||The Shure PSM200 lets you start with a wired in ear monitor system - and you can upgrade it to wireless later! The Shure P2R215CL is a version of the Shure PSM200 provides the same incredible sound quality, isolation and reliability as are found in the wireless version - with an ever sweeter price tag. Shure's P2R hybrid receiver pack includes a built-in limiter, and a 1/4 inch line input jack. The included ear phones are comfortable, light in weight, very effective in isolating against outside noises, and provide high fidelity sound. Get In Ear from here.
