The CLS721 Wireless Mono Headphones from Califone are ideal for use in classrooms and other institutional venues. The headphones use RF technology to receive wireless audio from a receiver (sold separately) from up to 100' away! The headphones come tuned to 1 of 4 different color-coded frequencies, providing the potential to set up 4 different audio programs in the same area without crossover or interference. An unlimited number of headphones may be used with a transmitter.
The headphones are constructed from durable ABS plastic. Featuring an adjustable headband and easily-cleaned around-ear cushions, the CLS721 provides long-lasting comfort. A built-in volume control allows each listener to select their own loudness without affecting others in the group.
