The Califone Titanium Series HPK-1040 Washable Headphone with 3.5 mm Plug is the first of its kind that can be completely immersed in soap and water (after its cord has been detached) for washing. Once cleaned and thoroughly dried, simply reconnect the body to its replaceable cord and the Titanium headphone is ready for reuse. The HPK-1040 helps students focus more effectively on the task at hand by blocking the highest amount of ambient (external) noise of any passive headphone, which Califone has ever offered.
School budgets can't afford equipment that won't last the entire year or cause lost learning time and that's why the HPK-1040 is built using more rugged ABS plastic (even its cord is thicker than previous models). But longer lasting doesn't automatically mean student comfort, which is why the ear cushions have also been upgraded to be just as long lasting, but feel softer without the accumulated clammy feeling which can come after prolonged use.
