Work with confidence. Anywhere.

Traditional headphones even reference models dont 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 dont translate.

ARC ONEAR 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 ONEAR doesnt sound artificial or over-processed. Instead, it delivers the precision, depth, and trust of a real control room inside your headphones.

Headphone correction/virtual monitoring system

• Audiophile DAC and headphone amplifier with built-in correction
• Removes the guesswork from mixing on headphones
• Recreates the experience of monitors in a studio
• Virtually audition your mix on other top playback systems
• Control software to customize and load up to 5 profiles
• Support for hundreds of popular headphone models
• Rechargeable battery provides up to 4 hours of playback
• Digital and Analog audio inputs support all audio sources
  

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 ONEAR solves both problems restoring a neutral frequency response and a natural stereo image so you can trust what you hear every time.

ARC ONEAR 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 ONEAR 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, youll experience your mix exactly as it should sound clear, balanced, and true.

The graph above shows the wide variation in response curves of over 200 headphones IK profiled, highlighting the challenge of achieving consistency without ARC ONEAR.

Studio monitors in your headphones

Unlike plug-ins or impulse-based virtual rooms, ARC ONEAR 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 ONEARs 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 ONEAR, measured at high volume on a low-impedance (32) headphone.

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

ARC ONEAR 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
• Smart Speakers
• TV sets

With a growing library of virtual monitors, youll know exactly how your mix translates in the real world.
