TRUE HI-FI PERFORMANCE

Hi-Fi speakers for your head

Designed and engineered using the same sound principles as our full-size loudspeakers, DALI IO-8 wireless Hi-Fi headphones deliver an exceptionally lifelike performance. With features like our custom-designed 50 mm drivers with paper fiber cone and electronics inherited from our acclaimed IO-12s, Hi-Res-certified DALI IO-8 headphones are true Hi-Fi speakers for your head.

Paper Fiber Driver Diaphragms

DALI speaker driver diaphragms are made exclusively from proprietary paper and wood fiber materials refined over decades of development. A closely related paper fibre material is used in the IO-8 drivers that employs randomly aligned fibres of variable length to create a light yet stiff diaphragm that offers optimal damping. The result is natural, relaxed sound quality brimming with detail.

AUDIOPHILE ACTIVE NOISE CANCELLATION

Leave the world behind

Silence the distractions and enjoy every detail of your favorite music. Our cutting-edge Audiophile Active Noise Cancellation technology delivers a truly immersive listening experience, while leaving the music untouched. And with three ANC modes, you can tailor the IO-8s to your situation, whether you're relaxing at home or on your daily commute.

Hi-Res Audio Certified

The IO-8 supports from 16 - 24 bit audio with sample rates from 32 – 96 kHz. The DALI IO-8 internal audio processing is based on 48kHz audio sampling – the same rate as most USB and Bluetooth aptX Adaptive streamed audio sources. This means that sample rate conversion, a process that often results in audible artefacts, is unnecessary. The result is clearer and more insightful sound quality. The IO-8 also supports up to 96kHz sample rate over USB, with full 48 kHz audio bandwidth and no down sampling applied, for ultimate sound quality.

35-HOUR BATTERY LIFE

Extended listening between charges

An advanced lithium-ion battery delivers up to 35 hours of peerless playback so you can enjoy extended listening on a single charge. And with battery-level LEDs and a voice prompt to tell you how much charge you have left, you can just lean back and focus on enjoying your favorite music.

DUAL SOUND MODES

Two sound profiles to match your taste

Tailor the performance to your own style with 'Hi-Fi' and 'Bass' sound modes. Whether you like your music as the artist intended or you prefer a more punchy, bass-focused performance, DALI IO-8 headphones let you listen to your music just the way you want it.

WIRED OR WIRELESS

The only headphones you'll ever need

Whether you're plugged into your Hi-Fi, immersed in your vinyl collection, or paired with your smartphone enjoying on-the-go music, DALI IO-8s harness advanced technologies like Bluetooth® aptX Adaptive to deliver an astonishing musical experience, however you use them.

Connection Modes

Wireless Active Mode

Switch on and connect your headphones via Bluetooth to a source device such as a smart phone, tablet or computer. All the IO-8 active noise-cancelling, DSP and sound mode functions will be available. This is the best connection mode for headphone use on-the-go when travelling, for freedom of movement and for avoiding cables.

Wired Active USB Mode

Switch on and connect your headphones using the supplied USB cable to a computer with a USB audio output socket. All the IO-8 active noise-cancelling, DSP and sound mode functions will be available.

Analog Wired Active Mode

Switch on and connect your headphones via the supplied 3.5 mm mini jack cable to a source device with an analogue jack output. All the IO-8 active noise-cancelling, DSP and sound mode functions will be available. This is the best connection mode to use with a source device f itted with a conventional analogue headphone output. For instance, use this mode when flying/connected to in-flight entertainment systems.

Analog Wired Passive Mode 

With your IO-8 headphones switched-off, connect them using the supplied 3.5 mm mini jack cable to a source device with an analogue jack output. In this passive connection mode none of the IO-8 active noise-cancelling, DSP and sound mode functions will be available. Use this connection mode if your IO-8 battery is exhausted or simply if you prefer the inherent sound of a particular source device or headphone amplifier. Headphone volume control in passive, and wired active mode will default to the source device.

About Dali

DALI, Danish Audiophile Loudspeaker Industries, was created in 1983 to meet the demands of Scandinavia's leading audio retail chain's customers, who were asking for loudspeakers that existing brands couldn't offer. DALI loudspeakers would offer outstanding performance and natural sound at competitive prices. Inspired by a firm belief that we could create a unique sonic identity that focused on musical realism and sound integrity, we set out to redefine the reproduction of sound.
