I had already bought a jack extension of the brand Philips SJM2102H model, which I was not fully satisfied (a listener on two works, hyper annoying). So I bet on this product ... The pros: + Extension of 5 meters that can stay away from the screen and move it anyway, without fear of dropping everything ... my Philips 3 meters being a little just to be comfortable. + No "tweaking" required to get sound in the two atria. + Retains sound quality (but I'm not an engineer ...) The -: - A bit expensive for a simple extension. Note: A few crackles but I can not certify that it comes from the extension rather than the DVD or my helmet. I recommend this article despite the price.
