Noise in Speakers

I have a pair of QFX cs-60 multimedia usb speakers. They make an annoying fuzz sound but it isn't always loud. The noise also isn't loud at all when I'm just on the desktop unless I make a big highlight box (when you left click and drag). The bigger I make the box the louder the noise gets. It is very weird. The static buzzing-like noise also occurs when the speakers are turned all the way down, but not off. The speakers work fine, I just want to get rid of the background noise that they make if I can.
 
Actually sadly enough I just figured out the problem. I am not that good with computers or technology in general and remembered my computer only has two 2.0 USB ports in the back and so I had to plug the speakers into the 3.0 port. I switched them over to the 2.0 and it fixed the noise. I am kind of embarrassed actually lol, but you can either keep this thread up for people to use it as a reference or you can delete it. Thanks anyway to anyone who would have tried to help =)
 
The USB power supply in a PC is notoriously noisy. So-called "USB speakers", whether they only draw power from USB, or also have a USB sound card integrated, generally are just "noisy", and not recommended. But that's why they are the cheapest speakers around.
 
Last update. It actually wasn't the 3.0 ports that was making the noise. I still don't know what was causing the problem because I tried all of the other USB ports, because I have OCD and didn't want the speakers USB plugged into the top of my PC but into the back, and the background noise only stops in one particular USB port. I have no idea why but I have a Dell XPS 8700 and the noise only stops when plugged into the top left 2.0 USB port.

Yea, I am not good with computers and stuff so I did not know that. Thank you though. Also these speakers were extremely hard for me to find I guess that is why, but I really wanted these because I didn't want to have to plug them into the wall or into my power strip. I really have OCD =/
 
USB speakers are pretty common, IME, but I work in an office. If you want some assurance of quietness, power should come from the same power strip as the PC, but the PC used only as a data transport (IE, to a USB, S/PDIF, or TOSLINK DAC).

Your audio signal can, with good speakers, be down in the several hundred microvolts, and still audible. 1-2mV is going to be audible with anything but the worst of the worst, if it makes its way into the midrange. USB effectively allows tens to a couple hundred mV of ripple. Good USB audio devices have a substantial portion of their design put into cleaning that up. Some do it better than others, but on some PCs, it might just be too much to handle.

Without using battery-powered speakers, USB quality for powering them will be a luck of the draw kind of thing.

Considering the OCD thing, do you have a problem with using a monitor with integrated speakers, or a sound bar on a monitor that has sufficient support for one?

I kind of wanted speakers that had it's own power/volume control. I guess I wouldn't really mind if the monitor had it's own speakers or even a sound bar but I also don't have the money to get a new one. I just recently (2 weeks or so) bought this PC and monitor and all the other accessories.

Show me the reseller item and specs for these USB speakers.

Is any part of those speakers powered from an AC wall connection -- even if it goes through a surge and noise suppressor?
