Our team first came together as members of the H-Bridges student team from the School of Electrical Engineering at the University of Belgrade. We represented Serbia at the IEEE International Future Energy Challenge 2024, the world’s most prestigious student competition in power electronics and energy efficiency.
The competition task was to design a class D stereo audio amplifier. Our prototype was validated in the finals of the competition at the University of Texas at Austin. Our prototype's performance was remarkable, it had the highest efficiency and the best sound quality.
After being recognized on the global level, we won 2nd place at the national competition for the Best Technological Innovation for 2024.
Encouraged by this success and the unity we have built along the way, we founded H4SOUND to continue our journey towards the market. Our technological base is suitable for use cases from houses of worship, corporate spaces, conference rooms, education and hospitality to transport hubs as an ultimate goal. You will hear our results everywhere around the world. Just listen and don't stop believing!
