Prevent The Spread of Lice:

Built with kid's health and safety in mind, these headphones are designed to combat the spread of head lice in schools. Each headphone comes in its own heavy-duty, write-on, moisture resistant, reclosable bag. When sealed in the bag, lice is killed in 24-48 hours without the use of chemicals.

Automatic Stereo/Mono Smart Technology:

Exclusive automatic stereo/mono technology that allows these headphones to be used with virtually all school audio equipment. Never worry about mismatching headphones between different sources and damaging ears or equipment. No switches to set or special plug adapters to change - the headphone knows if it is plugged into a stereo or mono system and automatically adjusts. Operates in 1/8" stereo, 1/8" mono, 1/4" stereo or 1/4" mono modes.
