The MDHearingAid®Story
The MDHearingAid® was invented by a board-certied Ear, Nose, & Throat
physician in Chicago, IL. He would encounter patients in his daily practice
who would benet from hearing aids, but many simply couldn’t afford the
thousands of dollars often needed to pay for them. As a physician, he knew
the effects of untreated hearing loss: depression, social isolation, anxiety,
and symptoms consistent with Alzheimer’s dementia.
He set out to nd a reasonable solution that could help with the most
common types of hearing loss at a reasonable price. He was looking for a
“one-size-ts-most” hearing aid similar to reading glasses that can easily be
purchased at the drug store.
After evaluating numerous hearing aids and sound ampliers below $200,
including those seen on television, he found, without fail, that almost all of
these were found to only amplify bass / low frequencies (<1000 Hz) and
were not useful in amplifying the frequencies related to the human voice
(1000-4000 Hz).

3
He then created the MDHearingAid PRO® to exact technical specications, so
that the range of sounds associated with the human voice would be amplied,
without overly amplifying background sounds.
The MDHearingAid PRO®hearing aid has been rigorously tested by leaders
in the hearing loss eld (ENT Physicians and Audiologists) who have
unanimously agreed that the sound quality and output is surprisingly accurate
given its low cost.

Cut the tube here
Your hearing aid comes with clear tubing that connects from
the ear hook to your ear canal. Also, there are various sizes
of ear plugs designed to t most adult ears. You will NEED
TO CUT the long tubing to the correct length for your
ear as described below. If you do not cut the tubing, the
hearing aid will NOT FIT properly.
Cutting the Tube
Connect the tube, elbow, and ear plug. The correct length of
the tubing is determined by how much needs to be trimmed
so that the tubing is relatively straight and not kinked. We
recommend cutting a small amount (1 mm or 1/16th of an
inch) at a time so that you do not cut the length too short.
Assembled Hearing Aid
Attach the long portion of the clear tubing to the tip of the
ear hook. Using your thumb and rst nger, hold the tubing
at the tip of the ear hook and twist back and forth until the
tubing slides OVER the hook tip. Ensure the “mushroom”
portion of the tip points INTO THE EAR CANAL.

6
Placing the Hearing Aid in Your Ear
Choose the appropriate size of ear plug for your
ear so that the t is snug. If the t is loose, you
may hear a whistling noise when the hearing aid
is on. Also, make sure that the plug does not slip
off easily, or it could become dislodged in your ear
canal.
Gently pull the outer ear backwards and upwards
with the one hand. With the opposite hand, insert
the ear plug into the ear canal, slowly twisting
back and forth while holding the lower part of the
tubing until the ear plug ts securely in the ear
canal.
Once the ear plug has been inserted, place the
hearing aid behind the ear so that the hook rests
comfortable on the ear, close to your head. When
the hearing aid is in its correct position, turn it on
and adjust the volume.

7
Correct Final Position
Once the hearing aid is tted correctly, it will sit on your
ear as in the picture.
If you cannot obtain a secure t or would like a more
precise t, you may want to consider having a Custom
Earmold made. Custom earmolds are shaped to the
exact contour of your ear and ear canal, providing the
best t possible.
Consult a local Audiologist or Hearing Aid Dispenser for a
custom earmold to attach the MDHearingAid®PRO hearing
aid. Alternatively, you can contact MDHearingAid Customer
Service ([email protected]) to learn
about other channels for obtaining a custom earmold.
NOTICE the
earhook rests on
the FRONT and
TOP of the ear.
To avoid whistling or “feedback”, make sure the earplug ts securely in the
ear canal. Try the different sized ear plugs to see which ts best. With a secure
t, there will not be whistling (you can see this by covering the earplug opening
with your nger and the whistling should cease).

8
Changing the Battery
You will need to insert a new battery to start using your
hearing aid.
Before inserting a new battery into the hearing aid,
remember to remove the adhesive tab. Do not use
batteries on which there is a sticky residue from the tab or
other unwanted substance as this can block the battery
airholes.
Push the nail grip downwards to swing open the battery
compartment. The nail grip is located below the power
switch at the bottom of the hearing aid.
Tip: Use the magnet in the end of the brush to simplify
battery removal and replacement.
The battery must be placed with the plus (+) sign
in accordance with the plus (+) sign on the battery
compartment. If the battery compartment does not close
easily, the battery is inserted incorrectly.

9
When removing an exhausted battery, make sure to hold the hearing aid over
a table, and turn the hearing aid over. The battery will fall out.
Recommended Battery Type
The MDHearingAid PRO®uses size 13 / 13A zinc-air batteries. Please note
the expiration date on the battery. Also, do not leave exhausted batteries in
the hearing aid, as they may leak and damage the hearing aid.
The life of the battery depends on a number of factors, such as the settings
of your hearing aids and the number of hours used per day.
In rare cases, a new battery may be exhausted because it was not sealed
properly. If your hearing aid does not work after replacing a battery, try
inserting a different new battery.
Remove the battery from the hearing aid if it will not be used for a prolonged
period of time.
Caution! Batteries can be harmful if swallowed. Be sure to keep
batteries out of reach from children and pets. If a battery is accidentally
swallowed, seek medical attention immediately, or call The National
Battery Hotline collect at 202-625-3333.

