DO NOT buy a set of Nano CIC hearing aids…
Buying a set of Nano CIC hearing aids for $247 on 5/12/2023 with order #570018, I was assured by the Nano Customer Service that if it didn't work, they had an advertised full refund policy if returned prior to 45 days. I tried the aids but they were more like amplifiers than good hearing aids (along with multiple other quality problems), so I requested to send them back on May 19. I received the necessary RMA codes and directions for the return process. I soon received a mailing label with USPS tracking number and shipped them on 5/30, receiving an email on 6/1 that they had been received. I also photographed the products and shipping containers with papers, as many Nano reviewers warned people to do so. However, 13 days later, only after my request for a status update, on 5/13, I received an email that they had denied my refund request due to damage to the product, with a picture so blurry, I can't see the imperfection they claim. Then even after I rejected their product, they tried to sell me another replacement pair for a $79 fee! I wore the hearing aids as provided for only about 2-3 days per their instructions and kept them in their special protective package. Upon packing for shipping back to Nano, they were in the exact same condition as I had received. I have photos of the hearing aids I packed away with the original packing box and papers. Many other reviews & complaints I've read about on Nano show this exact same problem suggesting to me that if they were truly damaged as described, then Nano should review how their refund department handles all these returns. I have learned that Nano seems to look for different ways to deny requested refunds which hurts their reputation as a truthful and helpful company. I am sorry to have to write this complaint in the first place, but I'm simply asking for my refund of $247. Perhaps this will help warn other people about this company. I have learned that this Nano company has an F rating by the BBB, and is not accredited by the BBB. Nano also has a 1-star review rating! Even though they have a CA address they have NO CA business license. The company uses a residential address as it's corporate address but it does not exist. All of this leads me to say BEWARE of NANO!

semi-deceptive
To start with, it takes ONE phone call to make an order, but a call, plus a call-back to make a return? And then, lots of jabber-jabber about up-grading, etc, etc, but pretty useless to us, as I hated these hearing aids! I sure hope my return will be as easy-peasy as getting these things!

Can't get rid of the screeching
Can't get rid of the screeching. I've tried different domes, but I still get feedback
Response from Nano Hearing AidsJun 23, 2023
Hello Brian,
Squealing or feedback can occur for many different reasons. We have provided some of the more common reasons below to help you troubleshoot your issue:
1. Check for ear wax: earwax build-up is a common cause of acoustical feedback. When a sound wave hits a solid block of earwax, that sound wave shatters, sending sound every which-away including back out the ear to get re-amplified by the hearing aid microphone.
2. Check the fit: A loose-fitting hearing aid allows amplified sound waves to escape the ear canal around the hearing aid, reach the mic and off we go again in a feedback loop.
3. Speaker Placement: If the direction of the receiver is off and pointing directly into the wall of the ear canal, it can cause the amplified sound to bounce back into the hearing aid and the whistling begins.
4. Hearing Aid damage: The sound tube may become damaged over time by aggressive cleaning, the mic may have gotten pushed in, or there could be a crack in the hearing aid casing.
If this doesn't help or if you need further assistance, please reach out. You may call customer service at 619-738-2438 or email us at [email protected]. You can also try our Live chat at www.nanohearingaids.com.
Have a great day and stay healthy!

Awful!!!
Awful!!!! I ordered the hearing aids...You had the wrong address on the shipment.....the aids were sent back to YOU and you sent me and email that stated that the hearing aids were DELIVERED TO ME!!! How bad is that. The worst part...I called when I could see by the tracking that they were sent back to you...the rep said she was shipping another pair.....that we would get them within a couple of days....and that she would CALL ME to make sure I got them.....guess what...NO AIDS SHIPPED....NO PHONE CALL....I'M THINKING THAT THIS IS A SCAM.
