Depending on the size of stage/band, Flares® JET would be suitable for monitoring use. They provide good isolation, using the same principal as our Isolate® earplugs. The isolation in the Flares® JET 2 & Flares® JET 3 is better as JET 2 is made from aluminium and JET 3 is made from titanium grade 5. If you’re a professional artist and use IEMs on a regular basis, we would recommend the Flares® PRO. They have the best sound isolation and are more detailed which will give you a clearer mix.
