Our microphones come in three subsections: Standard, Noise cancelling & Super Noise Cancelling. They are made of robust 8mm brass and come on a sprung steel flexible shaft with a durable black finish. They are designed for continual heavy usage, utilising the solid brass head/mounting & M10 stud. The standard lengths are 300, 400 and 500mm length. We can customise the length and finish, whatever the customers requirements. They have been used in a diverse range of applications, including: Radio, Telecoms, Transport, Command & Control & Dealing rooms.
