I didn't think a white noise machine was necessary before having a baby, but after 2.5 months, it has greatly improved my son's sleep quality. The machine has different pitches of white noise and peaceful sounds, with great sound quality and volume, making it perfect for travel. I will continue to use it even after my kids no longer need it.

I am extremely impressed with the portability and effectiveness of this little noise machine. I travel frequently and often struggle to fall asleep in noisy, remote areas. This device is surprisingly loud, so much so that I can't even use it on the highest setting next to my bed. I was initially concerned that it wouldn't be loud enough, but my worries were unfounded. I do wish it was battery operated, but I found that it hardly used any power when I ran it off of a power bank overnight. I also use it at home, and I appreciate the variety of sounds it offers. Its compact size makes it incredibly easy to pack in my carry-on bag.

The sound machine automatically saves your tone and volume settings, which is convenient. The power jack is located on the rear of the unit, making it harder to hide. It does not have battery power or backup. The brightness control for the light is a bit confusing, but once you figure it out, you might not need to adjust it often. You can also turn off the timer/sleep LEDs by holding the timer button for a few seconds if they bother you.

The WN machine is stylish and has sturdy, large buttons. It has 36 typical sounds and can get fairly loud. It uses a small insertion plug instead of USB-C and has a variable color nightlight at the bottom.

My son has been using a fan for white noise to sleep since he was a baby. Now that it's getting colder, I decided to get a sound machine and this one works really well. I appreciate that it's compact and easy to take with us wherever we go.

This sound machine offers a wide variety of tracks, including different types of natural sounds, music, and relaxation sounds. It can reach a volume of 67dBA at the loudest setting, and has an auto-off timer with options ranging from continuous to 4 hours. The device comes with a 59 USB power cable and AC plug, and has a night light LED on the bottom that can be left on or turned off, with 12 different LED color options. The speaker is encased in a soft cloth-like material and has buttons on top. It is compact in size, measuring 4 1/4 in diameter and 2 1/4 in height, with a translucent bottom to allow the LED lights to shine through.

I absolutely love this sound machine. It's compact and perfect for travel, and can be easily carried. It offers a variety of sounds, but my favorite is the one that resembles white noise or an air conditioner. It has been extremely helpful for both me and my dog to sleep better. I am incredibly satisfied with the product and feel that it is worth the price. Overall, it's a great deal.

The sound machine was good, but I wish there were more sound options to choose from.
