Developed with Rod Morgenstein, these isolation headphones were designed to protect musicians from the high sound levels associated with their instruments. Prolonged exposure to these excessive levels of noise can have traumatic and lasting effects, including hearing fatigue, tinnitus and permanent hearing loss. These specialty headphones drastically reduce levels of external sound reaching a musician's ears, offering valuable protection from potential damage. From the start caring for kids' hearing is important! These non-electronic headphones are specially sized for children and reduce overall noise levels by 22 decibels.
