Pros:

Variety of colors

Adaptable to many power sources

Sturdy and compact design

Comes with all the necessary cables and plugs

Cons:

Very long wait if returned for any reason

Cannot be used separately

These SoundSOUL devices are a light show water fountain device with LED sound system and four colored LED lights. It is made of acrylic which makes it very lightweight. The transparent part of the device is polished which makes it easy to watch. All the materials used are non-toxic, so you can rest assured no harm will come when you are handling these devices. The fountain of water soars higher the louder the music is playing. The four different colors LED lights dance and jump in rhythm to whatever music you are playing. It is pretty cool to watch and enjoy. It is adaptable to most kinds of iPhones, iPads, iPods, Mac, Android phones, and other audio devices. You can literally enjoy this device anywhere you are!

Color Variety LED Lights

LED lights do not burn as hot as regular lighting, so they are much more cost efficient than the others, as well as reduced risk of combustion or burning your fingers. They are also made of an epoxy lens, as opposed to glass, so it takes a lot more to break them than your regular light bulbs. Add all of these benefits to the fact that the lights in this device come in four different colors, and you will find yourself a safe, non-toxic, energy efficient form of water dancing lights. The lights dance higher as the music is played louder, so you’re never disappointed in the light and fountain display action.

Lightweight and Nice Texture

These sound systems are made of acrylic, are quite small at just 9 inches tall, and are very lightweight. All the material used in manufacturing is non-toxic so you can rest assured that you’re getting the highest quality product for the price. The transparent part of these devices is polished to a shine, making viewing an enjoyable experience. The built-in amplifiers bring a bright and clear surround sound. The benefit of having a pair of those (as these come in a set of two) ensures you’ll be hearing and watching the music from wherever you are in the room.

Cost and Value

These devices are a relatively low cost. They come with all the necessary cords and plugs. The LED lighting of the four different colors will last a very long time, and the fountains are solidly built so barring any accidents, they will be break resistant and hold the water inside for as long as you own the devices. They are great for a gift or to keep for yourself, they are compact and portable and work together very nicely. If you’re looking for an enjoyable, fun, and relaxing display, look no further. You’ve found it!

Pros:

Variety of base colors

Four vibrant LED lights

Lights bounce higher when music is louder

30-day manufacturer warranty

Portable and lightweight

Cons:

No bluetooth connect

Power cord is quite short

This is a fun, new product from e-Joy that combines the quality you’ve come to expect from the e-Joy brand with a trendy fashion of dancing water devices. This pair features 4 multi-colored LED lights that will produce a magnificent light show! The water jets dance to the beat of the music. The devices themselves measure in at 9 inches tall, and are compatible with any device that has a 3.5 mm audio jack connection, including your iPhone, iPad, iPod, PC, Mac, MP3 or MP 4, home computer, or Android device.

Compatible with Many Audio Devices

One of the great things about these systems is that they are compatible with many devices to which you have easy access. If you have a 3.5 mm audio jack, this pair will be a delight. You can connect them to your headphones and enjoy their water play while being the only one listening, or you can hook them up to your iPhone, iPad, iPod, PC, Mac, MP3, 4, and 5, your PC, Samsung, or Android device.

Variety of Colored LED Lights

This pair comes in a set of two and each one has 4 different colored LED lights to perform at maximum enjoyment to the beat of whichever music you choose. The colored lights dance and bounce in the water, jumping higher as the music plays more loudly. Having the option of plugging into several outlets gives you the freedom of keeping them together, or placing them apart from each other in order for your whole party to enjoy them. It is mesmerizing to watch the colored lights move in sync with the music and each other.

Cost and Value

These ones are a little on the steep end of the price spectrum, compared to some of the others on this list. However, you get the e-Joy brand name, a variety of base colors, high quality LED lights and good quality system. When you look at the big picture I think this is one of the best water systems out there. Cheap is not always better and in this case I think you’d be better off by spending a little more up front. These play loudly, have a vivid, sharp image and will not disappoint when you want to pound that bass.

If for any quality reason, you are not completely satisfied with this product you can return it for either a replacement product or a full refund of your purchase. I always appreciate a money-back warranty!

Sleek 3-Dimensional Design

Just looking at this device without them performing is pleasing to the eye! They are tall and slender in a glossy black, 3-dimensional design which is quite appealing. The first color you’ll see when they start dancing is a beautifully contrasted electric blue. Accent colors are yellow, green, and purple, and they all bounce and dance to the beat and volume level of your music. Very classy design and nicely put together to give you the optimal performance and sound.

