The DALI IO-4 luxurious wireless headphones are designed for maximum comfort with a durable design and a natural, transparent sound performance. Featuring a class-leading 60 hour battery life. Designed and developed from the bottom up in our headquarters in Denmark.
 
ULTIMATE COMFORT
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.
 
EPIC 60 HOUR BATTERY LIFE
The long battery life grants freedom from worrying about running out of power. Go longer with the large capacity, high-quality li-ion battery featured in the DALI IO-4. DALI provides best-in-class with the incredible new class leading 60 hour battery life in the IO-4; enough to go for days without charging.

DALI IO headphones 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.
