This is Eargo's most affordable completely in-the-ear canal (CIC) device created to date.
The sound quality is top-notch and in line with other Eargo CIC products. The major differences are features. This one offers volume adjustments, and up to four sound profiles installed on the devices. It does feature the Eargo Sound Match, which takes a basic hearing test to determine your hearing needs. Once done, you can choose three additional profiles from the five available, to augment Normal mode on the devices.

I highly recommend these to someone looking at a first hearing aid of this type as an affordable step into better hearing.
