The Hamilton Buhl LCP/30/MS2L headphone lab pack is a great choice for use in schools. This kit comes with 30 sets of MS2L headphones, allowing you to eliminate headphone sharing between children, reducing the spread of head lice. Each pair of headphones has its own re-sealable 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. The headphones have a standard 3.5 mm mini plug and a 1/4" adapter for use with all types of audio gear. A lockable plastic case is provided for storing the headphones.
