Foam tips for in-ear headphones from Audio Pro series that are compatible with most ear buds – they fit on sound port nozzles with 4.85mm - 6.25mm diameter. They have spherical shape and are made from premium body-heat activated memory foam which adapts to ear canal to provide a perfect seal and snug fit to keep the ear buds in place while blocking external sound, and therefore provide a superior audio experience with enhanced bass. The super-soft memory foam is also 30x softer than silicone and reduces earphone irritation and fatigue. This package contains three pairs of standard-sized tips. The acoustically-transparent WaxGuard filter inside the tip further keeps earwax and debris out of the earphone's sound port. The package contains free pairs of medium-sized tips. Black colour.
