The Eargo Neo comes in a smooth and circular charging case that has a touch of AirPods feel rather than coming off as a medical device. The rechargeable battery of the Eargo Neo can be automatically charged once you put them in the charging case. The same charging case also contains Bluetooth, so when the earbuds are in there, a user can alter the settings through the mobile app.
This would mean that a consumer can’t adjust the settings while wearing the Eargo Neo because the Bluetooth tech is in the case and not in the buds. However, it’s a good thing for the battery life because the buds can have a longer playback time despite being so tiny.
