WaterSafe vs WaterSafe Pro: Which Swimming Earplug Offers Better Water Protection?

Swimming earplugs are a simple but essential piece of kit whether you swim laps weekly or just enjoy a dip on holiday. They help keep water out of your ear canal, reducing the risk of swimmer’s ear (otitis externa) and protecting your hearing from the pressure changes that can occur underwater. Alpine offers two popular options for swimmers: the WaterSafe and the WaterSafe Pro. Both are designed to seal the ear against water, but they differ in materials, fit, and intended use. This comparison will help you pick the pair that matches your swimming habits, comfort needs, and budget.

Before diving into the details, it’s helpful to know that both models use a waterproof filter system that lets air pass while blocking water. That means you won’t feel the uncomfortable pressure buildup you get with solid plugs. The key difference lies in how they fit your ear and how much customisation you want. Below we break down the design, water protection level, durability, and ideal user scenarios for the WaterSafe and WaterSafe Pro.

Design and Fit: Universal vs Custom-Fit

The standard WaterSafe earplugs come in a one-size-fits-most design with a soft, translucent silicone stem and a small flange that sits at the ear canal entrance. They are lightweight and easy to insert, making them a great starter pair for casual swimmers. Because they don’t go deep into the ear canal, most people find them comfortable even for longer sessions in the pool.

The WaterSafe Pro takes a different approach. It uses a hypoallergenic, moldable silicone tip that you shape to your own ear canal before use. This gives a truly personalised seal that stays put during vigorous swimming, flip turns, or open-water conditions. The moldable material hardens slightly after shaping but remains flexible enough for reuse. If you’ve struggled with standard plugs working loose, the Pro’s custom fit is a clear upgrade.

Practical tip: When trying the WaterSafe Pro, roll the moldable tip into a smooth ball, insert it gently, then hold still for 60 seconds to let it set. This ensures a snug, watertight seal.

• WaterSafe: universal flange design, easy in/out, minimal intrusion into ear canal.
• WaterSafe Pro: moldable custom-fit tip, deeper seal, ideal for irregular ear shapes.
• Both come with a small carry case, but only the Pro includes a second pair of moldable tips for replacement.

Water Protection and Noise Reduction

Both earplugs are tested to block water effectively, but the level of protection differs. The WaterSafe provides a solid seal for recreational swimming and shallow dives. Its filter system prevents water from entering while equalising pressure, so you won’t feel that annoying suction when you surface. The noise reduction is modest – about 10–16 dB – which is enough to take the edge off splashing and echo in indoor pools without making you feel isolated. This makes it a good choice for swim lessons, family swims, or people who want to hear instructions clearly.

The WaterSafe Pro offers a higher level of water protection thanks to its custom-fit seal and a more advanced filter. It blocks water more effectively during deep diving, surf sessions, or high-velocity water sports. The noise reduction is also greater, around 16–22 dB, which provides more tranquility underwater and reduces the distraction of engine noise or waves. However, because the seal is tighter, you may find it harder to hear conversations poolside – a trade-off worth noting if you swim in groups or coach others.

• WaterSafe: water protection for recreational swimming, shallow depths, and pool use.
• WaterSafe Pro: enhanced water seal for deep diving, open water, and surf; higher noise reduction.
• Neither model is submersible beyond 2–3 metres – for scuba diving, use specialised plugs.

Durability, Maintenance, and Reusability

The standard WaterSafe is designed as a reusable earplug that lasts for months with proper care. The silicone flanges are durable but can wear out over time, especially if you frequently remove them roughly or expose them to chlorine for long periods. Cleaning is simple: rinse with fresh water after each swim and let air dry. For deeper hygiene, a few spritzes of Earplug Cleaning Spray can help remove bacteria and extend the life of your plugs.

The WaterSafe Pro is built to be more robust. The moldable tips can be reused multiple times (typically months, depending on earwax and cleaning habits), and the plug body is made from a firmer medical-grade silicone. An extra set of tips is included, effectively doubling the lifespan. The replaceable tips mean you don’t have to discard the whole plug when the seal weakens – just swap the tips. This makes the Pro a more economical choice in the long run for frequent swimmers, despite the higher upfront cost.

Practical tip: Always store both models in their ventilated case to prevent moisture buildup. Avoid leaving them in direct sunlight or a hot car, as heat can distort the silicone.

• WaterSafe: good for 3–6 months of regular use; easy to clean with water.
• WaterSafe Pro: lasts 6–12 months with tip replacement; more resistant to chlorine and UV.
• Both benefit from occasional use of Earplug Cleaning Spray for odour and germ control.

Best Use Cases: Which Swimmer Should Buy Which?

If you swim once or twice a week in a chlorinated pool, stick to water aerobics, or take your kids for lessons, the Alpine WaterSafe is the sensible choice. It’s affordable, easy to put in, and gives enough protection to keep your ears dry without muffling conversation. Parents often prefer it because they can still hear their children splashing or calling out. The universal fit suits most adults and teenagers, though kids with smaller ear canals may need the kids-specific version (not covered here).

The WaterSafe Pro is aimed at more dedicated swimmers: lap swimmers doing 2km+ sessions, triathletes training in open water, surfers, and anyone who has had trouble with plugs falling out. The custom fit provides peace of mind that water won’t sneak in during tumble turns or wave impact. If you’ve tried standard earplugs and found them leaky or uncomfortable after 30 minutes, the Pro’s moldable design is worth the investment. It’s also the better choice for people with unusually shaped ear canals or prior ear infections who need a reliable seal.

• WaterSafe: best for casual pool swimmers, families, and water fitness classes.
• WaterSafe Pro: best for frequent lap swimmers, open-water athletes, and surfers.
• Both are not suitable for scuba diving or deep freediving beyond 3 metres.

Choosing between the WaterSafe and WaterSafe Pro comes down to how often you swim and how much customisation you want. For regular pool sessions and an easy, comfortable fit, the standard WaterSafe does the job reliably at a lower price. If you’re a serious swimmer who needs a watertight seal for long hours in the water or challenging conditions, the WaterSafe Pro’s moldable tips and higher protection level make it the better long-term companion. Whichever you pick, pair your earplugs with a good drying routine and an occasional clean using Earplug Cleaning Spray to keep them performing well throughout the season.
