Character 
In cooperation with the most famous DJs, Ultrasone developed these outstanding pair of professional DJ headphones. Using a heavy duty 50 mm Mylar driver, the closed-back DJ1 PRO provides the most powerful music output in combination with the most advanced technologies. Equipped with MU-Metal shielding these headphones also meet the needs of DJs considering safer hearing aspects. In addition you will find useful accessories in the DJ1 PRO hardcase: one coiled cord (ca 3m), one coiled cord with volume control and stereo/mono switch and a spare pair of speed-switch earpads. The new designed hardbox will ensure a safe transportation and storage.

ULE-technology & DJ1 PRO design
DJ1 PRO headphones stand for Ultra Low Emission (ULE-technology) with significant benefits for professional users and DJ1 PRO headphones show a specific design. The Ultrasone DJ1 PRO appearance does not only distinguish the professional line but also allows due to more ear anatomy area a higher degree of transparency in combination with the spatial sense and understanding.
To understand what ULE-technology does, you need to know that most headphone drivers produce low-frequency magnetic fields as they convert an electric signal into an acoustical signal you hear as music. In response, Ultrasone developed a special MU Metal shielding (ULE-technology) to reduce the radiation by up to 98% compared to current headphones. The ULE-technology has stood the test of international review and is recommended by technical surveillance organisations. Ultrasone originally developed the ULE-technology for professionals as they do spend half of their lives in headphones. But due to grand requests the ULE-technology has now been integrated in other Ultrasone headphone lines.

S-Logic™ Natural Surround Sound
Through S-Logic™ Natural Surround, the sound moves out of your head and into the room around you. Consequently, the music is no longer confined, but breathing once again, spacious and organic. Direction and distance are more easily perceived ? it’s like being at a live concert (…or in the studio). No additional equipment is necessary. So with just a pair of Ultrasones and your favorite audio device, prepare yourself for genuine 3-dimensional enjoyment!
