DALI elevates the headphone market with the introduction of the DALI IO4 wireless bluetooth headphones and class leading 60 hour battery life. Authentic DALI sound, comfort and classic Nordic design are the hallmarks of this high quality Danish wireless bluetooth headphone.

The DALI IO4 are wireless, battery rechargeable hi-fi headphones. They are over-ear (circumaural), closed-back designs, engineered to offer extremely high quality sound reproduction. The IO4 is available in two colour finishes: Iron Black and Caramel White.

Today, we spend more and more time on the go, whether it be commuting to work or traveling for business and pleasure. All of this time we spend ‘on the go’ can also become time to spend doing what we enjoy, whether that being listening to our favourite music or watching a great film.

The DALI IO headphones are intended to be the perfect travel companion for those ‘on the go’ situations, delivering the ultimate audio performance. The flexible headband and swivel ensure they are as comfortable around your neck as they are on your head so you can travel with ease.


Custom-made 50mm drivers that 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 before.


Luxuriate in music without limits. DALI IO is built for extended listening with a comfortable, durable design and a natural, transparent sound that never tires. Every one of us is unique; we all have different sized heads and ears. DALI IO headphones have been ergonomically optimised to ensure they comfortably fit as many people as possible. This required numerous prototypes, and analysis of different combinations of ear pads, headband curves and ear-cup angles. The result is a design with the right amount of adjustability required to provide a natural fit to anyone.


As well as wireless Bluetooth connection, the DALI IO also supports wired connections through the USB-C and the 3.5mm mini jack input.


Go for days without recharging. Our advanced lithium-ion battery delivers peerless playback on a single charge. Up to 60 hours playtime.


The built-in microphones in the DALI IO allow you to use the headphones for hands-free telephone calls and voice control.