Turning the Hearing Aid On
“O” indicates the hearing aid is powered off
“N” normal amplication of low, mid, and high
frequencies. Use this setting if you have hearing loss
in all frequencies (“at” loss).
“H” amplication of predominantly mid and
high frequencies, with less amplication of low
frequencies and reduction of background noise.
Use this setting if you have a “sloping” hearing loss.
Try both settings at various volumes to see which
combination works best for your hearing loss.
CAUTION! This hearing aid can amplify loud and soft sounds. Do not
turn the volume past 2 unless you have severe hearing loss. Permanent
hearing loss may occur if used at high volume around a loud noise.
WHISTLING will be heard if the hearing aid is turned on but not securely in
your ear. This is normal. Once the hearing aid is properly seated in your ear,
the whistling will stop (read on).

Getting the Most from Your Hearing Aid
Your satisfaction with hearing aids depends on the type and degree of your
hearing loss and your expectations. No hearing aid can restore the normal
hearing of our youth, including those costing thousands of dollars.
However, you can maximize the return on your investment by understanding
the 3 keys of hearing aid happiness:
Patience
Balance Fit

12
Patience
A new hearing aid can be a big adjustment. Your brain has to relearn how to
hear and listen—in many cases to sounds it hasn’t processed in years.
The amazing thing is that it still can—all these years later but it takes time and
practice. In fact, medical studies have shown that your brain requires several
weeks to adjust to your new hearing environment and become accustomed to
your new hearing aids. During this time:
• You may initially notice lots of background sounds. These have almost
always been a part of your environment, and in time you will tune out many
of them and not notice them.
• You may nd that a quiet environment is more comfortable in the beginning
of the adjustment period. Gradually introduce new listening environments
as your ears become accustomed to the hearing aids.
• The addition of new sounds in your life can be overwhelming to some
people. Try wearing your hearing device for a short period each day and
gradually extend the time that you wear them.

• If you are a new to hearing aids, be aware that there will be sounds
that you may not have heard in a long time. You will be able to tune out
background noise in a short period of time.
• In noisy environments, you may nd it easier to understand speech by
facing the speaker. Focus on reading lips and observing facial expressions
and body language.
• Your own voice may sound too loud. This is very common for new hearing
aid users, but most people get used to it over time.
• You may also feel plugged up or feel like you’re talking in a barrel. This
“occlusion effect” is a normal reaction to wearing new hearing aids, and the
sensation will usually go away in the rst few weeks.
Using a hearing aid takes practice and patience. Some people adjust very
quickly, and most adapt within a few weeks. Please do not give up prematurely.

14
Balance
We are born with 2 ears for a reason. It is best to maintain balance in treating
hearing loss. If you have hearing loss in both ears, medical studies have
shown that you will get far greater satisfaction and the BEST results by
wearing 2 hearing aids for the following reasons:
1. Signicantly better understanding of speech and conversation, since the
brain is receiving a balanced signal from both ears
2. Less overall background noise amplication
3. Better hearing and understanding in noisy situations
4. Better localization of the direction of sounds
5. Listening will be more pleasing and effortless and less frustrating
6. Sound is balanced and more natural, especially music
7. Less chance of feedback or whistling from your hearing aids

8. Less tinnitus (ringing) in the ears when wearing 2 hearing aids
9. An overall improved quality of life when wearing 2 aids as compared to
people wearing only one
If you have hearing loss in both ears, but only ordered 1 aid, we strongly
encourage you to try one aid in each ear. Use the enclosed coupon for a
discount on your second aid. As always, you have a 45 day risk-free trial and
100% money-back guarantee.
Fit
Hearing aids, no matter how expensive, are almost useless if they don’t t well.
Without a proper t, it is impossible to reap the full benet of your investment.
•It is important to cut the tubing to the right length. Tubing that is too long will
not allow the ear dome (tip) to seat properly in the ear canal. Make sure the
hearing aid tubing is sized as shown on Page 5.
•Your hearing aid comes with 5 different sizes of silicone ear domes.
Choose the appropriate size of ear dome (tip) for your ear so that the t
inside the canal is snug. If the t is loose, you may hear a whistling noise
when the hearing aid is on.

16
•It can take time for a hearing aid to feel comfortable. Try wearing it for 30-
60 minutes a day at the beginning and gradually extend the time that you
wear the hearing aids.
•You may nd that you require a different size dome once your ear has
adjusted to wearing a hearing aid regularly.
•If your hearing loss is mild to moderate, you may consider the optional
open-t tubing and domes which can help reduce a plugged ear sensation
even more (see optional accessories, page 20)
•For a more precise t, consider customer ear molds. These can
be obtained from a local Audiologist or Hearing Aid Dispenser.
Alternatively, you can contact MDHearingAid Customer Service
([email protected]) to learn about other channels for
obtaining a custom earmold.

Using the Telephone
If your hearing aid whistles while using the telephone, try various positions
with the telephone receiver, until you discover the arrangement that works best
for you.
1. Use the phone with your hearing aids in the regular “on” position.
2. Try holding the telephone near the hearing aid microphone at the front and
top of your ear.
3. Also try holding the phone behind your ear, below your ear, or angled such
that the phone receiver is tilted and open forward.
4. Of course, the speaker phone function will work well with hearing aids.
