While the plug fits into the ear cups of my ATH, the pins do not touch unless the plug is inserted and held. Once you let go, it slips out just enough not to transmit a signal. However, despite the fact that the description says it's suitable for headphones, it doesn't claim to be my particular model, so I won't give it more than one star. With open ports, like a laptop or phone, it works fine. With sufficient connection there is no noticeable drop in quality and the cable appears to be quite durable.
