• RW12-RIC-M — 12 Channels
• RW16-RIC-M — 16 Channels
• RW24-RIC-M — 24 Channels

By providing multiple channel configurations within one consistent product family, the Charm Series enables hearing aid distributors, importers, hearing care providers and private-label brands to select suitable models according to their target market, product positioning and fitting requirements.

The Receiver-in-Canal (RIC) configuration combines a compact behind-the-ear housing with a receiver positioned closer to the ear canal, providing a discreet and professional hearing aid solution.

Across the series, the acoustic platform delivers a maximum output of 118 dB SPL, an average output of 114 dB SPL, up to 46 dB peak gain, and up to 42 dB maximum average gain.

The frequency response covers 200–5000 Hz, while equivalent input noise is rated at 25 dB. Total harmonic distortion is rated at 3% at 500 Hz, 800 Hz and 1600 Hz, supporting consistent acoustic performance.

With a working current of approximately 2.5 mA and battery life of up to 80 hours, the Charm Series is designed to provide extended operating time while maintaining reliable professional digital hearing performance.

The series is available in Grey and Beige and is designed for hearing loss ranging from mild to severe, subject to individual hearing requirements and professional fitting.
