How to replace BTE hearing aid tubes

The tubing on a Behind-the-Ear (BTE) hearing aid connects the earmold to the hearing aid itself. Over time, it can harden, become discolored, or trap moisture and earwax, which can reduce sound quality and comfort. Replacing the tubing is a simple, routine maintenance task that can help your hearing aids perform like new again.

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.

Follow these steps carefully to replace the tubing on your Behind-the-Ear (BTE) hearing aids. Proper replacement helps maintain sound quality, comfort, and fit.

1. Detach the earmold
   Hold the hearing aid firmly by the hook and gently pull the earmold away. Avoid twisting, as this can damage both the tubing and the hearing aid's connector.
2. Remove the old tubing
   Pull the old tubing out of the earmold. If it’s stiff or difficult to remove, soak the earmold (with the tubing still attached) in warm, soapy water for a few minutes to soften it. Then, carefully pull it out using your fingers or a pair of pliers.
   In some cases, the tubing is cemented into the mold and may break—if this happens, remove any remaining pieces and make sure all of the old tubing is fully cleared before inserting the new tubing. If you have difficulty replacing the tubing at any point, return to your HCP for assistance.
3. Tip: Keep the old piece of tubing to use as a guide when cutting your new one to the correct length.
4. Thread the new tubing through the earmold
   Take the tapered end of the new tubing and insert it into the top hole of the earmold — this is the sound canal opening. Gently pull the tubing through until it comes out of the opposite side. Continue pulling until the bend of the tubing sits neatly and flushes with the back of the earmold, forming a smooth 90-degree angle. This position ensures a secure fit and clear sound transmission.
5. Trim the excess tubing
   Using small pair of scissors, carefully trim the tubing so it is level with the back of the earmold. The tubing should sit snugly without sticking out or feeling loose.
6. Measure and cut to length
   Place the old tubing alongside the new one and cut the new piece to the same length. Trim the end that will attach to the hearing aid hook at a slight angle or point — this makes it easier to slide on securely.
7. Connect the new tubing
   Push the newly cut end of the tubing firmly onto the hearing aid’s hook. It should feel tight and secure, with no gaps or wobbles. If the connection feels loose, push it slightly further onto the hook or re-trim the end to make a better fit. Finally, insert the earmold into your ear to check the fit. The tubing should follow a smooth, natural curve from the hearing aid to your ear without pulling, twisting, or kinking.

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.

Common signs include:

• Sound that seems muffled or weaker than usual 
• Tubing that’s stiff, discolored, or cracked 
• Condensation or moisture inside the tubing 
• The earmold doesn’t fit as securely as before

Yes. Replacing BTE tubing is a basic maintenance task that most users can do at home by following a step-by-step guide. However, if the tubing is difficult to remove or attach, or if you’re unsure about the correct length, it’s a good idea to ask your hearing care professional for help.

The tubing should fit snugly onto the hearing aid’s hook and sit flush with the back of the earmold. It shouldn’t feel loose or pull tightly when the earmold is in your ear. If it’s too short, it may cause discomfort; if it’s too long, the tubing can kink or affect sound quality.

No. BTE hearing aids require tubing that matches the specific diameter and length recommended by your hearing care provider or hearing aid manufacturer.
Using the wrong tubing can affect fit, sound quality, and durability.

Yes. Before inserting the new tubing, wash the earmold in warm, soapy water and let it dry completely. This prevents moisture or wax from getting into the new tubing and helps maintain hygiene.
