From Wicked Audio website - Most music comes from a high-end recording studio where artists spend bookoo bucks to produce the loudest sexiest sound possible. Chances are the music you listen to has been compressed and lacks the same quality it had when recorded in the studio. This is where the Bongiovi DPS takes the reigns and remasters your music. Tony Bongiovi's algorithm has been custom-developed for the acoustics of this headphone. This algorithm remasters all the audio and brings back high and lows that are lost during compression. After the audio is remastered you're left with crystal clear music that sounds like the came straight from the studio. Now you can hear every detail; even the spit hitting the mic.
