Audio on the Cheap

8200-hpThere’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.
