Electro-Voice (EV) designs and manufactures professional loudspeakers, microphones, and sound reinforcement systems for live performance, installed sound, broadcasting, and commercial AV. EV is one of the few brands in the industry that designs all loudspeaker components (cabinets, waveguides, transducers) in-house, ensuring consistent quality from individual speakers to complete networked systems. Over 90 years of history have fostered milestone innovations such as Variable D microphone technology, Constant Directivity (CD) Horn technology, and the broadcast standard microphone RE20.

Electro-Voice was founded in 1927 in South Bend, Indiana, USA. In July 2025, following the spin-off of Bosch's Communications division, it became part of the newly formed KEENFINITY Group (sister brands include Dynacord, RTS, and Telex), with over 4,200 employees globally and a group revenue of approximately 1 billion euros for the 2024 fiscal year. EV primarily serves professional audio engineers, touring production companies, system integrators, and the broadcast market. In 1963, it was awarded an Oscar for the 642 Cardiline shotgun microphone, marking the first time an audio product received this honor.
