Work with confidence. Anywhere.
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.

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.

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.

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.

ARC ON•EAR changes the game

• True-to-life monitoring – Experience the natural perspective of high-end studio monitors in a properly tuned room.
  
• Pristine sound – Advanced acoustic modeling, not flawed convolution, ensures clarity and transparency.
  
• No guesswork – Get reliable, “first-shot” mixes that translate across every playback system.
  
• Consistency – Built-in amplification guarantees stable frequency response, free from amp-induced coloration.

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.

Effortless control

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.
