Thinking of buying expensive earphones? Try this first! Dirac HD Player is an easy-to-use music player based on advanced technology that genuinely improves the sound from Apple’s original Earphones, EarPods and In-Ear Headphones.


- NO SOUND EFFECT, but instead tailored to control the acoustic properties of the original iPhone earphones – the only way to achieve a genuine improvement that causes less listening fatigue.

- NATURAL SOUND with increased clarity in music and voices. Deepens the bass, removes resonances and acoustic problems.

- NO COMPLICATED SETTINGS, select your earphone model and hear the difference by switching ON/OFF.

- VERY COST EFFICIENT and green alternative to buying expensive earphones.

- USES THE USUAL SIMPLE FUNCTIONALY that you are accustomed to with your iPhone, while the optimization runs in the background.

Listen to music from your iTunes library with improved sound quality. No technical know-how is needed. Under the hood however, it uses technology normally used in some of the world’s best hifi, studio and cinema sound systems.

Due to physical constraints, it is impossible to design a perfect earphone solely with hardware components. Dirac’s audio scientists have made precise acoustic measurements of the original iPhone earphones, allowing a tailored digital software processor based on Dirac HD Sound® technology.

Like a pair of glasses improves the perception of poor eyesight, this technology improves and corrects the sound, so that it becomes cleaner and closer to a perfect sound reproduction. It has nothing to do with sound effects or graphic equalizers used in other apps.


The sound improvement is tailored for Apple’s original Earphones, EarPods and In-Ear Headphones. The app should not be used with other earphones.

Utilizes the iTunes music library.

DRM protected music is not playable by Dirac HD Player (or any other 3rd party app).

Please note that iTunes Match and iTunes in the Cloud not yet fully supported.
