The DALI IO-4 Wireless Bluetooth Headphones use all of DALI's experience in creating high quality loudspeakers to deliver articulate and detailed headphones, complete with wireless Bluetooth connectivity to fully immerse you in the music and keep you free of wires for truly portable listening.

The DALI IO-4 headphones aim to produce a natural and authentic sound, using the same principles and design philosophy as the award-winning DALI loudspeakers. The headphones use high quality custom designed 50mm drivers with neodymium magnets for low distortion and accurate dynamics across the whole frequency spectrum. The larger size driver in the IO-4 headphones produces linear operation, and when coupled with the paper fibre diaphragm allows even the quietest details to stand out.

Boasting an incredible battery life of 60 hours on a single charge, the IO-4 headphones can be used for weeks without needing a recharge. Even with a depleted battery, simply connect the mini jack cable to listen to the IO-4s as you would ordinary headphones. A simple 2 hour recharge via the USB-C cable puts you back up to 100% for wireless listening.

The DALI IO-4 headphones connect to your device wirelessly over a high quality Bluetooth connection, allowing you to use the headphones without the restriction of a cable. Featuring Bluetooth 5.0, AAC, aptX and aptX HD, the IO-4s ensure your music is always of the highest quality. With memory foam ear pads and synthetic leather covering, the headphones keep comfort at the forefront of their design, allowing you to listen for an extended time period. The lightweight design helps add to the comfort, without compromising on the quality or durability.

The DALI IO-4 wireless headphones are available in two stylish finishes of Iron Black or Caramel White, suitable for any style or taste.
