Why "Safe Listening" Kids Headphones? Hearing is precious and needs to be protected from a young age as even short-term exposure to loud volumes can cause permanent hearing loss in children. KidJamz child-safe headphones use volume-limiting technology to ensure that the audio your kids are streaming from their devices is safe so you don’t have to constantly monitor how they listen to movies, music, and games. KidJamz Volume-Limiting Technology While regular headphones and earphones can easily exceed safe volumes by 50% or more, KidJamz utilizes a proprietary volume limiter built into the structure of the speakers to maintain the sound pressure level (SPL) below a physician-recommended 85dB*, keeping young ears safe and helping create lifelong good listening habits. *85dB limit is based on an industry-standard 1mW audio output of a typical portable audio device. Volume Limiter switch A concealed switch allows parents to disable the volume limiter so that KidJamz can be used in noisy environments. This switch is protected against accidental activation and alternates between volume-limited (85dB) and unlimited modes, granting parents full control of the listening experience. Designed with Kids in Mind The best kids’ headphone is the one kids will want to use, so we set out to make KidJamz as lightweight, safe, and frustration-free as possible. The adjustable headband and vinyl earpad cushions provide a comfortable and secure fit for boys and girls ages 4-12 while the reinforced cable is tough and tangle-resistant. Durable Construction Engineered with fewer moving parts, the KidJamz provide outstanding durability thanks to robust BPA-free plastics, a tangle-resistant cable with reinforced connectors, and a flexible headband that can be bent and twisted in any direction without breaking. MEE Signature Sound We believe creating good listening habits early starts with great sound quality, and the KidJamz are tuned to deliver high-quality stereo sound that is crisp and clear, yet smooth and non-fatiguing.
