The sound quality is good when the headphone set is expanded for listening. BUT - it does not extend the microphone on the headset microphone + headphones. The connector does not have the 3rd pin which is needed to send the microphone signal to the device. See attached picture. On the left is a headphone jack with a microphone. Notice the extra black ring on the plug compared to this Kinps extension cord connector on the right. I've tried - my Macbook doesn't recognize the microphone in my headphones when I use an extension cord, but it does when I plug the headphones directly into my computer. The list here should make that clear. I will buy one again that supports my headset/microphone.
