From your DAW to the
phone speaker in three steps.

WHY IT MATTERS
Check your mix where
Check your mix where
people actually listen.
A mix has to sound right everywhere, so you check it on every kind of speaker, from big monitors to the worst little ones. The phone is the one most of your audience will use. MARS puts it next to your monitors: switch to it while you mix, in real time, without bouncing a file.
PRO TIPFor the full MARS experience, take the phone to the bathroom and sit down. Let’s be honest: that’s where a good part of your audience hears your work, through this very speaker, in a small room of hard, echoing tiles. If your mix survives that, it survives anything.
