Spreading clear sound around the world

H4SOUND grew out of the student team H-Bridges 2024 from the School of Electrical Engineering, University of Belgrade. At the International Future Energy Challenge, the world's leading power electronics competition, we built a Class-D audio amplifier and won 4th place globally. Inspired by this success, we founded H4SOUND to continue the journey beyond the competition.
H4SOUND develops Class D audio amplifiers designed to set new standards in power efficiency and audio performance.

"Spreading clear
sound around the
world"

Our mission is to efficiently spread clear sound around the world with the intention of transforming and modernizing traditional PA and commercial audio sound systems through digitalization. We are going to bring academical achievements combined with creativeness and greatness to the market in form of a sticky product which will let people feel the fresh smell of the clear sound. One day, H4SOUND will become a globally recognized synonym for clear sound.
