RIC Design and User Controls
The GM-321 RIC form factor places the receiver close to the ear canal while keeping the main housing behind the ear. The supplied materials show a compact housing, a thin receiver wire, interchangeable ear domes, and user controls. Fit, comfort, performance, and suitability should be evaluated according to the individual user profile, fitting process, and applicable market requirements.
Environmental Listening Modes
The supplied product materials present four listening modes for smart, general, outdoor, and meeting scenarios. These mode names and functions should be confirmed against the final user interface, firmware, manual, and production configuration before they are used in customer-facing materials.
- Smart mode: Confirm the automatic or adaptive behavior supported by the final configuration.
- General mode: Confirm the intended default or everyday listening setting.
- Outdoor mode: Confirm the supported wind or environmental-noise processing behavior.
- Meeting mode: Confirm the voice-focus or group-conversation behavior.
OEM and ODM Customization
Goodmi supports qualified GM-321 OEM and ODM project discussions. Potential project areas may include logo placement, housing colors, charging-case ring colors, packaging, user guides, accessories, and approved product configurations. The final customization scope, MOQ, artwork requirements, testing, documentation, and lead time are confirmed during project evaluation.
Private-Label and Wholesale Supply
GM-321 can be evaluated as part of a private-label or wholesale hearing-aid program. Before quotation, share your target market, estimated order quantity, required documents, branding requirements, packaging needs, and launch schedule. This allows the manufacturer to separate standard product supply from custom engineering or documentation work.
Sample Evaluation and Bulk Order Process
- Share the target market, product requirements, estimated quantity, and branding plan.
- Confirm the standard GM-321 configuration and available customization scope.
- Review the sample, packaging, user guide, accessories, and product claims.
- Approve the final sample and written specification before bulk production.
- Confirm inspection, packaging, shipping, warranty, and after-sales procedures.
