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
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 the S-Logic Natural Surround Sound the usual headphone sound will be moved out of the head in the room around you. The sound is no longer locked in, but appears broad and detached. Directions and distances can be heard and perceived - it 19s just like being in a live concert. For this new technology additional equipment is not required. Take a pair of Ultrasone headphones plus your sound device and you will be ready for the 3-dimensional sound enjoyment!

S-Logic Plus
S-Logic Plus is the enhanced version of the S-Logic System. The specific acoustically designed earcups of the new DJ1 model and its stereo tonal fine tuning of the acoustic reinforcing devices present sophisticated sound and technology. Due to an additional damping, drivers and the bufferboard complement one another with the new spatial sounding unit. The final result is a most neutral sound impression including optimized distance perception of voices and instruments.

Safer Hearing
S-Logic does not only create a Natural Surround Sound. S-Logic allows at the same time a reduction of sound pressure levels by up to 40% (3-4 dB) for the same loudness sensation. This may reduce the risk of hearing damage while ensuring hours of fatigue-free listening. However, Ultrasone generally advises not to listen to music at high volumes to prevent hearing damage.

Designed exclusively for the professional DJ, the DJ1 PRO is the ultimate in style, flexibility and performance. Just like the DJ1, the DJ1 PRO uses our amazingly tough 50mm Mylar driver for lots of volume and bass. Then the DJ1 PRO steps it up by offering detachable cables, speed switch earpads and a carrying case for your headphones and accessories. For the professional DJ, the switchable earpads and cables will save your neck should something happen at a gig. And our patented S-Logic technology will let you spin for hours without worrying about your hearing. Updated for 2008, the DJ1 PRO now features thicker earpads and headband pad, brushed aluminum nameplate on the earcups and a nylon hardcase to protect your headphones on the go.
