3rd ear infection in 4 months from open water swimming. GP said stop or wear earplugs. Tried two other brands — both let water in. Watersafe+ sealed first time. Back training within a week, zero infections since.
Daughter had recurring otitis externa every time she trained. Coach recommended we try Watersafe+. 8 weeks of swim squad, 5 sessions a week, not a single infection. The seal holds even when she dives off the block.
Had to stop swimming for 6 weeks after a bad ear infection. ENT told me I had to use proper earplugs or give up the pool entirely. Watersafe+ solved it. Back to 4 sessions a week. No water in, no issues.
Training for the English Channel — hours in open water every week. Tested 4 earplug brands over 3 months. Only Watersafe+ held a full seal through cold water, swell, and rough conditions. Just ordered my third pair.
Masters swimmer, 5 sessions a week including butterfly sets. Previous plugs fell out on every tumble turn. Watersafe+ stays locked in through 60+ turns per session. Material is still intact after 4 months of daily use.
Tried moldable silicone putty, foam, and two flanged designs before these. All degraded or lost their seal within weeks. Watersafe+ showed no deformation after 80+ uses. The silicone quality is immediately obvious.
Triathlete — open water swim leg in every race. Needed earplugs that block water but still let me hear safety signals from the kayakers. Watersafe+ gets the balance right. Water out, ambient awareness in.
Use them every single day in the shower after a perforated eardrum. GP said water in the ear is not an option. 6 months of daily use, seal holds every time. Also bought the AR KI Tech version — perfect fit immediately.
Cold water open water swimmer. Was getting dizzy after longer swims — cold water on the eardrum. Watersafe+ eliminated it completely. 14 open water sessions since, zero vertigo. Didn’t realise earplugs could fix that.
Wrong size delivered. Contacted support at 9pm, reply within 4hrs. Replacement shipped next morning, arrived in 2 days. Full resolution in under 72hrs with no return required from me.
Asked about compatibility with tympanostomy tubes before ordering. Received a detailed, medically accurate response within 3hrs. Ordered the same day. That level of product knowledge is rare for an online brand.
Ordered from Portugal — arrived in 4 business days, packaging intact, sizing guide included. Received a follow-up email after 7 days to confirm fit. Rare post-sale care from any brand.

Can Earplugs be worth £26.95?
A single ear infection means days off swimming, a GP visit, and antibiotics. Recurring swimmer’s ear can end a season entirely or worse, force you to give up the pool for good.
A single BOLLSEN Watersafe+ costs just 27p per swim over 100 uses. Grab the 4x Pack and that drops even further. Less than the price of a coffee to protect your ears all season.
For 27p, the water stays out. It’s not even a decision.
Swim Again. Without the Aftermath.
BOLLSEN Watersafe+ keeps water out from the very first swim.
No more that muffled, sloshing feeling for hours after. No more skipping the pool because you know what’s coming next.
Just clean, dry ears every session.

Frequently Asked Questions About Swimming Earplugs
Will they actually stay in during flip turns and dives?
Yes. This is the question every swimmer asks first, and for good reason. The conical 2-lamellae design locks to your ear canal rather than sitting loosely inside it. Body heat causes the silicone to adapt to your exact canal shape within the first few minutes, forming a secure seal. Customers report zero slippage through butterfly sets, tumble turns, and open water swell. The tab gives you full control for easy removal without tugging.
Will they actually prevent swimmer's ear?
Yes, when they seal properly. Swimmer’s ear (otitis externa) is caused by water sitting in the ear canal and breaking down the skin’s natural protection. Watersafe+ blocks water from entering the canal entirely. No water in means the bacteria in pool water and open water have no route to cause infection. Customers who switched to Watersafe+ after recurring infections consistently report zero ear infections from that point. If you’ve had recurring swimmer’s ear, getting the right size is essential. Use AR KI Tech if you’re unsure.
Can I still hear my coach and safety signals in the water?
Yes. Watersafe+ is not designed to block all sound. The 2-lamellae silicone seals water out while still allowing approximately 24 dB of ambient sound through. In practice, you can hear your coach calling instructions from the poolside, whistles, and safety signals from kayakers in open water. What you lose is the underwater roar. What you keep is everything you actually need to hear.
Why do I get dizzy after cold water swims? Will earplugs fix it?
Very likely yes. Cold water entering the ear canal triggers something called caloric vestibular stimulation — cold water hitting the eardrum disrupts the balance signals your inner ear sends to your brain, causing vertigo and disorientation during and after long swims. It’s a well-documented phenomenon in cold water and open water swimming. Blocking cold water from reaching the eardrum removes the trigger. Several of our customers discovered this was the cause of their post-swim dizziness only after Watersafe+ eliminated it entirely.
Are they safe to use with ear tubes or a perforated eardrum?
Watersafe+ is doctor-recommended for exactly this use case. If you have tympanostomy tubes (grommets), a perforated eardrum, or a post-surgical ear, water entering the canal is a serious risk. Watersafe+ forms a medical-grade silicone seal that keeps water out completely, making it safe for showering, bathing, and supervised swimming. Always confirm with your ENT or GP first, particularly in the early stages of recovery.
How do I insert them correctly?
Place the earplug on the tip of your finger and gently twist it into your ear canal with a slight rotating motion. It should seal the canal fully without needing to be forced. Once inserted correctly, you’ll feel the ambient sound reduce slightly. The tab sits flush outside the canal for easy removal. For the best seal, make sure you have the right size. If the standard version doesn’t feel secure, the AR KI Tech measurement will get you the exact fit for your ear canal.
What if they leak or don't work for me?
Nothing. You have 40 days to test them in the pool, in open water, in the shower. If they leak or you’re not satisfied for any reason, contact us and we’ll refund you in full. No questions, no forms, no back and forth. Over 1 million customers and +330 five-star reviews. But you don’t have to take our word for it.

