External laptop speakers are stand-alone speakers connected to a laptop computer through a USB port or by a wireless connection to play sound. External speakers increase the volume and quality of sound from laptops, which typically do not have high quality speaker systems.
External laptop speakers are purchased as either a pair, a pair with a sub woofer or as a surround sound set that includes five to seven speakers and a sub woofer. Prices vary based on available features. These features include whether the set has wireless capability, a mute button, an auxiliary input for plugging in MP3 players, a remote control and the ability to control bass and treble levels.
