The 'Baby Blue' Etymotic eartips for 'smaller' ears now come in frosty grey! They still use a smaller dimension plus a softer and much more pliable grade of silicon rubber that's designed to get into the nooks & crannies of a smaller-sized ear canal easily. The plush wearing comfort and excellent isolation properties of these eartip sleeves is a big plus too. The overall dimension of the Small Frost Rubber Tips is about half the size compared to the standard 'white' silicon 3-flange Etymotic eartips. Package includes 10 tips (5 pairs). Will fit the ER-4, ER6i, HF, MC, and EK models. NOTE: Eartips are NOT returnable due to hygiene/health concerns.
