Every splash in the pool, every cannonball, every swimming lesson can turn into a painful ear infection for a child prone to otitis externa. The real challenge isn’t finding earplugs—it’s finding plugs small, soft, and secure enough for tiny ear canals that won’t fall out mid-lap or cause discomfort. Kids have narrow, delicate ear canals that standard adult plugs simply cannot fit, making the search for a truly pediatric-friendly solution feel like an endless trial of sticky putty and failed seals.
I’m Mohammad — the founder and writer behind ProteinJug. I’ve analyzed dozens of earplug formulations and pediatric swimming accessories, comparing moldable silicone tackiness, waterproof ratings, and the specific sizing that matches a child’s anatomy to identify which plugs actually prevent water intrusion without causing pain.
Below you’ll find five tested, parent-approved candidates that prioritize waterproof sealing, soft hypoallergenic materials, and kid-friendly fit, helping you find the right best swimming earplugs for kids that will actually stay put during play.
How To Choose The Best Swimming Earplugs For Kids
Selecting the wrong earplugs can lead to water leakage, discomfort, and even increased risk of infection. The ideal pair balances material softness with a reliable seal that matches your child’s specific ear canal size and activity level.
Moldable Silicone vs. Pre-Formed Flanged Plugs
Moldable silicone putty is the preferred choice for children because it customizes to their unique ear shape without needing to be inserted deep into the ear canal. This reduces the risk of pushing earwax deeper or irritating a sensitive eardrum. Pre-formed flanged plugs with multiple fins require precise insertion depth and correct size selection, which can be challenging for younger children but offer a more secure mechanical seal once fitted properly.
Size and Fit: Matching Child’s Age and Ear Canal
A child’s ear canal diameter changes significantly between toddlerhood and early teens. Look for products offering multiple size options within a single pack, allowing you to find the correct fit for each ear. Moldable putty solves this by being a one-size-fits-most solution, while flanged plugs must be carefully matched to the child’s age and gender—a wrong size leads to leakage or the plug falling out mid-swim.
Waterproof Certification and Noise Reduction
While a Noise Reduction Rating (NRR) around 22dB is typical for swimming plugs, the waterproof seal matters more than decibel block. The best plugs create a complete barrier that prevents water from entering the ear canal, which is critical for children with ear tubes or a history of chronic ear infections. Some plugs include a “sound hole” channel to maintain situational awareness, allowing kids to hear coaches or parents while still keeping water out.

In-Depth Reviews
1. WaterDam A-Series Swimming Ear Plugs
The WaterDam A-Series is a thoughtfully engineered flanged earplug that solves two of the biggest headaches for parents: sizing and sealing. It comes in a mixed-size pack covering toddler (10 months-6 years) up through teen/adult, allowing you to find the perfect fit for each individual ear canal. The patented 2-layer waterproof flange design creates a reliable mechanical seal that keeps water out during active swimming, diving, and showering without the putty mess.
What sets the WaterDam apart is its integrated sound hole channel, which lets children hear coaches, parents, and environmental warnings while still preventing water entry. The one-piece construction eliminates the risk of small parts falling into the ear canal, and the silicone withstands high temperatures up to 392°F, so it won’t deform or melt in the ear. Real parents report it stays secure during hour-long swim sessions for kids as young as nine, though several note that achieving the perfect seal requires a deliberate deep insertion that can be tricky at first.
The key trade-off is the learning curve: the plugs must be pushed deep enough to feel a strong suction, which younger children may resist. Once mastered, however, this is the most effective waterproof barrier in the lineup for kids who can handle the insertion technique.
Why it’s great
- Mixed-size pack fits toddlers to teens
- Sound hole allows hearing while swimming
- One-piece solid construction prevents parts breaking off
- Excellent waterproof seal reported in swim tests
Good to know
- Requires deep insertion that may be difficult for young children
- Sound hole reduces, but does not eliminate, water seal risk if inserted shallowly
2. Mack’s Pillow Soft Silicone Earplugs (Adult)
Mack’s Pillow Soft is the gold standard of moldable silicone putty earplugs, combining a verified 22dB NRR with a smooth, tacky texture that conforms to any ear shape without requiring insertion into the ear canal. This sit-on-top design is ideal for children who resist anything going inside their ears, as you simply press the putty over the ear opening. The Official Earplug of USA Swimming, this formula is specifically tested for waterproof protection and doctor-recommended for preventing swimmer’s ear.
Parents appreciate the versatility: the same plug works for swimming, bathing, and sleeping, with the 18-pair pack providing plenty of backup for lost or dirty plugs. The putty stays soft and reusable for up to several days before needing replacement, and the included travel case keeps them clean between uses. The NRR rating withstands pool splash noise, creating a focused swimming experience for kids sensitive to loud environments.
