VOLUME VAULTS™ Turn Down The Volume, Not The Fun. Noise reducing checker ear protection for toddlers/kids. Volume Vaults™ are Little Trouble’s exclusive hearing protection — designed for high-energy events, busy environments, and everyday focus moments. Whether it’s monster trucks, motocross, air shows, fireworks, concerts, or just dialing in for homework time, these are made to protect their ears without slowing them down. Third-party tested and rated NRR 21, Volume Vaults™ reduce noise by 21 decibels when worn correctly, helping protect young ears from harmful sound levels while still allowing them to sit front cheering on their favorite racers. The level of noise reduction may vary depending on proper fit and consistent use. Designed with a gloss black and white checker ear cover, super soft and supportive PU leather ear cushions, and a woven, padded adjustable headband, they’re comfortable enough to wear for hours.
