Ultrasone AG is a pioneering German headphone manufacturer founded in December 1990 by Florian M. König with the objective of creating advanced headphones emphasizing the professional audio sector. Based near Munich in Tutzing and Wielenbach, Bavaria, the company was born from a 1985 review of the world's best headphones and four years of intensive research focused on improving spatial hearing. Ultrasone revolutionized the audio industry in 1991 with the introduction of their patented S-Logic technology, creating natural surround sound without additional electronic devices for unparalleled spatial perception and three-dimensional listening experiences. The company has developed over 80 patents for innovative technologies including ULE (Ultra Low Emission) technology, which reduces magnetic radiation by up to 98% compared to standard headphones. Operating with the philosophy that 'Made in Germany' represents superior quality, 100% of Ultrasone products are designed and developed by their engineers, with a large portion manufactured in their Bavarian factory. Currently led by CEO Michael Willberg working alongside founder Florian König, Ultrasone celebrated 30 years of high-end hi-fi innovation in 2021 and has established itself as a respected brand serving professional studios, DJs, and discerning consumers across more than 50 countries worldwide through their advanced electro-acoustic engineering.
