Califone 3068AV Switchable Stereo/Mono Over-Ear Headphones provide the best of both worlds. Equipped with noise reducing capabilities, leatherette cushions, and size adjustability, these earphones give optimal listening performance. Users can switch between monaural functions typical for ELL/ELD lessons, to stereo requirements typical of computer workstations and online learning. A padded headband on the headphone set is fully adjustable to fit most sizes, including children and adults. The volume control on each ear cup offers additional comfort and enhanced hearing. Made for all ages, the highly durable CaliTuff cord is made of braided, PVC-jacketed material with a reinforced earcup entry point. It resists bending, cutting, and separation due to heavy use, chewing, or playing. The extra-long 10-foot cord has a 3.5mm plug and 1/4 inch adapter for compatibility with Chromebooks, laptops, desktops, PCs, Windows, and Macs. This wired headphone is backed by a 3-year warranty.
