Product Overview

The AcoSound TW1-RIC-C is an 8-channel rechargeable Bluetooth-enabled RIC hearing aid developed for hearing aid distributors, medical device importers, clinic networks, wholesalers and private-label brands that need a connected receiver-in-canal product with a clearly defined starting configuration.

TW1-RIC-C combines 8 independent adjustable compression and amplification channels with 16 independent adjustable bands. The ACOD3101 Intelligent Multi-Core DSP provides 32 internal DSP channels, while ERAC 1.0 uses a Dual-Knee compression structure. The model also includes DFBC 2.0 feedback cancellation with two levels, SIW technology and ENDR 1.0 environmental noise reduction up to 17 dB.

Across the TW1/TW2/TW3 RIC-C family, the shared electroacoustic platform lists a maximum OSPL90 of 109 dB, HFA OSPL90 of 105 dB, maximum FOG50 gain of 45 dB and HFA FOG50 gain of 40 dB. THD is 3% at 500, 800 and 1600 Hz, battery current is 2.3 mA, and frequency response is 200–5000 Hz.

A Practical Starting Configuration for a Connected RIC Range

TW1-RIC-C is designed to give B2B buyers a straightforward first SKU in a three-model RIC family. The product focuses on core digital processing, rechargeable operation and app-based fitting without adding features that belong only to TW2-RIC-C or TW3-RIC-C.

For distributors, this matters because it creates an 8-channel model that can be positioned through verified specifications instead of vague entry-level language. The commercial story is based on 8 adjustable channels, 16 bands, DFBC 2.0 feedback management, ENDR 1.0 up to 17 dB and four selectable programs.

A buyer can therefore use TW1-RIC-C as the starting point of a product matrix and offer TW2-RIC-C or TW3-RIC-C when additional channel count, environment recognition, directional processing or multi-level wind management is required.

Core Processing and Feedback Management

TW1-RIC-C uses ERAC 1.0 Context Analysis Based Intelligent Multi-Compression Technology with a Dual-Knee structure. Eight independent adjustable compression and amplification channels provide the primary fitting architecture, while 16 independent adjustable bands provide additional frequency-adjustment points.

Feedback processing uses DFBC 2.0 with two levels. SIW Technology is included, while ENDR 1.0 provides environmental noise reduction up to 17 dB.

Transient Noise Management is provided in a Standard configuration. The model does not include the Environment Recognition Management System, Noise Source Tracking and Suppression, Wind Noise Management, Directional Dual-Microphone Technology or Directional Speech Enhancement found on higher configurations. These items are listed transparently in the technical specifications so distributors can compare the family accurately.

App-Based Fitting and Device Control

TW1-RIC-C supports app volume control and app program switching together with:

• Remote Fitting
• Auto Fitting
• Professional Fitting
• Smart Fitting

Bluetooth connectivity supports the connected product experience, while the fitting workflow remains described separately as app-based functionality.

The model also includes an Internal Sound Field Assessment System and an Internal Audiometer System. Adjustable turn-on delay, Occlusion Effect Management, low-battery notification and adjustable notification volume are supported.

Virtual-button program switching and virtual-button volume control provide additional software-based interaction. Memory After Power-Off is supported, and Personalized Data Storage is provided in the Standard configuration.

For clinic and distributor programs, these functions give TW1-RIC-C a broader service workflow than a hardware-only hearing aid. Product demonstrations can cover fitting, program selection, volume adjustment and follow-up functions without making unsupported claims about audio streaming or hands-free calling.

Rechargeable Hardware and Daily Product Handling

Rechargeable operation is supported across the platform. Nano Coating Technology is supported, with no specific IP or waterproof rating implied.

The RIC form factor places the receiver in the canal while the main device body sits behind the ear. For B2B buyers, this familiar architecture can simplify category positioning alongside other RIC products while rechargeable and app-based functions provide a connected product proposition.

Four selectable programs are available, and Memory After Power-Off helps retain operating data between use sessions.
