Hearing aid batteries, tubes, drying jars, cases and accessories.
Hearing aid accessories help keep your hearing aids working properly, fitting comfortably, and lasting longer. Some accessories, such as cleaning tools, tubes, domes, filters, canal locks, chargers, and drying products, are used for everyday care, while others are replacement parts that may need changing over time.
This guide explains the most common hearing aid accessories, what each one does, and when you may need to replace or use them.
| Accessory | What it does | When you may need it |
|---|---|---|
| Domes | Soft tips that sit in the ear canal and help hold the hearing aid comfortably in place. | When the fit feels loose, uncomfortable, or sound quality changes. |
| Tubes | Carry sound from a behind-the-ear hearing aid into the ear. | When sound becomes weak, distorted, or the tube becomes stiff or blocked. |
| Tube cleaning pin | Helps clear wax, moisture, or debris from compatible hearing aid tubes. | When a tube is blocked or sound becomes weak or muffled. |
| Wax filters or guards | Help protect the hearing aid from earwax and debris. | When sound becomes quieter or the filter looks blocked. |
| Canal locks | Help keep compatible hearing aids sitting securely in the ear. | When extra retention is needed for models such as the Jaspa 3 Dura or Diamond Stream 12. |
| Cleaning tools | Help remove wax, dust, and debris from hearing aids and ear tips. | For regular maintenance and clearer sound. |
| Drying jar and drying tablets | Help absorb moisture from hearing aids when they are not being worn. | For overnight storage, humid conditions, or people who notice moisture build-up. |
| Chargers and charging cases | Recharge lithium-ion hearing aids without disposable batteries. | For rechargeable hearing aid models. |
| Storage cases | Protect hearing aids when they are not being worn. | When travelling, sleeping, or keeping hearing aids safe from damage. |
Open domes have small holes or vents that let natural sound and air pass through the ear canal. They usually feel less blocked and are often used for milder hearing loss, especially when low-frequency hearing is still fairly good. Closed domes seal the ear canal more than open domes. This can give the hearing aid more control over sound and reduce feedback or whistling, but they may feel more blocked or “full” in the ear.
Hearing aid domes are soft silicone tips that attach to the end of some hearing aid tubes or receivers. They sit inside the ear canal and help keep the hearing aid secure while allowing sound to enter the ear comfortably.
Domes can affect comfort, fit, feedback, and sound quality. If a dome is too small, the hearing aid may feel loose or whistle. If it is too large, it may feel uncomfortable or blocked.
Domes should be replaced if they become damaged, loose, discoloured, uncomfortable, or difficult to clean. Regular replacement can help maintain comfort and sound quality.
| Dome type | How it feels | Best suited for |
|---|---|---|
| Open domes | More natural and breathable, with less blocked-up feeling. | People with milder hearing loss or good low-frequency hearing. |
| Closed domes | More sealed, with stronger sound delivery and less sound leakage. | People who need more amplification or better feedback control. |
Hearing aid tubes are commonly used with behind-the-ear hearing aids. They carry sound from the hearing aid body into the ear. Over time, tubes can become blocked with wax or moisture, or they may harden and affect sound quality.
Depending on your hearing aid model, tubes may be available in various lengths for the most comfortable fit.
If your hearing aid sounds weak, muffled, or inconsistent, the tube may need cleaning or replacing.
Hearing aid tubes are almost always model-specific, so it is important to choose tubes that are compatible with your exact hearing aid. Standard tubes, slim tubes, and RIC tubes are not interchangeable. In particular, RIC tubes should only be used with RIC hearing aids, as they contain the receiver/speaker component and are not designed for standard behind-the-ear hearing aids.
Standard hearing aid tubes and RIC tubes look similar, but they are designed for different hearing aid styles and should not be used interchangeably.
Use a tube cleaning pin to gently clear wax, moisture, and debris from compatible hearing aid tubes to help restore clearer sound.
A tube cleaning pin is used to help clear wax, moisture, or debris from compatible hearing aid tubes. If a tube becomes blocked, the hearing aid may sound weak, muffled, or as though it has stopped working.
Tube cleaning pins are most useful for behind-the-ear hearing aids with removable tubes. Always remove the tube from the hearing aid before cleaning it, and avoid forcing the pin into any part of the hearing aid body.
Cleaning pins are not suitable for RIC hearing aids, since the tube is protected from buildup by a wax guard instead.
Wax filters, also called wax guards, help protect hearing aids from earwax and debris. They are especially important for in-ear and RIC hearing aids, where the sound outlet sits close to the ear canal.
A blocked wax filter can make a hearing aid sound quiet, muffled, or as though it has stopped working. Replacing the filter is often one of the first things to check before assuming the hearing aid needs repair.
Hearing aid wax guards will usually be attached to a special tool that is designed to make replacing your wax guards simple.
Although not required for most users, hearing aid canal locks may help hearing aids fit more securely.
