What is a Hearing Aid Canal Lock?

A canal lock is a small extension or protrusion on hearing aids that helps secure the device firmly in the ear canal.

It is made from soft, flexible material and extends from the body of the hearing aid to rest against a portion of the ear’s anatomy. The primary function of a canal lock is to prevent the hearing aid from moving or slipping out, especially during talking, chewing, or physical activity.

A canal lock is particularly beneficial for users with larger ear canals, soft ear tissue or those who experience device feedback due to a loose fit. Additionally, canal locks help maintain the correct positioning of the hearing aid, ensuring consistent sound quality and comfort.

You will find our instructional videos handy, as we explain how to remove the canal lock.

What is a Hearing Aid Wax Guard?

A wax guard is a small, replaceable filter used in many hearing aids to protect the delicate internal components from earwax, moisture, and debris.

Earwax is a natural and necessary part of ear health, but it can easily clog the tiny speaker or receiver openings in your hearing aid, leading to reduced sound quality, feedback or even complete malfunction.

The wax guard sits at the audio outlet of the device, acting as a barrier to catch wax before it reaches sensitive parts like the receiver.

Using a wax guard can significantly extend the life and performance of your device. They’re easy to change at home and should be replaced regularly, typically once every few weeks or when you notice a drop in sound clarity.

What is an Open Dome?

An open dome is a small, soft silicone ear tip that fits over the end of a hearing aid and sits inside your ear canal. Open domes are one type of hearing aid domes, which are essential popular for ensuring comfort and optimal sound quality in hearing aids. As the name suggests, it has multiple openings or vents that allow natural sound, like your own voice and background noise, to pass through.

An open dome helps prevent the “plugged ear” sensation and makes sound feel more natural, particularly for people with mild to moderate high-frequency hearing loss. Open domes are popular for first-time hearing aid users because they feel less intrusive, are more breathable and allow you to retain some of your natural hearing.

What Is a Double Dome?

A double dome consists of two overlapping silicone flanges or rings. This creates a tighter, deeper seal in the ear canal, helping to block out more external noise. Double domes are designed to prevent sound from leaking out and causing feedback (whistling), making them ideal for users with moderate to severe hearing loss.

By sealing off the canal more completely, double domes allow the hearing aid to deliver stronger amplification without distortion or squealing. They may take more getting used to in terms of comfort.

Do I need an open or double dome?

Choosing between an open dome and a double dome depends on your hearing profile, comfort preference and device type. Open domes are better if you want a light, natural feel and still have good low-frequency hearing. Double domes are better if you need more power and noise isolation. Some users even try both to find the best fit.

Check out our handy instructional videos on how to choose and change the dome size, as well as other topics.

Do I need a hearing aid battery tester?

One of our most popular hearing aid accessories, a hearing aid battery tester is a small, portable device designed to quickly check the remaining power in disposable hearing aid batteries.

The LED screen gives you an instant readout of whether the disposable battery is full, low or dead. 

Unlike regular batteries, zinc-air cells activate only when exposed to air, so they can lose power over time even if unused. The tester lets you avoid waste by checking if partially used batteries still have charge, and prevents surprises, like having your hearing aid cut out unexpectedly. A smart, inexpensive tool to keep in your kit.

Do I need to clean or replace the hearing aid tubes?

Hearing aid tubes are clear, flexible plastic tubes that connect the body of a behind-the-ear (BTE) hearing aid to the earmold or dome that sits in your ear canal. They carry the amplified sound from the hearing aid into your ear and play a crucial role in sound delivery and comfort.

Over time, hearing aid tubes can deteriorate and negatively affect sound quality and comfort. That’s why we recommend replacing them every 3 to 6 months, or sooner if you notice any issues like muffled sound, whistling (feedback) or visible wear.

Cleaning or replacing the tube is a simple process and can be done at home with the help of our instructional videos. You may find it helpful to use a hearing aid cleaning pin.

How do I keep moisture out of my hearing aids?

Drying tablets and a drying jar are simple but highly effective tools used to remove moisture from hearing aids and are especially valuable if you live in a humid climate, sweat frequently or wear your hearing aids for long hours each day.

What Is a Drying Jar?

A hearing aid drying jar is another one of the most popular hearing aid accessories. A drying jar is a small, sealable container designed to hold your hearing aids overnight when they’re not in use. Inside the jar, you place a drying tablet that absorbs moisture from the devices.

Using a drying jar helps prevent internal corrosion, blocked microphones or receivers, and intermittent performance problems due to moisture.

What Are Drying Tablets?

Hearing aid drying tablets are the moisture-absorbing component used inside a drying jar. They typically contain silica gel or other drying agents that pull moisture from the air and from within your hearing aids. 

Most hearing aid users benefit from using a drying jar and tablets, especially if:

  • You live in a humid environment or near water.
  • You experience sweat buildup behind your ears.
  • You’ve ever had hearing aids cut out unexpectedly or heard crackling or distortion. You want to extend the lifespan of your hearing aids.

Using a drying system is a simple, affordable way to protect your investment and keep your devices working at peak performance.
