Sound Oasis Pink Noise Bluetooth Sound Machine for Sleeping, 20 Non-Looping Soothing Sounds with Speaker & Memory Function, Portable Sleep Sound Therapy for Home, Office or Travel

I have always had trouble sleeping from being a teenager until now in my 70's. As a light sleeper, I seem to hear every pop and crack in the house at night and that keeps me awake. Plus, my mind won't shut off either as I am listening to the night noises and going over the day's activities in my minds eye. Our daughter and her husband take a fan with them when they travel and also use the fan in their bedroom at night to block outside sounds and give them enough background constant noise that other sounds in the house don't wake them up. My brother does something similar. So, after all these years, I decided to look for something smaller than a fan that was easy to use and could travel with us without taking up too much room. Looking through my favorite on-line store, Amazon, I ran across this particular sound machine which had pretty good ratings. It was more expensive than many listed, but I like to go for quality. Plus, it has a choice of 20 different sounds to choose from where many of the others only had 10 sounds or less. And, the sounds are loaded on a MicroSD card which means you can add new sounds and are not stuck with just the canned sounds that come with less expensive sound machines. So, I chose this particular sound machine.Impressions - This is really small, but t has some weight to it so does not feel cheap. The speaker is in the top and has a nice sound quality. Controls are simple, but you have to read the instructions to get the hang of how they work since some are dual use. There are 3 buttons located on the bottom of the front side. The middle is the power button. You have to hold it down for several seconds to turn it off and on. the other 2 buttons are + and - so a quick push of either adjusts the volume. If you hold the + or - buttons down for a couple seconds, the box goes to the next sound clip. So, you cycle through the list of 20 sounds by holding down the + or - buttons, listening to the sound, and going on if you don't like the sound that is playing. There is a card in the product box that lists all the sounds. Volume is good and has a pretty good range from low to high.The battery is rechargeable and seems to last a good time. One night, I left it unplugged and it ran for 5 hours and was still going strong when I turned it off. So, length of time on the battery might be variable depending on how loud you have the box turned up. I have it turned down to fairly low and it lasted for at least 5 hours. The unit comes with a USB charging cord. You can plug it into a USB port of a computer to charge it or you can use the wall plug of your cell phone charger to plug the cord into and charge via a standard AC outlet. This unit does not come with the AC wall converter plug but any cell phone charger plug with a USB port will charge this nicely.Another nice feature is its bluetooth capability. On the bottom of the box is a small button (hard to see) with the letter M on it. You can turn bluetooth on and off with this button. Turning it on, my Motorola android smartphone paired right up with it. And now, you can play any music from your phone through the sound machine speaker - cool.My only complaint about this machine is that there is no fan noise in the 20 different sounds that come with this machine. The fan noise - like a box fan - was important for me to have on hand. It does have a microSD card with the 20 mp3 sounds on the card and this card can be replaced with different cards that have other sounds stored on them. In fact, you can purchase more sounds from Sound Oasis to get what you want. However, at $4.99-$5.99 per sound, it can get expensive. My solution was to find a free sound app in the Google Play store that has the fan sound I wanted and I can play that sound through bluetooth to the Sound Oasis machine. That saves me a few dollars but it means I have to have my smartphone plugged in next to my sound machine and turned on all night. So, it depends on how you want to go. My suggestion to Sound Oasis is to drop one of the too many sounds that have water of some sort flowing, splashing, dripping, raining, etc. and add a box fan sound to replace it. Most people like the sound of a fan background when they are sleeping and this would make the Sound Oasis box complete.Bottom Line - This is a great sound machine of high quality and great capabilities and I am very happy with my purchase. I like the Pink Noise sounds and I have found that the constant pink noise running all night calms my active mind and allows me to get to sleep a lot faster. Plus, I seem to sleep a lot deeper which means I actually get up in the morning feeling a lot fresher than I ever used to. One of the 20 sounds that come with this machine should be a box fan. It does have pink, brown, and white noise sounds to pick from along with the many kinds of water sounds, birds chirping and one music sound that's kind of Zen-like.Update - 9/9/2019Well, this device is more versatile than I thought. After using it for a while, I still give it 5-stars. I also discovered that I can download any mp3 sound file from the Internet and load it onto the micro USB card in the sound machine and play it. I have taken the USB card out of the sound machine and plugged it into my computer with a microUSB to USB adapter, moved all the sounds I don't like onto my computer for perhaps future use, and kept only the sounds I like on the card. Then, I found some desk/floor fan sounds on the Internet (free) that were about an hour long and loaded them onto the microUSB card and plugged it back into the sound machine. Now, I have all the sounds I want on the card. And, I discovered that after the sound machine plays the short (1 hour long) mp3 fan sounds I loaded onto the card, it repeats automatically and replays the sound. So, at the end of the loop, the sound slowly goes down in volume, seems like it quits, and then starts over automatically. So, even shorter mp3 sounds will play all night. You could probably use it as a music player except it would just replay the same song over and over because it won't skip to the next mp3 on the card. The wife and I really like this machine. We just plug it in every night and unplug the machine during the day, so the battery is not subjected to the charger when it is not in use. In August, we traveled to Iowa and stayed at my mother-in-laws house for a few days. She lives in a very old house without too many wall outlets, so we had to use the battery in the sound machine for a few days. It lasted for 8 hours each night while we were there. I keep the volume less than half scale, so at least I know at lower volumes, it will last for 8 hours.

