This model is an update to the one I purchased in 2014 with new improved features and design. I appreciate the sleek look, easy to use clock and alarm settings and many, many installed sounds with simple adjustable volume control. The backlighting feature is also revamped with more settings. I use this machine by my bedside to muffle street sounds and noisy neighbors while living in a multi-family apartment building with inadequate insulation. I highly recommend Sound Oasis for price and quality. I would be lost without it.

A gift
I have one of these that’s really old. 15+ years. Crazy. This was a gift for my daughter.

Tinnitus is lessened. Thankfully!
It has similar sounds as the more portable system. Anything to lower the tinnitus I can't get used to yet.

I just felt compelled to write a brief review about my "Sound Oasis" sleep machine. I have an older model (S-650) which has been upgraded by the S-680 but I am extremely happy with the one I have. I originally bought it to help block out street noise from my apartment but also now use it because I have severe tinnitus. My Sound Oasis came with two sleep card, each with numerous different sounds. I also purchased one sound card designed specifically for tinnitus. I love the fact that I can set the timer to go off after 30 minutes (or longer) so once I fall asleep, I am assured that it has turned off. Besides being very happy with this product, I cannot say enough about the customer service. If a consumer has any questions or concerns, the company responds almost immediately and will bend over backward to make everything correct. I highly recommend this company and their products.

Changed my life
I just want to say that sound oasis has changed my life! I know that sounds dramatic, but I sleep so much better now! The sound gives me something to focus on besides my discomfort and then I wake up the next morning!
