Shure 512 Headset Microphone - The 512 microphone was designed for sports and news announcing, intercommunications systems and special events remote broadcasting.

The 512 microphone was designed for sports and news announcing, intercommunications systems and special events remote broadcasting. It offers convenient hands-free operation and a lightweight frame to reduce user fatigue. The unidirectional pickup pattern reduces unwanted background noise, permitting its use in noisy environments. The microphone characteristics are tightly controlled resulting in consistent response and output and the headphone response is tailored to enhance voice intelligibility.

The headband easily adjusts to fit a variety of head sizes and hairstyles, and the microphone boom can be adjusted to accurately place the microphone cartridge at the corner of the user's mouth. The microphone is supplied with a foam windscreen to reduce explosive "popping" sounds and a cable clip to secure the cable to clothing.
