Invisible Rechargeable Hearing Aid With 5 Settings

A true complete-canal hearing aid — the most discreet form factor available — inserted deep into the ear canal to align with its natural curvature and sit near the eardrum for physiologically accurate sound amplification. Constructed from medical-grade ABS plastic with soft, hypoallergenic earplugs for extended wear comfort. Technical specifications: frequency response 250–5500 Hz, max output 110 dB, max gain 30 dB, THD ≤15%, input noise ≤25 dB. Powered by a built-in Ni-based rechargeable battery (DC 1.5V, ≤4mA), charged via magnetic connection in the included compact case. Package includes: one pair (left/right), USB charging cable, magnetic charging case, and tuning stick. The intelligent noise reduction technology prioritises speech signals over background noise, delivering high-fidelity audio without artificial distortion. Five independent volume/gain settings let users adapt to varying listening demands — from quiet home environments to noisier outdoor or social settings. The universal design works equally well in either ear, removing the need to distinguish between left and right units. Its miniature size and seamless fit ensure long-term wearing comfort without ear fatigue or pressure — critical for elderly users who rely on daily, uninterrupted use.
