The BLX Wireless Headset System from Shure joins world-class design and construction with simple and easy setup and operation, featuring QuickScan frequency selection and the durable SM35 headset condenser microphone which gives multi-instrumentalists the freedom to express themselves without having to sacrifice the sound quality found in traditional microphones.

The new SM35 headset condenser microphone from Shure features a tight, unidirectional (cardioid) pickup pattern provides excellent rejection of off-axis sound sources to prevent feedback and signal bleed for superior performance on stage. Standard TA4F (TQG) connectivity seamlessly integrates into any Shure wireless bodypack system, and its availability in a number of bundled systems makes it appropriate for any stage, ranging from small clubs to large installations and arena tours.
