Build Quality
Eargo 7 hearing aids appear to be well build with an IPX7 rating, making them sufficiently durable against moisture which is important given their deep ear canal placement. The portable charging case is also a nice addition and should protect Eargo well when not in use.

Battery
Eargo are extremely small making their 16 hour rechargeable battery life impressive. The case offers additional on-the-go power and I found the magnetic charging bays a nice easy to use addition.

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.

Comfort
Comfort will vary by individuals depending on your tolerance to a deeper fitting hearing aid. Overall, I found them moderately comfortable through they can cause a tickling ear sensation due to their fit.

Design
Eargo's instant-fit, completely-in-the-canal, style is unique discrete. If you are interested in a nearly-invisible OTC hearing aid you will love their design.

Handling
Handling can be challenging with Eargo 7 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.

Pro Support
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.
