The Nintendo GameCube WaveBird Controller

Shortly after the release of the GameCube, Nintendo created the WaveBird controller. The controller is exactly the same as the regular GameCube controller except that it's wireless and the vibration function was removed. The vibration was removed to keep power consumption to a minimum. The controller runs for an impressive 100 hours using two AA batteries.

The WaveBird is notable for being the first, best and so far only wireless first-party controller. Signal dropouts are virtually non-existent, and the controller can be generally expected to operate to a distance of 50 feet.

The WaveBird wasn't the first wireless controller, but it's the first one that works just as good as the default controller - except that it's wireless.
