The PTT A4M Push-to-Talk Hand Mic from Telex is a compact microphone designed for voice paging applications. The ergonomic design fits comfortably in the hand, and there is a large push-to-talk button for activation. The dynamic mic capsule has a noise-canceling design that's perfect for use in noisy environments. It also offers excellent voice response characteristics for high-quality performance in quiet areas as well. The mic has a coiled cable that can stretch from 1.5 to 6 feet to minimize tangles.
