Start Your Day Without “Water Panic”

For many hearing aid users, sweat, rain, or even a child’s playful splash can raise the same worry: “Did I just damage my device?” At Yeasound, we understand that concern. That’s why we designed a waterproof solution you can truly rely on.

1、Outer Defense: Yeasound hearing aids are treated with an advanced Nano Coating—an invisible “rain jacket” that makes sweat, rain, and everyday spills roll right off. We also reduced every gap to less than 0.2 mm (thinner than a strand of hair) to minimize the chance of water seeping in.

2、Inner Defense: The real threat is often hidden moisture and the corrosive effects of sweat, which can gradually damage delicate parts over time. To stop it, we use aerospace-grade Parylene Coating on the internal components—chips, microphones, and even fine wires. This molecular-level seal blocks corrosion and keeps your hearing aid working reliably for years.

This is not just a claim. It’s the result of 18 months of R&D and 57 rounds of seal testing. The RIC800 is certified with an IPX8 waterproof rating, proven to withstand submersion at 1 meter for 1 full week. At every stage, our goal was simple: to ensure your hearing aid works when you need it most.
