Hearing aid domes are small, soft tips that sit on the end of your hearing aid’s speaker. They direct sound into your ear canal and help keep your hearing aids in place. Though often overlooked, domes play a major role in how well your hearing aids perform.
If you want better sound quality, greater comfort, and fewer issues with feedback, choosing the best hearing aid domes is essential. The right dome can transform your listening experience and help you hear more naturally.
Let’s explore everything you need to know about finding the best hearing aid domes for your ears and hearing needs.
What Do Hearing Aid Domes Do?
Domes help secure the hearing aid in your ear canal and direct sound efficiently. They create a seal that controls how much amplified and natural sound you hear. The seal’s tightness also impacts how much sound escapes and potentially re-enters the hearing aid’s microphone.
A poor seal can cause sound to leak, creating that annoying whistling feedback. A good seal improves clarity and keeps sound from looping back.
Domes also prevent dirt and wax from entering the hearing aid’s speaker. Clean, properly fitted domes help maintain sound quality and device longevity.

Why Fit and Style Matter
Your ear canal shape, hearing loss type, and comfort preferences all influence which dome works best. A dome that’s too tight may cause discomfort. A dome that’s too loose may fall out or cause feedback.
Domes come in several shapes and sizes, and each one works best for different users. The right dome reduces the “plugged up” sensation and delivers clearer, more natural sound.
Working with a hearing care provider ensures you get the correct style, size, and fit.

Open, Closed, Tulip, and Power Domes: What’s the Difference?
Hearing aid domes fall into four major categories. Each style has specific advantages depending on your hearing profile.
1. Open Domes – A Breathable Listening Experience
Open domes contain multiple holes that allow low-frequency sounds to pass through naturally. These domes reduce the occlusion effect, which is the sensation of hearing your own voice echo in your head.
Best For:
People with mild or high-frequency hearing loss.
Benefits:
- Natural sound and better awareness of surroundings.
- More ventilation in the ear canal.
- Comfortable for all-day wear.
Drawbacks:
- Less effective for moderate to severe hearing loss.
- More likely to cause feedback due to sound leakage.
- Limited low-frequency amplification.
Real-Ear Acoustic Results:
Research shows open domes only reach full acoustic gain at 2 kHz, limiting low-frequency support.
Pro Tip:
Open domes suit people who still benefit from ambient sounds and don’t need strong amplification.
2. Closed Domes – Clearer Speech, Less Noise
Closed domes block external sounds and direct more amplified sound into your ear. They offer a more solid barrier and fewer or no vents compared to open domes.
Best For:
People with mild to moderate hearing loss who need more amplification.
Benefits:
- Improved speech clarity in noisy places.
- Better low-frequency amplification.
- Reduced feedback.
Drawbacks:
- Can create a “stuffed up” or occluded feeling.
- May distort your voice perception.
- Less situational awareness.
Pro Tip:
If open domes cause feedback or sound too airy, closed domes may work better.
3. Tulip (or Plus) Domes – The Happy Medium
Tulip domes feature two overlapping silicone flaps that provide a semi-closed seal. They strike a balance between open and closed domes, offering moderate amplification with limited feedback.
Best For:
People who want more sound control without a fully closed-off feel.
Benefits:
- Less feedback than open domes.
- More natural sound than power domes.
- Comfortable in larger ear canals.
Drawbacks:
- May not seal as well in narrow or angled ear canals.
- Not as strong as power domes for severe loss.
Frequency Gain Insights:
Tulip domes perform well in the 1-2 kHz range but offer less low-frequency boost than power domes.
4. Power Domes – Maximum Amplification and Feedback Control
Power domes, also called double domes, create a tight seal for the highest level of amplification. They’re the most occlusive dome style and ideal for those with severe hearing loss.
Best For:
Moderate to severe hearing loss requiring powerful sound gain.
Benefits:
- Reduces feedback dramatically.
- Captures soft sounds clearly.
- Strong low-frequency amplification.
Drawbacks:
- High occlusion effect.
- Can feel more “plugged up.”
- May be less comfortable for all-day wear.
Research-Based Findings:
Power domes provide significantly higher gain at 250 Hz and 500 Hz compared to tulip domes.
Dome Sizes: Why One Size Doesn’t Fit All
Every ear canal is different. Even your left and right ear may need different dome sizes.
Signs Your Dome Is Too Big:
- Dome falls out during wear.
- Loose fit causes sound to leak.
- Feedback or weak sound.
Signs Your Dome Is Too Small:
- Persistent pressure or soreness.
- Dome feels stuck after removal.
- Difficult to insert fully.
Pro Tip:
Start with a recommended size, then adjust based on comfort and performance.

Hearing Aid Feedback and How Domes Help
Feedback happens when sound escapes and re-enters the hearing aid microphone. It often results in a high-pitched whistling sound.
How Domes Reduce Feedback:
- Closed, tulip, and power domes seal the canal, limiting sound escape.
- Open domes may increase feedback in noisy settings.
- A proper fit ensures the dome stays in place and blocks leakage.
To test for feedback, cup your hand around your ear with the device on. If you hear whistling, you likely need a tighter-fitting dome.
How to Clean and Replace Your Domes
Proper dome care keeps your hearing aids performing well and your ears healthy.
Daily Cleaning:
- Remove the dome.
- Wipe gently with a soft, dry cloth.
- Avoid alcohol or sharp tools.
Weekly Cleaning:
- Use an approved cleaning solution and tools.
- Clean around the dome and speaker.
- Let parts dry completely before reassembling.
Dome Replacement:
- Replace domes every 6–8 weeks.
- Replace sooner if cracked, torn, or discolored.
- Always use manufacturer-approved replacements.
How to Change Your Hearing Aid Domes
Changing your domes is simple and quick.
- Grip the dome at the base and pull gently to remove.
- Align the new dome with the receiver tip.
- Push until it snaps securely into place.
Check that the dome is snug and won’t come off in your ear.
Final Checklist: Choosing the Best Hearing Aid Domes
Still unsure which dome is right? Use this checklist to guide your decision:
- Do you have mild hearing loss? → Try open domes.
- Need more clarity in noise? → Consider closed domes.
- Want a middle ground? → Tulip domes might be best.
- Struggle with feedback or need strong amplification? → Power domes are ideal.
- Experiencing discomfort or whistling? → Adjust the size or style.
- Need a better fit in one ear? → Use different domes in each ear if needed.
