Eargo 8 hearing aids appear to be well build with an IP68 rating, offering great protection against moisture and debris. The portable charging case is also a nice addition and should protect Eargo well when not in use.

App Features

I found Eargo's app to be packed full of useful features like the Sound Match hearing assessment and automatic noise reduction controls. You have plenty of options for personalization though adjustments are not always reliable as Eargo relies on phone speaker commands instead of Bluetooth.

Handling

3.0BELOW AVERAGE

Handling can be challenging with Eargo 8 due to the small size and reliance on tap controls. Furthermore, Eargo relies on acoustic indicators for wireless communication, which is less reliable than Bluetooth and caused me several problems.

Eargo is one of the first direct to consumer hearing aids, but support is unfortunately limited to to their Client Care team and personal hearing professionals. While Eargo claims they work alongside audiologists, it is not the same as direct professional hearing care.

Insio Charge&Go AX
Adjustment BandsAdjustment BandsThese are frequency-divided sections that can be adjusted in a hearing aid in order to amplify sounds. Although there are rarely more than 10 frequencies measured in a hearing assessment, having more bands that can be adjusted may allow for improved speech understanding and user comfort.
No

Adjustment SynchronizationAdjustment SynchronizationThis feature allows for a more pleasant listening experience by ensuring that both hearing aids process sound the same way. If one hearing aid changes its processing in response to noise or speech, it will send a wireless signal to the other hearing aid so both process sound in the same way.

Automatic Phone ProgramAutomatic Phone ProgramHearing aids with this feature can detect when a phone is placed near them and automatically switch to a phone program. In this setting, the hearing aids will reduce background noise and increase the volume of the phone.
No
TwinPhoneTwinPhoneTwinPhone is the optimal solution for these wearers. It is automatically activated by a magnetic signal, so the wearer hears the caller in both ears for better understanding.
DirectionalityDirectionalityDepending on the types and number of microphones a hearing aid has, the hearing aid may be able to boost sounds from specific directions (by reducing sounds from other directions). This can be helpful to focus on a speaker directly in front of the hearing aid user, as well as to give the user information about where different sounds are coming from.

Feedback SuppressionFeedback SuppressionIf any sound amplified by the hearing aid escapes the ear canal, it may reach the hearing aid’s own microphone and cause a harsh whistling noise. Some hearing aids are able to recognize when this feedback occurs and reduce or eliminate it.
No
Feedback cancellationFeedback cancellationHigh-speed monitoring and control of feedback risk in individual processing channels.