The main downside is the texture attracts hair and lint, which can become sticky and collect debris. Some children find the putty too bulky for small ears, though pinching off a smaller piece solves this. The adult-size portion may feel oversized for toddlers, making it better suited for ages 4 and up.
Why it’s great
- No ear canal insertion needed—sits on outer ear
- Certified 22dB NRR for swim and sleep use
- Versatile for swimming, showering, and sleeping
- 18-pair pack offers high value per use
Good to know
- Putty attracts hair and lint during use
- Portion size may be too large for very small toddlers
3. Mack’s Moldable Silicone Ear Plugs, Kids Size
Mack’s Kids Size is the only product in this lineup specifically portioned for smaller ears, making it the go-to choice for infants, toddlers, and children with very narrow ear canals. These are also widely used by adults with small ear anatomy and by parents who rip a single plug in half for a newborn. The moldable silicone putty covers the ear opening without any deep insertion, which is critical for children with ear tubes, as it prevents any object from entering the canal and causing irritation or tube displacement.
Real-world reviews from parents confirm each pair lasts 20-30 swims when stored properly, and the 6-pack provides months of daily use. The putty becomes less sticky after the first week, which some parents find easier to handle with less hair sticking. Users report it eliminates recurring ear infections over years of use, and the seal is reliable enough for both baths and full swimming sessions. The small size means it fits comfortably behind a swim cap without creating a bulky lump.
The packaging is plain and the product lacks flashy colors or a fun case, which may not appeal to younger children.
Why it’s great
- Specifically portioned for small child ear canals
- Safe for ear tubes—sits on outer ear only
- Each pair lasts 20-30 swims with proper care
- Proven track record preventing recurrent ear infections
Good to know
- Smaller puck means fewer uses per pair than adult version
- Putty still attracts hair and lint after first week
4. Earvolution Putty Buddies Earplugs
Putty Buddies stand out because they were invented by a board-certified ENT doctor with over 40 years of experience, giving them a medical credibility that’s reassuring for parents of children with ear tubes, perforated eardrums, or chronic swimmer’s ear. The moldable silicone is non-toxic, PBA and latex-free, and designed to be used as part of a complete protection system when paired with an Ear Band-It swim headband. The tacky texture is intentionally stickier than generic putty to maintain a secure seal during active play.
The bright purple, teal, and magenta colors plus the cartoon case make the plugs fun for kids, reducing the struggle of getting them to wear protection. Parents report these are the only plugs their children tolerate for extended swimming, and the putty can be reused up to five times before losing tackiness. The sit-on-top design means zero insertion into the canal, making it safe for infants and toddlers when the puck is pinched down to size.
The main limitation is the silicone putty can melt or bond with silicone swim caps, requiring the use of a latex cap or placing the cap carefully to avoid contact. Some users find the tackiness leaves residue on fingers, and the fun colors can become dirty quickly. The 10-pair pack is generous, but the per-pair cost is higher than standard Mack’s.
Why it’s great
- Developed by an ENT doctor with 40+ years experience
- Fun bright colors and cartoon case engage kids
- Safe for ear tubes and perforated eardrums
- Pair with swim headband for total waterproof system
Good to know
- Silicone putty can bond with silicone swim caps
- Higher per-pair cost than budget alternatives
5. Aqua Ears Soft Moldable Earplugs, 18 Pairs
Aqua Ears offers the most affordable per-pair cost in this lineup, delivering 18 pairs of moldable silicone putty that covers the concha (outer ear bowl) without being inserted into the ear canal. Made in Vermont by Cirrus Healthcare Products, these plugs are marketed specifically for swimming and waterproof protection, with a -22dB sound reduction that blocks pool splash noise. The moldable texture is slightly softer and stickier than Mack’s, creating a secure seal that conforms to the ear’s unique shape.
Parents of children with perforated eardrums or extreme ear sensitivity report these are the only plugs their child tolerates, as the soft silicone does not create pressure inside the ear canal. The 18-pair quantity means you can stash pairs in every swim bag, diaper bag, and car without worrying about loss. The putty is reusable for several swim sessions, and the straightforward application—twist into a ball, press over ear opening—requires no special technique.
The biggest drawback is the putty’s stickiness attracts hair and lint more aggressively than other brands, with some users reporting clumps of putty sticking to hair after removal. The lack of a travel case in some packaging means used plugs can collect pocket lint. The seal is effective for swimming, but some parents note the plugs can loosen during vigorous underwater play if not pressed firmly enough against the ear.
Why it’s great
- 18 pairs provide excellent value for high-use families
- Soft, tacky putty works for very sensitive ears
- Safe for children with perforated eardrums
- Easy application—no insertion required
Good to know
- Putty sticks aggressively to hair and clothing
- Seal may loosen during vigorous underwater play
