Every Session Puts Water in Your Ears. Over Time, That Adds Up.
Swimmer's ear. Surfer's ear. Recurring infections that disrupt your training and, left unchecked, cause lasting damage. The fix is not complicated — but it starts with a seal that actually holds. Bollsen Watersafe+ is built with a dual-flange design certified to 3 metres depth, engineered to stay in during flip turns, duck-dives, and everything in between.

Pool Training
The dual-flange seal holds through every flip turn. When your swim cap applies pressure, Watersafe+ locks firmer — not looser — so you finish the set, not fix your earplugs.
Open Water & Triathlon
Rated to 3 metres depth. Whether it is a lake, sea, or lido, the waterproof barrier holds through entries, turns, and the kind of conditions that beat standard plugs in seconds.
Surfing
Surfer's ear is caused by chronic exposure to cold water and wind. It is progressive and irreversible without surgery. A seal that holds through wipeouts and duck-dives removes the exposure entirely.
Consistent Protection
Up to 100 uses per pair. Washable with water and mild soap. Medical-grade silicone that stays soft and maintains its seal session after session — no degradation, no gunk buildup.
Watersafe+ vs. Standard Swimming Earplugs
Most swimmers have tried the cheap silicone plugs from a sports shop. Here is the honest difference.
| Standard Silicone Plugs | Bollsen Watersafe+ | |
|---|---|---|
| Seal during flip turns | ✕ Shifts when a swim cap applies pressure — the seal breaks mid-turn | ✓ Dual-flange locks at the canal entrance. Cap pressure holds it firmer, not looser |
| Depth-rated waterproofing | ✕ Splash-resistant at best — not designed for dive entries or submersion | ✓ Certified seal to 3 metres depth. Built for everything from lap swimming to surfing |
| Material safety | ✕ Often PVC or unspecified rubber with no safety certification | ✓ Medical-grade silicone. BPA-free, PVC-free, latex-free. Hypoallergenic |
| Reusability | ✕ Degrades after a few uses. Most are single-use or deform quickly | ✓ Up to 100 uses per pair. Washable with water and mild soap |
| Independent certification | ✕ Self-declared or no testing at all | ✓ Tested by PZT GmbH, Notified Body No. 1974. SNR 24 dB verified |

Questions? We've got answers.
Is swimmer's ear actually that serious?
Otitis externa — swimmer's ear — causes pain, discharge, and temporary hearing reduction. If it keeps coming back, it becomes chronic and more difficult to treat. For surfers and regular cold-water swimmers, the longer-term risk is exostosis: bony growths that gradually narrow the ear canal. This condition does not reverse on its own and typically requires surgery to correct. Prevention is simple. The damage, once done, is not.
How is Watersafe+ different from the silicone plugs I can buy in a sports shop?
Most swimming earplugs are a single dome or cylinder shape. When your swim cap presses against them at an angle during a flip turn or dive entry, they can shift inward or out, breaking the seal. Watersafe+ uses a dual-flange shape that locks at the entrance of the ear canal. This means cap pressure actually holds it firmer — not looser. It is also independently certified waterproof to 3 metres, rated SNR 24 dB by PZT GmbH (Notified Body No. 1974) — not self-declared splash resistance.
Will they stay in during flip turns, duck-dives, and surf sessions?
Yes. The dual-flange seal is rated to 3 metres depth and designed specifically for high-movement conditions. Flip turns, open-water entries, wipeouts, and duck-dives are exactly the scenarios they are built for. If they shift during normal pool use, the most common cause is sizing. If you are unsure which size is right for your ears, AR KI TECH can help.
What is AR KI TECH and do I need it?
AR KI TECH is Bollsen's AI ear-fitting service. You upload two photos of your ears and the system analyses your canal dimensions to recommend the correct size. It brings our return rate down to 3%, against an industry average of 15 to 20%. If you have struggled to find earplugs that fit properly in the past, it is worth adding. You can order Watersafe+ with AR KI TECH at checkout.
What if they do not work for me?
Every Watersafe+ order comes with a 40-day money-back guarantee. If they do not do what they say — keep water out, stay in during your session — return them within 40 days for a full refund. No forms. No questions. Try them for a month of proper training before you decide.

Two independent voices on why proper ear protection matters in and out of the water.
I perform in front of enormous speaker systems. I know precisely what sustained exposure does to hearing over time — and I know most people do not take it seriously until it is too late. The Bollsen design is the only one I recommend: it fits, it holds, and it does not let you down when it matters. The principle in water is identical to the one on stage — if the seal fails, you pay for it later.
Swimmer's ear and surfer's ear are among the most preventable hearing-related conditions we encounter. They result from chronic exposure — not a single bad session. Most swimmers underestimate the cumulative risk until infections become recurring, or the canal starts to narrow. A consistent waterproof seal removes the exposure entirely. Watersafe+ achieves what generic plugs do not: it holds through pressure, impact, and sustained movement in water.
Over 1,000,000 People Trust Bollsen. Here Is What Swimmers and Surfers Say.
I swim four times a week and had chronic ear infections for two years. They stopped within the first fortnight of using Watersafe+. They hold through tumble turns without me touching them once.
Surfed in two-metre swell last week. Not once did I need to adjust them. Every other pair I have tried was out after the first wipeout. These are a different category entirely.
My daughter is on a county swim team and does flip turns all day. She comes home with no ear pain now. We would not go back to anything else.
They sit so flush you forget they are there. Other plugs always protruded and fell out the moment I turned underwater. Not these — they disappear and just do their job.
The soft silicone is nothing like foam. My ears used to ache after a long training session just from cheap disposables. These are genuinely comfortable for a full hour in the water.
I used the AR KI TECH sizing option. The recommended size arrived and fitted perfectly the first time. I have never had earplugs that did not need a second attempt to seat properly.
Tried Loop, tried Alpine, tried the cheap silicone sets from the sports shop. Watersafe+ is the only pair that stayed in for an entire open-water swim without me touching them once.
I was sceptical. Another earplug that "stays in" — sure. Then they survived a proper duck-dive session in the sea and I was converted. Nothing else I have tried comes close.
The metal case alone beats everything else I have owned. But it is the seal that matters. Consistent, session after session — exactly what the description promises.
Ordered Monday, delivered Wednesday. Well packaged, clear instructions, and the metal case is a genuinely nice object. Ten out of ten from start to finish.
I had a sizing question about my teenager. They replied within a few hours with a genuinely useful answer, not a template response. That kind of service is hard to find.
Used the 40-day guarantee when I ordered the wrong size. No hassle, no questions, exchanged within the week. Exactly the kind of brand that backs up what it says.
