Shure MX395AL/BI

The Microflex™ Low Profile Boundary microphone is an ideal table microphone when minimal presence is of high priority. Perfect for meeting rooms, these microphones deliver exceptional sound pickup while barely being noticed. Bidirectional pickup pattern is ideal for capturing speakers from both sides of a conference table.
