COLES Lip Microphone 4104

Coles 4104 Lip Microphone — Professional Ribbon Broadcast Mic

The 4104's noise rejection isn't a digital trick — it's precision acoustic engineering:
Lip Positioning Bar — Rests against your upper lip to lock the ribbon capsule at an exact, consistent distance, eliminating level inconsistency between takes or commentary shifts.
Proximity Effect Tuning — The mic is deliberately built with an aggressive low-frequency roll-off. At lip distance, the ribbon's natural proximity effect kicks in and perfectly restores bass warmth to your voice — while distant crowd noise loses its low-end energy and recedes into the background.
Figure-8 Polar Pattern — Bi-directional pickup rejects off-axis sound by over 30 dB, so two commentators can work side-by-side without channel bleed.
Integrated Breath Shields — Heavy-duty stainless steel nose and mouth screens eliminate plosives and breath blasts with no external foam windscreen required.
