	iAwake Technologies – Audio SerenityI would describe as calming and harmonizing. The sound is pleasant and can be listened to for hours in the background without being perceived as disturbing while reading or having a conversation. It also did not interfere with highly concentrated tasks, if volume is low. ~ Alex $15.00$37.00
