The Dali IO-12 over-ear headphones in dark chocolate deliver authentic HiFi sound quality through advanced acoustic technology. These headphones integrate patented Soft Magnetic Compound driver material, low-loss rubber surrounds, rigid paper fiber cones, and resonance-dampening housings for lossless audio playback with exceptional clarity and dynamic range. As the world's first headphones featuring SMC magnet technology, they significantly reduce harmonic distortion for crystal-clear sound with minimal coloration. The IO-12 headphones offer versatile connectivity options, including Bluetooth aptX Adaptive for high-quality wireless streaming and wired connections for traditional audio systems. Advanced active noise cancellation technology with three adjustable modes creates immersive listening experiences by suppressing low-frequency disturbances while maintaining audio fidelity. A highly developed lithium-ion battery allows for up to 35 hours of uninterrupted playback with noise cancellation activated and takes about 2 hours for a full charge. Battery status indicators and voice prompts inform users of remaining power. Two sound modes enable customization between reference-quality HiFi playback and enhanced bass reproduction for different listening preferences. The over-ear design with a black finish combines high-quality materials and construction for long-lasting listening comfort. These headphones measure approximately 20 cm in height, 16 cm in width, and 8 cm in depth when folded, weighing 320 grams. They represent a successor model in Dali's audio equipment range, preserving the acoustic principles of their full-format speaker systems while providing portable, high-quality listening experiences for home and mobile use.
