Cleaning MMCX connectors
The following cleaning tip is applicable to all MMCX connector in ear monitors (Shure, UE and Westone):
This tip is for those hearing an intermittent drop off of sound from one or both IEMs. Also, I have found it is a good idea every couple of months to clean the connectors to insure optimal performance. You will need DeoxIT D100L Red and DeoxIT Gold (both are available from Amazon) as well as some tissue paper and a couple of toothpicks. Put a small amount of DeoxIT Red on the tissue paper wrapped around a toothpick and gently insert it into the ends of the IEM and cable and twist to clean the connector. Then repeat this with the DeoxIT Gold. Let them dry for 30 minutes or so and reconnect the cable to the IEM and you are finished.
