The Hamilton Buhl MPC-29PC-8VF 8-User Mono Listening Center provides you with a terrific way for up to 8 users to enjoy audio for group learning. The system includes 8 sets of MPC-2900 headphones, an 8-user jackbox and a durable plastic carrying case. Each set of MPC-2900 mono headphones has an adjustable headband for a snug, comfortable fit. The washable, replaceable ear cushions fit around the ears for comfort and to block out unwanted ambient noise. The single-sided coiled cable provides a variable amount of slack and minimizes tangles. It has a clip-in design for easy replacement. The cable terminates in a standard 1/4" plug for connection to the jackbox.
The jackbox is a compact unit that allows all 8 sets of headphones to connect to the same audio source. It has 3.5 mm and 1/4" plugs, so it can connect to the headphone jack of virtually any consumer or professional audio device. It then splits the audio signal to 8 individual 1/4" headphone jacks, each of which has its own volume control for convenient adjustments.
The durable plastic storage case has enough room to safely store all of the components of the listening system. It has a toolbox-style design with secure clasps to prevent accidental opening. There is also a padlock hole, so you can add a lock to prevent unauthorized access. A folding handle on the top of the box provides convenient portability.
