Best Earplugs for Sleeping: Complete Buyer's Guide

Noise can ruin your sleep, whether it’s snoring, traffic, or loud neighbours. The right earplugs can block these disturbances and improve your rest. Here’s a quick overview of the main types of sleep earplugs:

• Foam Earplugs: Affordable, disposable, and block up to 33dB of noise. Custom earplugs vs. foam earplugs comparisons show foam is best for occasional use but can be uncomfortable for side sleepers.
• Silicone/Wax Earplugs: Reusable for months, reduce noise by 22–27dB, and sit over the ear canal for better comfort, especially for side sleepers.
• Custom-Moulded Earplugs: Made from medical-grade silicone, these offer long-term use, outstanding comfort (even for side sleepers), and reduce noise by 25–27dB. Prices range from $100–$200 AUD.

Custom options like ACS SleepSound earplugs are crafted to fit your ears, ensuring comfort and reliable noise reduction. They’re durable, lasting 3–5 years with proper care, and are ideal for those prioritising sleep quality.

Types of Sleep Earplugs

Sleep earplugs are available in three main categories, each catering to different preferences, budgets, and levels of comfort.

Foam Earplugs

Foam earplugs are the go-to option for affordability. These earplugs are made from a compressible foam material that expands to fit snugly in the ear canal, offering noise reduction levels of up to 33dB. This makes them effective for blocking out sounds like snoring or street noise. However, they aren't without drawbacks. Foam earplugs are typically designed for single-use or short-term wear, which can lead to discomfort if used daily. They may also push earwax deeper into the ear canal, which could cause irritation, especially for side sleepers.

If you're after something more reusable and comfortable, silicone and wax earplugs might be worth exploring.

Silicone and Wax Earplugs

Silicone and wax earplugs strike a balance between disposable foam options and more tailored solutions. These earplugs, made from hypoallergenic and moisture-resistant materials, reduce the "plugged" feeling often associated with foam. They offer noise reduction levels of 22–27dB. Unlike foam earplugs, silicone and wax varieties sit over the ear canal opening rather than being inserted deeply, which can help reduce itching or irritation. With proper cleaning using mild soap and warm water, these earplugs can last for several months, making them a more cost-effective choice in the long run. Wax earplugs are typically softer, while silicone putty versions are waterproof, making them versatile. Their lack of hard stems also makes them a comfortable option for side sleepers.

For those looking for the ultimate in comfort and durability, custom-moulded earplugs offer a premium alternative.

Custom-Moulded Earplugs

Custom-moulded earplugs are designed for those who prioritise comfort and long-term use. These earplugs are crafted from medical-grade silicone, with options like ACS Custom SleepSound earplugs available in firmer 40 Shore or softer 25 Shore versions. The softer variant, offering 23–25dB of noise reduction, is particularly suited for side sleepers or individuals with sensitive ears. Custom-moulded earplugs are made based on precise impressions of your ear canals, ensuring a perfect fit. They sit entirely within the canal, avoiding pressure points and staying securely in place during the night. While they cost between around A$200.00, they are built to last for years when cared for properly. The durable lacquer finish adds to their longevity.

What to Look for in Sleep Earplugs

Finding the right earplugs for sleep involves balancing key features like noise reduction, material comfort, and durability with your specific needs. The right choice can mean the difference between tossing and turning all night and waking up refreshed.

Noise Reduction Ratings (NRR and SNR)

Noise Reduction Ratings (NRR) measure how much sound earplugs can block, expressed in decibels (dB). For most bedrooms, an NRR of 20–25 dB is usually enough to handle typical background noises like traffic or household sounds. However, if you're dealing with louder interruptions - like a snoring partner or a nearby highway - earplugs with a higher rating, between 20–33 dB, are a better fit.

The type of noise matters too. Low-frequency sounds, such as snoring or humming HVAC systems (100–500 Hz), are best tackled with foam or mouldable beeswax earplugs that create a deep seal. On the other hand, mid-to-high frequency noises (500–4,000 Hz), like voices or higher-pitched sounds, are better blocked by silicone options. Regardless of the material, a snug seal is essential for maximum noise reduction.

