Etymotic CBL-ER2 ER2 Replacement Cable

The ER2 Standard Replacement cable is the blue standard cable replacement for the cable that comes with the Etymotic ER2SE and ER2XR. 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.
