I have a PreSonus Eris 5 Studio, and my DJ neighbor also has an Eris 5, an older version. After listening to all three versions with a Bluetooth receiver and a Motu M2, we both agreed that the Kali is a cut above: lower noise, deeper bass, and crystal-clear highs. Although I don't make music and only use them at home, my neighbor got a little scared and decided to sell his PreSonus. P.S. The gray color is amazing!!!