Material choice also plays a big role in comfort, especially when wearing earplugs for extended periods.

Material and Comfort

Comfort is critical when it comes to sleep earplugs, particularly for side sleepers. The material determines how they feel in your ears and whether they’re suitable for nightly use. Medical-grade silicone is a popular choice because it’s hypoallergenic, resists moisture, and flexes to fit different ear shapes without causing irritation. Foam earplugs, while excellent for creating a tight seal, can sometimes feel intrusive or uncomfortable during prolonged wear.

If you sleep on your side, look for earplugs made from soft, contoured materials that sit flush with your ear. This design helps prevent pressure points when your head rests on a pillow. Studies have shown that earplugs can significantly reduce disruptions during the N3 (deep sleep) stage caused by environmental noise. So, prioritising comfort isn’t just about how they feel - it’s about ensuring consistent use for better rest.

Durability and Maintenance

The lifespan of earplugs varies greatly depending on the material. Foam earplugs are disposable and need frequent replacement to maintain hygiene and effectiveness. Silicone and beeswax options are more durable, often lasting for several months, while custom-moulded earplugs can last anywhere from 3–5 years with proper care.

To keep reusable earplugs in good condition, wash them with mild soap and warm water after each use. Allow them to air-dry thoroughly before storing them in a clean, dry container. Regularly inspect them for cracks, loss of elasticity, or a weaker seal - these are clear signs that it’s time to replace them. Proper maintenance not only extends their lifespan but also reduces the risk of ear infections during nightly use.

"Investing in quality earplugs isn't just about blocking sound; it's about taking care of your hearing and making your day a whole lot calmer." - Hamit Kanuni Kuralkan, Head of Research & Development, Otifleks

ACS Custom SleepSound: Custom Sleep Earplugs

If you're aiming for better sleep, SleepSound earplugs offer a personalised solution that combines comfort with dependable noise reduction. These earplugs outperform standard foam or silicone plugs in reducing noise. Initially created with shift workers in mind, these custom-moulded earplugs effectively minimise disturbances from snoring, traffic, and other nightly sounds.

Custom Fit for Maximum Comfort

What sets these earplugs apart is their tailored fit. Unlike generic plugs that rely on compression or expansion to seal, SleepSound earplugs are crafted from precise impressions of your ear canal. This ensures they stay in place all night without causing the pressure-related discomfort often associated with foam plugs.

"The key benefit of any custom-made item is its individuality and uniqueness to its user. Sleep Sound is no exception, and user acceptance is very high as each pair is individually crafted." – ACS Custom

The fit extends beyond the cartilage of your ear canal, eliminating the occlusion effect - that annoying booming sound of your own voice or breathing that poorly fitted earplugs can cause. For Australians, creating this custom fit involves visiting a qualified audiologist to take precise ear impressions. This bespoke design enhances the earplugs' noise-blocking capability while ensuring a snug, comfortable fit.

Noise Reduction Technology

Beyond comfort, SleepSound earplugs are built to provide consistent noise reduction. They reduce ambient noise by approximately 25–27 dB, making them perfect for blocking out snoring, traffic, and household sounds, while still allowing you to hear crucial alerts like an alarm clock. Thanks to their custom mould, the seal remains reliable night after night, unlike foam plugs, whose effectiveness can vary depending on how they're inserted.

Australian users have shared glowing feedback. Chris commented in February 2026: "Fits well and doesn't fall out. Can also sleep on my side without it being uncomfortable. Drowns out lots of sound and sleep has already improved". Similarly, David noted in March 2026: "Game changer! ...fitted for my ear and made of soft silicone they don't cause an ache when I wear them all night/day. And they don't fall out!".

Ergonomic and Durable Design

Made from 40 Shore medical-grade silicone and finished with a durable, flexible lacquer, these earplugs are designed to minimise skin irritation and discomfort, even during extended use. Their low-profile design ensures a flush fit, making them an excellent option for side sleepers.

In terms of durability, SleepSound earplugs typically last between 3 to 5 years with proper care, offering a long-term alternative to disposable options. Priced around $200.00 AUD, they deliver lasting performance. Maintenance is simple: use the included wax pick and comfort cream to keep the silicone in top condition and maintain the seal.

