System-S 4-pole 3.5 mm jack to 3.5 mm jack Stereo Audio AUX cable Headset Extension Male to Female Jack cable jack to jack 110cm does what it is and looks quite good. I have chosen the red so I can distinguish the better cables. All in all, I'm using the System-S 4-pole 3.5 mm jack to 3.5 mm jack extension 110 cm very satisfied.
