The newly redesigned Jazz Band reduces band pressure by 50% and has achieved a higher NRR rating of 25dB. The Jazz Band is cooler to use than earmuffs, provides more cost effective protection than many available earmuffs, and the lightweight design is more comfortable. The handy breakaway neck cord, included with every Jazz Band allows the Jazz Band to hang conveniently around the user's neck when not in use. It will not interfere with eyewear. The soft and hard material combination dampens vibration. A pair of replacement pods is included in each package. 100% PVC-Free.
