Air-conduction hearing aids with wearable cases are battery-powered devices designed to amplify sound for individuals with significant hearing loss. They use a microphone, amplifier, and speaker housed in a case worn externally (like a pocket or belt), transmitting sound via an earmold to the eardrum for improved auditory perception.
These devices are typically classified based on their amplification strength and intended use, often regulated as medical devices rather than consumer electronics. They may require compliance with hearing aid standards, though availability varies by region—some are sold directly to consumers, while others require professional fitting or prescription.
