Addendum: Have one of the plug replaced by a self-made, so I can now CONNECTING all 3 cable to my sound card. Have also set a suitable image. Wen's interested: the plug I have "extracted" from broken headphones, the rubber rundrum removed, cleaned contacts, the cable soldered and shrink tube over it. Resistance has not changed, according to 2 decimal places exact meter compared to the gold connector (is anyway only show; on the cable kommts to, not to the connector)
