The Califone NC500TFC headphones provide high-quality audio and a high degree of noise isolation in a comfortable design. Ideal for use in schools and other environments where ambient noise can be a distraction, these headphones allow you to focus on music, lectures, or lessons without being disturbed by outside audio. The padded, adjustable headband and thick around-ear cushions provide lasting comfort. The cushions also help to naturally block out noise, even if the headphones are turned off.
The active noise cancellation technology in the headphones provides even greater noise reduction than the earcups alone. The circuitry operates on a pair of standard AAA batteries. If desired, you can turn off the cancellation technology to use the headphones in passive mode. You can also detach the single-sided headphone cable to block out ambient noise without listening to music. The single-sided cable keeps tangles to a minimum and features an inline volume control for making quick adjustments. It has a standard 3.5mm mini plug with a 1/4" adapter for connecting to a variety of consumer and professional audio devices. The headphones feature a fold-flat design for convenient storage in the included hardshell case.
