Earos

EAROS makes high-fidelity acoustic filters that protect hearing while preserving sound quality, as an affordable alternative to foam earplugs and expensive custom musician plugs. Unlike earplugs that block sound, EAROS filters let frequencies pass through while reducing volume to safer levels for concerts, nightlife, sports, and other loud environments. Founder Ronnie Madra, a DJ, event producer, and nightclub co-founder who developed tinnitus and hearing loss after decades in loud venues, created the brand to give others the hearing-protection guidance he wished he had.
