The d:fine headsets are offered in single- or dual-ear mounts to cover a broad range of applications. They come in several colors, two different patterns, and with different boom designs and lengths to match the various applications. The ear mounts will fit any head and ear size while the short boom is for louder speakers or situations where the mic needs to be less obtrusive.
The omni headset microphones are for situations where a broad pickup pattern is essential and off-axis noise is not a problem. The directional versions offer maximum side rejection and excellent sonic focus on the subject.