Canal locks are small retention pieces that help keep compatible hearing aids sitting securely in the ear. They can be useful if a hearing aid feels loose, shifts during the day, or needs extra support for a more stable fit.
PocketAid canal locks are used with compatible models such as the Jaspa 3 Dura and Diamond Stream 12. They are designed to improve retention without making the hearing aid feel bulky.
Cleaning tools help remove wax, dust, and debris from hearing aids, domes, tubes, and sound outlets. Regular cleaning can improve sound quality and reduce the chance of blockages.
A hearing aid cleaning brush helps gently remove wax, dust, and debris from domes, tips, and sound openings to keep your hearing aids working clearly.
A drying jar and drying tablets help absorb moisture from hearing aids overnight, protecting small components and keeping devices dry between uses.
A drying jar is used to store hearing aids when they are not being worn, while drying tablets help absorb moisture inside the container. This can be helpful in humid weather, after long days of wear, or for people who notice moisture build-up around their hearing aids.
Keeping hearing aids dry can help protect small components and reduce the chance of moisture-related issues. Drying tablets should be replaced as directed, as they become less effective once they have absorbed moisture.
Rechargeable hearing aids use a charger or charging case instead of disposable batteries. Some chargers need to be plugged into power, while others include a built-in powerbank for charging away from home.
Charging cases are useful for travel, overnight charging, and keeping hearing aids protected when they are not being worn.
For example, the Diamond Stream 12 includes a powerbank-style charging case that can provide up to three top-ups, making it easier to recharge while travelling or away from a wall outlet.
Hearing Aid charging cases are devices specific in most cases.
A travel case helps protect hearing aids and small accessories from dust, damage, and loss when you are away from home.
A storage case helps protect hearing aids from dust, damage, moisture, and accidental loss. This is especially useful when travelling, sleeping, exercising, or carrying spare accessories.
If you use rechargeable hearing aids, it is also worth keeping the charger or charging case in a consistent place so your hearing aids are easy to find and recharge each day.
The accessories you need depend on your hearing aid style. A behind-the-ear hearing aid may need replacement tubes, domes, a tube cleaning pin, and canal locks, while an in-ear hearing aid may need wax filters and careful cleaning. Rechargeable hearing aids need a compatible charger, while all hearing aids can benefit from safe storage and moisture protection.
| Hearing aid type | Most useful accessories |
|---|---|
| Behind-the-ear hearing aids | Tubes, domes, tube cleaning pin, cleaning tools, storage case, and batteries or charger depending on the model. Wax filters for RIC (Receiver in Canal) devices like the Diamond Stream 12. |
| In-ear hearing aids | Wax filters, cleaning tools, storage case, and replacement batteries if required. |
| Rechargeable hearing aids | Charging case, charging cable, cleaning tools, drying jar, drying tablets, and compatible domes, tubes, or filters depending on the style. |
| Jaspa 3 Dura and Diamond Stream 12 | Canal locks, domes, cleaning tools, charger, and drying accessories. |
Hearing aid accessories should be replaced when they become blocked, damaged, loose, uncomfortable, or no longer work as expected. Small parts such as domes, tubes, wax filters, and canal locks can affect comfort and sound quality, so replacing them at the right time can help your hearing aids perform better.
When buying hearing aid accessories, make sure the part is compatible with your hearing aid model. Domes, tubes, filters, canal locks, chargers, and spare parts are not always universal, so choosing the correct accessory is important for fit, comfort, and performance.
PocketAid offers replacement accessories for compatible PocketAid hearing aids, including parts and consumables to help keep your devices working properly.
Common hearing aid accessories include domes, tubes, wax filters, cleaning tools, tube cleaning pins, canal locks, drying jars, drying tablets, chargers, charging cases, storage cases, and replacement batteries.
Not always. Some accessories only fit certain hearing aid models, so it is important to check compatibility before buying replacement parts. More generic items such as hearing aid drying jars and tablets are usually safe to use with any brands or models.
A weak or muffled sound can be caused by wax build-up, a blocked filter, a blocked or damaged tube, a poorly fitting dome, moisture, or a low battery. Cleaning or replacing small parts may help.
Domes should be replaced when they become loose, damaged, uncomfortable, or difficult to clean. Replacement timing depends on use, earwax build-up, and hearing aid style.
A tube cleaning pin helps clear wax, moisture, or debris from compatible hearing aid tubes. It can help restore sound if the tube is blocked.
Canal locks help keep compatible hearing aids securely positioned in the ear. PocketAid canal locks are used with compatible models such as the Jaspa 3 Dura and Diamond Stream 12.
Yes. Rechargeable hearing aids usually need a compatible charger or charging case, along with cleaning tools and any replacement domes, tubes, canal locks, or filters used by that model.
Drying tablets are used inside a drying jar to help absorb moisture from hearing aids when they are not being worn. They are useful for overnight storage, humid conditions, or moisture-prone environments.
