This Active Noise Cancelling headphone sets the classroom standard when high stakes testing requires the quietest of individual settings. Califone understands the importance of blocking out external classroom noise has different implications than tuning out background sounds while on an airplane. This is why we've designed our NC500TFC to be used by itself to negate outside distractions, or when plugged into a computer or media player so students will be able to discern the subtle nuances in language learning for instance.
The ability to block background noise when coupled with this innovative technology, provides the utmost in sound quality and speech clarity, and makes the NC500TFC ideal for use with computers, learning centers, and personal audio players.
The secret behind the sound is a proprietary technology which alters the audio signal to make it easier to hear high frequency words or notes where clarity is often lost. The technology also increases the perception of loudness at the same time without actually increasing the volume. Previous technologies struggled to replicate the “live” experience because bass sounds masked the high tones. This made speech difficult to hear and made music sound muddled.
The sound enhancement is made possible by creating high frequency harmonics that are not masked by low frequency sounds; filtering undesirable noise and reducing distortion. In the process it also provides for clearer sound and improved speech clarity even at lower volumes. This will encourage students to reduce the level of playback with the in-line volume control to a safe listening level to preserve hearing.
The headphone is also the most comfortable in the award-winning line of classroom quality listening devices. Upgraded leatherette earpads and the lightweight ergonomic design help make the NC500TFC comfortable for extended periods of time.

A: The NC500TFC active noise cancelling headphone helps protect students’ hearing with its large over-the-ear earcups that reduce ambient noise even before the noise-cancelling feature is activated. To activate the noise-cancelling feature built, simply turn on the on/off switch located on the earcup. The lit green LED light next to the on/off switch provides a confirmation that the noise cancellation is active.
A: The NC500TFC active noise cancelling headphones are only available with its hardshell storage case as the headphone earcups allow it to fold flat inside. Storage cases help protect headphones and other audio visual equipment.
A: The difference between a headphone and a headset is a headphone is used only for listening and a headset can be used for listening and capturing audio responses (used by many language/reading programs). Put another way, a headset is a headphone with a microphone attached to it.
