The Hamilton Buhl HMC/CD385/4SV Headphone Lab Pack is a great choice for use in schools and other institutions. This kit comes with an MPC-5050 boombox, which plays both CDs and cassette tapes and also offers an AM/FM tuner. It has repeat play and can operate via eight "C" batteries, or with an AC wall adapter.
The set also includes four sets of HA5 headphones, allowing you to eliminate headphone sharing, reducing the spread of head lice. The headphones have an adjustable headband to fit any head size and the washable, replaceable leatherette ear cushions provide comfortable listening. The headphones have single-sided coiled cables with standard 1/4" plugs.
The included jackbox allows you to connect each of the pairs of headphones to a single audio source. The jackbox has plugs for both 1/4" and 3.5 mm jacks, so you can connect to virtually any CD player, tape player, DVD player, TV, VCR, or computer. It also has individual volume controls so each listener can control their volume without affecting others. A lockable plastic storage box is included for stowing the system when not in use.
