ULTRASONE Signature Master MKII headphones

From a true music lover to those who love music as the best way to connect people. The idea for ULTRASONE was born from a review of the world’s best headphones in 1985. Great products – but far from perfect. Improving spatial hearing was a clear goal for creating better headphones. After four years of intensive research, the first patent was applied for and a year later ULTRASONE was founded. In 1991, the first ULTRASONE headphones with the well-known S-Logic technology were presented to the public.