This is a very good sound machine for those with tinnitus. The sounds are custom designed by MDs who specialize in tinnitus. There is also a well-written booklet that explains tinnitus.If Sound Oasis is listening, here are some improvements I would suggest:1. The volume adjustment goes to quite high levels, but for me I prefer lower sound levels. The level I prefer is near the bottom, about two up from baseline. But one level is a bit too high, and the lower one a bit too low. It really needs levels in between. Would be nice if it had something like 32 sound level adjustments.2. Would like a timer on it. Because fortunately for me, my tinnitus is vascular-related. Whenever I get up at night to go to the bathroom, it gets noticeable when I go back to bed. But it usually subsides within 10-30 minutes after I lie down. So a 1-hour timer is fine for me.3. Would like a soundtrack that mimics riding a local train, where you can hear the rhythmic sound of wheels over the rails. The bullet train soundtrack is too innocuous and nondescript. Would also like a soundtrack that mimics the sound of a crackling campfire.I really like the tiny, compact size of the Sound Oasis, yet the sound volume is impressive. I don't know how anyone can sleep when it's gets that loud. That combined with the rechargeable battery makes it convenient for travel. Right now I am using the brown noise sound track.I still need to experiment with soundtracks with nature sounds to soothe my tinnitus, and for that, the Sound Oasis can't be beat. If you install the free Sound Oasis apps on your cellphone (there are two) you can access more tracks via Bluetooth. The variety of sounds is impressive. And with those tracks, you can use an equalizer on the apps to customize the soundtrack to suit your tinnitus.I also like the memory card concept. So you can change the built-in sounds on the machine, which you can't do with other sound machines.

Interesting little gadget. Will it cure my Tinnitus? Of course not. But I enjoy the wide variety of sounds, some of which help me get to sleep while others set the mood for a cozy night curled up with a mystery novel. It produces clear sound at a high to very low volume which is easily adjusted. Plus it takes up hardly any space. The silicone ring on its base keeps it pretty secure so a light bump doesn't even budge it.

If the sound quality is good then the selections are poorly recorded. Huge disappointment in the sounds or tracks provided. I already have a 'Homedics' white noise generator that has adequate sound. I'm so disappointed I can't even write a legible review.Only a SINGLE, ONE track with ANY tonal quality. The rest are a mishmash of inadequate sounds supposed to represent wind or rain or surf, a heart beat. Obviously blended together, seems like randomly.I bought this because I heard one a few times that had a very pleasant sort of new age sauna, resort spa sounds. I expected that but got junk. As I mentioned, there's only one track with any sort of coherent sound and its awful. Very short and just cut off after 20 seconds and restarts. No sort of blending just abruptly stop, restart.I wanted a sort of new age pleasant soundtrack. Got thus instead.
