Dealing with a Popping Hearing Aid Retention String: Tips and Solutions

Hearing aid retention strings—also called sport locks or stabilizers—are small, flexible wires designed to keep receiver-in-canal (RIC) hearing aids securely in place. When fitted correctly, they gently press against the wall of your ear canal, providing stability during movement and reducing the chance of the aid slipping out.

But for many users, these little wires can cause a surprising problem: they pop out of the ear canal or irritate the skin. This not only feels uncomfortable but can also affect how well your hearing aids sit in your ears, potentially reducing sound quality and creating unnecessary frustration.

Why Do Retention Strings Pop Out?

There are several reasons why a retention string may not stay put:

• Ear canal shape – Everyone’s ears are different. A retention string that fits one person perfectly might poke or pop out in another.
• Wire length and stiffness – If the stabilizer wire is too long, too straight, or too stiff, it may not sit comfortably against your ear canal wall.
• Incorrect insertion – Sometimes the issue isn’t the wire itself but the way it was placed in the ear. A slightly different angle of insertion can make a big difference.
• Normal wear and tear – Over time, retention wires can lose flexibility or become deformed, leading to fit problems.

Signs of a Poorly Fitting Retention String

You may notice problems like:

• A popping or tickling sensation inside your ear
• The wire visibly sticking out after insertion
• Discomfort or irritation, especially if the wire rubs against sensitive skin
• Hearing aids feeling looser than normal, particularly during chewing or talking

If these sound familiar, don’t worry—there are several easy adjustments you can try at home before considering a replacement.

Quick Fixes You Can Try

Here are the most common solutions audiologists recommend:

1. Curl the Wire

A simple bend or curl can help the wire hug your ear canal more naturally. Use your fingers to gently curve it into shape—no tools required. Start small and test the fit before making bigger adjustments.

2. Bend It Upward

If the wire presses against a sensitive spot, bending it slightly upward can redirect it and reduce irritation.

3. Trim Excess Length

If the wire is too long, you can carefully trim it with sharp scissors. Always cut in very small amounts and test after each adjustment. Cutting too much may ruin the stabilizer, so proceed cautiously.

Pro Tip: If you’re nervous about trimming or curling the wire yourself, bring your hearing aids to your audiologist. They can make the adjustment safely and suggest alternative retention methods.

When to Replace or Remove the Retention String

If adjusting or trimming doesn’t solve the problem, it may be time to replace or even remove the retention string entirely:

• Replace: Retention wires are inexpensive and easy to swap out. If your current one is worn or bent, ask your audiologist for a replacement.
• Remove: Some users simply do better without them. If your hearing aids sit snugly without the wire, it’s safe to leave them off.

Alternative Stability Options

If you find retention strings uncomfortable, consider alternative ways to keep your hearing aids secure:

• Different dome styles: Switching from an open dome to a power dome or double dome can sometimes improve stability. Learn more in our article on hearing aid domes.
• Custom earmolds: For a long-term solution, custom earmolds provide a precise fit and reduce movement.
• Retention accessories: Clips, ear grips, and sports locks can help secure devices during activity.

When to See an Audiologist

While small adjustments at home often help, there are times when professional help is best. Contact your audiologist if:

• The wire causes ongoing irritation or soreness
• Your hearing aids feel loose despite adjustments
• You’re unsure about trimming or removing the wire yourself

An audiologist can not only adjust or replace the wire but also check for ear canal issues or recommend alternative fittings like custom molds.

Preventive Care Tips

Most retention string issues arise from wear and tear or improper fit. A few preventive measures can help:

• Regular cleaning: Keep retention wires free of wax buildup. Learn how to clean microphones and hearing aid components safely.
• Check other parts: While adjusting your retention string, it’s a good time to inspect wax traps and tubing or domes for blockages or wear.
• Store properly: Use a hearing aid case or dryer to keep wires from bending when not in use.

Final Thoughts

Retention strings are designed to improve comfort and stability—but if yours keeps popping out, you don’t have to live with the annoyance. By curling, trimming, replacing, or switching to alternatives like custom earmolds, you can find the solution that works best for your ears.
