THEY WORK FOR ME.....
The Eargo is my first hearing aid. I have mild-moderate hearing loss. My main issue was difficulty hearing conversations in restaurants and other social settings (it was getting pretty bad).
Before breaking down and spending big dollars on a set of miniature hearing aids (vanity still looms large), I took a shot at Eargo. They have a 45 day return policy. FYI - I am still within the 45 days as I write this. So....here are my impressions after around a month of daily use:
First - the packaging and product design is great. They took their cue from Apple. The design is sleek and sexy. I feel as though I just purchased a high-quality electronic (not a clunky hearing aid). The psychological effect was that I wanted to wear them and make them work. They are cool enough that I tend to show them off rather than hide them away.
I will warn you that they take a bit of acclimatization. I was not able to simply put them in and - problem solved. It took some time to feel comfortable having something in my ear all of the time. Now, after a month of wearing them, I tend to forget they are in my ear. I have to remember to remove them before I go to sleep.
Functionally - they solved my problem. The sound is not high-fidelity. It boost the mid-upper frequency ranges, so things tend to sound a little tinny. But they work for me. I can easily hear conversations in restaurants and at parties now. I can listen to television at lower volumes and I have stopped asking people to repeat themselves in one-on-one conversations. So....for me....for the price....they are great.
As stated above, these are my first hearing aids. I have no idea whether more expensive products would be a better solve for my problem or whether they will fix yours. But the Eargo works for me. So far....after a month of use, I am a completely satisfied customer.
