Watersafe+ is rated to 3m depth and uses a dual-flange silicone design specifically built for the turbulence of real water sports. The inner flange creates a primary seal; the outer flange holds it in place under pressure. Tested through duck-dives, wipeouts, and flip turns. A single-flange foam plug relies on friction alone — it was not designed for this environment.

The dual-flange design grips the ear canal at two points rather than one, which is what keeps them secure when your head is being thrown around by a wave. Most surfers who have tried disposable foam plugs report they fall out on the first duck-dive. Watersafe+ is specifically engineered to avoid that. If they do not stay in, our AR KI TECH fit service will find your exact size before we ship your next pair.

Yes. The medical-grade silicone used in Watersafe+ is chemically inert and unaffected by salt, chlorine, or sunscreen. Rinse with fresh water after each session and they will maintain their shape and seal for up to 100 uses. No degradation, no discolouration, no smell.

Watersafe+ carries an independently certified 24 dB SNR rating, tested by PZT GmbH (EU Notified Body No. 1974) across over 1,700 individual measurements. This is the same rating standard used for professional hearing protection. For reference, a breaking wave can reach 85 to 95 dB — the 24 dB reduction brings that into a safe listening range during a long session.

Foam earplugs achieve their noise reduction by expanding to fill the canal irregularly, which also means they seal inconsistently, especially in a wet environment. Medical-grade silicone creates a shaped, repeatable seal against the canal walls every single time. For water sports, silicone also offers something foam cannot: it maintains its seal when wet, compressed, or under pressure. Foam absorbs water and loses its effectiveness quickly.

Watersafe+ comes in two sizes (standard and small). If you are unsure, our AR KI TECH service removes the guesswork entirely. Upload two photos of your ears with your phone, and our AI analyses your exact ear canal geometry and ships the correct size directly to you. This is why our return rate is 3% compared to the industry average of 15 to 20%.

Yes. Watersafe+ is specifically recommended for anyone who has had grommet surgery or has pressure-equalising tubes in place. The waterproof seal prevents water from reaching the eardrum, which is exactly what post-operative ears need. Always confirm with your ENT specialist before returning to the water after surgery, but Watersafe+ is the preferred earplug type for this situation.

Buy Watersafe+, use them for up to 40 days in real conditions — surf sessions, pool training, open-water swims, all of it. If they do not perform as described, contact us for a full refund. No forms, no arguing, no questions about how many times you wore them. We offer this because we are confident the product works. Over 10,000 verified reviews suggest it does.

Disposable foam plugs are designed for one purpose: blocking noise in dry conditions. They have no meaningful waterproof rating, they absorb water, they lose their seal when wet, and they are not designed to handle the pressure of diving or heavy surf. Watersafe+ is engineered from the ground up for water ingress prevention. After up to 100 uses, the cost per session works out to around 27p. That is considerably less than restocking foam plugs every few swims, and well short of the cost of treating a recurring ear infection or surgical exostosis removal.

AR KI TECH is Bollsen’s AI-assisted fit service. You upload two photos of your ears using your phone; the AI analyses your canal shape and recommends the correct earplug size with precision that an in-store fitting cannot match. The result: a 3% return rate versus the industry average of 15 to 20%. For water sports, where fit is everything (a loose plug in a wipeout is useless), getting the right size before your first session is worth the extra step.
