ER20 Preserve Sound Quality

The human ear overloads at high sound levels, making it difficult or impossible to distinguish speech or a musical blend.

ER20 Prevent Ringing in the Ears

Ringing in the ears (tinnitus) and temporary hearing loss can occur from a single concert, sporting event or sudden load noise like a gunshot or firework. Even if a temporary hearing loss recovers over a period of hours or days, there is a risk that repeated exposure to loud noise could result in permanent damage or hearing loss.
