New! Now available for mobile devices and computers using 4-pole (TRRS) combo connector, these are professional miniature mono Omnidirectional and Cardioid (unidirectional) condenser lapel (or musical instrument) microphones with high quality shielded cables. The sound quality of these microphones far surpasses the built-in microphones on these devices.
This clip-on lapel mics provides crisp, full-sounding voice pickup. They also excel as an instrument mic, especially for pickup of acoustic guitar with the optional AT8444 guitar adapter. Excellent gain before feedback and suppression of background noise.
