Calfione's Titanium Series Washable Headphones feature durable ABS plastic construction that lets you easily wash the housing without fear of damage. The adjustable headband and comfort strap keep students comfortable while they listen, and the foam-filled PVC ear cushions ensure ambient noise reduction. Volume control on the cord allows for easy noise level adjustment. A built-in sound control switch makes it easy to keep the sound level at or below 85 decibels to protect your student's hearing. USB connectivity lets you interface with both Macs and PCs. Detach the six-foot polyurethane cord before washing.
