Dali iO-4 Iron Black

The DALI Sound Heritage

The Dali iO-4 Iron Black headphones represent the culmination of the Danish brand's 35-year expertise in high-end loudspeaker design. Engineered with the same passion and acoustic principles as DALI’s flagship speakers, these headphones deliver a listening experience that reproduces music exactly as the artist intended. At their core lies a custom-designed 50mm driver with a paper fibre cone, ensuring a natural, transparent, and authentic sound, free from coloration and distortion.

Class-Leading Battery Life

With an incredible battery life of up to 60 hours, the Dali iO-4 sets a new benchmark in its category, allowing you to enjoy your favorite music for weeks without needing a charge. Even if the battery runs dry, the music never stops, as the headphones support passive operation via the included mini-jack cable. Charging is equally efficient, reaching a full cycle in just 2.5 hours via the integrated USB-C port.

Ergonomics and Premium Build

Comfort is a priority for DALI, which is why the iO-4 features memory foam ear pads that adapt perfectly to the shape of your head. This design not only ensures fatigue-free use for hours but also creates the ideal seal for optimal acoustic performance. Wrapped in durable synthetic leather, the headphones are built to withstand daily use while maintaining a sleek, sophisticated aesthetic that fits any environment.

Advanced Connectivity

The Dali iO-4 supports Bluetooth aptX, aptX HD, and Apple AAC protocols for high-fidelity wireless performance. For those seeking the highest possible quality, the USB-C port allows for direct digital audio streaming from a PC or Mac. Whether you are at home, in the office, or on the move, the iO-4 guarantees a stable, high-resolution audio experience that will satisfy even the most demanding audiophile.
