OVERVIEW
The cardioid polar-patterned Core 4288 offers a 4 dB increase in dynamic range and a 14 dB decrease in THD (total harmonic distortion) over the Legacy version and is ergonomically designed to fit comfortably. It easily adjusts to fit any ear size and head shape, while at the same time, it mounts securely and is hardly visible. By rotating the boom and the ear hook, the microphone can be used on either the left or the right ear. In addition, the connector splits the cable from the microphone boom allowing you to swap broken cables and/or transmitter connectors quickly.
