Perfect for electronic music shows and probably fun for little kids too

These glasses create great visuals when looking at light through them. They are also very lightweight while still staying on your face comfortably. A lot of the other diffraction glasses have reviews that complain about them being too heavy and still seeming to feel kind of cheap. These are neither heavy nor cheap feeling. I got white ones and used blue-light responsive glow paint to design them. Good for dancing at electronic shows, and probably cool for little kids as well.

Well worth the low price point. No need to spend 20+ dollars.

I got these for my 5 year old daughter and (mainly) my 2 month old daughter. My 5 year old loves music and wants to play every instrument, so I figured I would pick these up and let her play with them until her sister is old enough to use them herself, at which time my oldest can teacher her how to do it. They're small, perfect for kids' hands, and they sound great. No complaints.
I received this at a discount in exchange for my honest review.

Bought two, one for a 10 year old and one for a 6 year old.  They love them and can finally play their iPod music for the world!  Well, at least for those in their rooms?  : )  Products come in a protective black bag and charge easily with indication lights (need to be charged before using).  Seem to be of good quality for $20.  Sturdy and small enough to take with.  The fact that they can be charged and don't need batteries is a HUGE plus in my book.  Would recommend to others.

If you're getting this album for kids, it's perfect. there is piano mixed with electronic (and by electronic I mean more electric keyboard and computer-based sounds) mixed with jingle bells and stuff. the kids respond so well to it. Not great for teens though... feels a little childish for them.

I know this may seem a little pricey ($40 ish) for a kids gift, but I have found it is completely worth it.  It comes with a mic and flashing disco lights.  My eight year old figured out how to use it before I pulled the directions out.  Ease of use is a big deal because I want this to be a basement toy.  My kids play with it for hours and even use it as a cd player when they want music, but don't want to sign along.  It was the center of the last sleepover party and the kids really enjoyed singing along to songs.

Arrived when expected and as expected.  I would definitely recommend this.

These mp3 players are diminutive and as simple to operate as is possible. Children will love them, adults will love the price, and everyone will recognize the nearly ubiquitous SpongeBob branding.

We ordered 4 and all of them worked right out of the box, loaded up easily, charged to capacity and began delivering their music.

The only complaint I could make would be that they are NOT loud, in fact, they are quite quiet, and I'm torn: is this intentional so as to insure that children don't damage their hearing by listening to music too loudly? Or does the unit simply lack the power to push the volume out?

I guess it all depends on how you want to look at it.

Based on my daughter's delightful squeals and need to play with this at least a few times a week, I'm giving it 5 stars. She loves to pretend she's singing on a stage (top of the stairs), and this fits in her hand like a real microphone. The MP3 sound quality isn't exactly crystal clear, but my kid doesn't care. **fyi, If you pull out the little tab inside the MP3 cord compartment, the buttons will play the songs in their entirety--I had to go online to figure out why at first it only played 10-seconds of the songs.

I bought this for my niece when she turned 5, and she absolutely loves it.
Very easy to use (not for me, but im not a kid), and she has fun listening
to the sound effects when skiping tracks. I bought the 512MB version cuz I don't think a kid knows that many songs, and it seems to be enough. It's a great first gadget for young kids and it gives them confidence around technology, which I like. She normally uses the speaker, and the sound it's alright for a low cost mp3, and I don't have to worry about headphones and the hearing damage, bla bla bla.
I do recommend this, its a nice looking product, easy to use, worth the money.

I got this for my kid's birthday party.
Setup was super easy, the Party Rocker paired first time with my iPhone for wireless music streaming.
The disco lights are very bright and visible even in a well-lit room.
Sound quality is also very good with lots of volume and bass.

These are awesome!  I go to a lot of EDM shows and festivals.  These allow me to enjoy the music clearly without all the ringing the next day.

Works great with earphones.  If earphones unplugged, it will sometimes skip in the middle of a song.  We purchased 3 for our kids and they all do the same thing.  Called the company and they said we had downloaded a song with a virus.  They know you are not going to be able to go back through 6 hours of songs and check each song.
Kids are happy with product and use it all the time.  I think it is worth the $30 we paid.  Big enough for kids not to lose.  Really easy to use.  Loved that you have speakers to share songs with friends and pretty good sound.  Definitely for kids.

