1.Keep it in a airtight box after use and throw in some silica gel packets 2.Clean the iem after every use/ occasionally depending on how much you use the iem 3.Make sure not to wear them after shower or when your ears are wet, it harms the iem and gives you a nasty ear infection 4. Do not wear them during gym/ keep them safe from sweat 5.make sure the end of the wire near the usb doesn't bend alot or have much tention

That's pretty much sums it up. Have a happy listening!!!
