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 £29.95?
Water trapped in the ear canal after every session is the reason a lot of people quietly stop swimming. It sits there for hours, it is uncomfortable, and it takes the pleasure out of the pool.
A single BOLLSEN Watersafe+ costs just 30p 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 30p, 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 of that muffled, sloshing feeling for hours afterwards. No more skipping the pool because you know what’s coming next.
Just clean, dry ears every session.
The Last Swimming Earplugs You’ll Ever Need to Buy

AI Online Ear Measurement Service (AR KI Tech®)
Custom earplugs from an audiologist cost £150 to £250 per pair. BOLLSEN Watersafe+ is a fraction of that. Thanks to the conical 2-lamellae design, the earplugs perfectly adapt to your ears, regardless of their shape. The soft silicone adapts to your ear canal and they feel custom-made from the very first swim.
Standard fit: Medium ears
The standard version fits most medium-sized ear canals. Works well for the majority of adults straight out of the box.
Custom fit: Large or small ears
Ears too large or small for standard? Use our AI ear measurement. Send two photos of your ears. Our AI finds your exact size. Perfect fit guaranteed, no audiologist appointment needed.
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 keep my ears dry?
Yes, when they seal properly. The conical 2-lamellae design closes the ear canal, so water does not get in during swimming, diving or showering. Keeping the canal dry is the whole job of the plug, and the right size is what makes the seal reliable. Use the AI ear measurement if you are unsure. If your ears keep giving you trouble after swimming, that is worth raising with a GP or an audiologist.
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 is a well-documented phenomenon in cold water and open water swimming. Keeping cold water out of the canal removes the trigger, which is what a sealing earplug does. If the dizziness persists, or it happens outside the water, see a GP.
Can I use them after ear surgery, or with grommets or a perforated eardrum?
That is a question for your GP or ENT specialist rather than for us. Watersafe+ is a swimming earplug, not a medical device, and we are not in a position to tell you what is safe for your ears. What we can tell you is what it does: the two-lamella silicone seals the ear canal to keep water out, and it is washable and reusable up to 100 times. Take that to your clinician and let them advise you.
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 AI ear 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 +650 verified reviews. But you don’t have to take our word for it.

Fantastic
These are the best earplugs I've tried for swimming. They stay in well during my whole swim and keep the water out.
Translated · Show original
Fantastiske Det er de bedste ørepropper jeg har prøvet til at svømme med. De sidder godt under hele min svømning og holder vandet væk.
Watersafe earplugs for swimming
Top quality. The only problem is the colour. Why blue? If you ever lose the earplugs while swimming, a different colour would make much more sense, because then you'd actually be able to find them.

Watersafe Ohrstöpsel zum Schwimmen Top Qualität. Einziges Problem ist die Farbe. Warum blau? Wenn man die Ohrstöpsel beim Schwimmen mal verliert, wäre eine andere Farbe viel sinnvoller, da man sie dann auch finden würde.
Not Made For My Ears
A great product I’m sure for some. However, my ears just didn’t like them and kept falling out even though I did the AI ear measurements. I definitely think it’s my ears and not the product. Tom was excellent and incredibly helpful through the process. 👏🏽
Good earplugs
Good earplugs - they are a bit hard to get properly into the ears though - even though I followed the instructions. Got a tiny bit of water in my left ear canal. But otherwise they seal well and stay in place when you have your head under water.

