I connected these from dvd and ps3 to my surround sound and can tell a little difference in sound quality. I have a broader range of frequencies now. It doesn't make the audio any faster or louder, just a little clearer and higher and lower frequencies through. And at the price here they were cheaper than a/v cables. Great value overall.
Great little accessory. My new car had a plug for my Ipod and this makes it easy to carry my music with me. The retractor works fine, so there are not wires hanging down in the way of the other controls.
