First plug-in to enable mixing and mastering on

The truth about studio headphones

Reference headphones don’t exist.

Every set of headphones sounds different due to physical properties and limitations of materials and composition. None is neutral enough for critical listening.

We measure the sound of specific headphones and create a digital profile to correct them through processing in a DAW plugin. With the advanced technology of our DAW plugin, you get absolute accuracy with shocking simplicity.

Word from the industry

I had practicality retired my HD600's when I came across Sonarworks. I downloaded the free demo and to my surprise the headphones came alive! I've now reincorporated them into my critical mix decision making. I can now carve out offensive frequencies plus add the perfect amount of weight and clarity to my mix with great confidence.

With the Sonarworks headphone correction system, I can take my sessions on the road, and pick up right where I left off in the studio. The transition from monitors to headphones has never been smoother.

After I discovered the Sonarworks Headphone plug-in, it became an indispensable tool when I’m using headphones to record, edit and mix. I like to work in-the-box on my laptop and this tool gives me more confidence and accuracy. Also it brought more freedom for the way I produce in a traditional studio environment.

Benefits of headphone calibration

Tap into the full potential of your headphones!

Hi-end studio sound from your headphones

Headphone calibration is the process of measuring and adjusting the frequency response of headphones in order to precisely match flat and neutral sounding studio monitors in a well treated studio. Standard studio headphones are transformed into perfectly-engineered precision devices. By giving yourself the gift of accurate sound, you can mix and master with total confidence.

Abbey Road on the road

Not all of life happens in comfortable studios. Take your reference sound where your work or inspiration takes you. Our digital solution delivers the accuracy you need, anywhere you are. Bring your headphones; bring your laptop. That’s it.

Collaborate with ease

Let’s get everyone on the same page, finally. All calibrated headphones retain the same tonal balance. We’d like to announce the official end of never ending arguments caused by different sound references.


Reference sound everywhere

Reference 3 Systemwide upgrade calibrates all of your outgoing audio - dependable sound standard goes outside of DAW for seamless production and referencing. No more dragging files into your DAW project just to have a listen or figuring out how to check if your kick blasts as hard as the best of them on Soundcloud.

Exceptional sound delivered through unprecedented innovation.

Sonarworks uses a set of patent-pending technologies developed in our laboratory to measure and calibrate headphones.

We perform each measurement process using our proprietary Headphone Acoustic Power (HAP) measurement system. The system is capable of measuring the frequency response from any pair of headphones as perceived by human ears.

In the press

The Sonarworks Reference plug-in makes a difference that is out of all proportion to its modest price, and is capable of turning an unremarkable pair of headphones into a serious mix tool.

The result was huge, and massively for the better.
Attack Magazine, February 9th
Sonarworks Headphone Calibration software has not only upgraded my already brilliant KRK KNS8400 headphones but also given me back a workflow that for many years I wasn't comfortable using.
Pro Tools Expert, September 11th
The idea of making any pair of headphones flat and faithful is very appealing, especially for the price. And the fact that you can send in your headphones to have them measured pushes the concept even further.

Frequently asked questions

While we have the utmost respect for many headphone manufacturers about what they have given to the industry, yet our measurements show that there is no perfect headphone. Every product has its limitations that are usually dictated by their design (and sometimes the marketing department). There are many outstanding headphones currently on the market, yet there are none which wouldn’t benefit from our software. Some acoustic problems are extremely hard to overcome by physical design only; hence our software gives the headphone the help it needs to perform to its fullest potential.

Yes, that is our claim given that the same reference target is set for both headphones. This is of course subject to small differences imposed by the physical limits of the headphone and differences in headphone THD profiles.

All measurements and calibrations are done to ensure flat perceived frequency response at 83dB. This is one of the commonly used sound pressure levels in many studios.
