3.5BELOW AVERAGE

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.

1.0BELOW AVERAGE

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.

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.
