D-502B Behind-the-Ear Digital Hearing Aid

This behind-the-ear digital hearing aid is specially designed for people with mild to moderate hearing loss. Equipped with a professional 16-channel digital processing chip, it separately adjusts high and low frequency sounds to accurately restore human voice, perfectly meeting daily needs such as face-to-face chats, watching TV and outdoor communication.

Adopting intelligent noise reduction algorithm, the device automatically blocks unwanted ambient noise so you can clearly hear others talking without harsh buzzing in crowded spaces. Weighing only 5.2g, its compact body fits snugly around the ear with an inconspicuous look. Paired with a transparent soft sound tube, it stays firmly in place during movement and causes no ear pressure even after all-day wearing.

It features a built-in 40mAh rechargeable lithium battery with 3.7V safe working voltage, offering up to 18 hours of continuous use after a full charge, eliminating the recurring cost of disposable batteries. With low total harmonic distortion and low equivalent input noise, it delivers smooth, distortion-free sound covering the full human speech frequency band of 450Hz to 3000Hz, effectively protecting your residual hearing. Simple physical buttons are easy for seniors to adjust volume and listening modes without complicated operations.
