I bought this extension to use my headphones (Sennheiser HD595) on my TV in order to be able to make the most (possible) late at night, without ch ... my neighbors or my wife. And then ... surprise! connected to the jack on the front of my amp: yuck! the sound is very average, so it is very good in my 5.1 channel output. Disappointed and skeptical, doubting the outcome, I try on the jack of my TV (Samsung HD 138 cm) and then there my ears were filled with happiness: the sound is perfect, clear, detailed, both in its TV ( of varying quality it is true according to the channels) as coming from DVD's! (I am also surprised at the high quality delivered by the TV - yet just air antenna - through its jack and previously I was using only the output chain 5.1). So now this extension is still available, folded in a corner cabinet and when I use the headset: click! and to me the joys of Dolby! Technically: contacts are perfect, without play, of farms; the cable is flexible, seems solid. Of course there must be pros upscale extensions, but this for this price quite reasonable is perfect for any fan of quality sound.
