Choosing the Right Earpiece: The Domes vs Moulds Dilemma

When it comes to choosing the right hearing aid, there are several crucial decisions to make. One of the key choices is selecting the best type of earpiece for your needs. In the world of hearing aids, two popular options are domes and moulds. Each has its own set of advantages and considerations, making the choice between them an important step towards achieving optimal hearing performance and comfort. In this blog post, we’ll dive into the differences between domes and moulds, and help you understand which option might be more suitable for you.

Understanding Domes

Domes are the small, soft tips that attach to the end of the hearing aid’s tubing or receiver. They come in various shapes and sizes, offering different levels of comfort and fit. Domes are often a preferred choice for those with mild to moderate hearing loss or for those who are new to wearing hearing aids.

Advantages of Domes:

  • Comfort: Domes are generally lightweight and unobtrusive, making them comfortable for extended wear.
  • Easy Maintenance: They are easy to clean and replace, ensuring optimal hygiene and performance.
  • Ventilation: Domes allow for some natural sound to enter the ear, which can help users maintain a sense of their environment.


  • Fitting: Domes may not be the best choice for individuals with severe hearing loss or unique ear canal shapes, as they might not provide the level of amplification required.

Types of Hearing Aid Domes

There are several types of domes available, each designed to meet different needs:

  • Open Domes: These domes have openings that allow natural sound to enter the ear, suitable for mild to moderate hearing loss.
  • Closed Domes: These domes have fewer openings, providing more amplification and reducing feedback, ideal for moderate hearing loss.
  • Power Domes: These domes are fully closed and provide the highest level of amplification, suitable for more severe hearing loss.

Exploring Moulds

Moulds, on the other hand, are custom-made to fit the unique shape of the wearer’s ear. They provide a more personalised and snug fit, making them suitable for individuals with a range of hearing loss levels, from mild to profound.

Advantages of Moulds:

  • Precision Fit: Custom moulds are crafted to match the contours of the wearer’s ear, providing an excellent seal and amplification.
  • Reduced Feedback: Moulds can help minimize feedback or whistling sounds that might occur with improperly fitted domes.
  • Severe Hearing Loss: Moulds are particularly beneficial for individuals with severe hearing loss, as they can provide the necessary power and control.


  • Adaptation Time: Custom moulds might take some time to get used to, as they create a more significant presence in the ear canal compared to domes.
  • Maintenance: Moulds might require more careful cleaning and maintenance to ensure longevity and hygiene.

Types of Hearing Aid Moulds

Custom hearing aid moulds come in various types, each suited for different levels of hearing loss and preferences:

  • Full-Shell Moulds: These fill the entire outer ear and are ideal for severe to profound hearing loss.
  • Half-Shell Moulds: These cover only the lower part of the outer ear, suitable for moderate to severe hearing loss.
  • Canal Moulds: These fit within the ear canal and are less visible, suitable for mild to moderate hearing loss.
  • Skeleton Moulds: These have a hollowed-out design, providing a balance of comfort and retention, suitable for various levels of hearing loss.

Choosing the Right Option

The decision between domes and moulds ultimately depends on various factors, including your degree of hearing loss, ear canal shape, lifestyle, and personal comfort preferences.

Domes Might be More Suitable If:

  • You have mild to moderate hearing loss.
  • You prefer a more discreet and lightweight option.
  • You’re looking for ease of maintenance and replacement.

Moulds Might be More Suitable If:

  • You have severe to profound hearing loss.
  • You want a snug and personalized fit for optimal sound quality.
  • You’re willing to adapt to the feeling of a more substantial earpiece for better performance.
