The two units have the same sound and are both App compatible with either App. The Tuft and Needle SNOOZ has an easier tone adjustment with a refreshed design. The colorway is exclusive to Tuft and Needle and it is still compatible with the SNOOZ travel case! The fabric on this design is not interchangeable, it is affixed to the unit itself.
The SNOOZ comes in the two colors (cloud and charcoal) and the wrap is interchangeable.
