    Abstract: This disclosure relates to a device and a method for controlling sound play, and a system associated therewith. The device includes a brainwave detector, a selector and a switcher. The brainwave detector is arranged to detect brainwave information of a user. The selector is arranged to select a sound player to be used from a first sound player and a second sound player based on the brainwave information. The switcher is arranged to send a switch control signal according to a result of the selection so as to cause the selected sound players to play the sound. By selectively switching on a sound player based on the brainwave information of the user, the sound play mode adapts to personal state or expectation of the user.
