Classroom Amplification
There’s nothing worse than not being able to afford
enough headphones for the whole class to use at once because the alternative is
a cacophony of sounds from the variety of educational devices. Califone’s
8200-HP headphones cost just $10 each or $180 for 20 of them. Still, they have
an adjustable polypropylene headband, a pair of 30mm mylar speakers that can
create sounds from 20 to 20,000 hertz and connect via a 3.5mm audio jack. The
headphones weigh 3-ounces and have comfy foam ear cushions.
