What is the difference between an FDA Registered hearing aid and an FDA Approved hearing aid?

Air conduction hearing aids, such as the MDHearingAid PRO and AIR are Class I medical devices. Owners or operators of businesses that produce and distribute Class I medical devices intended for use in the U.S. are required to register annually with the FDA. This process is known as establishment registration.

FDA approval means that the FDA has decided the benefits of the approved item outweigh the potential risks for the item's planned use. This term is more commonly applied to drugs and medical procedures than Class I medical devices. Only FDA Registered hearing aids meet or exceed federal standards for Class I medical devices.

A PSAP, like the ones found on Amazon, eBay, in drug stores and seen on late night TV may make everything equally loud and not have the frequency shaping needed for most hearing loss. In contrast, hearing aids are Class I medical devices, subject to a higher level of federal regulation, and programmed with different frequency responses to fit a wide range of hearing loss.


What are common signs of hearing loss?

If you find yourself turning up the volume on the TV or radio, frequently asking people to repeat themselves, have trouble hearing women and children speak, feel drained and stressed by trying to keep up with conversations around you and/or having a persistent ringing in your ears, you may have some degree of hearing loss.


What are some causes of hearing loss?

The causes of hearing loss are varied. Everything from aging to illness or ototoxic drugs used to treat cancer, heart disease and high blood pressure to loud noise in the workplace, explosions or head trauma experienced while playing contact sports or serving in the military, the roar of the crowd in indoor arenas or extended ear bud use while listening to music can cause changes to your hearing.


Which hearing aid should I buy?

The MDHearingAid AIR is our most popular all-digital hearing aid. For most users, the AIR will be the best choice as accommodates the most common types of hearing loss in the most common listening environments. The AIR offers superior sound quality, fit, and comfort, and also includes a Telecoil that allows for wireless use of a landline and compatible cell phones. The AIR is full of features found on hearing aids that can cost up to $3500 each. If you have worn custom hearing aids before, you will find that the AIR’s performance equals or exceeds the performance of your prior aids.

The MDHearingAid PRO hearing aid is our longest selling model. It is a premium analog Behind-the-Ear hearing aid built with medical-grade components. It has an easy to use Volume Dial and 2-Program Switch to decrease background noise, allowing you to control your experience. If price is the overriding consideration, the PRO is the best choice.

Can I do a hearing test over the phone?

It is fast, safe and easy to do a hearing test over the phone, however, all telephone tests for hearing screening are NOT the same. When telephone hearing screenings use pure tones (such as those used in hearing tests at a clinic), the loudness of the tones cannot be reliably controlled; consequently, your hearing ability cannot be properly assessed. In contrast, the National Hearing Test uses a Digits-In-Noise test (that is, spoken digits in a background of noise), which is largely unaffected by the loudness (within the typical loudness range of telephones).

For the most reliable results, we recommend that you do not use a cell phone for the test. Cell phones often have poor or unreliable connections that introduce unpredictable amounts of distortion. Failing the test on a cell phone would not be a clear indication of a hearing problem.


How do these hearing aids compare to custom hearing aids?

Custom hearing aids provide the highest level of care that you can get, but that level of care can come with a pricetag that can exceed $5000 per ear! If price is no object, Dr. Cherukuri recommends you pursue a custom hearing aid. However, for most people, custom hearing aid costs are a significant barrier to better hearing.

That's why Dr. Cherukuri and his team of audiologists evaluated thousands of hearing tests before developing the amplification profiles built into each MDHearingAid.  Advanced digital technologies plus convenient volume dials and program selection buttons give you a hearing aid experience that rivals the most expensive hearing aids for a mere fraction of the cost.

How will I know if hearing aids will work for me?

All MDHearingAid models are programmed to meet the needs of most people with hearing loss. Many of our customers have told us their MDHearingAid has been life changing. The best way to see firsthand how much they will help you is to try them in the comfort of your home, risk free. Your satisfaction is guaranteed! 

