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.
Silk IX provide up to 20 hours of use per charge which is exceptional given their extremely small size. Recharging takes up to 4 hours, which is longer than some other models, but this isn't a significant drawback given their all-day battery life.
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.
While Silk IX hearing aids are not Bluetooth compatible, they still work with Signia's app using high-frequency coded signals. This is a valuable addition, although the communication is less stable than Bluetooth and the app offers fewer features compared to other Signia models.
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.
I found Silk IX very comfortable for an instant-fit nearly invisible hearing aid. Your hearing care provider should ensure they are fitted for optimal comfort and hearing benefit.
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 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.
I did not run into any issues while using Silk IX hearing aids. They are very easy to use once setup by your hearing care provider. Silk also have large color indicators making it easy to distinguish the left from the right hearing aids.
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.
You should receive quality hearing care and support from your provider. The Signia App should further enhance your experience with AI help and remote assistance should your provider offer telehealth services.
