Hamilton Electronic's personal educational headphone with leatherette ear cushions are the first headphones designed to combat the spread of head lice in schools. Each headphone comes in its own heavy-duty reclosable bag which, when sealed, kills lice in 24-48 hours without the use of chemicals. Write on bags with student's name and headphone now comes in easy to write-on, medium gray colors.
Now featuring Hamilton's exclusive ASM™ automatic stereo/mono technology (patent-pending). With ASMt™, these headphones can be safely used with virtually all school audio equipment.
