We purchased the Ecotones machine in May of 2011. It has been an excellent buy and has helped greatly to filter out nighttime noises that occur in our neighborhood at random times. We especially like the volume control and the way the sound volume automatically adjusts to the level of external noises. Our favorite setting is the waterfall. And the company provides great support. After a recent storm-related power surge, the unit stopped working. One short email later, we received a new micro sd card and instructions to replace the damaged one. After a few minutes, we had a working unit again. Kudos to Jack and the Adaptive Sound Technologies team!

This is the most fabulous item EVER for those of us with trouble sleeping. I read the hundreds of reviews with mild disbelief and hope, ordered mine and have nothing but good feelings and smiles for it. The design is sleek and unique. The buttons are logical and clear. The support is excellent - call just to let them know you like their product. I grew up in Hawaii and now live in Montana under an active teenager and I promise the wave sound is bliss. You set your own sleep volume and if there is any noise it goes up on it's own to hide the other sounds and keep you in peace. LOVE IT. And I get more sleep so my husband loves me more too!

It’s cool and works..just my son likes to grab at things that he can reach from his crib that couldn’t use it on the crib and had no where else to put it.

We have absolutely loved our machine. The speaker is far superior to any of the cheap units offered at Bed Bath and Beyond or wherever. And there's no looping to drive you crazy! We mainly use the white noise setting for our daughter but have tried out the others for ourselves and liked them all. (The fireplace is a favorite of mine.) Highly recommend.

Wie gewohnt , schnelle Lieferung, direkt ausgepackt und ausprobiert. Sehr leicht macht einen wertigen Eindruck, Sennheiser halt, Sprach- und Tonqualität meiner Meinung nach gut. Alles in allem bin ich sehr zufrieden, habe heute Abend eine Online-Schulung, der erste längere Test!

Its good, I was surprized to see, its too small, fast and compatable with my PC. Good One.
