How to replace BTE hearing aid tubes

A hearing aid tube is a key part of a behind-the-Ear (BTE) hearing aid. It connects the main body of the device — which contains the receiver, microphone, and amplifier — to the ear canal. Through this small, flexible tube, sound is delivered directly into the ear. The hearing aid itself sits discreetly behind the ear, while the tube ensures clear sound transmission.

BTE hearing aids are known for offering the most powerful amplification among all hearing aid styles. However, they rely on properly maintained tubes to function effectively. Regular care and timely hearing aid tube replacement are essential to maintain sound quality and device performance.

Hearing aid tubes come in different types and sizes to suit various hearing needs and hearing aid models. They may connect to an earmold or a hearing aid dome, depending on the wearer’s level of hearing loss and the design of the device.

Hearing aid tubes are typically clear and flexible, providing comfort and a discreet appearance. They differ in both diameter and length, and sizing may vary slightly between manufacturers — so it’s important to use tubes made specifically for your hearing aids.

Here’s an overview of the main tube sizes and their ideal uses:

• Thick Tube: Best for moderately severe to profound hearing loss. The wider diameter allows more amplified sound to reach the ear canal.
• Thin Tube: Suitable for mild to moderate hearing loss. These are lighter and less noticeable.
• Short Tube: Commonly used for children and individuals with smaller ears.
• Medium Tube: Designed for average-sized adults.
• Long Tube: Ideal for taller individuals or those with larger ears.

Maintaining and replacing your hearing aid tubes as needed helps ensure optimal comfort, clarity, and performance from your hearing aids.

Before starting, prepare a clean workspace and gather the following items:

• New tubing: Make sure it’s the correct size and thickness for your BTE hearing aid model.
• Small scissors or a tubing cutter
• Pliers (optional, for removing stiff tubing)
• A bowl of warm water (optional, to soften the old tubing if it’s hard to remove)

Tip: Wash your hands thoroughly before you begin to prevent transferring dirt or wax to the new tube. Before removing the old tubing, take note of how it’s positioned — particularly the angle where it connects to the earmold. This will help ensure that your new tubing sits properly when fitted.

After replacing the tubing, take a few moments to clean and check your hearing aid:

• Wipe the earmold and tubing with a soft, dry cloth to remove any residue or moisture. 
• Reattach the earmold to the hearing aid and listen to make sure the sound is clear and undistorted. 
• If the sound seems weak or muffled, inspect the tubing carefully to ensure it isn’t twisted, pinched, or blocked by wax or moisture.

Performing these quick checks helps confirm that the new tube is fitted correctly and that your hearing aid is working as expected.

For best performance, replace the tubing on your Behind-the-Ear (BTE) hearing aid every three to six months, or sooner if you notice any of the following:

• The tubing has become yellowed, brittle, or cracked 
• Moisture or condensation appears inside the tube 
• The sound has become quiet, distorted, or inconsistent 
• The earmold feels loose or doesn’t sit comfortably in your ear 

Regular tubing replacement helps maintain sound quality, comfort, and hygiene, while also extending the overall lifespan of your hearing aid.

What tools or supplies will you need? You’ll need:

• New tubing that matches your hearing aid model 
• Small scissors or a tubing cutter 
• Pliers or tweezers (optional, for removing stiff tubing) 
• (Optional) A bowl of warm, soapy water to soften the old tubing before removal
