SPECIFICATIONS

The JINGHAO Rechargeable Invisible Digital In-Ear Hearing Amplifier is a compact personal sound amplification device (PSAP) designed to make everyday conversations and environmental sounds easier to hear. Its discreet in-ear design, digital sound processing, rechargeable battery, and multiple ear tip options provide a comfortable listening experience for adults and seniors seeking an affordable sound enhancement solution.

Important: Although often marketed as a "hearing aid," many JINGHAO models sold online are personal sound amplification products (PSAPs) rather than FDA-regulated prescription or over-the-counter (OTC) hearing aids. They amplify surrounding sounds but are not intended to diagnose, treat, cure, or prevent hearing loss. Individuals experiencing hearing loss should consult a licensed hearing care professional for evaluation.
