Sennheiser XSW Mic

The XSW 2-835-A Wireless Handheld Microphone System with e835 Capsule (A: 548 to 572 MHz) features a true diversity receiver, and a handheld transmitter with an intuitive LCD display. It has 12 compatible channels and is offered as an easy to use, all-in-one wireless system for singers and presenters.

The unit has automatic frequency management and synchronization so you don't have to scramble to find an available channel. The transmitter's e835 capsule uses a cardioid polar pattern, which is part of the evolution series and designed for withstanding tougher, live-stage conditions.
