I've been using these for over a year and overall pleased with them due to the price and size. They work great after proper volume adjustment and using the correct ear plugs. I would recommend starting out with a low volume and increase a little at a time. If volume is turned too high, frequent squealing will occur. My only issue is the quality as the last purchased ones have a very short battery life and volume goes in and out. I waited too late (past 30 days) before returning.

Got these (L and R) for my wife, who has mild hearing loss in the range that makes it increasingly difficult for her to hear normal-volume speech in conversation, and the soundtracks of movies clearly. These were an interim attempt to avoid the high costs of actual hearing "aids"... and it seems to be a very workable solution for her! The factory set the amplifier volumes to midrange, and we had to turn it to the lowest setting, which is just right for her individual hearing loss. She also has tiny ear canals, and the supplied ear pieces assortment had a set that fit her comfortably. I am able to speak to her in a lower-than-normal volume now, and she catches every word! We also watched a movie, and she said she was able to hear and understand the talking during the entire movie... no more loud TV volume! In summary, these were a great sution for us, and they work extremely well. Just follow the simple directions for use (especially for first-use), and if you encounter any problems!

I have bought very expensive hearing aides in the past, and paid thousands. I currently have hearing aides from Cost-co, they are very good and worth the money. I bought the Hearing Amplifier to use when working in the yard, doing things that might make be perspire. The over the ear aides from Costco get damp from sweating, causing possible damage. These Amplifiers are in the ear, and I have no worries. I put them in my ears one morning, worked in the garage, , my wife and I went out for the evening, and I didn't notice I was wearing the amplifiers until we got home and I was getting ready to shower. These are awesome and I hear very good with them.

This works -- I will give the details below. But it is not branded "miracle ear", which is a long established company. The information above is obviously written in poor English by a Chinese speaker. They imply the brand name, but this is just a generic device from China. It is cheap and cheaply made. It works well. It may not last. For now, I am okay with it. I sure was not going to pay $3000 for anything fancy. If this fails, I may pay the small price for another.

Most people with moderate hearing loss in older age have lost the higher-frequency range of hearing -- from 2000 hz to 4000 hz. This is the range of hearing that adds brightness to sound. It is the sound of wind in the trees, the higher frequency richness of music. Without that range of hearing, sounds seem muffled. Eventually speech can become harder to discern. As a doctor, I have done hearing checks, and I know I lost about 40db of hearing in my left ear in the the 2000 to 4000 hz range. (It was hit by an explosion decades ago, and damaged.) My other ear is not so bad.

This device clearly amplifies that critical range of hearing from 2000 to 4000hz, perhaps by design. Setting the volume to about 1/3, what I hear is not louder or in any way annoying. But that critical range of hearing is given back by the amplification. That is all I wanted in a hearing aid. Listening to music with that range given back is really nice. I don't endorse the way this device is listed, but for the small cost it is worth a try. The batteries last up to a week. A pack of 60 from amazon costs about 15 bucks.

Ok for the money but when you have to change the battery and your hands aren't very nimble it's a little bit of a chore and the battery is pretty small, I might try one that you can charge up.
