Release notes:

 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.

EXPRESSfit Pro 2021.2


Sonic EXPRESSfit Pro 2021.2 supports the new Radiant 100|80|60 miniRITE T style and includes several helpful new fitting features:

Fitting Assistant

The Fitting Assistant is an interactive tool to fine-tune hearing aids during a fitting or follow-up visit. Based on a selected topic and patient complaint, EXPRESSfit Pro can identify and offer an appropriate solution. Solutions consist of changes to gain as well as other recommendations which can be applied to the hearing aids with the click of a button.

Remote Fitting update

Remote Fitting now supports In-situ Audiometry, which operates in the same manner as when it is performed in the clinic. To secure optimal quality of the in-situ audiogram, the ambient noise level in the patient’s environment can be measured through the hearing aid and displayed in EXPRESSfit Pro.

If multiple cameras and/or sound equipment are connected to the fitting PC, the HCP can select which of them shall be used for the session in the remote fitting window

Bone conduction handling for first fit prescription

Bone conduction thresholds can now be included or excluded with the first fit prescription for mixed hearing losses.

Improved awareness for Adaptation Level setting

The Adaptation Level setting is now shown in each fitting screen, to improve the awareness during the hearing aid fitting or follow up session.

Battery health indicator for rechargeable products

Lithium-ion batteries can lose their capacity over time and need to be replaced when they have reached the end of their lifetime. The new battery health indicator in EXPRESSfit Pro shows the remaining capacity of the hearing aid's rechargeable battery and recommends a battery change when needed.

ProbeGUIDE - Verifit®Link update

EXPRESSfit Pro now supports Audioscan's unique ‘Probe Tube Placement’ feature. This tool allows more precise and safer placement of the REM probe tube when using Real Ear Fit with Verifit®Link

REM module launcher

Connected REM modules can be launched directly from the REM settings screen in EXPRESSfit Pro

EXPRESSfit Pro 2020.2.1


EXPRESSfit Pro 2020.2.1 is an update of Version 2020.2, which includes fixes to some defects found after the release. Interoperability with some diagnostic equipment via IMC protocol is improved. The release will replace EXPRESSfit Pro 2020.2.

EXPRESSfit Pro 2020.2


EXPRESSfit Pro 2020.2 supports the new Radiant 100|80|60 product family with the following fitting features related to it:

24 fitting bands: To facilitate a better target match and allow more fine-tuning flexibility (100-level product)

A new Personalization tool: A set of 5 questions can be used to evaluate the end-user’s sound preferences, for better and more efficient personalization, and to improve the first fit acceptance.

Battery protection mode: Radiant hearing aids can be set into a sleep mode to reduce battery consumption in Stand-By.

Remote Fitting: Remote Fitting allows connecting the hearing aid to fitting software through the new SoundLink Connect app via the cloud Remote Fitting service, to make real-time hearing aid adjustments remotely. It supports direct communication between the end-user and HCP with video, audio and chat function.

All fitting features from EXPRESSfit Pro 2020.2 can be used in a Remote Fitting session, except In-Situ Audiometry, Feedback measurements, Real Ear Fit, and Tinnitus SoundSupport. Remote Fitting can be done with all hearing aid products from Sonic with 2.4 GHz wireless connectivity.

The Sonic SoundLink Connect app is available for iOS and Android, distributed via the App Store and Google Play.
