High‑Fidelity Wireless Sound
The Dali IO‑4 wireless headphones deliver rich, detailed audio that makes every track feel alive. Designed with DALI’s acoustic expertise, they offer balanced sound across the frequency range—crisp highs, natural mids, and satisfying bass—so your music sounds true to the original recording. Whether you’re enjoying playlists, podcasts, or movies, the IO‑4 brings clarity and depth to every listening session.
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 optimised neodymium magnet system. The result is low distortion, minimal colouration and accurate dynamics throughout the entire frequency range.
Comfortable Design for All‑Day Wear
Built for daily use, the Dali IO‑4 combines plush ear cushions with a lightweight headband for lasting comfort. Their ergonomic design ensures a secure, snug fit without pressure fatigue, making them perfect for long flights, commutes, or relaxed weekends at home. Stylish finishes and premium materials add an elegant touch to your everyday audio gear.
The stylish IO-4 headphones have been ergonomically optimised 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.
Seamless Connectivity and Smart Control
With advanced Bluetooth technology, the Dali IO‑4 make wireless listening effortless. Quick pairing with your smartphone or tablet and intuitive onboard controls let you manage music, calls, and volume without touching your device. Long battery life ensures you stay connected and entertained throughout the day, combining convenience with quality sound.
Our advanced lithium-ion battery lets you listen to your favourite music nonstop for up to an incredible 60 hours. With battery level LEDs and voice prompt, you always know how much charge is left. And if your IO-4 runs dry, continue in passive 'off' mode to keep the music alive.