Cost and Value

These devices will be some of the most eye-pleasing speakers you’ll own. The lights dance higher and faster with the volume of the music and have an incredible 3D light show. The cost is very reasonable and the 12-month quality related warranty seals the deal for me. I appreciate a company who is willing to back their products and seeing this warranty provides me with the assurance I need in order to push the purchase button. Beautiful systems at the right price and a warranty. Hurry and get yours before I buy the last set!

Pros:

Bluetooth compatible

Wide variety of glittery lights

Oblong display box

Good sound from the speaker

Cons:

Sound is a little scratchy

Requires a lithium ion battery for use

This set of speakers caught my eye because they are a slightly different shape from most the rest. While all the others in this list have been rectangular in shape, with slight variations in the dancing light box, these are more cone-shaped and round on the top. Still a black speaker box which seems to be the norm, but the top display is clear and round so as to push all the colors together at the top, making a more vibrant and impressive light show.

Compatible With Several Devices

These systems are also a little bit taller than most on this list, coming in at almost 10 inches tall. They are Bluetooth compatible and will also connect to anything that has a 3.5 mm audio input jack, including all types of cell phones, iPads, MP players, and computers. It has just a small cord so will need to set quite close to whichever device you choose to use. It does require one lithium-ion battery for proper use.

Full Range of Light Display

The clear display box allows for the light show to be viewed from any angle. The lights will dance the highest when the volume is louder, so be aware of that. You will need to set these in a room or office that allows the music to be loud enough to watch the water fountain display. The variety of colors and the oblong display box will create a vivid color light show that will please all.

Cost and Value

These devices settle right about in the middle of the price chart on this list. They do have some perks that make them worth a little more money and have seemingly few problems in shipping, so that helps make them worth the money. They seem to last a long time when used properly and will be a purchase to be pleased with for years to come.

Criteria Used for Evaluation

Effectiveness

There are several things to consider before making this purchase. We will discuss several of these things in more detail, but you do need to be aware of the size, sound, volume, and purpose of these devices. If you’re looking to play for the house or entertain a large crowd, you may want to keep looking. These small, portable ones are made more for your personal enjoyment and for the few people who may enter your space. They are meant to be fascinating, relaxing, and enjoyable. They likely will not blast the windows in your room. Let’s look into some of the specifics here.

Application

These are ideally set up next to your computer or on a shelf for your entertainment. They are small and compact but provide a fancy and modern feel for your room. They would be perfect in an office setting, in a bedroom, or kitchen. Remember that they are small and will not shake the windows in your house, so don’t be shocked at that. The water lights will bounce higher when the music is played louder, but typically you will still be able to talk to each other over the sound.

Sound Quality

Most of these speakers have the LED light display set up in direct correlation with the volume of the music. If you are in a library or somewhere that needs to be relatively quiet, you may not get the maximum viewing from the dancing lights. If you are somewhere that the music can be played a little more loudly you will be more pleased with the dancing lights. You do need to consider all of those places before making your purchase.

Connectivity

In this day and age, most people will be able to sync with a Bluetooth compatible device. That is ideal and will allow you the best, most uninterrupted music and play available. However, if that is not an option for you, you will need to make sure you have the proper audio connection jack. Most of these connect with a 3.5 mm jack and is quite standard for most types of cell phones, music players, computers, and laptops.

Power Source

While it is easy (and mostly safe) to assume that the system will be charged by whichever device you have them attached, that is not always the case! Some of them require a separate plug-in for the wall, while some require a battery. Please be aware of these requirements as well, whether using for your own or giving as a gift, as you will want to plan accordingly and have all the items needed in order to start the music play and water fountain show quickly and easily.

It's all about that Bass!

In order for the lights to dance around and give a proper show, it needs to a good frequency to feed off of. Make sure that you always check the quality of the sound before purchasing. No matter how pretty the speaker may look, if it doesn't sound good, then it won't work right right either.

Other Factors to Consider

Size

The size of the dancing water systems is a factor that you need to take into consideration, especially if you need something that is portable. Most are smaller and designed to link up to your computer, tablet, or phone, but there are some that are bigger and meant to stay stationary. Be sure to check out the size before purchasing to make sure that it meets your needs.
