Extron VLH 302 (part number 60-1703-01) — the wireless handheld microphone for Extron VoiceLift Pro classroom voice amplification systems.

Handheld microphones in schools live a hard life: passed between students, put down mid-sentence, occasionally dropped. Extron builds this one accordingly, in polycarbonate, with a collar that stops it rolling off a bench and a power switch designed to be easy to find but hard to knock by accident. An auxiliary jack on the body accepts an unbalanced stereo source such as a media player, so background audio can be sent through the same reinforcement path.