If you have had a hearing test in the past, you may email it to us at support@MDHearingAid.com or fax it to 800-937-5970 so our physicians, audiologists, or hearing instrument specialists can provide you with specific guidance on the best aid for your needs for FREE.

Every person’s hearing loss will be different as is every person’s ability to rehabilitate their hearing with hearing aids. Your satisfaction with hearing aids depends on the type and degree of your hearing loss and your expectations. No hearing aid, regardless of price, can restore the normal hearing of youth.

To get the best result, understand that it can take your brain about 21 days to get used to the sound of new hearing aids. Many sounds may seem too loud at first, but your brain quickly accommodates so that these are more comfortable.

 Many people benefit from a little support during their initial trial period. MDHearingAid offers FREE 1-on-1 consultations with a licensed hearing instrument specialist after your purchase to help you get the best possible results from your new hearing aids.

Should I buy 1 hearing aid or 2 hearing aids?

The brain processes signals from both ears for improved clarity and balanced sound. If you have hearing loss in both ears you will be able to hear much better with two hearing aids, and your satisfaction with those hearing aids will be much higher. If you only use one hearing aid, but have hearing loss in both ears, your brain has to process two different sound and clarity levels, which makes the sound signal more difficult to understand.

Can I use a hearing aid with eyeglasses? 

Of course! Many people successfully wear both eyeglasses and hearing aids. For best results, put your glasses on. Place the hearing aid body between your glasses and your outer ear. To avoid problems when removing your glasses or putting them back on, resist tilting your glasses up or down as you take them off or put them on.

Can I wear a nasal cannula (or oxygen tubing) with a hearing aid?

Yes. Many of our customers successfully use supplemental breathing tubes or nasal cannulas and wear hearing aids. After securing the hearing aid body behind your ear, drape the tubing over the ears as you normally would. Secure the cannula tubing in the manner that you prefer. Some experimentation might be necessary to find the best way to wear your hearing aid, oxygen tubing, and/or eyeglasses, but the rewards are worth it.

What do you mean by “One-Size-Fits-Most”?

The MDHearingAid AIR and PRO hearing aids accomodate various sizes of clear tubing, tips and ear domes that connect the hearing aid to your ear. By combining these elements, our aids can fit most adult ears comfortably. Additionally, all MDHearingAid models come pre-programmed to meet the needs of most people with hearing loss.

What about children with hearing loss?

Our products are not for use by anyone under 18. 

In addition to seeing a physician for a medical evaluation, a child with hearing loss should be directed to an audiologist for evaluation and rehabilitation. Hearing loss may cause problems in language development, educational growth, and social growth for a child. An audiologist is qualified by training and experience to assist in the evaluation and rehabilitation of a child with hearing loss.

What if my hearing aid doesn’t fit my ear well?

With hearing aids, like shoes, fit is everything. A good fit is critical to your hearing aid feeling comfortable in your ear and providing good, quality sound with minimal feedback. MDHearingAid has a number of options available for all hearing aid models to enable you to achieve a great fit. 

However, if after several days of experimenting with the options that came with your aid, you are still not able to achieve an optimal fit, please email MDHearingAid support at support@MDHearingAid.com 24/7 or contact one of our Hearing Aid Specialists at 312-366-3899, Monday - Friday, 8:30 a.m - 4:30 p.m., Central Standard Time. Our customer support specialists will be able to advise you on how to get the best fit from your particular model or may be able to provide you with additional sizes and shapes of tips, ear domes or tubing to better suit your needs.

If a more precise fit is desired or required, the MDHearingAid AIR and PRO can be fitted with a custom ear mold. A custom mold can be obtained from an online store or from a local audiologist or hearing aid dispenser.

Will insurance cover hearing aids?

Most of the time, insurance policies and Medicare do not cover the cost of, nor reimburse for, hearing aids and most Americans pay out of pocket for hearing aids. In fact, expense is the main reason most people who need hearing aids go without them. MDHearingAid was founded so those who couldn't afford thousands of dollars for hearing aids could get the high quality hearing aids they needed, affordably and without hassle.

