This is the Sound + Sleep SE by Adaptive Sound Technologies — widely regarded as one of the best premium sleep sound machines available.
The unit has been fully tested and works great. All sound options play clearly, buttons respond properly, and volume control functions as it should.
Unlike basic white noise machines, this model uses real recorded sounds (not looping digital noise), which creates a more natural, non-repetitive listening experience that helps block unwanted background noise.
