About This Product
The RTT MEDI SH03 RIC hearing aids combine advanced digital sound processing with a discreet receiver-in-canal design for comfortable everyday listening support. Built with 16-channel WDRC, 64-band EQ, feedback cancellation, and noise reduction, the SH03 is designed to help users hear speech and surrounding sounds more clearly across different environments.
The compact behind-the-ear body keeps the main device low-profile, while the receiver delivers sound through a soft ear dome positioned in the ear canal. Three selectable noise-reduction modes allow users to adapt the listening experience based on their surroundings without complicated controls.
A rechargeable design and digital charging case make the SH03 convenient for daily use, travel, and extended periods away from a power outlet.
Key Features of the RIC Hearing Aids
16-Channel WDRC Processing
The RIC hearing aids use 16-channel Wide Dynamic Range Compression (WDRC) to process different sound frequencies independently. This helps provide better balance between softer and louder sounds instead of applying the same amplification across the entire frequency range.
64-Band EQ
A 64-band equalization system provides detailed frequency adjustment for more refined digital sound processing and a more natural listening experience.
3 Noise Reduction Modes
Choose between:
- Quiet Mode — for calmer indoor environments
- Moderate Noise Reduction — for everyday social settings
- Deep Noise Reduction — for environments with more background sound
This gives users a simple way to adjust the listening experience based on where they are.
Feedback Cancellation
Integrated feedback-control technology helps reduce unwanted whistling and feedback during normal use when the hearing aids are properly fitted.
Up to 15 Hours per Charge
Each hearing aid provides approximately 15 hours of operation per charge, depending on volume, listening environment, and actual usage.
The charging case provides 120+ hours of total available use and can recharge the hearing aids approximately 6 times before the case itself needs to be recharged.
Digital Battery Display
The charging case includes a clear digital battery display so users can quickly check the remaining charging-case power.
How to Use
- Choose an ear dome that fits comfortably and securely.
- Place the main hearing-aid body behind the ear.
- Gently position the receiver and ear dome inside the ear canal.
- Turn on the hearing aid and begin at a lower volume.
- Use the volume controls to gradually adjust the sound to a comfortable level.
- Select Quiet, Moderate, or Deep Noise Reduction Mode based on the surrounding environment.
- After use, place both hearing aids into the charging case for storage and recharging.
Keep the ear domes and sound outlets clean and dry to help maintain consistent performance.
Who Is It For?
The SH03 RIC hearing aids are designed for adults looking for a rechargeable, discreet hearing solution for everyday situations such as conversations, television, family gatherings, outdoor activities, and social environments.
The low-profile design may be especially appealing to users who prefer a smaller behind-the-ear device with an in-canal receiver rather than a larger traditional hearing aid.
Anyone experiencing sudden hearing loss, ear pain, drainage, severe hearing impairment, or significant changes in hearing should seek professional evaluation before relying on a hearing device.
For general guidance on choosing and using hearing aids, visit the U.S. Food and Drug Administration (FDA).
