THE GOOD: Sound+Sleep tends to be effective due to its ability to produce dynamic, varied and realistic sounds.
THE BAD: Main negatives include a high price, somewhat limited volume potential, and questionable reliability.
THE MACHINE: The product produces ten natural sound recordings. It uses adaptive technology to detect background noise and change its sound to mask it. The machine is made by Adaptive Sound Technologies (in business since 2008).

The table shows how Sound+Sleep rates compared to the average sound machine.
|Owner satisfaction||B-||Ecotones has 81% owner satisfaction.|
|Price||d||Around $100 at Amazon. The average price of a sound / white noise machine is $56.|
|Value||b-||The advanced features and capabilities of the Sound+Sleep do not quite make up for the relatively high price, say at least 10% of owners.|
|Reliability||C||About 8% of owners report problems within the first year. This rate is slightly better than that of other sound machines that use electronics to produce sound.|
|Sound quality||A-||Sound quality and realism are good, often better than those of other sound machines.|
|Loops not noticeable||A-||Most owner report that there's no annoying and distracting repetition in the sounds. A small number of owners with sensitive hearing can pick up on the loops, however.|
|Volume potential||c+||A lack of adequate volume is reported by about 6% of owners. Another complaint is an inability to determine the volume level by looking at the controls.
