Which Hearing Aid Dome Is Right for You?
The dome type is part of your hearing prescription — it directly affects sound quality, comfort, and feedback. Each hearing aid dome type serves a specific hearing loss profile.
Open Dome
Maximum airflow through large vents allows low-frequency sounds to pass naturally. The most comfortable hearing aid dome with minimal occlusion effect — ideal for first-time users and those with good low-frequency hearing. Reduces the "plugged" sensation while amplifying higher frequencies where hearing loss is present.
Closed Dome
A tighter seal with small vent holes — more amplification than an open dome but less occlusion than a power dome. The most commonly prescribed hearing aid dome for moderate hearing loss. Provides stronger bass response while still allowing some natural sound to pass through the vented design.
Power Dome (Double Dome)
Double-layer silicone membrane creates the tightest seal of all hearing aid domes — delivering maximum amplification and bass response for moderate-to-severe hearing loss. The power dome or double dome prevents feedback even at high gain settings. Expect a stronger occlusion effect; best for users who prioritize amplification over natural sound.
Tulip Dome
Overlapping flexible flanges (like tulip petals) conform to the ear canal shape — providing a secure fit in narrow, curved, or irregularly shaped canals where standard domes won't hold. A hybrid hearing aid silicone dome balancing the comfort of an open fit with the retention of a closed fit. Popular for Oticon and ReSound RIC receivers.
Domes for Every Major Hearing Aid Brand
Hearing aid domes are NOT universally cross-compatible. Each brand uses a proprietary attachment system. Our replacement domes are precision-molded to match each brand's receiver geometry exactly.

Hearing Aid Dome Size Guide
A proper dome fit should seal without discomfort. Too small causes whistling (feedback); too large causes soreness. Most adults fit in the Small–Large range.

What Makes a Quality Hearing Aid Dome
Not all silicone hearing aid domes are the same. Here's what to look for in a professional-grade replacement dome.
Medical-Grade Silicone
All our hearing aid domes are made from ISO 10993 biocompatible, latex-free silicone. Hypoallergenic formula minimizes skin irritation even with 12+ hours of daily wear — safe for sensitive skin and long-term use.
Precision-Molded Fit
Every silicone dome is injection-molded to exact tolerances — the attachment collar snaps securely onto the receiver and stays there. No wobble, no accidental detachment in the ear canal, and consistent acoustic performance across every batch.
Optimized Acoustics
The dome is an acoustic component, not just an earplug. Our vent geometries are designed to match each dome type's target frequency response — open domes for natural transparency, closed domes for balanced gain, power domes for maximum output without feedback.
Replace Every 4 Weeks
Hearing aid domes should be replaced monthly. Our bulk pack configurations ensure users always have fresh replacement ear tips on hand. Silicone naturally stiffens and yellows over time — regular replacement ensures consistent comfort and seal.
Color-Coded by Size
Each dome size has a distinct color for easy identification — no more guessing which size goes on which hearing aid. Standard color coding (transparent for open, grey for closed, etc.) or custom colors for your brand.
Retail-Ready Packaging
Bulk packs, clinic dispenser boxes, or consumer retail blister cards — we package hearing aid ear domes however your channel requires. Private-label packaging with your brand, logo, and barcode available for all dome types.
Common Questions About Hearing Aid Domes
How often should I replace my hearing aid domes?
Audiologists recommend replacing hearing aid domes every 4 weeks, or sooner if you notice yellowing, stiffening, tearing, or wax buildup. Silicone naturally degrades over time — a worn hearing aid dome can lose its seal, cause feedback, or even detach inside the ear canal. Monthly dome replacement is one of the simplest and most important hearing aid maintenance habits.
What's the difference between open, closed, and power domes?
Open domes have large vents for maximum airflow — best for mild hearing loss where natural low-frequency hearing is preserved. Closed domes have small vents for a tighter seal and stronger amplification — the standard for moderate loss. Power domes (double domes) have a double-layer membrane with no vents — maximum amplification and bass for moderate-to-severe loss, but the most occlusion effect. Your audiologist prescribes the dome type as part of your hearing aid fitting — changing dome types significantly changes the sound you hear.
Are hearing aid domes interchangeable between brands?
No. Hearing aid domes are NOT cross-compatible between brands. A Phonak SDS 4.0 dome won't fit an Oticon receiver, and a ReSound AllFit dome won't stay on a Signia receiver. Each manufacturer uses a proprietary attachment mechanism. Even within the same brand, dome systems can change between receiver generations — always check your hearing aid model's dome compatibility before ordering replacement domes.
How do I know which dome size I need?
Dome size is determined by your ear canal diameter. Sizes range from XS (5–6 mm) to XL (12+ mm). A properly sized hearing aid dome should slide in easily, seal comfortably without pressure, and stay in place when you move. Signs of a wrong size: whistling/feedback (too small), soreness within an hour (too large), or the dome falling out during normal activity. Your audiologist can measure your ear canal and recommend the right size.
Can I order domes with custom branding or packaging?
Yes. We offer full OEM hearing aid domes — private-label packaging with your logo, custom dome colors, and retail-ready blister cards or clinic dispenser boxes. Whether you're a hearing aid brand, clinic chain, or e-commerce seller, we manufacture custom silicone ear domes to your specifications. Minimum order quantity is flexible — contact us for a tailored quotation.
What material are your domes made from?
All our hearing aid domes are manufactured from medical-grade, ISO 10993 biocompatible silicone. The material is latex-free, hypoallergenic, and formulated for long-term skin contact — safe for 12–16 hours of daily wear. Our silicone maintains consistent flexibility across temperature ranges and resists the yellowing/stiffening that affects lower-grade materials over time.
