ENGINEERED IN DENMARK

Sound, design, durability & comfort

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.

50 MM DRIVER

Precise sound 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 optimised neodymium magnet system. The result is low distortion, minimal colouration and accurate dynamics throughout the entire frequency range.

COMFORT AND DESIGN

Optimised for the most comfortable fit

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.

EXTENDED BATTERY LIFE

Up to 60 hours playback

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.

AUTHENTIC DALI SOUND

DALI IO headphones are built on a class-leading 50 mm paper fibre cone for the most natural, transparent and authentic DALI sound.

COMFORT & DURABILITY

DALI IO ear pads are made from memory foam that shapes to the head for maximum comfort, fit and seal.

BATTERY LIFE(60hrs)

The IO-4 offers a class-leading 60 hour battery life that lets you go for weeks between charges – and recharges in just 2.5 hours.

CONNECTIVITY

DALI IO headphones support Bluetooth® aptX, aptX HD and Apple AAC. For best results, use the included USB-C or mini-jack connectors.