Fine ørepropper Fine ørepropper- er dog lidt svære at få sat ordentligt i ørerne - selv om jeg har fulgt anvisningen. Fik en anelse vand i venstre øregang. Men slutter ellers fint og bliver siddende når man har hovedet under vand.
Excellent Product
Easy to use. Most effective product.
Will buy again
The best, really
I admit that I was extremely skeptical - I first saw an ad for these earplugs on Instagram, and there are SO many companies selling overpriced trash on social media. But I’ve tried just about every other earplug solution for swimming, and I was desperate. When they arrived, I took my new Bollsen plugs for a swim, being sure to pack my other functional but imperfect (Speedo and Mack’s) backups. I’m not afraid to say the Bollsen earplugs are superior in almost every way. They may look and feel flimsy, but they are extremely easy to use and they don’t hurt my ears. For the first time in years, I had ZERO leaks! Do I wish they were a bit cheaper - yes. And they need a better storage container that allows water to drain and evaporate. But overall, these are the best earplugs I’ve ever used. I’m glad I bought two sets!
they work
These do a great job at keeping the water out. I swim 5 days a week these don't interfere at all with wearing a cap don't stick out. I used them in my 1500m race and they stayed in and comfortable. My old Aqua seals were discontinued and I tried all the store bought brands. those kept leaking water and not staying in and was having to buy drops etc to prevent the ear infections. When these first arrived I didn't think they were going to work but they do once you get used to how they twist in. After a week of swimming they have been consistent at keeping water out. I used the custom option i had some trouble sending in the pictures but was able to contact customer service and get an email to send them to. not sure if that made a difference but it was the option I chose. I would definitely order again when I need to replace. They do come with a case except the case is not vented so they can't air dry. I use an old case with holes instead so that they dry out in between uses.
Very satisfied

Questions & answers
Can these be worn with a swim cap? We have had custom plugs made in the past and once the cap is on, they hurt as they press onto her ear.
Answer from BOLLSEN
Thank you for your question.
Yes, our earplugs can be worn with a swim cap. Unlike many custom-made plugs, our earplugs feature an ergonomic, low-profile design that sits comfortably in the ear without protruding excessively. This helps minimise pressure from a swim cap and makes them comfortable to wear.
For the best possible fit, we also offer our AR-KI TECH online ear measurement service, which helps us determine the most suitable size for your ears. A proper fit is especially important for comfort when wearing a swim cap.
Please keep in mind that comfort can vary depending on the shape of the ear and how tightly the cap fits. If you have any other questions, we’ll be happy to help!
Can these for my 8 year old daughter or are they just adult size? She trains several days a week and keeps getting awful ear infections so looking for a way to stop it happening again
Answer from BOLLSEN
Hello,
Thank you very much for your message.
Yes, for an 8-year-old child we would recommend our Kidz earplugs rather than the standard Watersafe earplugs.
The Kidz model is designed specifically for smaller ear canals, so it provides a more suitable and comfortable fit for children. They are also designed for swimming and help blocking the amount of water entering the ear canal.
In addition, the Kidz earplugs provide noise reduction of up to 24 dB SNR, so they can also be useful in noisy environments, travel, events, or other situations where reducing surrounding noise may be helpful.
For a child who trains in the water several times per week, the smaller size and water-resistant design would generally make the Kidz model the more appropriate choice.
If you have any further questions, need help, please feel free to contact us at any time. We will be very happy to help.
Best regards,
How many times can you use each pair
Answer from BOLLSEN
Hello,
Thank you for your question.
Based on our internal testing and customer feedback, each pair can typically be used at least 100 times.
With proper care, they can often last considerably longer. We recommend cleaning them regularly, allowing them to dry completely after each use, and storing them in their case in a cool, dry place away from direct sunlight and excessive heat.
The actual lifespan can vary depending on how frequently they are used and how well they are maintained.
Best regards,
Hi in jan this year I had sudden sensory hearing loss, in my left ear ,they are healed from treatment but I don't want to get water in my ears, are these ok for me to ware and are they comfortable Thank you
Answer from BOLLSEN
Hi,
Thank you for your question.
Our Watersafe+ earplugs are made from soft medical-grade silicone and are designed to create a secure seal to keep water out of the ear canal. They are specifically intended for swimming, bathing and other water activities.
For the best possible fit, especially if keeping water completely out is particularly important for you, we would recommend adding our AR KI TECH online ear measurement. You simply provide photos of your ears, and the measurement helps determine the most suitable size for your ear canals.
As you’ve experienced sudden sensorineural hearing loss, however, we would recommend checking with your ENT specialist or doctor before swimming, particularly if there are any remaining concerns about your ear.
Kind regards
If I buy 2 set of water earplugs with AI measurement can I reorder at a later date without paying for AI fitting again?
Answer from BOLLSEN
Hi,
Yes, absolutely! Once you have completed the AR KI Tech measurement, we can keep your sizing information on file for future orders, so you won’t need to go through the measurement process again.
When placing a future order, we recommend contacting our Customer Support team first. We’ll be happy to help you use your existing measurement and explain how to apply it to your new order.
Have a lovely day!
