The ratings below are based on at least 900 actual owner experiences and reviews collected from diverse, credible sources including online message boards and product review sections on retailers' websites.
|Owner satisfaction||a||Ecotones has 88% owner satisfaction ( ) which ties it for first place with Marpac Dohm.|
|Price||d||$90-$130 is the price charged by most retailers, including Amazon and Walmart.com. The average price of a sound / white noise machine is $56.|
|Value||b||Although the Ecotones is pricey, reviewers generally believe it to be worth the cost.|
|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-||The product uses 18-bit digital audio which is higher quality than CD audio. The result in terms of sound quality and realism is good, often better than other sound machines.|
|Loops not noticeable||A-||Most owner reviews 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. On the favorable side, when set to adaptive mode, the Ecotones can detect background noise and then dynamically change its recordings to mask it. For example, if a police car drives by with sirens blaring, the product is designed to detect this noise and adapt its sound gradually to drown out the sirens. Ecotones also features a manual mode that provides consistent sound.|
