Vocal health is becoming a huge topic for teachers these days, but most systems are expensive and have to be installed by professionals-but here is a less expensive alternative. The Samson XP106wDE is a lightweight, portable, wireless, but powerful system that can be placed anywhere in the classroom, rehearsal room, or auditorium so that you can be heard without having to raise or project your voice over an active classroom. The speaker is rechargeable (no wires!) and the unit comes with a wireless headset for freedom of movement. Perfect for the music educator in a lively musical classroom!
