Hello all! My band is transitioning to an IEM system for live shows. This is a daunting new world for me... as I really haven't had any experience in it. I picked up a set of Shure SE215s, and a set of cheap six driver amazon special earbuds. I like how the Shure earbuds fit my ears, but they don't allow for a lot of headroom for volume. The cheap amazon ones sound better and have more headroom, but I don't care for their form factor. Shy of dropping $1k on a set of custom moulded earbuds, is there any particular earphones that you guys might recommend in the $600 and under price range? I'm sure that I will eventually get a set of custom ear moulds done, but at the moment, but wallet will not allow for the expenditure. Any advise on models is greatly appreciated!
