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.
With DALI IO headphones, users benefit from more than 35 years of experience designing some of the finest hi-fi loudspeakers in the world. The DALI IO-4's are designed and engineered by the same team and to the same basic principles as any other DALI loudspeaker. The aim is to create the most natural and authentic sound possible - and to reproduce music exactly as intended by the artist. All done, “In admiration of music”.
Being a loudspeaker company, we fully understand the importance of a high performance driver. It was a big surprise for us to discover that within the headphone industry, drivers are often considered as cheap commodity components, with no real engineering attention paid to them.
The DALI IO-4 headphones utilise a high quality custom designed driver with a large 50 mm diaphragm and an optimised neodymium magnet system to achieve low distortion, minimal colouration and accurate dynamics throughout the entire frequency range.
The large diameter driver ensures linear operation with minimum compression. This, together with the well controlled breakups of the paper fibre cone diaphragm means that even the most minute music details stand out crystal clear. It also means that the sound never gets tiring, even after hours of listening.
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.
