Summary: I wanted usb speakers that had a power button. These don't. I bought them since they looked exactly like a set that was not usb, but had a power button. I took a chance, but returned them since I chose poorly. I did find usb speakers with the power on/off ability, and they are great!
Pros: What can you say about these speakers? They turn on when you turn the knob. They turn off when you turn the knob the other way. They produce sound when turned on. When turned off...they don't. Seriously folks this is just a basic pair of computer speakers so if that's all you need, these will work fine. Its all I needed so I'm happy. I'm singing that Pharrell Williams song right now. Clap along if you feel like a room without a roof..............
Summary: was looking for alittle more volume for my laptop wow fits bill perfectly love the physical on-off volume knob great sound not as tinny as other reviewers would have you believe the only thing lacking is balance slider
Cons: Sounds pretty terrible, but I wasn't looking for quality. The headphone jack is also extremely noisy so you still want to plug at the source rather than using the right speaker's jack. You get what you pay for.
Summary: Tremendous bang for the buck. I bought based on other positive reviews and am back to verify them. Great deal!
Pros: If you are looking for an inexpensive set of speakers, these are for you. These speakers have great sound for there size, can achieve very impressive volume without distortion, are small in stature so they won't clutter up your desk, and are a great price. In addition, these speakers are powered via an AC plug and NOT by USB. Thus, there is no interference for CPU and GPU processors. I've been very impressed thus far.
Cons: The sound quality won't blow your doors off, they are small speakers after all. Also, the LED is kinda bright.
Summary: If you're looking for cheap speakers, these will work. They don't sound horrible, but they don't sound good either. They'll do in a pinch, or, if you're simply not picky about audio quality. I would caution buying these if you have irresponsible people who are known to blast music loud who live among you. These baby's will probably blow pretty easily, so you may want to spend more on something a little more durable. W0rd, that's all I got.
Pros: Easy install, works, sound comes out of speakers.
