Most Swimmers Accept Ear Infections as Part of the Sport. They Are Not.

Pool water exposes your ear canal to bacteria with every session. The infection threshold starts the moment you climb out. Every swim without protection is a step closer to an infection that doesn’t need to happen.

“Your ear felt blocked and full on the drive home. You told yourself it would clear — it always does eventually. But every time it comes back a little sooner and stays a little longer. Swimmer’s ear is the only infection you accumulate one good session at a time, without noticing, until your ENT starts talking about canal damage. The pool will always be there. Your ear canal does not repair itself.”

Questions? We've got answers.

This is the right question to ask before you buy. Cheap putty and foam plugs create a loose barrier that shifts in warm water and degrades under the pressure of a flip turn — they reduce water entry, they don’t stop it. Watersafe+ uses a sized medical-grade silicone seal that conforms to your canal geometry. The seal holds under water pressure, directional force, and temperature change. Multiple competitive swimmers have tested them through full training sessions and race events with zero water ingress. If your current plugs are letting water through, it is a fit and seal issue, not an earplug category issue.

Complete barrier protection against water entry when correctly fitted — and the fit is the critical variable. Watersafe+ is designed around the AR KI TECH sizing system because canal diameter varies by up to 40% between individuals. A generic one-size plug creates gaps even when it appears to be seated. A correctly sized Watersafe+ seal eliminates the gap entirely. The NHS and ENT guidance is consistent: swimmer’s ear is almost entirely preventable with appropriate barrier protection. Watersafe+ does not make swimming safer in theory. It makes it safer in practice, session after session.

Yes — and this is central to how Watersafe+ is designed. It is not a noise-reduction earplug. The silicone seal prevents water ingress, not sound transmission in air. You hear coaching instruction, starting signals, and lane communication at normal volume. There is a mild reduction in very high frequencies in loud poolside environments, but training instruction and race management communication are clear throughout. Competitive swimmers in squads wear them through full sessions without missing a word of poolside feedback.

Less strange than the blocked ear you spend the rest of the week dealing with. Watersafe+’s medical-grade silicone sits flush at the canal entry — significantly less visible than most swimmers assume, and the swimming community has largely normalised hearing protection at club level. Coaches, masters swimmers, and parents of club juniors have driven the shift. The swimmers who didn’t start early, and wish they had, are documented in every ENT waiting room. The stigma is fading. The canal damage is not.

It is not too late to stop the cycle. Recurring otitis externa affects millions of swimmers and the most consistent ENT advice is: the moment you have a pattern of swimmer’s ear, barrier protection becomes urgent, not optional. The canal skin already damaged by past infections is more susceptible to the next one — each recurrence leaves the ear slightly more vulnerable. Watersafe+ breaks the cycle by removing the cause rather than treating the symptom. Many swimmers with chronic swimmer’s ear report that after switching to properly fitted silicone earplugs, the recurrence stops entirely.

Two fundamental differences. First, seal integrity: pool putty deforms to fill the outer ear bowl, not the canal. It creates a loose barrier that softens in body-temperature water and shifts on a flip turn. Watersafe+ is precision-sized silicone that seals the canal entry directly — a consistent, repeatable seal that doesn’t degrade mid-session. Second, fit: putty requires you to press material into your canal, which creates pressure and often leaves residue. Watersafe+ sits flush without insertion pressure. The putty at the pool reception costs less. It works like it costs less.

Faster than most swimmers expect. Otitis externa develops when bacteria — most commonly Pseudomonas aeruginosa — multiply in water trapped in the ear canal after swimming. The canal’s warm, moist environment post-swim is ideal for bacterial growth. The temporary blocked feeling you experience after a session is your ear canal signalling that water is trapped. When the feeling fades, the bacterial load has not fully cleared — each session without protection leaves a residual risk that compounds over a season. Regular swimmers without barrier protection typically develop their first infection within weeks of starting a high-frequency training schedule.

Yes — comfort across extended wear is a core design requirement. The flush, low-profile silicone sits without the pressure buildup that makes putty or expanding foam painful within an hour. The majority of Watersafe+ users are competitive swimmers and triathletes who wear them through full training sessions of 90 minutes or more. Open-water swimmers wear them through multi-hour events in cold water without discomfort. Our return rate sits at around 3%, which tells you the fit holds up across extended and repeated use.

Yes. Rinse with clean water immediately after use to remove chlorine, salt, or bacteria. Allow to air dry fully before storing — never store damp in a closed case. Once a week, wash with mild soap and warm water. Medical-grade silicone doesn’t absorb chlorine, doesn’t degrade in salt water, and doesn’t lose its shape from repeated washing. Do not use alcohol-based cleaners as they degrade silicone over time. One pair lasts up to 12 months of regular use — they will outlast the season and the one after it.

