I have had another popular brand for 8 years at a cost or $6700.00 for a pair. I bought a nano set last year. I saw the sigma and bought them for the ability to do a hearing test with my phone. I love them the adjustment was easy. They are as good as my popular band. I couldn't be happier. The cost was10% of my original set. I can readjust my settings if needed without going to the store and having them adjust them. The battery also are lasting a lot longer than my original aids. I recommend these to any one who spent the large sum of money as I did,the nano results are as good as the $6700.00 pair

Hello my name is BILL I’m a 67 year old Project Manager for a masonry company in the Rocky Mountains in Western Idaho. After 30 some years of being subjected to high decimal screem of Block and Stone saws, Heavy equipment ect. My hearing was deteriorated to the point that I heard maybe half of what was said to me if there was any other sounds going on in the background. Watching TV was a irritating exercise as I was always asking my wife, what did they say?? Read the reviews on the Nano Hearing Aides, all were highly encouraging and promising. After talking with the friendly helpful Customer Service person at Nano she helped with my decision to buy the Sigma Model featuring the IPhone App and all it brings to the Hearing Aide experience. Sigma Hearing Aides Arrived and afternoon taking the Hearing Test in the App and hitting the optimize button the App set the hearing parameters automatically based on the test. After I fine tuned the tonal parameters to my liking I was amazed. I experienced sounds I hadn’t heard in decades, the crumpling sound when you wade up a piece of paper, the snapping sound when you pulled open a soda can tab.
Also my voice was unusually loud and kinda irritating sounding like I was hearing myself through a pipe. I read and all the minor negative side of the experience was listed and explained in the pamphlet that came with the Sigma. It went in to explain your brain needed time to adjust to the new sounds and explained you need to wear them for a couple weeks for your brain to settle in to the new noises it was experiencing. After less than a week my voice went back to sounding normal and not unusually loud, all the strangeness of the other sounds settled into a normalcy that was comforting and pleasant. Now I’m not claiming that decades of abusing my hearing was wiped away, what I am saying is I now have to tell my wife, honey.... why are you yelling I’m right here, we both will laugh because now she has to relearn how speak in a normal voice to me as opposed to years of having to talk to me like I was 50 feet away.
Thankyou!
Nano

Better than expected. Voices are clear and natural sounding. So comfortable I forgot they were in. (Not recommended for the shower!)

It took me a while to open the box, read instructions and proceed with start-up:
1. insert batteries + install domes; ok
2. try out; there was some feed-back, especially the right ear
3. changed the domes to larger ones, left ok, right still had feed-back.
4. installed largest dome right, feed-back gone, hearing aid prone to pull out; need a little longer sound tube
5. installed Nano App on my cell phone
6. did a hearing test left + right, worked fine, but some channels right maxed out on volume
7. the nano app is the best feature I have seen so far. It permits some fine tuning without having to see an audiologist
8. I would like to have a little more volume on the Nano Sigma + I really need a longer sound tube
9. Since I am forgetful and previously lost hearing aids, I went on Ebay and found + ordered a clip-on tether, works ok
11. overall I am happy, so far

Easy to use work great

I was impressed with how easily the Nano was programmed. Works very well with medium hearing loss. Would buy again with the BOGO offer.

It was easy to set up using the Nano app.
I have been using it for a couple of weeks and find it easy change the batteries than I thought.
once I found the best settings for me I can hear a lot better than before.
When I was looking for hearing aids the price was something I could afford, which made a big difference.
I was impressed with the hearing test in the app and the ability to change according to situation, driving, outdoors, conversations and watching TV.
I am sooo glad I chose them thy have made a difference in my daily life.

Only had them a couple of weeks but getting along great now. It took a while to get them adjusted with the app. I am doing great now and can hear things i haven't heard in years. Great hearing aids for the price. Thanks Nano

Elizabeth was well-informed regarding my issue. She listened patiently and immediately took steps to resolve my concern. With a friendly and pleasant attitude she took responsibility for the issue rather than suggesting that it may have been my error. The process was very
efficient and I was very pleased with the interaction and the quick resolution of my concern. I would highly recommend this company to those interested in purchasing any of their products. This was impressive service!

I know what I am talking about. I am an inventor and 20 years years ago and ever since I have been telling audiologist that frequency controls should be able to be adjusted by the customer using their smartphones. Told them I was never going to buy one until this was available. NANO has gone way past what I thought would be possible. WOW, all I can say is THANK YOU for making my dream come through. I personally will be selling for you a lot of hearing aids. I should be getting a Commission. LOL 😂
