I bought a logitech Z305 3 weeks ago and although the installation went fine, the speaker would give me intermittent popping and crackling noises when or when not sound/music is playing and when or when not software is running (yes there would be no sound playing and also no software running and the speaker would make intermittent popping and crackling noises).
Although music and sound plays clearly and when it's supposed to, (although laced with popping and crackling noises/sounds), it also sounded like the speaker was not quite at it's optimum sound quality either.
So I took the speaker back to the computer shop I bought it from - a reputable shop - and they gave me a replacement z305 2 weeks later. I still have the same problems.
My laptop is a Toshiba satellite L500D using Windows 7 64 bit and Windows 7 is constantly downloading all of the latest Windows updates. I do not have any software or hardware problems. My RAM usage is normally about 50% of 2GB of RAM.
I have not had any other problems with any other devices or system components I have or have used on my laptop. On my friends Compaq laptop using Windows Vista, the Z305 works perfectly - no popping/crackinlg noises and the sound qualiy seems to be slightly better than that played on my Toshiba laptop.
Any help would be greatly appreciated.
Thanks a lot,

Please ensure that your speaker is connected directly to your computers USB port and not in to a pass through device such as a USB hub or docking station.
I hope this helps you out.

I had noise problems with a different USB powered device (Presonus AudioBox USB) and I found that it came from the noisy power on the USB port. There are Y cables available that add the power from 2 different ports to power 1 USB device. I got my best results with an independently powered USB hub, which is not very convenient for the speaker bar.
Try attaching the Z305 to different USB ports. If you get different results (even if they are all bad) then USB power is a likely culprit.
