Doc's Proplugs are specially moulded to fit the ear, they are comfortable to wear and are available in 8 different sizes to ensure a perfect fit. Vented Proplugs provide around 20dB sound reduction, and are available with or without a leash. Non-vented proplugs offer even more sound reduction (30dB) and are available in blue and pink. They are made from hypoallergenic Kraton and fit snugly into the auricle of the ear, rather than the ear canal, and therefore do not compact earwax. Used by musicians, road crew, clubbers, recording engineers and music listeners worldwide.
