JBL PARTY BOX WIRELESS MIC AM Wireless Microphones for JBL PartyBox SpeakersThe cardioid pickup pattern of these mics deliver a warm, clear, and crisp vocal sound that's designed to make everyone sound their best over any JBL PartyBox. A shock mount system minimizes the sound of the mics passing from one hand to another, while a built in pop filter eliminates any extraneous breathing sounds that you don't want to be part of your performance. Just plug in and start singing. It's really that simple. Specifications Carrier
