The quality of the Dreamie's sound is what initially sold me during my demo at CES, and it holds up in daily use. The Dreamie has a 50 millimeter speaker inside, and the 360-degree grille on the bottom of the device makes it so the sound seems to come from everywhere. (My cats were extremely confused when I first turned it on). It really fills a room, and you don't have to crank it up to achieve that. When Bedtime Cue comes on, I typically turn it down to about 25, and then raise it back up to 45 when I flip it to Wind Down mode. I've never once set it higher than 50, and the alarm in the morning has still been loud enough to wake me up.
