Good for blocking annoying noises
I just got this little machine and it has very good sound quality and a nice variety of sounds - some I like better than others, but that's just me. I would give this 5 stars but I didn't realize that it doesn't have a cord to use in an electric outlet. You have to use a USB connection. However, it's my own fault for not reading the fine print in the description! Otherwise a great little machine.