Our kids love these so much we had to buy another pair for our younger child. They are cushy and comfortable for little ears, and fit our 5yo and 2yo perfectly. The length of the cord is good for cars and sharing. Easy to adjust and has a port on either ear so you can share without a splitter (but we found a splitter was helpful in the car just so one kid's ears aren't being pulled on by the other kid.) I think the volume control works on some devices but other devices like our boombox my oldest can turn it up really loud and will, so be aware of that. They are durable and have lasted many months on long car rides and plane trips. My kids love to listen to music and kid podcasts.

I can't help but view this product as more of a toy than an instrument, but it is still oh so much fun. Turned quite a lot of heads walking around town jammin' on this thing and even met a few rappers while making beats.

What more can I say about this product? Fat 8-bit sounds that take you back to your childhood and a pretty cool and very easy to use sequencer. Teenage Engineering leads the industry in creating electronic music instrument layouts, and their genius is shown wonderfully in their Pocket Operater series, especially this Arcade

I love this little thing, with TONS of sound for the price and size.  My 12 year old daughter got one for Christmas, after I saw and heard what hers could do, I ordered 4 more, in different colors for each person in the house.  The great thing about these little things are you can plug them in to a wall for power or charge them and carry them around.  I also purchased memory cards for each.  Loaded music, radio mystery stories and books on them.  So NOW, when I am working in the yard I can listen and as I move on to the side of the house which has no elec, no problem.  My husband uses his in the garage working on the cars, the kids will use them as mp3 players in their pockets, but when they get around their friends, they just pulled their earphones out and everyone can listen.  Then their friends are shocked at the level of sound.  The lights are pretty nice also.  A lot of BANG for under $15 dollars.  Depending on the color you purchase, dictates the price. I have the green, silver, black, red and pink.
I have been contacted a number of times on how to attach the waistlet.  So I have added pictures on how to add the waistlet, I hope this helps? IF not, contact me and I will see what I can do.

Saw this in a store one day and thought it would be ideal for my four month old daughter since she loved lights and music.  Sure enough any time she gets pouty I would whip out this musical toy and she would be entranced and try to baby talk with it. Nice feature to be able to turn the music off and only be in glow mode if you were to take this in a church or social setting.  The velcro backing reveals a switch to enable an OFF/sample mode, full music/light mode and light only mode.  Along with a squeaking mouse doctor toy and a dancing elmo this is her favorite toy.  The music are instrumental variations of about 6~7 different lullabies and they play for a couple of minutes shortly after which the face light will dim down.

My mother gave 2 of  these to both of my children and both love them.  My daughter (23) is using hers as a make up table using the cd holder for her hair appliances.  My son (18) is using his for all of his electronic music production equipment and it was a great size for his launchpad, midi controller and keyboard.  They were easy to put together and my Daughter put hers together herself.  The size is compact enough to fit into many smaller settings.

The construction was sturdy and didn't tweak or wobble and the wheels move easily over hardwood or carpet.  I haven't heard any complaints, but we have only had them since Christmas so I can't speak to the longevity of the product.  For the price and the versatile size, I highly recommend giving these a try.

At the time I'm writing this, i've been playing various electronic songs which really test to see how good a sub is. It's exceptional. For the size of these speakers and sub, plus the price, this set is an instant winner unless you are unfortunate enough to get a dud set.

Here's the layout.
Anything that has a headphone port (mp3 player, boombox, and a computer) is plugged into the subwoofer with the green plug. The sub is plugged into a power outlet. The speakers are connected to the sub. You control the volume, plus turn the system on and off, with the little disk-like thing in the picture that also has a headphone and microphone jack. So you don't even need an auxiliary cord as far as i can tell.

I have yet to use it on a tv. Mine is an old sanyo that I can't see this system connecting to. Seeing as there are no headphone jacks or really any output jacks that fit the sub's plugs, I'll have to get creative and see if i can use adapters to make it work.

Still, I have a load of respect for these speakers being so good yet incredibly cheap. Someone listening to this system thumping loader than their boombox will ask you for the price, and be wonderfully awed when you tell them it's just below 30 dollars. Have I mentioned that it's rather easy to move around? I already love this system and i'm sure you can get away with buying a separate set for everything.
