Dali iO-4 Bluetooth Over-The-Ear Headphones (Open Box)
AUTHENTIC DALI SOUND
DALI IO is designed and developed in Denmark – build on custom solutions by DALI. The IO’s class-leading custom 50 mm paper fibre cone creates the most natural, transparent and authentic DALI sound. With low distortion and colouration. Reproducing music exactly as the artist intended.
BATTERY LIFE (60 hrs)
The IO-4 provides an incredible class-leading 60 hour battery life, which lets you go for weeks without charging. And should you run out of power, the IO-4 just keeps on going in the passive “Off” mode, when using the supplied Mini Jack cable. Or recharge to 100% in 2.5 hours via a standard USB-C connector.
COMFORT & DURABILITY
The DALI IO ear pads are made from memory foam that shapes to the head for maximum comfort and fit – creating the best possible seal. The pads are covered in soft synthetic leather, chosen for both comfort and durability, and tested to meet real life challenges.
CONNECTIVITY
For high wireless audio performance, the DALI IO supports Bluetooth AptX, AptX HD and Apple AAC. But for the highest possible quality, DALI IO includes a USB-C connector, which supports digital audio streaming from Windows or Mac. The IO also incorporates a traditional wired analogue Mini Jack.
DALI IO
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.
