Deliver dependable voice pickup when clarity matters most. The Shure SM39-TQG is a wired, on-ear headworn microphone designed for presenters, instructors, and performers who need stable placement and consistent speech intelligibility. Its cardioid polar pattern helps isolate the primary voice from surrounding noise, making it a strong fit for environments where ambient sound can compete with the message. With a sensitivity of -47.2 dBV/Pa, this microphone is tuned for articulate vocal capture without forcing the system to work harder than necessary. The headworn format keeps the capsule positioned close to the source, helping maintain level consistency as the speaker turns or moves. That matters in real rooms, where small changes in mic placement can affect clarity, gain before feedback, and overall listener comfort. The TQG connector supports compatibility with Shure wireless bodypack systems that accept this interface, giving integrators a practical path for mobile speech applications. For organizations that value repeatable performance over disposable hardware, the SM39-TQG offers a focused, professional solution for spoken-word reinforcement.
