With DALIs 35+ years of experience in creating high quality loudspeakers they decided to use their passion and expertise to create the wireless DALI IO-4 - dedicated to todays music lovers. With their passion for music reproduction Dali were convinced that they could do with headphones what they 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-4s are intended to be the perfect travel companion for those on the go situations.
