Import Digital Hearing Aids — Buy in Bulk from Supplier in China

The Yoho Wheelchair Factory digital hearing aid operates on a 1.4V rated voltage with a current draw of 5mA, designed for extended battery life in compact form factors. It supports a frequency response range of 450Hz to 3500Hz, covering the core speech intelligibility band. The maximum saturation sound pressure level is 130dB ±4dB, indicating high output capability for moderate to severe hearing loss.

The device uses digital signal processing to enhance speech clarity while suppressing background noise, though the specific algorithm type is not disclosed. Equivalent input noise is rated at 32dB, which is typical for entry-level digital hearing aids. Components are assembled using standard surface-mount technology, with no indication of custom firmware or programmable settings. The product is intended for bulk distribution to distributors and clinics in developing markets.

These hearing aids are primarily sourced by medical distributors, NGOs, and low-cost healthcare programs seeking affordable assistive devices. They are not programmable via PC software and lack Bluetooth or remote control features. Buyers should confirm whether units include batteries, ear domes, or cleaning tools. Packaging is not specified, but standard bulk packing is assumed. Trade terms and minimum order quantities must be confirmed directly with the supplier.
