Adaptive Sound Technologies Sound + Sleep SE Noise Machine - White Noise Machine - Non-Looping Environmental/Nature Sounds for Sleep & Relaxation - with Timer & Headphone Jack - White/Silver

I purchased this item after comparing it with the LectroFan Evo and the Yogasleep Dohm, and ultimately settled on the Sound+Sleep SE. All of them are good, but this one is the most complete, especially if you appreciate rain and nature sounds. It gets quite loud, and the sound quality is what I would describe as HD compared to the others.The LectroFan Evo is more specialized in white noise and fan sounds. Its sound isn't as 'HD' but has a slightly warmer tone. The Yogasleep Dohm is for those who like simplicity and the convenience of pressing a single button. Its sound is relaxing, although it bothered me that I could hear a strange, high-pitched sound coming from somewhere mechanical, not the fan itself.This was definitely the winner for me due to its HD sounds, good aesthetics, no noticeable looping, and versatility of ambient sounds, plus white, brown, and pink noise, and fan sounds. The only downsides are the price and limited portability.

Works great. Use it for brown noise as I have tinnitus and this drowns out the ringing and lets me sleep.

I bought my Sound+Sleep SE a bit over five years ago and it's worked great that entire time. However just recently it has developed a glitch where after playing for several hours it'll suddenly emit a fast stuttering noise and then power off. I contacted the company's support department and they immediately responded (within seconds) and their belief is that the memory card has gone bad and they are sending me a replacement memory card first class free of charge. I'm totally blown away by this level of support, especially as the product is no longer under warranty. I wish all businesses operated at such a level.Now as to the machine itself, I love it, which is why I've used it every night for over five years. My favorite settings is the "Meadow" setting with both "Selection" lights lit. I do hit the Display button to turn off all the lights though before I go to bed. But I just love the crickets in that particular setting.

The first 2 units had electrical malfunctions out of the box... Feedback sounds from the speaker, on/off button not working unless the unit was unplugged then plugged back in, unit turned on, no sound from speaker. Both times I emailed Customer Support and they quickly agree to replace the unit. I'm currently awaiting the delivery of unit #3.Travel? Possibly. The unit is 6.5 inches wide, 5.5 inches deep and 4.5 inches tall.Sound quality? Good, the recording loops are virtually seamless.Number of sound selections? 11 realistic sound categories, or high/ low fan loops or white /brown/pink noise loops. Each category has 4 enhancements from which to choose. (eg rainfall, rainfall w/wind & light thunder, rainfall w/more wind & louder thunder etc)Timer? Yes or you can choose continuous play. Adaptive volume? Yes or you can opt to keep the sound at one level.Only one criticism of a particular sound selection: OCEAN has a LOT of base... think BIG angry waves on a beach. You can make the waves sound even bigger (as if a storm were offshore) or add birds/seals/buoys or add foghorns to the birds etc. I've heard better ocean sounds on phone apps...I'm disappointed they didn't start with more treble: lapping lagoon waves, waves on a pebble beach then ultimately add more base to emulate big angry waves on a beach.There is no way to change the sounds other than what I've already mentioned. If they ever decide to alter the ocean category, I'd have to buy another machine. Oh well, dems da breaks.I'll update this review after I receive and use unit #3.OK, unit #3 arrived today. It's operating perfectly. No feedback sounds, no bzzt sound when you plug it in, on/off button works flawlessly. Even the sound loops are better. For example, the ocean category isn't super base sounding as on the first two machines.Moral of the story: if at first, you don't succeed... Keep contacting customer service!

The selection of sounds on this machine, sounds good played through the speaker; however more bass should be possible considering the size of the unit. I have been sleeping to various sounds on my computer for about 8 years now, so I have become particular as to my likes and dislikes. Still I think the internal sounds are good: Rain, wind, waves, brown noise with decent bass actually compared to the external sounds I played.One night after a couple months, the machine would repeatedly abruptly stop playing the sound after about 10 seconds. But it has worked fine since for an additional month.There is an external input jack and connecting cable that connects to the headphone-out 1/8" jack from an external player if you want to use your own sounds, which is nice except the bass is weak. But mostly I like it as it allows good variety. You will need to rely on batteries/external power for the external player if you are attempting that method because although this sleep machine has two USB ports for charging, the circuit produces a loud buzzing when the external input it powered from the sleep machine; but the instructions describe and warn against this.The other features such as the LED lights on the display, and the auto-shutoff times, work well. Volume has limited loudness but should be enough for most people.

I had tried cheaper machines before this that just didn’t meet expectations for one reason or another. I love this one with its variety of sounds and adjustments. Other “non repetitive” machines still bugged my ear; this one seems to actually randomize in a way that feels natural, not artificial. Also a massive kudos to the company for making it possible to turn off all the lights!
