Earprint™ by Psyx delivers an unparalleled listening experience in any surround environment (especially in the car). Welcome to portable luxury audio.

Presets are so 80's. Each of our 6 color profiles account for changes in listening environment, user preference, tempo/era/genre, etc. Tap the color to engage, then tap again to turn off. "Off" let's you hear the song in its original, unprocessed state. We suggest you choose a color, turn it off, then choose another color, turn it off, etc. You will always prefer 1 color you like the best for that song in that listening environment. Earprint™ will remember your selection for the next time you play the song.

We are published contributors to the science of human auditory perception and have over 40 years of experience developing technologies for each stage in the ecosystem: content creation, mixing and editing, broadcasting and streaming, and consumer playback. We develop the most advanced and reliable psychoacoustic technologies in the world today used in satellite radio broadcast, radio, television, digital cinema, music, gaming and consumer electronics.

We developed the Psyx app after more than a decade of research and innovation in the areas of listening fatigue and human perception. Compressed music causes hearing fatigue for a number of reasons and we have identified the 4 main areas of concern:

Dynamics, Image Width, Artifact Management, and Articulation.

EarPrint Color Profiles:
We have included 6 EarPrint Color Profiles that allow you to select the best possible fit based on the following factors:

1) The amount of compression in the song
2) The era of the song
3) The playback medium (cars, docks, soundbars, home systems, etc)
4) Background noise
5) The condition of the listener's hearing
6) The listener's expectations

There is no "correct" color, and we purposely do not use terms like "pop" "rock" "hip hop" because that has nothing to do with what you want (or expect) to hear. Choose the color YOU like the best, and Earprint will even remember it the next time it is played. Each color profile displays a description, an image map illustrating front vs. rear image management, and its level of artifact correction.

Earprint is a technology that allows us to capture an exact 3D model of a person's hearing system. We have been working with Grammy award winning recording artists, producers and engineers to offer these additional Earprint Colors within the Psyx app (coming soon).

Power Efficiency:
With peak power of 50 Million Instructions Per Second (MIPS) applied to 170+ discreet psychoacoustic algorithms, Earprint produces unrivaled performance while remaining fully optimized and power-efficient, boasting up to 18 hours of continuous playback.

Psy(x) Audio was formed to address the digital audio market based on four core areas of proprietary innovation: Pyschoacoustics, Pre-Processing, Post Processing and Surround Sound. We work closely with the most influential Audio Scientists, Artists, Music Producers, and Engineers in the world to ensure that our technologies deliver the absolute highest quality of experience available.

Thank you!

Worth it but still has a way to go.


This has really changed the quality of the music I listen to while I'm in my car. You can't beat the quality.
My only wish is an upgrade to the interface. I find it hard to advance to the next song without taking my eyes off the road. For that reason I find myself using Leech Tunes more often.

Beautiful listening experience!


Wonderful app for fine tuning your listening experience. If you enjoy the finer elements of music, this really allows you to hear more. Love it!

THE BEST Music App in the Marketplace!


I was an original purchaser of this app and had no problems installing the new version. This is still by far the best music app I've ever used for music.