Customer Reviews
Training Block Complete. Race Season Uninterrupted.
I compete in triathlon and had DNSd two events the previous season because of ear infections picked up in open water training — each one meant a week out of the water right when I needed to be training hardest. I was meticulous about Watersafe+ from the first session of this season. Zero infections across eight events and a full training block. I finished my target race in a personal best time and credit the uninterrupted preparation as a significant factor.

Swimmer's Ear Fixed. Eight Months and Counting.
My son is a competitive swimmer training four days a week and for eight consecutive months we'd had monthly GP visits for swimmer's ear. It was affecting school, training and his general mood. Watersafe+ junior fit properly and — critically — he didn't complain about wearing them, which every previous attempt had run into. Eight months have now passed without a single GP visit for anything ear-related. The relief is enormous.

Grommets Intact. ENT Happy. Mum Relieved.
My eleven-year-old had grommets fitted and the ENT consultant was clear that pool water ingress needed to be avoided or the tubes could be damaged and the procedure repeated. I'd had to withdraw her from the swim team which was upsetting for everyone. Watersafe+ provided the seal the ENT had said was necessary. At the six-month review both grommets were intact and infection-free. She's back in the swim team and competing again.

Finally Cracked the Swimmer's Ear Problem
I swim competitively and had been through four ear infections in a single training block a nightmare when you're training five days a week and each infection means time out of the pool. My coach suggested trying Watersafe+ and I admit I wished I'd done it sooner. I completed a full 16-week block without a single infection. The fit was secure enough that I stopped thinking about it and just focused on swimming.

Full Competition Season With No DNS Results This Year
My 12-year-old daughter competes in swimming galas and the previous season saw six missed competitions due to recurring otitis media each one a real disappointment after weeks of training. Watersafe+ changed everything. She wore them at every session and gala, and made it through a 22-event season without missing a single one. Watching her finish every race was something I'd started to take for granted that she'd never be able to do.

230 Sessions. Zero Ear Infections. One Full Season.
"I do masters swimming at a 50m county pool five sessions a week — and the previous season had been disrupted by seven ear infections, each requiring drops and time out of the water. It had started to badly affect my race preparation. I wore Watersafe+ from the first session of this season without exception. Zero infections across 48 weeks and over 230 swims. My club times improved significantly, partly, I think, just because I was actually in the water consistently."

Five Ear Infections in One Term — Then Zero
My seven-year-old daughter picked up five ear infections in a single swim term and every time it meant time off school, GP visits, and a miserable few days. I'd tried cheaper alternatives that either didn't seal properly or fell out after a length. Watersafe+ fitted well and more importantly — stayed in. The following two terms passed without a single infection. My daughter doesn't complain about wearing them and I'm a total convert.

Otitis Externa: Three Times in One Season
I train for triathlons and do four swim sessions a week — a mix of open water and pool. I'd had three bouts of otitis externa in a single season, each one setting my training back by a week or more. I switched to Watersafe+ and wore them for every session without exception across a full 20-week prep block. No infections. My coach said I was the most consistent in training I'd ever been. I think a lot of that came down to not losing weeks to ear problems.

Ear Plugs for Swimming
I bought 2 pairs for my child to use in her swimming training. Trying to prevent recurrent ear infections. It took a few attempts to get used to wearing them. We had one instance where one of the ear plugs fell out in the pool (but she found it!). We think this is because one of the plugs is slightly squashed (was like that when arrived) so doesn’t fit quite correctly. We swapped for the other pair and was fine. Bit disappointed that one ear plug can’t be used, but other than that good product. If anyone knows how the squashed one can be corrected let me know.

Ohrstöpsel fürs Schwimmen
Die Stöpsel sind sehr gut ins Ohr einzubringen. Etwas Wasser bleibt im Ohr. Rutschen ab und zu aus dem Ohr.
Vielleicht gibt es unterschiedliche Größen. Habe mir 3 Paar gekauft.
