4188 Directional In-Ear Headset Mic
The 4188 Directional In-Ear Headset Microphone rejects side and background noise while creating higher separation from nearby sound sources. This improves the gain-to-feedback ratio and gives more channel control. Yet natural voice intelligibility is preserved. The mic also has very high SPL capabilities. You can both speak and sing into the mic with no hint of distortion.
