The PRO 480i Closed-Back Stereo Headphones from Ultrasone feature a closed earcup design, 40mm Mylar drivers, a frequency range of 20 Hz to 20 kHz, and S-Logic Plus technology. They can be used to provide you with a natural listening experience for music exactly as was intended—without distortions caused by your headphones. The headphones utilize a fixed 3.3' cable with 3.5mm gold-plated plug. A 13.1' extension cable and a gold-plated 3.5mm to 1/4" adapter are included.
S-Logic Plus Technology
This technology combines precision dampening with micro-acoustic reinforcement, allowing driver, buffer-board, and spatial parameters to complement one another in an optimal manner. The redesigned earcups of the headphones and their tonal fine-tuning result in a neutral sound impression with a more vivid perception of voices and instruments.
