Details: The Buzz! Buzzer is a special controller designed specifically for the Buzz! quiz game series. The controllers feature large red buzzer buttons and four smaller coloured buttons for answer selection. Both wired[6] and wireless[7] versions are available and come bundled with Buzz! games. A four-buzzer set acts as a single USB device and connects a USB port on the PlayStation 2. Wireless versions connect via a USB dongle, with each dongle able to support up to 4 wireless buzzers at a time. A second dongle is required for additional buzzers (for 8 player games). Both the wired and wireless versions of the buzzers are compatible with both PlayStation 2 and PlayStation 3. The "big button controllers" available for the Xbox 360 heavily resemble buzzers in many respects, and fulfil the same function.
