As many as 48 million Americans suffer from hearing loss, but less than 20% of those use hearing aids, which are the main treatment for hearing loss. Unfortunately, the reason behind this is the high cost of traditional hearing aids and hearing healthcare, which creates a financial barrier and prevents access to those who need it.

Over-the-counter (OTC) hearing aids, such as those from Go Hearing, aim to combat this financial burden by enhancing accessibility and affordability for those with mild-to-moderate hearing loss. One brand of OTC hearing aids you may have come across is Nano, which offers four different hearing aids. In this article, we’ll take a look at some of their features and compare how they’re priced.

About Nano hearing aids

Nano hearing aids are over-the-counter (OTC) devices, and as is the case with most OTC hearing aids, they are not yet covered by health insurance providers. As with Go Hearing’s OTC hearing aids, you do not need to visit an audiologist for an examination, prescription, or fitting in order to purchase and use them.

Nano offers a range of four different hearing aids to choose from, including two completely-in-canal (CIC) models and two behind-the-ear (BTE) models. The CIC Recharge OTC hearing aid is an entry-level device, offering a simple, nearly invisible design with a manual push-button control scheme, while their flagship model, the Sigma Plus Bluetooth OTC hearing aids, offers a compatible phone app for control, as well as other advanced features.

The Nano hearing aids offering

The current Nano hearing aid lineup comprises four different hearing aids: a small CIC hearing aid (the CIC Recharge), a digital CIC hearing aid (the CIC Digital Recharge), a digital BTE hearing aid (X2 Recharge), and a smartphone-powered BTE hearing aid (the Sigma Plus Bluetooth).

All Nano OTC hearing aids come equipped with an internal rechargeable battery, and there is no option for a replaceable battery hearing aid.

Nano hearing aids support

Nano offers “free lifetime customer support” that is available 24/7, although there is no mention of whether the support team includes trained audiologists or hearing healthcare professionals. Nano also states that if you are not satisfied with your purchase within 45 days, they will issue a full refund.
