I've just recently bought these iem's: LD Systems | MEI 1000 G2 They sound great. It's my first time after 11 years of playing & singing through foldback speakers in a band that has 5 part harmonies. Such a relief to be able to hear myself for once. My question is I live in Queensland, Australia. The summers get quite hot and humid. <30 degrees and something like 90-100% humidity. On stage that just kills you. I want to know if there is a way to keep my earphones from falling out of my ear when I get really sweaty on stage? I'm performing at a whole bunch of gigs including 5 days at Woodford Folk Festival at the end of the year. So that's the one I mainly need it for. Thanks in advance.
