How Often Should You Change Hearing Aid Tubing, Domes, and Wax Traps?
By Dr. Jonathan Javid, Au.D.
Hearing aids are an investment in your health and quality of life — but like all technology, they need regular maintenance to perform their best. One of the most common questions my patients ask is: “How often should I change the tubing, domes, and wax traps on my hearing aids?”
Here’s a quick guide to replacement timelines:
- Tubing (BTE style): Every 4–6 months
- Domes (RIC and thin-tube styles): Every 1–3 months
- Wax traps: Every 2–4 weeks
Below, I’ll explain why each component matters, what signs mean it’s time to replace them, and tips for extending their lifespan. For a full overview of hearing aid parts and care, see Everything to Know About Hearing Aids.
When To Replace Hearing Aid Tubing
Hearing aid tubing connects the behind-the-ear hearing aid to the earmold. Its flexibility and clarity are essential for good sound delivery.
Signs it’s time to replace:
- Cracks, stiffness, or discoloration
- Condensation or wax build-up inside
- Reduced sound clarity
As a rule of thumb, tubing should be changed every 4–6 months. Neglecting tubing changes can cause feedback, poor sound quality, and discomfort.
How to Change Tubing
- Remove the old tubing from the earmold (keep it to measure the new one).
- Insert the tapered end of the new tubing and pull it through.
- Trim to match the old length.
- Attach securely to the hearing aid hook.
Many patients prefer having their audiologist do this during a follow-up appointment, but with the right tools, it can be done at home.
When To Replace Hearing Aid Domes
Hearing aid domes are soft silicone tips that cover the receiver and sit in your ear canal. They come in three main types:
- Open domes: Allow natural sound to pass through, reducing “plugged ear” feeling.
- Closed domes: Provide more amplification and reduce leakage.
- Power domes: Give maximum seal and amplification for severe loss.
When to change domes: Every 1–3 months, or sooner if they are:
- Stiff, cracked, or discolored
- Loose, causing feedback or poor fit
- Clogged with earwax or debris
Domes can be brushed clean between replacements, but eventually they lose flexibility. For step-by-step help, see our Complete Guide to Cleaning a Hearing Aid Dome or explore the best dome removal tools.
When To Change Hearing Aid Wax Traps
Wax traps (or wax guards) prevent earwax and moisture from reaching the delicate receiver. They’re one of the smallest but most important parts of your device.
When to replace: Every 2–4 weeks, depending on wax buildup. If your hearing aid suddenly sounds weak or silent — even with a fresh battery — check the wax trap first.
Most systems use a simple two-ended tool: one side removes the old filter, the other inserts a new one. For a visual guide, see our Illustrated Guide to All Hearing Aid Wax Traps.
Quick Comparison Table
| Component | Replacement Interval | Warning Signs | DIY or Audiologist? |
|---|---|---|---|
| Tubing (BTE) | Every 4–6 months | Stiff, cracked, condensation, weak sound | Often audiologist |
| Domes (RIC/Thin-tube) | Every 1–3 months | Loose fit, discoloration, clogged with wax | DIY |
| Wax Traps | Every 2–4 weeks | Weak or no sound despite fresh battery | DIY |
Final Thoughts
Keeping up with hearing aid maintenance may feel like a chore, but it’s what keeps your devices working reliably. Replacing tubing, domes, and wax traps on schedule improves comfort, sound quality, and prevents costly repairs.

Routine parts replacement is just one layer of hearing-aid care. Proper cleaning, troubleshooting buzzes or feedback, and understanding when to seek professional service all play a role in preserving sound quality and performance. Whether you’re dealing with moisture, debris, or general wear and tear, staying proactive saves you time, frustration, and money in the long run.
