The trick to comfortable, effective earplugs at night comes down to matching the technique to the type of earplug you’re using. Foam, silicone, and wax earplugs each go in differently, and getting it wrong is the main reason people wake up with sore ears or wonder why they can still hear everything. Here’s how to get a proper seal with each type and keep them comfortable all night.
How to Insert Foam Earplugs
Foam earplugs are the most common and typically offer the highest noise reduction, but they only work if you give them time to expand inside your ear canal. The CDC recommends a three-step process.
First, roll the earplug between your fingers into a small, thin cylinder. You want it compressed as tightly as possible. Second, reach over your head with the opposite hand and pull the top of your ear up and back. This straightens your ear canal, which naturally has a slight curve, and makes insertion much easier. Third, slide the compressed earplug into your ear canal and hold it in place with your fingertip while counting to 20 or 30. This waiting period is the step most people skip, and it’s the most important one. The foam needs that time to expand and fill the shape of your canal. If you let go too early, the plug will partially push itself back out and you’ll get a loose, ineffective fit.
A properly inserted foam earplug should sit mostly inside the ear canal. If you can grab it easily with your fingertips, it’s not deep enough. Looking in a mirror, a well-fitted plug should barely be visible from the front.
How to Fit Moldable Silicone or Wax Earplugs
Moldable earplugs work completely differently from foam. They don’t go inside your ear canal at all. Instead, they create a seal over the opening.
For silicone putty earplugs, start by rolling the plug into a smooth ball with clean, dry fingers. Press the ball gently over your ear canal opening and flatten it to create a full seal. Then smooth the edges so nothing sticks out or pinches against your skin. The goal is a disc-like shape that covers the canal entrance without any gaps around the edges.
Wax earplugs follow a similar approach, but the material is stiffer at room temperature. Warm the wax between your fingers until it becomes soft and pliable, then roll it into a ball and press it over the canal opening. Don’t try to push either type into the canal. They’re designed to work as a barrier on the surface, which is why many people find them more comfortable for sleeping than foam.
Getting Comfortable as a Side Sleeper
Side sleepers have the hardest time with earplugs because the pillow pushes against whatever is in or around your ear. Foam earplugs that protrude from the canal create a pressure point that can wake you up or leave your ears aching by morning.
The most comfortable options for side sleeping are earplugs that sit flush with the ear opening or don’t protrude at all. Moldable silicone plugs are a natural fit here since they sit flat over the canal entrance rather than sticking out. Among pre-shaped earplugs, designs made from flexible silicone that mold to the inner ear and have no external protrusion tend to perform best. Some products also include a pressure-equalization chamber that reduces the “plugged up” feeling that bothers some sleepers. If you’re using foam, make sure the plug is inserted deep enough that it doesn’t extend past the ear canal, which both improves the seal and reduces contact with your pillow.
How Much Noise Earplugs Actually Block
Every earplug package lists a Noise Reduction Rating, or NRR, measured in decibels. That number is measured under ideal lab conditions, so real-world protection is lower. The standard formula: subtract 7 from the NRR, and that’s roughly how many decibels the earplug reduces in practice. A plug rated at NRR 33 gives you about 26 decibels of actual reduction. A plug rated at NRR 22 gives you about 15.
For sleeping, you generally don’t need maximum noise reduction. A snoring partner typically produces 40 to 60 decibels, and street traffic at night runs 50 to 70. An earplug with an NRR in the low-to-mid 20s is usually enough to bring those sounds below the threshold that disrupts sleep, while still letting you hear a smoke alarm or a child calling out. Higher NRR foam plugs are available, but they can feel more intrusive in the ear and may be overkill for bedroom noise levels.
When to Replace Your Earplugs
Foam earplugs are single-use. Washing them with water causes the foam to expand permanently and lose the density it needs to block sound. Discard foam plugs after one night and start fresh. Trying to reuse them also introduces bacteria back into the ear canal, which raises infection risk.
Moldable silicone and wax plugs vary by brand, but most are designed for a few uses before the material picks up too much oil and debris to form a clean seal. Check the packaging for the manufacturer’s recommendation. Reusable silicone earplugs with a fixed shape can be washed with mild soap and warm water between uses and typically last several months before the material degrades.
Protecting Your Ear Health
Wearing earplugs every night can interfere with your ears’ natural self-cleaning process. Your ear canals slowly push wax outward on their own, and anything sitting in the canal blocks that exit route. Over time, this can lead to earwax impaction, which shows up as muffled hearing, a feeling of fullness, itching, or occasionally dizziness. Some people are more prone to wax buildup than others based on their canal shape and how much wax they naturally produce.
Nightly earplug use can also cause otitis externa, an inflammation of the ear canal that causes pain and tenderness. The combination of trapped moisture, warmth, and a foreign object creates an environment where bacteria can grow. To reduce your risk, always insert earplugs with clean hands, let your ears air out during the day, and never force a plug deeper than it naturally wants to sit. If you notice increasing fullness or hearing changes, hydrogen peroxide drops or professional wax removal can clear things up before symptoms become more serious.
