Sontro Hearing Aid Review

Sontro Hearing Aids have been designed to be sold over-the-counter, once the FDA’s regulations are finalized. The cost is $999.00. They connect via Bluetooth to the otoTune app, which administers a “clinically-validated” hearing test to identify the user’s hearing thresholds. The Sontro hearing aids are automatically programmed to the user’s hearing thresholds. Once the three-minute test is complete, users can adjust volume, listening modes, and use a sound equalizer directly on the otoTune app. They also have access to toggle switch options such as feedback cancellation and noise reduction.

When we initially received our Sontro devices, they turned on, but we were unable to connect to the otoTune app. Customer service was not able to effectively troubleshoot or resolve the connectivity issues via phone. They eventually agreed to replace the devices. The second set of devices paired immediately. The Bluetooth pairing process was simple; with the battery doors closed and the devices in proximity of the phone, all we had to do was click the “Connect” button on the app. Despite the Bluetooth connection, the devices are not able to stream phone calls or media at this time.

The 3-minute hearing test was accurate. There is a simple sound level meter that instructs the user to ensure the ambient noise is below a certain level prior to beginning the test. The user is then presented with two boxes on the screen: one on the left labeled “L” in blue, and one on the right labeled “R” in red. Tones are presented to the user and you click the corresponding L or R button. While the testing is somewhat intuitive for me as an audiologist, there are no testing instructions and the beeping begins quite loudly.

After the testing has been completed, the user is given the option to “program” the devices based on their thresholds. The “Control” page of the app is where users can adjust the volume using “dual control” (binaural VC adjustment) or “left only,” and “right only.” The description of the devices makes it sound like they will adapt to your listening environment and switch modes automatically, but this is not the case. The user must switch into a different listening mode via the app.

Sontro Hearing Aids are great “starter” devices. They are simple in design and concept, and the phone app is intuitive.

Unique Perks and Features

Bluetooth connectivity (iPhone/Android compatibility)

  • Initial BT pairing to the app was fast and intuitive. Reconnecting to the app after it had been closed was glitchy.
  • The otoTune app uses Bluetooth to pair with your phone and to complete the hearing test process within the app. The otoTune app will pair with both Android and Apple smartphones. Android versions 6.0 and iOS versions 11 and higher will pair with Sontro Hearing Aids.

Dedicated app/third party app

The otoTune™ app permits people to test their hearing at home for self-fitting Sontro Hearing Aids. Following a 3-minute otoTune hearing test, the patient can make adjustments to assure the Sontro Hearing Aids are correctly fit and provide the best amplification essential to enhance communication.

Personalization/customization/adjustments

You must have the devices paired with the otoTune app to customize other settings such as the volume, listening mode, and equalizer.

Remote phone app/audiologist consultation

Not offered

Tinnitus Relief – white noise generator/sound masking

No

Cost – $999.00 which includes 2 Sontro hearing aids,

Sontro Hearing Aids are great “starter” devices. They provide an opportunity to retain “Tested Not Treated” patients who are primarily concerned with cost vs. benefit. They are simple in design and concept, and the phone app is intuitive.
