Know next to nothing about iems, truth be told. I'd need a reasonably cheap, robust, with detachable cable and small profile earplugs iem. Plenty of these online, but I'd ofc. like something that doesn't sound like shit. Would buy one for myself and one for gf. We've been using waterline re400, those things sound amazing, but are really poorly built. I don't know what she does to them, eat them I guess (she even managed to kill rha-ma750, and that's made of steel and thick rubber), but even my broke after some time, and I do take care of them. Thanks.
