 Radiant Firmware Update 1.4.1


General updates for improved connectivity and performance. To keep Sonic hearing aids in the best working order, they must always be upgraded to the latest firmware version

 EXPRESSfit Pro 2022.2.1


EXPRESSfit Pro 2022.2.1 is an update of version 2022.2, which corrects the performance speed when launching the fitting module. This version replaces the previous version.  

 EXPRESSfit Pro 2022.2.0


EXPRESSfit Pro 2022.2 supports the new Radiant custom hearing instrument styles, as well as the new Enchant SE family of hearing instruments (available in select markets only) and includes the following updates:

Additional measurement levels in Real Ear Fit
In 2022.2, an additional measurement level for real ear measurements (REM) in Real Ear Fit has been added. Soft levels (input levels of 50 and 55 dB) and loud levels (input levels of 75 and 80 dB) can now be chosen for REM modules when using the inter module communication protocol 2 (IMC2). Furthermore, 55 dB has been added as a soft level when using Verifit®LINK (loud and moderate input levels of 75 dB and 65 dB remain unchanged). Soft and loud levels are configurable in Preferences.

Transfer of targets from Real Ear Fit to IMC2 compatible REM systems
REM targets from the proprietary fitting rationales can now be transferred from EXPRESSfit Pro to IMC2 compatible REM systems. This makes it possible to verify against Best Fit Fast fitting rationales, optimizing the fitting and enhancing the overall experience for the patient.

Transfer of audiogram and fitting parameters from EXPRESSfit Proto Verifit
Patient audiograms and fitting parameters can now be transferred from EXPRESSfit Pro to the Verifit1 or Verifit2. This removes the need to manually enter the data directly into the Verifit, which reduces the risk of errors. 

Firmware update 1.4 for true hands-free calls
Radiant miniRITE and miniBTE hearing aids with firmware 1.3 offer hands-free communication with iPhone and iPad devices. Wireless firmware update version 1.4 enables push button functionality so users can accept, end, or reject calls with the simple press of the hearing aid push button.

New acoustic coupling option for miniBTE
EXPRESSfit Pro supports a new acoustic coupling option for the Radiant miniBTE. Joining the existing 0.9 mm thin tube, it is now possible to fit 1.3 mm thin tubes on the Radiant miniBTE T and miniBTE T R. This discreet option provides more output than the 0.9 mm tubing if needed.

 EXPRESSfit Pro 2022.1.0


Sonic EXPRESSfit Pro 2022.1.0 supports the new Radiant miniBTE T and miniBTE T R styles as well as all 5 technology levels 100|80|60|40|20 and new features:

Fitting Assistant

  • The Fitting Assistant has been extended to support feature settings of Radiant hearing aids, to facilitate fast and accurate fine-tuning.

Verifit®Link update

  • Enhancements to embedded Verifit®LINK functionality. The venting choice selected in the software is automatically displayed on the Verifit2 when using Verifit®Link.

Firmware update for existing Radiant hearing aids

  • Firmware update version 1.3 enables hands-free communication in existing Radiant hearing aids with select iPhones and iPads.

Note: Windows 7 and 8 operating systems are no longer supported. Please see system requirements below or contact customer service if needed.