If your insurance policy does cover hearing aids, please contact us and we'll be happy to provide you with the documentation necessary to submit a claim.

Can I finance my hearing aids?

Of course. During the checkout process, simply select either the Affirm or PayPal payment options.

Will a hearing aid cure the ringing in my ears?

Ringing in the ears, or tinnitus, is most commonly caused by nerve-related hearing loss. Our hearing aids will not cure the ringing in your ears, but the ringing will become less noticeable when you are using the hearing aid.

Back to Top >


What type of batteries do hearing aids use?

The AIR and PRO hearing aids use size 13 hearing aid batteries (orange tab)

The LUX hearing aid use size 312 hearing aid bateries (brown tab)

The FIT hearing aids (no longer sold) use size 10 hearing aid batteries (yellow tab).

Both sizes of hearing aid batteries are readily available at most corner drug stores. You can also order the correct battery for your hearing aid from us here.

What is the warranty?

Your MDHearingAid is covered against defects in materials and workmanship for 90 days from the time you receive your order. If, at our examination, it is determined that the unit failed to work due to parts, materials or workmanship we will repair or replace it for free.  

With an MDShieldTM Protection Plan, you are 100% protected from ALL types of accidental damage, or anything else that may go wrong with the aid, including things not covered by the standard Warranty (water damage, battery corrosion, stepping on the hearing aid, etc).  The MDShieldTM Protection Plan is the most comprehensive hearing aid protection plan on the market.

How long will my hearing aid last?

As long as hearing aids are kept clean and dry, they can last many years. We have many customers who are still using the MDHearingAid model they purchased over 5 years ago! However, most hearing aids ultimately fail due to exposure to excess moisture, dirt, or accidents. 

With new digital technology advances, hearing aids like the MDHearingAid AIR are similar to computers or cell phones. They don't really wear out, but after 3 or 4 years, you may find that you want to upgrade because of newly available features and technologies.
 


What is the Return Policy?

Your satisfaction is guaranteed. If you are not satisfied with your MDHearingAid, you have 45 days from the date of purchase to return it for a full refund.

MDHearingAid requires a minimum trial period of 21 days. This minimum trial period is required because medical studies show that your brain requires about three weeks to adjust to new hearing aids. Return requests prior to 21 days from date of invoice will incur a ten percent (10%) Early Return Fee.

All products MUST include a Return Merchandise Authorization (RMA) number for proper processing. Products returned without a RMA number will incur a twenty percent (20%) No-RMA Fee.

Please email support@MDHearingAid.com for a RMA number and specific return instructions. We are available 24 hours a day, 7 days a week (a calendar day equals a business day). Or you may call Customer Service, 312-366-3899, M–F, 8:30 AM - 4:30 PM CST.

We are unable to honor return requests after 45 days from the date of purchase as shown on your invoice.

Do I need a prescription or medical evaluation before buying a hearing aid?

Federal law permits a fully informed adult to sign a waiver statement declining the medical evaluation for religious or personal beliefs that preclude consultation with a physician. Children under the age of 18 are not eligible for a waiver. The exercise of such a waiver is not in your best health interest and its use is strongly discouraged.

In accordance with good health practice, MDHearingAid and the US FDA recommend that a person with hearing loss have a medical evaluation by a licensed audiologist or physician (preferably a physician who specializes in diseases of the ear) before purchasing any hearing aid. If you have or think you may have any of the following conditions you should consult a doctor prior to purchase:

  • Visible deformity of the ear
  • Fluid or drainage from the ear within the past 90 days
  • Sudden, rapidly progressing, or fluctuating hearing loss
  • Spells of acute or chronic dizziness
  • Hearing loss only on one side that worsened in the past 90 days
  • Ear canal blockage, a lasting ear infection or a 'plugged up' fullness feeling
  • Excessive wax buildup, or a history of excessive wax buildup
  • Pain or discomfort in the ear
  • Ringing in one or both ears within last 90 days
