The order was delivered quickly. But the extension is the extension looks allerletzte.Die wertig from the cable and the gold Connectors and even the connector is screwed. But what good is it if the Eigent metallic full bib. In short, I needed a Velängerung and ordered this because my earphone cord was too short. So cable into the socket and plug in the Ipod and then mixed play and then what ... it sounded like Hall and Church effect. On my HIFIDELIO the same and I thought something wrong, Cable is not in place or so NO extension was the problem. Unplugged and re-plugged and everything was great with no extension. So once bought more electronic waste. Look around elsewhere. Incidentally, my headphones are the Audio-Technica ATH-M50.
