At BOLLSEN, we know: Kids do what they want. That’s why they need hearing protection that keeps up with their pace: romping around the playground, jumping off the pool edge, falling tired into their seat on the airplane. That’s why we developed Kidz+ as an all-rounder for the diverse daily adventures of our little ones. Did you know that children perceive many sounds as louder than adults do? There are a couple of reasons for this: firstly, minors’ inner ears are not yet fully developed. The sensory cells in their ears are more sensitive to sound stimuli. Secondly, their ear canals are shorter and narrower: sound waves hit the eardrum faster and more intensely. That’s why it’s important to protect their hearing – to prevent hearing loss, tinnitus, or other permanent damage. That’s why we designed Kidz+ specifically for sensitive children’s ears.

2-lamellar design against noise

Independent laboratories in Germany have tested our ear protectors. The result: Kidz+ reduces noise levels by an average of 24 decibels, effectively lowering many unpleasant to potentially harmful noise environments to a safe level.

Kidz+ filter technology for clear instructions

The teacher calls, but your child keeps swimming? Not anymore. Kidz+’s filter technology ensures this: it dampens low, steady frequencies like traffic noise – while letting high frequencies like the morning alarm or conversations through.

Medical-grade silicone adapts to the ear canal

Children are demanding. A bothersome plug? Easily pulled out of the ear. That’s why Kidz+ is exceptionally soft: the medical-grade silicone molds to the shape of the ear canal, providing a comfortable fit that many children quickly forget they’re wearing.

Secure fit in every situation

Kidz+ fits snugly in the ear, disappearing completely. Perfect for daring jumps from the three-meter diving board, playing vigorously on the playground, or napping as a side sleeper. Ready to re-enter the noisy world? Simply pull them out by the tab.

Hearing protection with a 40-day money-back guarantee

At BOLLSEN, you buy without risk: Let your little ones test the new earplugs for 40 days – and then decide if you want to keep them. They don’t help? Just send the earplugs back to us. We’ll refund the full purchase price.

Sustainable sound protection for children’s ears

Let’s leave a livable planet for the next generation: Our Kidz+ reduce single-use waste, plastic pollution, and CO₂ emissions – while being practical companions through everyday life.

Reusable 100 times

Kidz+ are made of medical-grade silicone. It’s more resistant to dirt than foam and lasts three to four months even with daily use. Plus, since the material retains its shape, it gets more comfortable every day.

Quickly cleanable

Earwax? No problem. Simply clean the earplugs with a damp cloth and a bit of soap. While on the go, protect them in the provided aluminum case from contamination – ensuring the hearing protection is always within reach.

Free from allergens

Many children have allergic reactions to various substances – sometimes even without their parents knowing. That’s why we avoid typical allergens like BPA, PVC, plasticizers, latex, and cadmium right from the start.

CO2-free by 2025

We aim to achieve carbon neutrality in our production by the year 2025.

Plastic-free

Instead of using plastic, we opt for natural silicone, which reduces single-use waste.

Short transportation routes

We produce in the EU, saving 4900 kilograms of CO₂ annually.

The soft natural silicone molds to the shape of your ear canal from the first wear, filling the entire ear canal.  Our standard-size ear protection fits most people with average-sized ear canals.
