The E6OW5L1SR is the world’s favorite earset. The low-profile E6 provides natural sound with exceptional isolation from noise and feedback. An ultra-miniature electret condenser element is held close to the mouth by a thin boom and comfortable earpad. Three sensitivity options cover general speaking applications through extremely powerful vocals. Four colors allow you to match the E6 to your skin tone for minimum visibility. The boom adjusts for a custom fit and is available in our classic springy style, the extremely flexible "i" style, or the Flex style providing a soft boom in front and a springy ear section.
