IK Multimedia ARC On-Ear, Standalone Headphone DAC and Amplifier

Traditional headphones — even “reference” models — don’t tell the whole truth. Their frequency response is never perfectly flat, and their exaggerated stereo image alters your perception of balance, timbre, and space. The result? Endless revisions, ear fatigue, and mixes that don’t translate.

ARC ON•EAR is a revolutionary standalone headphone DAC and amplifier that instantly corrects your headphone's response and recreates the experience of mixing on professional studio monitors.

For the first time, you can mix, master, and produce with total confidence — anywhere.

Unlike conventional correction plug-ins or virtual control room systems, ARC ON•EAR doesn’t sound artificial or over-processed. Instead, it delivers the precision, depth, and trust of a real control room — inside your headphones.

No guesswork, no compromise:

Mixing on headphones has always meant compromise.

Even “reference” headphones color your sound, while exaggerated stereo width makes spatial judgment nearly impossible.

ARC ON•EAR solves both problems — restoring a neutral frequency response and a natural stereo image — so you can trust what you hear every time.

A reference you can trust:

Every pair of headphones has its own sonic fingerprint.

ARC ON•EAR uses precision calibration profiles, measured with state-of-the-art reference rigs, to ensure accurate, transparent, and reliable sound. With support for hundreds of popular headphone models, you’ll experience your mix exactly as it should sound — clear, balanced, and true.

Studio monitors — in your headphones:

Unlike plug-ins or impulse-based “virtual rooms,” ARC ON•EAR uses advanced physical modeling to recreate how real studio monitors behave in an ideal acoustic space.

No artificial reverbs. No timbral coloration. Just the natural depth, width, and clarity of a real control room — right in your headphones.

Accuracy begins with the amplifier:

ARC ON•EAR’s amplifier has the lowest distortion across the entire audio spectrum compared to leading high-end interfaces and laptops.

When pushed to their limits, typical headphone amplifiers reveal their weaknesses. The plot shown here compares the total harmonic distortion of leading audio interfaces and high-end laptop headphone outputs with ARC ON•EAR, measured at high volume on a low-impedance (32 Ω) headphone.

The behavior of a headphone amplifier directly affects what you hear. Even high-end audio interfaces and mixers can alter a headphone’s frequency response — sometimes subtly, sometimes significantly — depending on the model and its output impedance.

ARC ON•EAR eliminates this variable. All calibration profiles are created using the exact same amplifier circuit found in the product, ensuring precise, reliable, and repeatable correction across all headphones and listening sessions.

Virtual Monitoring that goes beyond:

Instantly test your mix on a wide range of playback systems — without taking off your headphones:

• Studio monitors
• Smartphones
