Shure MX395B/BI Microflex Miniature Boundary Microphone

MX395B/BI Microflex Miniature Boundary Microphone description:

The Shure MX395B/BI Microflex Miniature Boundary Microphone, Bidirectional, Black with 3-pin XLR connector. A discreet and stylish boundary mic that delivers exceptional sound quality.

The Shure MX395B/BI Microflex Low Profile Boundary microphone is an ideal table microphone when minimal presence is of high priority. Perfect for meeting rooms, MX395 microphones deliver exceptional sound pickup whilst barely being noticed. This surface mount MX395B/BI model features a Bidirectional polar pattern, a Black finish and a 3-pin XLR connector. Microflex microphones include the highest standard of quality and efficiency for installed audio applications. All models offer Shure CommShield Technology, which guards against unwanted radio interference from consumer wireless devices such as cell phones and PDA’s.
