9 out of 10 earplugs on the market work the same way: a single foam or silicone barrier that blocks sound unevenly, cutting highs first, then mids, then bass, until the mix collapses into mud. That's the moment people pull them out. It's also the moment real damage starts.
Hears runs on NEW 2nd Eardrum Technology: a precision-tuned membrane engineered to intercept harmful volume the same way your natural eardrum processes sound, reducing every frequency equally instead of cutting some and letting others through.
At 110dB, a typical festival main stage, that brings your actual exposure down to roughly the equivalent of a busy café.
Same music. Same energy. Just re-engineered so your ears can survive the whole set, not just the opener.
