Do Ear Plugs Help When Flying? | Filters vs. Foam

Cabin pressure shifts on ascent and descent are what cause that plugged, popping, sometimes painful feeling in your ears. Wearing earplugs helps in two distinct ways: ordinary foam plugs reduce the roar of the engines, while pressure-regulating earplugs with a special filter are designed to slow how fast pressure changes reach your ear canal, giving your middle ear more time to adjust. The type you choose matters more than most people expect.

What Earplugs Actually Do During a Flight

Earplugs help with two separate problems, and the fix for each is different. For noise, any well-fitting foam plug works well. For the pressure-related discomfort, popping, and fullness you feel on takeoff and landing, a pressure-regulating filtered plug is the tool designed for the job.

Filtered airplane earplugs contain a small valve or filter that controls airflow. EarPlanes, for example, uses a patented filter it says gently balances cabin pressure, while Mack’s Flightguard plugs use an AERO FILTER to regulate ear pressure. The idea is that the filter slows the pressure change enough that your Eustachian tube keeps up, rather than getting overwhelmed all at once.

The takeaway: earplugs genuinely help many people, but they are not a guaranteed fix for every ear.

Filtered Earplugs vs. Regular Foam: Know the Difference

The key distinction is noise-only versus pressure-regulating. Standard foam earplugs are excellent at blocking sound but do nothing to manage pressure changes. If your main complaint is engine noise and you want to sleep, foam is fine. If takeoff and landing cause you ear pain, you want a filtered plug built for flight.

Popular options in the filtered category include EarPlanes, Mack’s Flightguard Airplane Pressure Relief Ear Plugs, and Alpine’s flight earplugs. All work on the same principle: regulate the air pressure reaching your eardrum so it can adjust more gradually. The practical trade-off is that filtered plugs may block slightly less noise than high-NRR foam, but for most flyers the pressure relief is worth it.

How to Use Airplane Earplugs for the Best Result

Timing is everything. EarPlanes says to insert the plugs prior to takeoff and landing and keep them in until cabin pressure neutralizes. Mack’s guidance is similar: insert before takeoff, keep them in through the flight, and remove them after landing once the cabin door has opened. The brand also notes they should always be in place one hour before landing.

• Insert before takeoff, not when pain starts. Once your ears hurt, it is often too late for the filter to help.
• Keep them in during descent—that is when pressure changes hit hardest.
• Swallow, yawn, and hydrate too. Amplifon’s guidance pairs earplugs with these active equalization moves rather than treating plugs as a replacement for them.

Earplugs are generally safe for air travel when they fit comfortably and do not irritate your ear canal. They are relevant for adults and children alike, per Amplifon’s travel guidance. One travel source notes there is no scientific proof that earplugs eliminate in-flight ear pain; the honest framing is that filtered plugs are designed to help and are widely recommended, but the degree of benefit varies from person to person.
