DALI IO-4 headphones are designed for maximum comfort, featuring a sturdy construction and natural, transparent sound. DALI IO-4 is the best in its class in terms of battery life, offering up to 60 hours of playtime. They are designed and engineered from scratch at the Danish headquarters.
Immersive sound by DALI
The DALI IO headphones are designed and developed in Denmark, incorporating DALI's proprietary technologies. The specially designed 50mm driver with a paper fiber diaphragm delivers a natural, transparent, and realistic sound with minimal distortion and coloration, reproducing music as it was meant to be heard.
Long-lasting battery (60 hours)
IO-4 headphones boast the best battery life in their class, enabling up to 60 hours of continuous usage, eliminating the need for frequent charging for weeks. In case the battery unexpectedly runs out, the IO-4 can be switched to passive mode by connecting them to an audio device with the included 3.5mm cable. Charging to 100% capacity takes just 2 hours via the standard USB-C port.
Comfort and reliability
The IO earpads are made of memory foam, providing a perfect fit and maximum comfort while creating acoustic isolation. The earpads are covered with soft synthetic leather covers, chosen for optimal comfort and durability, which have been thoroughly tested in real-life conditions.
Connectivity options
For high-quality wireless audio, DALI IO headphones support Bluetooth AptX, AptX HD, and Apple AAC connectivity. The maximum audio quality is achieved when connected via the USB-C port, supporting digital audio streams from Windows or Mac devices.
