We listened carefully during the design of the Signature STUDIO and that went far beyond the tonal balance. Musicians and sound engineers from around the world contributed countless ideas during the development of this new Signature model. They encouraged us to question the status quo and develop a set of ULTRASONE studio headphones with the resolution, robustness and high shielding to impress even the most demanding of users. The choice of driver ensures that audio material can be assessed properly with the greatest range of audio players. From an Apple MacBook Pro audio output through to a professional headphone amp the Signature STUDIO provides precision playback for all audio sources.
