Description
The black standard cable is a replacement for the cable that comes with the Etymotic ER3SE and ER3XR. Etymotic utilizes an MMCX connector with a special “key” that helps lock the cable in place and protects the integrity of the connector. This cable may also be used with many other earphones that have MMCX connectors.
