For best protection ear cushions should seal firmly against the head. Anything that interferes with the seal such as long hair, thick or poorly fitting eyeglass temples, pencils, or caps, will lessen the protection. Do not bend and reshape the headband as this will cause a loose fit and sound leakage.
