Review on Yogasleep Baby Soother White Noise Machine: Voice Recording, 5 Sound Options & Night Light - Sleep Aid & Registry Gift by Ryan Yap

I have now used this noise machine on about a dozen travels, including internationally. The USB power eliminates needing voltage converters or carrying the correct prongs. Everywhere has USB.Despite the small size, the unit has surprisingly deep and rich sound. Other electronic noise machines were thin and artificial compared to a mechanical noise source. But the Yogasleep fixes this!It's not very picky on location. I usually sit the device on the floor at the foot of the bed where the nightlight is handy, especially when I'm switching from city to city in a new hotel room every night. The sound quality and omnidirectional speaker makes the unit more or less independent on placement. It puts out plenty of volume.The bluetooth speaker function is a bonus function! Very handy in hotel rooms to listen to music or podcasts.TLDR: excellent USB powered travel bluetooth speaker, white noise machine, and nightlight. Five stars.
