Swimming earplugs · 2026 · Pool and open water
The best earplugs for swimming.
With a swim plug essentially one thing matters: does it stay put through a flip turn. Anything that shifts there is just riding along in your ear from then on. We wore twenty pairs for ten weeks in the pool and in open water. Here is the order.

Why the turn decides it
Water does not get in on the first length. It gets in when your head snaps around at the wall.
Floating quietly, almost everything seals. So our testers swam twenty flip turns with each pair and only then checked where the plug was. Of the twenty pairs, eight had shifted and three had come out completely.
We scored sealing after a turn, behavior under a swim cap and one-handed insertion — that last one matters more than it sounds at the pool edge with wet hands.
Is a plug enough on its own?
Keeping water out of the ear is one of the ordinary precautions for swimming. The CDC lists a bathing cap, ear plugs, or custom-fitted swim molds as ways to keep water out of your ears. If you have an actual problem with your ear, a physician decides what to do about it — a product test does not answer that, and neither do we.
What about the pool being loud?
An indoor pool is a hard-surfaced room full of noise and these plugs take about 24 dB off it, which is a side benefit rather than the point. If quiet is what you are after rather than dry ears, the general sleeping and work plugs in this test are the better buy.
Twenty turns, twenty times still seated.
See our #1 ›The test
After ten weeks — three pool sessions a week, two open-water swims, weekends with kids — the BOLLSEN Watersafe+ were the only pair that never shifted once.
With a swim plug the question is not whether it seals. It is whether it still seals after the twentieth turn.
Two flanges instead of one seal
Two flexible flanges sit one behind the other inside the canal. If the first moves, the second still holds. Models with a single pad resting on the outer ear have no such reserve, and the test showed it.
They do not shift under a cap
A swim cap stretches over the ear and drags a protruding stem out of position. This pair has no stem, so the cap could be pulled over without needing an adjustment afterward.
No drying routine
Rinse them, put them in the case, and they dry themselves. The wax plugs started crumbling in week three of the test, and foam simply would not go back in once wet.
Ten weeks of pool and lake. The same pair throughout.

How we tested
20pairs bought at retail
10 weeksof pool and open water
3criteria: sealing after a turn, behavior under a cap, wet-handed insertion
We bought twenty pairs at retail and used them for ten weeks: three pool sessions a week, two open-water swims and weekends with kids. With every pair we swam twenty flip turns and only then looked at where the plug was. None came from a manufacturer.
The winner’s attenuation was measured by an independent German laboratory to EN 352-2: 24 dB overall, most of it at high tones. It is a passive plug: it keeps water out and quiets sound without separating it. Results vary from person to person.
TrustScore comparison · 7 September 2026
Four earplug brands on Trustpilot. One is rated Excellent.
Trustpilot gives every company it lists a TrustScore out of 5 and a rating band. We looked up the branded reusable earplugs that appear in our tests. Only one of them reaches the top band, Excellent.
| Rank | Brand | TrustScore |
|---|---|---|
| 1 | BOLLSEN Hearing Protection | 4.3Excellent |
| 2 | Alpine Hearing Protection | 4.1Great |
| 3 | Flare Audio | 4.0Great |
| 4 | Loop Earplugs | 3.6Average |
Why 4.3 and not 5.0
Excellent starts at 4.3 on Trustpilot. A perfect 5.0 usually means a company has collected very few ratings, so one more review moves the score. BOLLSEN is the only brand here that reaches it, on a profile you can open and check yourself.
Method. TrustScores read from each brand’s public Trustpilot profile on 7 September 2026. Where a brand runs several country profiles, we used the one with the most reviews, so every row shows a global profile rather than a local one. Brands with fewer than 250 reviews are not shown. Star ratings are the ones Trustpilot displays, rounded to the nearest half star. Trustpilot bands: Excellent 4.3 to 5.0, Great 3.8 to 4.2, Average 3.0 to 3.7. Scores change as new reviews come in.
