DALI IO-12 Premium Wireless Headphones - Dark Chocolate

The World's First Headphone With an SMC Driver Magnet

The DALI IO-12 is a closed-back wireless headphone built around a 50mm driver using DALI's patented SMC magnet system, technology inherited directly from the company's flagship EPICON loudspeakers. Active Noise Cancellation, Bluetooth 5.2, and a USB-C digital input round out the package.

Four ways to listen cover nearly every situation: Bluetooth for convenience, USB-C for a direct digital connection, active analog with the electronics powered on, and passive analog that works even with a fully dead battery.

A rechargeable battery delivers up to 35 hours of playback, or 30 hours with ANC engaged, and DALI built the IO-12 to run entirely from onboard buttons, so no companion app is required for everyday use.

Where the SMC Driver Earns Its Keep

Soft Magnetic Compound, Straight From DALI's Speakers

SMC stands for Soft Magnetic Compound, a material DALI uses in its driver magnet systems to reduce hysteresis and eddy currents, two forms of distortion that a conventional magnet structure can't fully avoid.

Each 50mm driver still uses the free-edge paper-fiber cone found across DALI's speaker lineup, but the SMC magnet behind it is genuinely new: the IO-12 was the first headphone anywhere to use this technology.

Active Noise Cancellation, Tuned for Balance

Three ANC modes cover different situations: On for maximum quiet, Transparency when you need to hear your surroundings, and Off when you'd rather save battery, with Wind Noise Suppression improving outdoor listening and phone calls specifically.

Bluetooth 5.2 supports AAC, aptX, aptX HD, and aptX Adaptive codecs, while the USB-C input handles digital audio up to 24-bit/96kHz for a genuinely direct connection to a computer or compatible source.

What Reviewers Are Saying

Home Theater & High Fidelity wrote that "those SMC-enabled drivers provide a sense of musical transparency that is both noticeable and remarkable."

TechRadar called it "dynamically agile listening inside your head," adding that the IO-12 offers "immersive listening without the extra parlor tricks."

The Ear found the IO-12 "quite addictive" sonically, noting its "airy and dynamic presentation grew on me" the longer they spent with it.

Who Is the DALI IO-12 Best For?

• You want DALI's most advanced driver technology: the IO-12 is the world's first headphone with an SMC magnet system, inherited from DALI's flagship EPICON loudspeakers
• You want ANC without losing hi-fi balance: the system is tuned to quiet outside noise without reshaping the music's tonal character
• You want to listen four different ways: Bluetooth, USB-C digital, active analog, or fully passive analog that works with zero battery
• You want genuinely long battery life: up to 35 hours of playback, or 30 with ANC on, with a full charge in under two hours
• You want DALI's flagship SMC driver — the IO-12 is the only DALI wireless headphone that carries it

How Does It Connect to Your System?

Pair over Bluetooth 5.2 from a phone, tablet, or computer for wireless convenience, or connect the included USB-C cable to a computer or compatible source for a direct digital connection up to 24-bit/96kHz.

The included analog cable works two ways: plug in with the IO-12 powered on for active analog listening, or connect it to a headphone amplifier or airplane entertainment system in passive mode, which needs no battery at all.

Pairs Well With

What finishes the system around a DALI IO-12:

• Headphone amplifiers — for driving the IO-12 in passive mode from a home system
• Headphone cables — a spare or longer cable for passive analog listening
• Headphone stands — a proper resting spot between listening sessions
• Headphone accessories — replacement earpads keep the IO-12 fresh over years of use

Frequently Asked Questions

What does SMC actually do?

Soft Magnetic Compound reduces hysteresis and eddy currents inside the driver's magnet system, two distortion sources a conventional magnet structure can't fully eliminate.

Does the IO-12 need battery power to work?

It doesn't. Passive analog mode works with a cable even when the battery is fully dead, making the IO-12 a true backup-free headphone.

Is there a companion app?

There isn't one required. DALI built the IO-12 around onboard physical buttons for volume, playback, calls, sound modes, and ANC.

Which Bluetooth codecs does it support?

AAC, aptX, aptX HD, and aptX Adaptive. Codec availability depends on your source device — aptX variants need a compatible Android device rather than an iPhone.

How is the IO-12 different from the iO-8?

The IO-12 uses DALI's flagship SMC driver magnet technology and a wider specified frequency range; the iO-8 shares the same connectivity and battery life at a lighter weight and lower price.

Are the earpads replaceable?

Yes. DALI designed the earpads to be swapped out, extending the useful life of the headphones well past the first set wearing out.
