Ultrasone Pro 2500

You prefer open-back headphones? Using the same stiff titanium-plated drivers as PRO 750, the Ultrasone PRO 2500 model provides due to its open-back design the most airy sound within the complete PRO line. Accuracy and the finest sound reproduction is guaranteed for everybody who does not wish a closed-back system.

ULE-technology & PRO design
PRO headphones stand for Ultra Low Emission (ULE-technology) with significant benefits for professional users and PRO headphones show a specific design. The 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!

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.