How to Choose and Get Fitted for ACS Custom Sleep Earplugs

Assessing Your Sleep Environment and Needs

Before ordering ACS SleepSound earplugs, take a moment to evaluate your sleep environment and specific needs. These earplugs reduce ambient noise by approximately 25–27 dB, making them an excellent choice for blocking out disturbances like snoring, traffic sounds, or daytime noise - especially helpful for shift workers. Made from 40 Shore medical-grade silicone, they’re designed to minimise irritation and discomfort, unlike traditional foam plugs that can sometimes cause earaches.

For those who care about aesthetics, you can opt for translucent colours instead of the standard clear finish.

The Ear Impression Process

Getting fitted for custom earplugs involves a straightforward ear impression appointment, lasting about 15–20 minutes for both ears. During this session, an audiologist will examine your ear using an otoscope, insert a protective foam block (called an otoblock) to shield your eardrum, and then fill your ear canal with soft silicone. This silicone sets quickly, capturing the precise shape of your ear canal. The deep impression is essential for creating an effective acoustic seal and ensuring optimal noise reduction.

Once your impressions are sent to ACS, the manufacturing process generally takes 3-4 weeks. Additionally, electronic scans of your impressions are stored for 2–3 years, so you can reorder without needing another fitting appointment during that time. Remember to remove any ear jewellery that might interfere with the moulding process.

After your custom earplugs are ready, keeping them in top condition is simple with proper care.

Care and Maintenance for Longevity

To maintain a secure fit and performance, update your ear impressions every 4 years. Use the care kit provided to protect the durable lacquer finish of your earplugs. They also come with a 12-month defect warranty and a 60-day fit warranty, giving you ample time to test them in your regular sleep environment. With minimal upkeep using the supplied care tools, your earplugs will continue to perform effectively for years to come.

Conclusion

This guide has walked through various sleep earplug options, showing how a custom solution can genuinely improve your sleep. High-quality sleep earplugs can make a big difference - whether you're dealing with a snoring partner, noisy neighbours, or the challenges of shift work. Custom-moulded earplugs, like the ACS SleepSound, are designed to block disruptive sounds while still letting you hear essential alerts, like your morning alarm. Unlike disposable foam plugs, which can cause discomfort or fall out during the night, custom earplugs are tailored for a snug, secure fit, making them ideal for side sleepers.

The personalised design eliminates common issues like pressure points and irritation that come with generic earplugs. This level of comfort and stability is crucial, especially considering the serious health risks linked to chronic sleep deprivation, such as cardiovascular problems and cognitive decline.

With proper maintenance, these earplugs remain clean and functional for years. Their durable, flexible lacquer finish ensures they stand the test of time. Priced around $200.00 AUD, custom-moulded earplugs are a smart investment in better sleep and long-term comfort.

Whether you're a shift worker needing daytime rest or just looking for peace and quiet in a noisy setting, custom earplugs offer the perfect mix of comfort, durability, and effective noise reduction for consistently restful nights.

FAQs

Will I still hear my alarm?

Yes, you should still be able to hear your alarm while using earplugs for sleep. Earplugs are made to lower distracting noises, not to eliminate all sounds entirely. This means alarms and other critical alerts can usually still be heard.

Are custom earplugs worth the cost?

Custom earplugs can definitely be worth the investment. Their tailored fit ensures unmatched comfort, making them ideal for extended wear. Plus, they are built to last - often for 4–5 years - providing durability that standard earplugs simply can't match. While the initial price, around $200 AUD, might seem steep, their long-term use and effectiveness can actually save money over time compared to frequently replacing disposable or less durable options.

How do I stop earplugs hurting my ears?

To avoid discomfort from earplugs, it's essential to pick the right type and ensure they fit properly. Custom-moulded earplugs, designed specifically for your ear shape, provide greater comfort and minimise irritation. For standard earplugs, look for options made from soft, skin-friendly materials such as silicone or foam. Always insert them gently without applying too much pressure, and make sure to replace disposable earplugs regularly to keep them hygienic and comfortable.
