These speakers are good for the price due to the fact that they are, USB powered, slim and portable, and have decent sound quality. However, there are speakers out there in the same price range that offer better sound quality. While some of these might not be as portable they are still USB powered. They're great if you want to travel with them, and need some speakers to set up in your hotel room. If you are looking for a True USB speaker set up to use at your home and aren't as concerned about it being portable, then I would go with other choices out there in the same range. I usually use the standard AC plug with AMP that plug into your computer's headphone jack, but my jack was damaged and must settle for the less powerful USB type.

If you need USB connector type speakers, look no further. These are a great sounding pair. I bought these for my new laptop because the headphone/speaker input was in the front which I didn't care for. Just plug into any USB port and the computer will install the drivers for it (Windows Vista). Sit back and relax to your favorite music. Volume is very LOUD so I had to turn it down a bit. A very good value for the monry.

The sound is pretty good, easy connectivity with my Vista ultraportable. I have mostly design quibbles. Don't understand their size - too big for their innards! In their travel case they could easily pass off as a netbook computer! Could have been half as big and therefore lighter with the same 2-way configuration. Designer or boss doesn't seem to understand the value of size/weight in mobile speakers. Plus no channel in back to feed the cables through, so when packed up in their travelling case the cables are compressed by the closed kickstand which itself will wobble and eventually loosen at hinge due to this oversight. Aesthetically they're ok, yet don't you hate fake bass ports? Like a fake air intake on a car hood. I mean who are you fooling? Just because you're selling them online doesn't mean you can play that game! Just more useless molded plastic, more weight... keep it simple, guys! Stick to the basics, less is more, less is more... On the up side, one design decision which I do agree with is the avoidance of any front-facing power-on LED indicator. These are invariably too bright in a darkened environment and an eyesore when watching a DVD, with a pinpoint of bright blue light staring at you from off to one side of the screen. Here the solution was to place a column of light on the side, which both softens the effect and does not intrude on the visual field.

These USB-powered speakers are well-made and powerful enough to fill a small room. They have no battery and no aux input and work only plugged into a computer USB port. They sound quite clear on voice but tend to be boxy and shrill on rock, better on acoustic stuff. Clearly they're intended for casual use, especially to travel in a suitcase. If you place these on a desktop with the little 2" drivers pointed at your face 2 ft away, they are so hot as to be virtually unlistenable; tilting them back 45 degrees (or more) mellowed them out a bit... The bass is surprising given their small size- I don't doubt their claimed response of 80Hz. The headphone output is excellent but the very short, captive cords are a pain. I'm using them with a USB extension cord.

After 30 days of use I gotta say these a fine value. A little judicious equalization via iTunes helps: a few dB of boost at 60Hz gives them much-needed weight without causing them to overload; -5dB at 4k takes out the screech. Not bad. The headphone output is actually quite good, a little wooly in the bass but decently flat from there up and it drives my Sennheisers LOUD.

I bought this in 2011 to use with a Windows laptop/notebook purchased new in 2007.

It would not work.

I emailed the company, sent screen prints from my computer, and they were of no help.

All I got from Cyber Acoustics was an cc of an email between Cyber Acoustics employees commenting that "It looks like he doesn't have the drivers he needs."

When I asked about how to get the drivers - they simply said they don't supply them.

Well of course the service on my laptop was now in a pay per use status because 4 years old was ancient. Microsoft was no help.

I held on to the speakers and when I purchased a new laptop very recently plugged them in and...... THEY WORKED!

So okay, they work. But not stellar quality. As I have mentioned in another review of a speaker type item, I am not an strict audiophile. I don't like static and the purpose of the purchase was to improve upon the poor speaker quality on my 2007 laptop.

Well, if these speaker had worked on that laptop it certainly would have been an improvement on the laptop's speakers, however my new, W7 laptop sounds the same as these speakers. The only advantage is these speakers can go a bit louder than the laptop.

Base is not good on the laptop or on these speakers.

Thumb-up if you can get them to work.
If you can't - don't count on Cyber Acoustics for much support.

These are a great set of speakers. They are USB powered which is very convenient. The USB connection is ideal length for plugging into a laptop. I bought these for use with my PC. I bought a USB extension and plugged them into the back of my PC. The speakers powered up right away with no problem. There is enough wire length between R and L so I can space them on my desk. There is a mute button, volume up and down buttons (in case you don't want to use your player volume control) and an input for ear buds. The speakers shut down external sound when the ear buds are connected. Don't expect Bose quality sound but for the size, they have very acceptable sound quality. I like these enough that I have bought a set for my son and for my daughter-in-law for their laptops as a Christmas present. They come with a very convenient carrying case that you can either pack or carry when going on trips. All in all, I'm very pleased with this purchase and I recommend them either for laptop or PC use. For the price, you can't go wrong.
