The Best Earplugs for Flying

Manufacturer-published attenuation figures, compiled 6 October 2026. NRR and SNR are different measurement standards and are not interchangeable — see below. We have not tested any of these.

The four, as published

The trap: NRR 33 is not better than SNR 25 by eight decibels

This is the single most useful thing on the page, and almost nobody says it. The two numbers above come from two different measurement systems. NRR is the US rating, computed under EPA labeling rules. SNR is the European single-number rating. They are derived from laboratory attenuation data in different ways, and a product’s NRR and SNR figures are not the same number.

So the honest reading of the table is not “33 beats 25 by 8 dB”. It is: the foam plug is rated on the scale that US products use, the filtered plugs are rated on the scale European products use, and you can only safely rank within a column. Within NRR, 33 is the ceiling — no foam plug sold in the US publishes higher. Within SNR, 25 beats 24 beats 17.

What a filter actually does, and why it matters at 30,000 feet

Foam is indiscriminate. It attenuates the engine drone, the cabin crew, the safety announcement and the gate change over the PA with equal efficiency. On an overnight flight that is exactly what you want. On a connecting itinerary where the gate may move, it is a real cost.

Alpine publishes that SleepSoft carries an “AlpineAcousticFilter” and states the design intent plainly: doorbells, alarm clocks and alarms remain audible while unwanted noise is reduced. Loop publishes a comparable position for the Quiet 2 at 24 dB SNR. Neither maker publishes a frequency response curve, so the shape of that selectivity is not something we can show you — only that both makers claim it and foam makers do not.

Cost per use, which reverses the ranking

This is a site about durability per dollar, so the arithmetic matters. Mack’s publishes ten pairs in the box. Alpine publishes that SleepSoft and FlyFit are reusable up to 100 times.

At $0.17 a use the reusable plugs are cheap, provided you keep them for a hundred flights — which, at the two to six flights a year this site is written for, is a 20 year assumption. That is the honest caveat: the per-use figure is real arithmetic over a horizon almost nobody reaches.

The one that is not about noise at all

FlyFit publishes a different mechanism entirely. Alpine states that its filter regulates cabin pressure “like a valve” so the ear can equalise during climb and descent, and markets it to people who get ear pain when flying rather than people who cannot sleep. Its 17 dB SNR is the lowest figure here precisely because heavy attenuation is not the goal.

If you have ever landed with one ear blocked for a day, that is the product. If you have not, it is the wrong purchase and the skip note above says so.

Earplugs or noise-cancelling headphones?

Both, for different noise. Active cancellation is very good at the steady low-frequency engine drone and poor at the irregular mid-frequency sound — a baby, a conversation, a trolley — that actually wakes people. Passive attenuation does the opposite. Our sleep kit page runs the full argument, and the headphones page covers the active side.

The weight argument is not close. The lightest over-ear headphone in our ledger publishes 251 g. Alpine publishes 30 g for the SleepSoft on its own page and 17 g on the retail listing — the two disagree, and at this scale it does not matter. On Hawaiian’s published 25 lb carry-on cap the headphone is nearly 2 percent of your whole allowance and the earplugs are not measurable against it.

Fit is most of the performance, and no rating captures it

Every attenuation figure above is a laboratory number achieved with a correct seal. A foam plug that has not been rolled thin and inserted deep enough performs nothing like NRR 33, and this is the usual reason people conclude earplugs do not work.

• Foam: roll it thin between finger and thumb, pull the top of the ear up and out, insert, and hold for a few seconds while it expands.
• Filtered plugs: the seal is set by the tip size, not by compression. Alpine publishes a 9–12 mm earplug diameter; Loop ships four tip sizes. Use the largest that is comfortable.
• The check: your own voice should sound noticeably louder and deeper inside your head. If it does not, the seal is not there.
