*ZHONGDE ZDB-100A Hearing aid review from customer

15 yrs having not heard anything in my left ear. Tried these. Boop. I can hear everything. These do not have noise reduction. They amplify everything around you. So there's a learning curve to how to use them. You can adjust the volume to where you can hear adequately. But whatever is making the most noise in the room is what you're going to hear predominantly over everything else. These are not $1,000 hearing aids. They're not sold as such. But they do deliver exactly what they say they'll do. You know they're cheap. Because you didn't pay a lot for them. So know that when you buy them. They are a replacement for going to a hearing doctor and buy an expensive set of hearing aids. But they will get you by.
Now that I know there's Hope for hearing in my left ear. I will go to a specialist and let my insurance buy me the more expensive set. But this at least told me what I needed to know. That I'm not totally deaf in that ear.
UPDATE:
After several days of use I'm still happy with my product.
I will attempt to help you with the adjustment of these devices, in order to make it easier for you.
I only need this for one ear which I will refer to as my bad ear.
I cannot hear without it in my bad ear. I can hear perfectly fine with this device.
Setting the volume is a little tricky, and a lot of trial and error. I have found that by doing the following I can get the best results possible for me
Take your hands and hold them about three or four inches from your good ear and clap your hands.
Do the same thing with the device turned on and clap your hands about the same distance as you did and you're good here.
Adjust the volume knob up and down until what you're hearing through the device is close to the same sound that you're getting on your good ear.
Having these devices in both ears gave me a lot of echo and feedback. Fortunately I only need it for one ear.
About charging the device.
I admit and I did not read all the fine print and the instructions that came with these hearing aids or amplifiers.
They charge just fine in a few hours.
I tried to use the USB port on the side of my laptop as my power supply instead of plugging into an outlet. This did not work. So I only suggest using the power block that comes with these units to charge your devices with.
Without them I can virtually hear nothing in one ear. My setting is a little past the number one. Just before I get to 2.
They are very difficult to turn the volume up and down while you have it in your ear. You will need to remove it from your ear to properly adjust the volume.
. Periodically you may need to remove it to turn it up as the battery becomes weaker.
I suggest turning the unit on after it's fully charged from the charger. Allow it to sit for about 5 minutes before you attempt to adjust the volume. If you try to do it straight from the charger you will find that after about 5 or 10 minutes of usage you will need to turn it up a little bit. This can be eliminated by just waiting 5 or 10 minutes before you attempt to set the volume. Now that I have discovered this. I no longer need to make any adjustments to the volume before I use it. Only needing it for one ear I can use one device for several hours then put it back in the charger and then pick up the second device and start using it in its place.
This allows me to be able to hear perfectly fine all day all the way through till bedtime.
