"The sound out of the box was pretty damn good for an earphone in this price range, but when I installed the XTZ Player and turned on the Dirac DSP correction, Just WOW. "

Earphone Sports

The idea behind this project was not only to create a good earphone, maybe with an excellent price/quality ratio, but to build something revolutionary, something that expresses our passion for music and technology. The in-ear headphones are equipped with the best technology in every part. In addition to the excellent membrane there is has been optimized in many other areas. A particular focus of the earphone lies on perfectly hiding ambient noise, so that undisturbed music enjoyment is possible. A calm and relaxing atmosphere is the result. Of course also the look and feel of those small “speakers” play an important role. The clean metallic design thereby ensures enthusiasm. That's still not enough , we were even able to solve the problem of permanently wired and tangled cord. The two earphones are on their backs each magnetic and therefore hold together perfectly. The cable is particularly impressive itself. It unravels literally on its own and without any help. This is made possible by the flat construction and low friction of the cable together. Disturbing difficulties and even damage to the cables therefore belong to the past. The sport version of EarPhone-12 comes with a microphone, mounting clip, ear hook and new foam plugs thats adjusts to the ear.

DSP technology from Dirac Research

Dirac Research owns the market’s most advanced technology in digital sound processing (DSP) and consequently it´s used by several luxury brands like BMW, Bentley, Rolls Royce etc. The advanced algorithm we use optimizes both frequency response (amplitude) and impulse response (time domain). Applying Dirac’s DSP optimization, the result is an impressively balanced and flawless sound, which can  truly be described as breathtaking.

(DAP) Dirac Audio Processor for PC / MAC

The DAP is optional which means you can also buy and use the Earphone Sports at your computer without this programm. The software cleverly tricks your computer into believing that the DAP is a normal sound device, so all audio, regardless of where it’s coming from, gets sent though Dirac’s DSP. It then gets forwarded to your “real” sound card / device and provides beautiful sound, especially tweaked for the Earphone Sports. The DAP appears as a simple window on your desktop and allows you to easily pick your favorite sound character depending on your preference, mood and the type of music you’re listening to.
