The Audio Enhancement Infrared Teacher Teardrop Microphone, powered by Panasonic, brings a level of convenience to the classroom. The IR Teacher Teardrop Microphone is a lightweight, wearable microphone that distributes the teacher’s voice across the room. With a revolutionary patented remote control feature, the teacher is able to control the volume of his or her microphone, the optional student microphone, or the auxiliary input level. Teachers, administrators, and students will appreciate the high quality performance and ease of use.

One unique feature of the Audio Enhancement microphones is the Microprocessor Intelligent Charge, or M.I.C. It’s our solution to the problem of dead, burned out batteries and microphones becoming damaged by incorrect charging. M.I.C. has been a feature of the Teacher Teardrop Microphone and the Student Handheld Microphone since 2006, and has saved literally thousands of systems over the years from costly repairs and the need to replace batteries. Now you can take battery charging concerns off of your list of things to worry about; your Audio Enhancement classroom infrared system has it all covered with M.I.C.
