Wax buildup and moisture are the biggest things that can cause issues with the monitors. Keeping them clean and dry will keep the IEMs in their best working condition.
To begin cleaning the IEMs, wipe down the outside of the pieces with a soft towel or microfiber rag and a bit of rubbing
alcohol. The
alcohol will break up and clean any wax or dirt on the shell and also help evaporate any excess moisture on the IEM.
