The LCB/12/MS2LV headphone lab pack from Hamilton is a great choice for use in schools. This kit comes with 12 sets of MS2LV headphones, allowing you to eliminate headphone sharing between children, reducing the spread of head lice. Each pair of headphones has its own resealable bag, which kills lice within 48 hours without chemicals. The headphones have an adjustable headband to fit any head size, and the leatherette earpads provide comfortable listening.
The headphones can automatically detect whether they are plugged into a mono or stereo audio source, so you can plug into any piece of equipment without worry. A built-in volume control in the cable allows the listener to control his or her own volume level easily without affecting others. The headphones have a standard 3.5mm mini plug and a 1/4" adapter for use with all types of audio gear. A laminated cardboard case is provided for storing the headphones.
