What Are Hearing Aid Earmolds?

An earmold is a custom-made piece of plastic, acrylic, or silicone that fits snugly inside your ear canal and concha (the bowl of your ear). Its primary job is to channel sound from the hearing aid directly to your eardrum.

Unlike generic rubber domes that sit loosely in the ear canal, a custom mold is crafted from an exact impression of your ear. This ensures a secure seal, which is critical for directing sound efficiently and preventing feedback (that annoying whistling sound).

Hearing aid molds are typically used with Behind-the-Ear (BTE) or Receiver-in-Canal (RIC) styles. They are an essential hearing aid piece for individuals with specific types of hearing loss or unique ear shapes.

Most earmolds are made out of acrylic or silicone. Earmolds for hearing aids can also be made out of vinyl or plastic. Each material has its advantages and disadvantages. Materials like silicone and vinyl are durable but more expensive. Foam is comfortable and easy to keep clean, but it may be more prone to damage. Foam can be used for an emergency, such as when a patient loses an earmold. Foam is not used in a standard fitting.

Hearing Aid Earmolds vs Domes: Which is Right for You?

One of the most common questions our hearing care professionals receive is: "Do I need a custom earmold or a standard dome?"

While both serve the same basic function—delivering sound to the ear—they are designed for different needs.

Custom Earmold

Fit Style: Custom-molded to your unique ear anatomy.
Hearing Loss Level: Essential for moderate to profound hearing loss.
Ventilation: Can be vented, but provides a tighter acoustic seal.
Sound Quality: Delivers powerful amplification; keeps low frequencies (bass) intact.
Feedback Control: Superior seal prevents feedback whistling.

Hearing Aid Domes

Fit Style: A few standard sizes.
Hearing Loss Level: Best for mild to moderate hearing loss.
Ventilation: Open style allows natural airflow (prevents "plugged" feeling).
Sound Quality: Allows some natural sound to enter; low frequencies may escape.
Feedback Control: Higher risk of feedback at high volumes.

Why Choose Custom Earmolds?

Your hearing care professional may recommend custom earmolds if:

You have profound hearing loss: To get the volume you need without feedback, you need a tight acoustic seal that only a custom mold can provide.
You have a unique ear shape: If standard domes slip out or feel uncomfortable, a custom fit ensures your device stays secure.
You have dexterity concerns: Custom molds are often easier to insert and remove than tiny domes, making them a great choice for many users.

What are the types of hearing aid earmolds?

There are several hearing aid earmold types. The most common hearing aid earmold styles are full shell, skeleton, and canal.

A full shell earmold covers the entire concha (the bowl-shaped part) of your ear, similar to the in-ear monitors that musicians use. These are made by taking a mold of your concha, so they are customized to your ear shape. Usually, this type of earmold is made of hard plastic or acrylic. One advantage of full shell earmolds is that they stay securely in place and don’t fall out easily. They are recommended for people with mild-to-severe hearing loss.

Another type is a skeleton earmold. Hearing aids with skeleton earmolds are also designed to fit your specific concha, but these are not filled in (hence the name “skeleton”). These earmolds are typically made of acrylic or PVC and are less visible than full shell earmolds, making them a popular option.

A canal lock earmold is made using a mold of your ear canal. This style doesn’t work well for everyone since you need a specific ear canal shape in order for it to stay in place. However, because it sits further in your ear, it is easy to hide and is the most discreet option. This style is best for those with moderate-to-severe hearing loss and can be made from a variety of materials.

The Custom Fitting Process at Miracle-Ear

Getting a custom earmold is a simple, painless process performed by your local Miracle-Ear hearing care professional.

Your hearing care professional (HCP) will start by examining your ear canal to ensure it is clear of wax and healthy.

A soft, silicone-like material is gently placed into your ear. It sets in just a few minutes, capturing every contour of your ear canal and outer ear.

The impression is turned into a digital 3D model. Your mold is then fabricated using high-quality hypoallergenic materials—ranging from soft silicone to durable acrylic.

Once your mold is ready, your HCP will fit it to your hearing aid and ensure it sits comfortably in your ear.

Note: Miracle-Ear offers custom hearing aid earmold colors ranging from discreet skin tones to clear styles, allowing you to personalize your look.

Daily Care: How to Clean Hearing Aid Earmolds

Proper maintenance is key to the longevity of your device and the health of your ears. Because earmolds sit deep in the ear, they can collect earwax and moisture.

Inspect Daily: Check the opening of the earmold for wax blockage.
Wipe Down: Use a soft, dry cloth or a specialized hearing aid wipe to clean the surface.
Clear the Vent: Use a wax loop or brush (provided in your cleaning kit) to gently remove debris from the sound bore and vent.

If you have a Behind-the-Ear (BTE) model with a detachable tube and mold:

Gently pull the tubing to disconnect the mold from the hearing aid hook. Do not get the hearing aid body wet.
Wash the earmold and tubing in warm, soapy water.
Rinse strictly and dry completely.
Use an air blower to force any moisture out of the tube before reattaching it to the hearing aid.

Always consult your instruction manual or ask your Hearing Care Professional at your local Miracle-Ear center before detaching any parts.

Troubleshooting common earmold problems

On occasion, you may have to do some earmold troubleshooting. Here are a few common issues you could experience:

If this is happening, make sure your hearing aids are turned on and have working or charged batteries. Check to be sure that there isn’t any debris in the device. Try adjusting the volume and settings. If this doesn’t help, you may need to inspect your hearing aids to see if they are broken or damaged.

If your voice sounds muffled, this may need to be fixed with earmold modifications or circuit changes in your hearing aid. If your voice is too loud, your earmolds may need a larger vent.

This may be the result of your hearing aids not sitting properly in your ears. First, try removing them and re-inserting them. If you have a BTE hearing aid, check the tubing to be sure it’s still intact and doesn’t have any cracks. You may also want to try turning the volume down to see if this helps.

If you’re unable to fix the problem yourself, make an appointment with your hearing care professional and have them help you.

Frequently Asked Questions - FAQ

The price of hearing aid earmolds can vary based on the material, style, and technology level of the hearing aid they are paired with. Often, the cost of the custom earmold is bundled into the total price of your hearing aids. During your visit, your hearing care professional will provide a transparent breakdown of your options.

It’s generally recommended to replace earmolds every 1 to 2 years. Over time, the material can degrade, discolor, or crack. Additionally, your ear shape can change slightly over time, which may loosen the seal and cause feedback. If your hearing aid starts whistling or feels loose, it might be time for a new impression.

The best hearing aids for custom earmolds are typically Behind-the-Ear (BTE) or Receiver-in-Canal (RIC) models. These styles offer the power needed for significant hearing loss while keeping the sensitive electronics outside the ear. Miracle-Ear offers a range of cutting-edge technology compatible with custom molds, including our ENERGY™ and CONNECT™ lines.
