I'm no technician, and some of the reviews here made me quite skeptical of this piece of equipment . . . so for those of you out there who, like me, just want to know if these things work, they do.  They work perfectly.  I received mine (2 of them) today and promptly plugged them in to see if both ends of each splitter played full audio.  I have just the track to test this out; one with audio going back and forth between left and right channels.  Testing this out in every case, I could hear both left and right channels through my headphones, just as I would have hoped.  This tells me that the item is NOT simply channeling the left audio into one end and the right audio into the other end, but sending a "stereo" signal into both ends of the splitter.  Also, the plugs fit and "seat" nicely, so I'm confident there will be a good quality and consistant sound coming through when it's time to put them to good use.  Though the price is incredibly low, you can purchase with confidence!  Oh, and in case it sounds like I work for Belkin or for the company selling this product, nope, I just wanted to clarify the issue since I was so confused reading so many reviews saying two different things.  Now that I have mine, there's no confusion here!
