Wireless Hi-Fi headphones with a class-leading 60 hour battery life. Designed for maximum comfort with a durable design and a natural, transparent sound performance. Designed and engineered in Denmark.
With DALI's 35+ years of experience in creating high quality loudspeakers, we decided to use our passion and expertise to create the wireless DALI IO-4 - dedicated to today’s music lovers.
With our passion for music reproduction, we were convinced that we could do with headphones what we have done with speakers; provide a better sounding product that delivers music experiences superior to the established competition.
Headphones are essentially a pair of small loudspeakers mounted on your head. They are your personal set of portable hi-fi speakers that enable you to take that authentic DALI sound with you wherever you go.
The DALI IO-4's are intended to be the perfect travel companion for those ‘on the go’ situations.
