Attune plays your own music, loudness matched, and asks which of two tunings you like better. About a dozen answers later, you have a personal EQ curve for the headphones on your head. There is no target you have to agree with, no preset to take on faith, and no subscription.
Free. No account, no card.
Building a headphone? I take outside work. DESIGN REVIEW →
Everything happens on the track you already have playing.
Every headphone in Attune was measured on my own rig. If yours isn’t there yet, you can import a measurement you already have (CSV, AutoEq or squig) for free, or send your pair in and I’ll measure it.
About a dozen short comparisons, blind and loudness matched, so louder can never pass for better. It crossfades between the two instead of muting, so the only thing that changes is the sound.
Your answers build one curve, saved per headphone. One saved sound is free and stays free. Pro is a one-time $39 unlock for unlimited sounds and AutoEq export. It is not a subscription and never will be.
EQ moves tonal balance and nothing else. It won’t buy you resolution, soundstage, lower distortion or different driver physics, and nothing on this page says otherwise.
Because I wrote the method down and you can check it. A measurement you can’t audit is just a picture of a line.
A miniDSP EARS Pro with per-unit serial-matched calibration, using the IEC 60318-4 couplers that the industry rigs use. It is a house reference rather than an industry reference coupler, and I label it that way next to every graph.
I adjust the headphone for seal and for sound, the way you would settle in to listen, rather than dropping it on at random. You don’t listen at a random seating, so I measure the good one and then show I can find it again.
Every measurement I take goes up at full resolution under CC BY-NC 4.0, with the rig and the date on it. See the measurements.
Every correction you can buy is built from somebody else’s sample of your model. Send me yours and you get the curve of the pair actually in your hands. I publish it either way, flattering or not.
I measure it on the EARS Pro, seated for best fit and labelled by rig, and send it back in about a week. It gets its own page here, credited however you like. Unit variation is real, and what your specific pair measures is exactly what Attune turns into a personal tuning.
Nine plugins on one shared DSP library, built alongside the measurement work. Level is the same correction engine Attune runs on, as a plugin for your DAW.
Paid public beta. The store is built and tested but not switched on yet, so those are the prices rather than a checkout. Leave your address on the plugin page and I’ll tell you the day it opens.
An open source headphone you can build and service yourself. Sprung steel bow, commodity pads and printed parts, designed so a tweaker can take it apart.
Every first-party measurement published raw and at full resolution under CC BY-NC 4.0. Flattering or not.
I wrote it from the same bench, using the same method, that produced the measurements on this site.
