The information read like a good cable, it looked like a good cable, it felt like a good cable, but when I plugged it into my headphones and guitar amplifier, only the left channel worked. The plug/socket connections were solid but a slight wiggling of one end of the cable would bring up the right channel then it would disappear again. I tried two other cables I had on hand and both worked perfectly so I was confident it was not the phones or amp at fault. I know things can go wron,g but really? What sort of quality control does it take to ensure three wires are securely connected to two plugs? I cannot remember ever buying a cable before that was faulty from purchase. However, I returned the cable to Amazon and had a refund the next day ... and THAT is why I shop so much with Amazon!
