Stable and comfortable. Daily care is simple and orderly.
After adjusting the M-size earpiece to fit my father's ear canal, these rechargeable hearing aids sit securely and comfortably. The earpiece case organizes them by size, and the cleaning brush effectively removes hard-to-reach earwax—these thoughtful details make daily maintenance simple and organized.

Great hearing aids!! Highly recommend!
I ordered these for my elderly father and could not be more happy! He can finally hear like he used to when he was younger :) He tells me they are very comfortable, the battery life is amazing, and he now can’t live without them. Customer service at this company has been amazing as well, we highly recommend this product and company.

Great!
I got these for my mom who’s hard of hearing and almost completely deaf in one ear. She had her past ones from a hearing aid place and they broke and they are trying to charge her $5,000+. She put these in and immediately loved them. She had to adjust a bit, because you can actually make them quite loud. I’m very happy to have found her an affordable hearing aid that works just the same. Also customer service is great and very fast!

Charging
The hearing aide worked fine. But the charger stopped fully charging the hearing aides. So they die after an hour. We have only had the product for less than two months. I tried troubleshooting and nothing worked

The one-click startup design is very considerate.
Operation is incredibly simple! The one-button power-on design activates with a 3-second press, and the volume control buttons are clearly labeled. Even my 80-year-old grandmother can use it effortlessly—truly a senior-friendly design. This rechargeable hearing aids is incredibly thoughtful.

Not for musicians.
If you are musician and need hearing aids, I'm afraid you will need to spend more money and make sure it has an app and Bluetooth capability so you can adjust volume and other things so your instrument won't sound tinny. The small buds that go over the speaker part were still too big for my ear, but my left over Phonak buds fit the speaker and that has made a difference. There is a buzz that happens at a certain pitch and I'm at the minimum lower volume so I can't lower things anymore. These are louder in reception and could use more volume decrease. However, it's good to hear what people are saying to me. Words are not muddied. So, if you're not a musician, these are fine.

The just-right protrusions are superb.
Single-handed operation is so convenient! My right hand is not very dexterous, but I can easily press the buttons with my left thumb to adjust the volume. The button design has just the right raised parts, so it won't be accidentally pressed or stuck. All functions are integrated on this ingenious button, simple yet not crude. This rechargeable hearing aids is superb.
