The JB8V-BT 8-Position Bluetooth-Enabled Stereo Jackbox from HamiltonBuhl is a device that delivers stereo sound to headphones for up to 8 students and includes volume controls for personalized headphone listening levels. It can be used wired or from a Bluetooth-enabled device like a smartphone or tablet to send an audio signal to the jackbox in a classroom or other group environment.
The JB8V-BT is constructed from heavy gauge plastic and can be daisy-chained with up to two additional units via wire connection for a total of 24 listeners. In addition, a digital readout shows the unit's battery level, preventing the chance of running out of power while presenting. A power supply and a 3.5mm audio cable are included.
