Highest standards of design, durability, comfort and sound quality
DALI IO headphones are a true DALI product, designed and engineered to the same fundamental principles and attention to detail as any other DALI loudspeaker. Every component meets the highest standards of design, durability, comfort, functionality and - most importantly - sound quality. With the DALI IO headphone series, we had a clear goal: they should deliver the best possible sound quality and be extremely comfortable to wear – even when used for hours on end.

Authentic Sound Benefitting from decades of sound design With DALI IO headphones, you benefit from four decades of world-class Hi-Fi loudspeaker design. With the IO-4, our goal was to create the most natural and authentic sound possible and to reproduce music exactly as the artist intended it. We believe we succeeded. 50mm Driver Reproducing the smallest details with crystal clear clarity We understand the importance of a high-performance driver. That's why the IO-4 features a high quality, custom designed driver with a large 50 mm diaphragm and optimizer neodymium magnet system. The result is low distortion, minimal coloration and accurate dynamics throughout the entire frequency range.

Comfort and Design

Ergonomically optimized for a comfortable fit
The stylish IO-4 headphones have been ergonomically optimized and designed with the right amount of adjustability to ensure a comfortable fit. Also, the earpads are made from memory foam that naturally shape to the head for extended use, while creating the best possible seal for a consistent acoustic performance.
