The Cherry Heaven USB Stereo Loudspeakers don't need batteries or a mains power supply: they're powered by the computer's USB socket and driven by the stereo-out socket. They don't need installing or setting up, and are compatible with Windows 98, NT, ME, 2000, XP, and Vista.

The Cherry Heaven USB Stereo Loudspeakers are dark grey with black cloth. They measure 82mm x 82mm x 127mm. The USB power cable is 1.8m, the audio cable is 1.8m, and the left-to-right connecting audio cable is 1.4m. One speaker has an on-off rotary volume control and a blue power-on LED.

Although notebook computers have built-in speakers, they're often small and sound poor. Extension speakers improve the volume and tone, and provide a better spacial stereo effect if you're watching a movie.

Loudspeakers are used for home entertainment, demonstrations, presentations, recording, broadcasting, performance, games, language learning, internet chat, and computer telephony applications such as Skype.
