The Etymotic Research hf5 headphones are a set of in-ears designed for portability. In typical Etymotic style, they have incredibly small ear buds with a splash of color. Our review unit was cobalt.
If the default sleeves pictured above just aren't doing it for you, don't fret: the hf5s come with three additional sleeves. From top to bottom, the hf5s' sleeve understudies are: foam, a larger triple-flange, and soft plastic.
The headphones end in the standard 1.
