Homedics White Noise Nature Sound Machines Homedics makes a line of popular white noise machines. The Homedic models have been well received by most users though there have been some quality issues. Homedics has recently updated their lineup of models and we hope that the new models will show a little better in the quality department. We hope to get some reliable user experiences with the new models soon. Starting from the lower end of the line; the SS-2000 replaces the most popular SS-200. The Homedics SS-2000 Nature Sound Machine has the same features with a new stylish design. If all you want is a sound machine, then this is probably your best choice.
