The 4560 CORE Binaural Headset Microphone is, in its essence, a pair of 4060 CORE Miniature Omnidirectional Microphones that are mounted on two earhooks (as known from the 4266 Flex type of headset). The microphones are a stereo pair; two handpicked 4060s, selected on sensitivity within +/-1.5 dB. The actual headset is ergonomically designed to fit comfortably and easily. It adjusts to fit any ear size and head shape while at the same time it mounts securely and is hardly visible. Foam windscreens are supplied with the microphones to secure the position in the ear and to offer some damping of wind noise.
