Foam tips from Sport Pro series that are designed exclusively for the Jaybird Run, Freedom 2, Freedom F5, X2, X3 and BlueBuds X in-ear headphones. They are ideal for workouts and active lifestyles, utilizing isolating body-heat activated memory foam which expands to fill the unique shape of the ear canal, creating a custom, snug fit to dramatically increase in-ear retention. With a perfect ear canal seal, the tips funnel pure sound directly into the ear and block out external noise and environmental distractions. The memory foam keeps earphone in place even in the presence of moisture or sweat and is 30x softer than silicone, reducing earphone irritation and fatigue. The unique acoustically-transparent SweatGuard filter inside the tip further keeps moisture, sweat, and earwax out of the earphone's sound port. This package contains three pairs of medium-sized ear tips (length: 10.67 mm ± 0.65 mm, maximum outside diameter/width: 12.45 mm ± 0.50 mm). Black colour.
