suppressor and predictive feedback suppression technology, along with an adaptive feedback detection and attenuation algorithm, predict sudden sound peaks in advance and quickly capture and suppress them, providing a more comfortable and clearer hearing experience. To avoid feedback: 1) Select appropriate silicone earpieces and ensure they fit securely, eliminating any gaps between the earpieces and your ear canal. 2) Do not cover the microphone with your hands during use, as this may cause feedback. [Innovative Three Operation Modes] 1. Independent Sound Collection Mode: No Bluetooth connection is required to use the sound collection function; 2. Independent Bluetooth Mode: Manually turn off the sound collection function and use the Bluetooth function; 3. Sound Collection and Bluetooth Mode: Connect to your mobile phone's Bluetooth and use both the sound collection and Bluetooth functions. When a call comes in, the sound collection mode automatically turns off. When the call ends, the sound collection mode automatically turns on. The latest core algorithms are used to deliver a more layered sound and improve the clarity of human voices, ensuring effective sound collection and conversations. [Comfortable Fit & Independent Left and Right Volume Adjustment] Designed based on the principle of universality of the auricle, the ultra-soft silicone earpieces prevent ear pain even when worn for long periods of time. Double-click the power button to activate equalization mode and adjust the left and right sound collection volume independently. Please note that it may take some time for the sound collection device to fully function. Don't give up immediately because it doesn't work. It takes some getting used to.
