SENNHEISER Genuine MMCX BRAIDED CABLE 4.4MM PLUG for IE300/900 This is the 700260 braided cable for the IE series, with a 4.4mm balanced plug. I purchased this to connect to my IE300, but the main unit broke down at the same time, so I only used it for a few hours. However, since it has been handled by a person, please refrain from purchasing if you are concerned. Furthermore, please understand that we cannot accept complaints or returns after the transaction is completed.
