Sonet QT™ Sonet QT™ Noise Masking and Speech Privacy System - Base System (1 Controller, 2 Emitters, Power Supply & Accessories)

I had originally purchased this device in 2004 to mask external sounds in my work environment but shortly found that it works great in the bedroom helping me stay asleep and get to sleep faster. I placed the emitters on each side of my bed. Unlike some devices, like a fan or others that simulate sounds mechanically the Sonet QT, with the ability to easily adjust the volume sounds like a high quality AC unit. For the most part it is a vary reliable device, it was running non-stop (16+ Years) up until December 30, 2021 when my home burned in the Colorado Marshal fire.
I tried purchasing a cheaper unit for my new location but quickly found the Sonet QT worked the best for me and quickly purchased a another one.
Purchasing a unit for my son, he found it easier to focus and study, being less distracted by surrounding apartment noises.

Was a little apprehensive when I saw all the cords that came with this product. After hooking it up, we've used it non-stop in our office. It's easy to hook up and use instantly. The white noise is actually somewhat soothing and this product is worth every penny that was paid for it. Many meetings are held in the office to which this is attached and not a peep can be heard from outside. I highly recommend this product.

seems to work as advertised.

This system has been great for our therapists' office. We had a bit of a sound problem and now we can't hear each other in between offices. We also all love is that it doesn't have that tinny grating sound that our cheaper white noise machine had. Love it.

This is a wonderful product. Can adjust sound from quiet to very loud. This is my second machine they last for many years of every night use.

Works as advertised. I am very pleased with the product. If I were doing it again though I would take advantage of the discount and get 2 more speakers.
