I have been using custom molded westone filters for years and they’ve saved my ears, but they do make conventional monitoring a little different for me. Thinking about getting into IEM, but don’t know what equipment I need besides the ear plugs and a pack to wear on my back? For the experienced users, Is there any proprietary technology involved where brand or designs matter? I don’t have an active band right now, but is it easy to reuse the same IEMS no matter what kinds the other members are using? I’m using shure wireless for my bass, would this present a conflict? Thanks.
