Shure GLXD14/SM35 Wireless Headset Microphone System

This wireless system's SM35 headset microphone features a tight pickup pattern, clearly capturing your voice without picking up unwanted ambient noise.

Part of Shure's GLX-D 2.4 GHz digital wireless series, the Shure GLXD14/SM35 Headworn Wireless System combines leading-edge LINKFREQ Automatic Frequency Management technology with best-in-class intelligent lithium-ion battery recharge ability to define the standard for seamless operation and digital audio clarity.

The SM35 headset condenser microphone from Shure gives multi-instrumentalists the freedom to express themselves without having to sacrifice the sound quality found in traditional microphones. 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.