Each Watersafe+ set includes your earplugs in medical-grade silicone, a compact carry case, and a Fit Guide. Add AR KI TECH at checkout for precision ear sizing — snap two photos of your ears and we match your exact canal size before dispatch. Free UK delivery. Returns and exchanges are free if the fit isn’t right — though with AR KI TECH sizing our return rate sits at around 3%, so it rarely comes to that. Order before your next session.

TECHNO LEGEND & HEARING PROTECTION ADVOCATE

“I have spent my career in environments that destroy hearing. The only reason I still hear the detail in a mix after 30 years is that I treat ear protection as non-negotiable — not optional. Whether you are in the water or in front of a speaker stack, you have one set of ears. BOLLSEN builds protection that actually works and actually gets used. Treat your hearing accordingly.”

Michael Klein & Tanja Rhein

“Swimmer’s ear is one of the most preventable conditions we see, and yet recurrence rates remain high because patients treat it with drops rather than addressing the cause. A properly fitted silicone earplug that seals the canal eliminates the mechanism entirely. The difference between a well-fitted earplug and generic pool putty is the difference between protection that works and protection that creates a false sense of security. Swimmers who can train without interruption actually wear their earplugs. That is what stops the cycle.”

Used these through a full competitive season — training five days a week for six months. Rinsed them after every session, kept them in the case between swims. Zero degradation, still sealing exactly the same as session one. Built to last in ways pool putty simply isn’t.
Tom Davies, Club Swimmer – Leeds / Trustpilot
Open-water swimmer, been using these in the sea and pool for 14 months. Same pair, same fit, same seal. I compared them to two other swimming earplugs before settling on Bollsen. The only one where the silicone hasn’t started to feel tacky or lose its shape.
Ellie Watson, Masters Swimmer – Bristol / Google
Triathlete, wear earplugs for open-water sessions and race events. Watersafe+ has outlasted every other brand I’ve tested by a significant margin. Six months of regular use across pool and sea, the seal performance hasn’t dropped once. Nothing else at this price point holds up.
Ryan O'Brien, Triathlete – Dublin / Trustpilot
Swam year-round in the sea for three years. Previous winters I’d have two or three ear infections between October and March. First winter using Watersafe+ — not one. Woke up after swims in 8°C water with no blocked feeling at all. First time that’s happened in years.
Sarah Hill, Open Water – Cornwall / Trustpilot
Swimming coach, squad of 24 junior swimmers. Two seasons ago I introduced Watersafe+ for the whole group. Ear infections dropped by over 80% across the squad in the first six months. Parents noticed immediately. The swimmers who didn’t use them accounted for all the remaining infections.
James Holden, GP and Swimmer – Edinburgh / Google
I have mild exostosis from years of sea swimming. Started using Watersafe+ six months ago on my ENT’s advice. Sessions that used to leave me with three days of blocked feeling now leave nothing by the next morning. The water stays out. I genuinely cannot explain why I waited this long.
Clare Murphy, Swim Mum – Manchester / Trustpilot
Used putty before — uncomfortable within 40 minutes and constantly shifting during turns. Watersafe+: zero discomfort across a full 90-minute training session. Forget they’re in. Don’t notice them on flip turns. That’s what you need when you’re trying to focus on technique.
Kat Reynolds, Competitive Swimmer – London / Google
Wore these through a full open-water event — 5km in choppy conditions. Swim cap on, waves from every angle. They didn’t shift once. Previous earplugs were halfway out by 2km and uncomfortable long before that. Watersafe+ stayed put the entire race without me touching them.
Tom Braun, Open Water – Brighton / Trustpilot
Narrow ear canals — every earplug my son has tried has either fallen out or been too painful to wear for a full session. AR KI TECH sized him correctly on the first attempt. He wore them through a two-hour gala with zero pressure and zero movement. First pair that has ever actually worked for him.
Lucy Chen, Swim Parent – Cambridge / Google
Ordered Thursday before a Sunday open-water event. Arrived Saturday morning. Sizing guide was clear, fit was right from the first wear. Nothing to contact them about — which, when you’re ordering for a specific race, is exactly what you need.
Mark Thompson, Triathlete – Birmingham / Trustpilot
Wrong size came. Emailed support that evening, had a response within a few hours. Replacement dispatched next morning, arrived with two days to spare before my next open-water swim. Sorted quickly and without any fuss. Impressed.
Fiona Clarke, Masters Swimmer – Glasgow / Google
Asked before buying whether Watersafe+ would work for someone with existing mild exostosis. Got a detailed, honest reply within a few hours — not a sales pitch, actual useful information. Bought based on that. The earplugs have been exactly as described.
