Shure E3 Sound Isolating Earphones deliver the incredible sound and performance that earbuds and other headphones simply can’t. Sound isolating and unobtrusive, they’re designed specifically for use with Shure PSM systems.
Along with their high-fidelity, full-bandwidth transducers, the ergonomic design of these stereo earphones allows them to rest comfortably in the ear, providing a tight seal for sound isolation and a snug, secure fit. They can be used with a variety of foam, flex, or triple flange accessory sleeves to get a personal fit tailored to your ears. The universal 3.5mm (1/8″) plug connects to Shure’s PSM body pack receivers, as well as many other personal audio applications where high fidelity is a must.
