Review on Monoprice 6ft 3.5mm Stereo Plug/Jack M/F Cable - Black: Reliable Audio Extension with 6ft Length by Kristy Young

As others have said here they make a lot of noise. I tried using them to increase the number of PC speaker ports on my desk (large desk and 32" monitor). I moved them away from power cords but still picked up noise/interference. I have NEVER had a problem with Monoprice. product so it will definitely never put me off buying from them again. I just wanted to warn anyone thinking of using them to get the shielded version that Monoprice is offering. Monoprice's shielded versions are gold plated so you can tell the difference. As with the other poster here, I may have waited too long to get them back.
