This is what every parent asks first. The honest answer: Kidz+ is far more likely to stay in than any earplug a child finds uncomfortable. The medical-grade silicone adapts to your child’s ear canal with body heat, forming a soft seal that doesn’t pressure or irritate. Because there’s no hard housing, no cable, and no bulky outer shell, most children stop noticing them within the first few minutes. Parents consistently report that children who rejected earmuffs or foam plugs accepted Kidz+ without resistance. If they do pull them out, it’s almost always a fit issue — use the AR KI Tech measurement to get the exact size for their ear.

Yes. Kidz+ is made from medical-grade silicone that is BPA, PVC, latex and cadmium free — the same material standard used in surgical instruments. The design was specifically developed for children’s ear canals aged 3 to 12 and has been independently tested by German laboratories to ISO 4869. For children under 3, we recommend earmuffs rather than in-ear protection.

Yes. Kidz+ features a waterproof 2-lamella seal that locks against the ear canal wall — including during freestyle, backstroke and diving. It is specifically recommended for children with grommets (ear tubes) or a history of swimmer’s ear. For the most reliable fit in very small or large ear canals, we recommend our AR KI Tech ear measurement.

Yes — and that is intentional. Kidz+ uses high-fidelity filtering that reduces harmful noise levels by an average of 24 dB while keeping speech, voices and instructions clearly audible. Your child will hear their swim instructor, their teacher and you calling them. What gets blocked is the noise that damages: loud music, crowd noise, machinery and traffic.

Yes, and this is one of the most common reasons parents choose Kidz+. For sensory-sensitive children, the biggest problem with earmuffs is that they are visible, bulky, and stigmatising — children refuse them or classmates comment. Kidz+ sits invisibly in the ear. It filters the harsh edge off loud environments while keeping speech clear, which means your child stays connected to the people around them rather than being shut out completely. Parents of autistic and ADHD children consistently report a meaningful reduction in overstimulation, meltdowns and sensory fatigue.

Yes. The waterproof 2-lamella seal is specifically trusted by parents and recommended by ENT specialists for children with tympanostomy tubes (grommets) or perforated eardrums during bathing and swimming. The seal keeps water fully out of the ear canal, eliminating the infection risk that water entry creates. Always confirm with your child’s ENT or GP first, particularly in the early stages after surgery.

Gently pull the top of your child’s outer ear upward and back to open the ear canal. Insert the clean earplugs with a gentle twisting motion until the outer lamella sits flush with the entrance of the ear canal. Do not push them too deep. The removal tab makes it easy to take them out — your child can learn to do this themselves within a few uses.

Each pair is reusable up to 100 times. With daily use, that’s roughly 3 to 4 months from a single pair. Medical-grade silicone retains its shape and resists dirt far better than foam or putty, and the fit actually improves slightly over time as the silicone adapts. Clean after each use with a damp cloth and mild soap, and store in the included aluminium case.
