BTE hearing aids maintenance & care

Simple routine, few issues

Without proper care, hearing aids can be affected by earwax buildup, moisture, or everyday wear and tear, factors that may reduce sound quality or even lead to costly repairs.

The good news is that behind-the-ear (BTE) hearing aids are relatively easy to maintain if you follow a consistent routine. By setting aside just a few minutes each dayweek, and month to clean and inspect your devices, you can keep them performing their best and extend their lifespan.

BTE hearing aids: parts and features

Behind-the-ear (BTE) hearing aids are one of the most common and versatile solutions for people with hearing loss. As the name suggests, the main body of the device rests comfortably behind the ear, while a thin tube or a custom ear mold then directs amplified sound into the ear canal. BTEs are made up of several key parts:

  • Microphone: picks up sound from the environment
  • Amplifier and processor: adjusts and strengthens incoming sound
  • Speaker or receiver: delivers the sound into the ear canal
  • Battery compartment or rechargeable power cell: powers the device

BTE models are especially popular because they deliver strong amplification suitable for mild to profound hearing loss, while also offering modern features that improve everyday listening. Many BTEs offer Bluetooth connectivity for streaming calls, music, and TV audio directly to the ears, rechargeable batteries for convenience, and directional microphones that help users focus on conversations in noisy places. Some models are also compatible with telecoils, apps, or remote controls, giving wearers more flexibility and control over their hearing experience.

Before diving into maintenance, it’s helpful to know which parts of your BTE hearing aid need regular attention. Two components that often require replacement over time are filters and tubing. Keeping these parts in good condition ensures your hearing aid continues to perform at its best.

Filters

The filters in BTE hearing aids prevent earwax and debris from entering the device and affecting its performance. Here’s how to replace them:

  • Guide: Follow the manufacturer’s instructions to remove the old filter and insert the new one.
  • Frequency: Replace the filter once a month or as recommended by your hearing care professional.
  • Tools needed: Make sure you have the proper tools and replacement filters ready before you start.

Tubing

The tubing connects the hearing aid to the earmold and can wear out over time. Here’s how to change it:

  • Guide: Remove the old tube and attach the new one, making sure it is firmly secured.
  • Frequency: Replace it at least twice a year, or sooner if needed.
  • Tools needed: Use the appropriate tools to ensure a proper and secure replacement.

If you’d rather not do it yourself – or have questions on the process—take advantage of the unlimited care that comes with most Miracle-Ear purchases*.  You can schedule appointments anytime for filter or tubing replacements or other maintenance needs.

Professional hearing aid cleaning and check-ups

Even with diligent at-home care, professional maintenance is essential for keeping BTE hearing aids in optimal condition. With Miracle-Ear’s unlimited care, you can schedule appointments whenever you need expert support—whether it’s for a routine cleaning, inspection, or small adjustment.

During a professional cleaning, your hearing care professional can:

  • Safely remove stubborn earwax or debris that may have built up in the tubing, microphone, or receiver.
  • Inspect and replace tubing or other components, as needed.
  • Perform performance tests to make sure your hearing aids are delivering the right amplification for your hearing profile.

Many providers recommend scheduling a check-up every six months, although this interval can vary depending on factors such as usage, lifestyle, earwax production, and exposure to moisture and humidity. These appointments also provide an opportunity to ask questions, discuss changes in your hearing, and explore updates or adjustments to your devices.

Professional care ensures your hearing aids continue to perform optimally, extend their lifespan, and prevent minor issues from developing into costly repairs. With unlimited care, getting this professional support is easy, convenient, and flexible.

Ask our professionals

If questions come up when you're cleaning your hearing aids, know that you aren't on your own. If you have specific questions about how to clean hearing aids or ongoing maintenance, ask your hearing care professional. He or she will be able to ensure you’re getting the most out of the lifetime care and service* that comes with every Miracle-Ear hearing aid purchase.

Storage and handling tips for BTE hearing aids

Proper storage and handling are just as important as cleaning when it comes to hearing aid maintenance. Always remove your BTE hearing aids before showering, swimming, or using a sauna, as water can permanently damage the delicate electronics. The same goes for hairspray, perfumes, or lotions—apply these products first, then insert and your devices.

When not in use:

  • Store your hearing aids in a protective case to avoid accidental drops or scratches.
  • If you use disposable batteries, keep the battery door open when storing the aids overnight to reduce moisture buildup.
  • For rechargeable models, place them in their charging station as recommended by the manufacturer.
  • Avoid heat — never leave hearing aids in a hot car, near a radiator, or in direct sunlight for extended periods.
  • If you’re traveling, consider carrying a portable drying kit to protect your devices from varying climates.

By handling your hearing aids with care and storing them properly, you prevent unnecessary wear and ensure consistent sound quality. These small habits may seem simple, but they make a big difference in preserving the performance and longevity of your devices.

Troubleshooting BTE hearing aids: When to call a professional

Even with regular maintenance, issues can arise. Common signs that something is wrong include: muffled or distorted sound, sudden feedback or whistling, or unexpected shutdowns.

Start with basic troubleshooting at home:

  • Check that the battery is charged or working properly.
  • Inspect the tubing and filter for blockages from wax or moisture.
  • Make sure the tubing is flexible and securely attached, replacing it if necessary.
  • Swapping the wax guard for a new one if the sound is still weak.

These quick fixes often solve minor issues at home. If the problem persists, consult your hearing care professional. They can identify whether the issue is related to a blocked component, worn-out tubing, or a deeper electronic fault. With Miracle-Ear’s unlimited care, you can get professional help anytime for inspections, repairs, or adjustments, giving you peace of mind and reliable support for your hearing.

Protect your hearing health with proper BTE care

Maintaining your BTE hearing aids doesn’t have to feel overwhelming. By following a simple routine— daily cleaning, weekly inspections, monthly filter and tubing replacements, and professional check-ups— you can protect your investment and ensure your devices always deliver clear, crisp sound.

These habits prevent common issues like muffled sound or feedback and extend the overall life of your hearing aids. Think of it as routine care that keeps you connected to the world around you. If you ever feel unsure about a maintenance step, don’t hesitate to ask your hearing care professional for guidance—they can provide hands-on demonstrations and personalized advice.
