Go with Music

With over 30 years of experience creating high quality loudspeakers, Danish brand DALI decided to use their passion and expertise to create a headphone dedicated to todays music lovers. The DALI IO-4 are wireless, battery rechargeable hi-fi headphones that are over-ear (circumaural), with a closed-back design, engineered to offer extremely high quality sound reproduction. With an incredible battery life of up to 60 hours per charge, the IO-4 are the perfect travel companion. They have been ergonomically optimised and designed with the right amount of adjustability to ensure a comfortable fit to any user and are light in weight without compromising quality or durability. The ear pads of the DALI IO-4 are made from memory foam that naturally shapes to the head, therefore creating the best possible seal, which is important for a consistent acoustic performance. The pads are covered in soft synthetic leather, chosen for maximum comfort and durability.

Authentic DALI sound

DALI's custom-made 50mm drivers deliver an exceptionally life-like performance. Listen in high definition over Bluetooth or USB and experience your favourite music as you've never heard it. The DALI IO-4 headphones have been specifically designed to be as intuitive to operate as possible. No need to read the manual, just switch them on, connect to a source and start listening to the music.
