No, N.O.W. is dual, asynchronous monaural. The two speakers are completely independent of each other.
Each N.O.W. speaker plays a different tone sequence every time it is used. When the two N.O.W. speakers are used together (as is intended) a completely “new now moment” is created from the interplay of the two tone sequences–as you listen.
This makes the sound quality of present moment always new, alluring and different. With regular use, your focus is increasingly shifted from thinking … to listening … to pure awareness of being–consciousness awakened from the dream of form identification.
